Basement Waterproofing with Epoxy Part 2A

September 15, 2014

Poured Concrete Foundation Waterproofing

This is number 2A of a 2 part series on basement repairs. In Part 1, we discussed waterproofing block wall foundations. In Part 2A shows how to identify leaks that need waterproofing in basement walls, and floors that are made out of poured concrete. Part 2B will deal with the actual repairs to poured concrete leaks.

In our last piece we discussed how many homes and businesses experience leaky basements year after year. The worse time is in the spring after winter accumulation of snow. There are a number of prudent things that you can do to improve drainage against your foundation like roof gutters, grading and improvement of drainage. The recommendations here do not replace that conventional wisdom. It is designed to augment and improve upon these conventional methods.

Identifying the Source of the Basement Water Leak

The nice thing about poured concrete is that it holds water back very well. The leak typically happens at a cold joint or in a crack or hole in the concrete.

Concrete Cold Joints

Fresh (plastic) concrete doesn’t bond to hardened concrete. The exception is when a special epoxy bonding agent like Epoxy.com Product #2007 – is used (this bonding agent will be discussed in a future article). When concrete has hardened or has started to harden and you pour more concrete against it (without the right bonding agent) you get what is called a cold joint. These cold joints are a common source of water leaks.

Virtually all basements are built with a giant cold joint – the cold joint between the floor and the wall. Typically there is some sort of water-stops material installed in these joints intended to stop leaking at this cold joint. These water-stops can fail. So the wall to floor joint in a concrete basement is a frequent source of water leaks.

You can also get cold joints in the middle of concrete walls and floors due to multiple pours. You can get cold joints if concrete is setting to fast and fresh concrete is poured against semi cured concrete. Sometimes saw cuts in the floor can be a source of leaks

Form Ties

Then there are the ties that go through the concrete to hold the forms together on either side during the pour. If these form ties are not installed perfectly or if the concrete is not totally vibrated around them, these ties can act as a conduit to let the water in.

 

Wall and Floor Cracks

When concrete cures it shrinks that is called “plastic shrinkage”. That plastic shrinkage can and usually does result in the concrete cracking. These cracks are one of the easiest ways for water to get into your basement. If the water makes it to the fill side of the tank (under the floor or against the wall) it will typically leak out into your basement. You should look carefully for these cracks when looking for potential leaks into your basement. If you are able to investigate into the water infiltration into your basement when it is leaking it will be easy to see. If trying to find the source of leaks when the basement is dry you have to look for water marks on either side of the cracks and beneath the areas that might be leaking.

Repairing the Basement Leaks with Epoxy

In the next installment on this topic, I will deal with how you waterproof the cracks while structurally repairing them with epoxy and similar materials.

Basement Waterproofing with Epoxy

September 4, 2014

Many homes and businesses experience leaky basements year after year. The worse time is in the spring after winter accumulation of snow. There are a number of prudent things that you can do to improve drainage against your foundation like roof gutters, grading and improvement of drainage. The recommendations here do not replace that conventional wisdom. It is designed to augment and improve upon these conventional methods.

The following article will be 1 of 2. This one deals with Block wall foundations. The next one will deal with poured wall foundations.

Waterproofing Block Wall Foundations with Epoxy

One of the nicest features of most of our epoxies are that they are virtually 100% waterproof. Water simply cannot pass through a good healthy layer of properly applied concrete, block, wood etc. Epoxy also has an incredible bond to concrete, cement, wood and many other construction materials. The bond strength of epoxy to concrete and cement is greater than the tensile strength of the concrete. That means on properly prepared concrete, epoxy cannot be removed without pulling concrete with it. The same is true about wood.

Considerations in Waterproofing with Epoxy

All this gives you the perfect combination to make a block wall watertight. There are limitations however:

  1. In an ideal world the epoxy should be applied on the positive pressure side of the wall, the outside. This way the pressure of the water is pushing it into the wall. That helps to mitigate the likelihood that you get so much pressure on the concrete block that you fracture the block. Typically by the time you know you have a leak you are already backfilled and landscaped so 95% of the time it is not practical to do on the outside of the wall. So you do it on the inside instead.

    Water exerts a pressure of less than ½ psi per foot of water depth and most basement walls are only 8 foot high, so you would typically only see 4 psi. So it is unlikely that you have a pressure greater than the tensile strength of the block. So doing it on the inside is typically the only economical alternative.

  2. The Product #1W Epoxy is much more flexible than the concrete block and mortar, but if the mortar or concrete gets any significant cracks in it, it will crack through the coating. On the other hand, the system is very easy to patch if it does crack. We also make a wall grade version of our crack isolation membrane Epoxy.com Product #32 – www.epoxy.com/32.htm – which can reduce the potential for small cracks (which are the most common).
  3. A clean substrate is required for maximum effectiveness – www.epoxy.com/surfaceprep.aspx. For technical support contact me at norm@epoxy.com or 352-533-2167

Installation of Epoxy Waterproofing on Block Walls

Once the wall is clean, you need to point-up (fill) any cracks, bad mortar joints, and larger holes that are in the block. Some people use conventional mortar and wait 28 days for it to cure as per the American Concrete Institute. This is a very inexpensive way to do it, but can be affective if done properly. A more effective way to insure the right results is the use of Product #2005 Epoxy Gel Adhesive – www.epoxy.com/2005.aspx. That insures that you have a tight bond over the cracked areas and have already produced a tight waterproof seal in that area. Also the #2005 Gel Epoxy is semi flexible and allows more movement before cracking that conventional grout. The #2005 allows your coating to be installed the day after the #2005 is applied.

Once the cracks and holes are repaired, much of your work is done. You simply apply 1 coat of Epoxy.com Product #899 – www.epoxy.com/899.aspx – Epoxy Primer and allow to dry overnight.

After the primer has cured overnight you can apply the optional crack isolation membrane Product #32W – Wall Grade, or proceed to the coating below. If you do apply the crack isolation membrane 2 coats of the membrane are best. One advantage of the two coats of membrane is that typically you can reduce the number of coats of top coating that is required to seal the block. As you put on the membrane be sure to check to see that the holes in the block are being filled as you go.

Depending on the porosity of your concrete and if you used the crack isolation membrane above you will want to apply 2-4 coats of 1W epoxy wall coating. As you put on each coat check to see that the holes in the block wall are being filled.

Summary of Waterproofing Basement Walls with Epoxy

In conclusion: Leaking basements are a major problem to many structures in the spring. The easiest time to repair them is during the winter when there is little or no leakage. Epoxy.com epoxy coating systems can affectively and economically solve most basement leaking problems. The final product is a hard attractive ceramic like finish that does not require additional painting or other finishes over it.

Seamless Epoxy Flooring Systems Explained

August 25, 2014

Epoxy.com offers many different types of seamless flooring. We offer so many kinds that sometimes it confuses people. The purpose of this article is to explain the differences, and to help you choose the right epoxy seamless flooring system for your application. In some cases the right seamless flooring system will not even be an epoxy. It may be polyurethane or Methyl Methacrylate (MMA).

Epoxy.com Epoxy Chip Flooring in VT rest area.

Epoxy Floor Coatings

Epoxy coatings can be effective flooring systems. Using Epoxy as a flooring system you need a 100% solids, zero voc, hard durable coating. You also want a coating that is available in multiple colors. These floor coatings can last for decades, so you want to pick a color that you like. Properly installed you will be looking at this floor coating for a very long time. This kind of flooring system is available in the following options:

  1. Epoxy.com Product #1 – www.epoxy.com/1.htm – meets all the criteria above. It has good chemical resistance, and excellent cost to benefit ratio. Great for warehouses, in areas with high traffic and only modest chemical exposure.
  2. Epoxy.com Product #1ESD – www.epoxy.com/1esd.aspx. This is the same as product #1 above but has conductive filler in it. Depending on the primer you use under this system it can be conductive (100,000 – 1,000,000) ohms of resistance or Electro-Static Dissipative (ESD) which is 1,000,000 to 1, 000,000,000 ohms. Used in plants that produce explosive materials like ammunition, fireworks, flairs, or explosive solvents, and used in areas of sensitive electronics, like computer server buildings, avionics, electronics assembly and electronic production areas.
  3. Epoxy.com Product #2 – www.epoxy.com/2.aspx. This is similar to product #1 but with a much higher chemical resistance. This major increase in chemical resistance is offset by only a small increase in the cost of the #2 over the Product #1. The product #2 is well suited for applications like garages, machine shops, sewer tank floors, battery rooms, cooling towers, grooming shops, dog kennels and all areas where an economical chemical resistant coating is required.
  4. Epoxy.com Product #633 – www.epoxy.com/633.aspx – is a highly chemically resistant epoxy floor coating and flooring system. Like Product #1 and Product #2 is extremely durable. Product #633 is typically used in areas where containment of aggressive chemical is imperative. For example Product #633 will hold up to continuous exposure of 98% Sulfuric acid for a period of at least 6 months without loss of structural integrity. Great for secondary containment for a large number of chemicals.

     

All the systems above can go over many different types of substrates with the proper surface preparation. All of the products above are available in 17 colors and can be color matched for an additional cost. The systems above can be combined with various anti-skid materials or broadcast with silica broadcast aggregate to produce a thicker floor

 

Chip Floor

Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx – is the perfect blend of economy, durability, low maintenance, and gorgeous appearance. It uses a 100% solids pigmented epoxy base coat, a full broadcast of plastic chips, and two coats of chemical resistant clear glaze. The chemical resistant glaze also makes this easily the most non-yellow epoxy top coat available today. This easy to clean chip flooring system is best for high traffic areas where appearance, durability and low cost of ownership is a must. Great for commercial and residential kitchens, bathrooms, showers, grooming shops, kennels, veterinary clinics, garage floors, show rooms, rest areas, and much more. This product can be installed with an integral cove base. Epoxy.com Chip Flooring can be installed by a contractor but easy enough to be installed by a home owner. Epoxy.com Chip Flooring can be installed in a residence but is rugged enough to be used in the most demanding commercial applications.

Quartz Flooring

Quartz Flooring Product #15 – www.epoxy.com/15.aspx has a long history of being durable, attractive and non-yellowing. I personally installed this product on high school bathroom floors in the mid 70s. These floors have held up to the test of time with little or no wear, little or no loss of shine and little to no yellowing even under the urinals. This is also available with an integral cove base

Solid Colored Flooring

These solid colored floors are based around self leveling, trowelable or double broadcast application techniques. These floors are sometimes called shop floor. They are made to be thick and extra durable under extremely harsh environments. They can be top coated with any of the systems above under coatings. This kind of flooring is available in 3 speeds of cure: normal, fast, and cold cure. Solid colored flooring is also available with an integral cove base.

Methyl Methacrylate (MMA) Flooring

The big advantage of MMA is speed of curing. Each coat of MMA will cure hard to the touch in 1-2 hours. This allows the next layer to be applied quickly and traffic to be returned to it quickly. You can even build a fast setting integral cove out of MMA resin.

I personally installed MMA on one kitchen floor with a very tight schedule. The restaurant was only closed for breakfast. The project started with rotten plywood floors. At 10 PM the carpenters came in to work. They removed rotten floor and floor joists. They replaced the floor joists and the plywood. At 5 AM I went in with my crew and we primed the floor and sealed up the joints in the wood and the screw holes. At 6:30 AM we laid the floor. At 8 we put a glaze coating on the floor and by 10:30 the restaurant workers were on the floor prepping for lunch. The floor installation from start to traffic took just 5.5 hours.

Polyurethane Decking Systems

Polyurethane Decking – http://www.epoxy.com/elastomeric.aspx – is the system best used in areas where maximum flexibility is necessary. This is typically outdoors, waterproof applications like balconies.

Specialized Flooring

We have a number of systems that are specialized flooring like conductive and ESD (Electrostatic Dissipative) flooring – www.epoxy.com/conductive.aspx – and various hybrid systems. If your project does not seem to fit in the categories above email me at norm@epoxy.com or call us at 352-533-2167.

 

In conclusion we offer many types of seamless flooring systems, they can be used for commercial and residential applications. These systems are durable, economical, and easy to install even by homeowners. These seamless flooring systems may be made out of epoxy, polyurethane, or methyl Methacrylate (MMA).

August 8, 2014
epoxy-Deck-after-2

Epoxy Patching Mortar #10 for patching. Coated with Urethane Decking System #495.

Epoxy.com Product #10 is a versatile resin for use in epoxy floor patching. Product #10 comes in standard cure, fast cure and cold cure. It can be used with 3 different aggregates: self leveling, mortar blend, and broadcast aggregate. Product #10 is available in 15 colors plus black and white making a total of 17 colors available. Custom colors are available at a small additional cost.

The Epoxy Cures

Normal Cure at 77 degrees F. has a pot-life (the usable time after mixing) of about 30-40 minutes. It hardens to the touch in about 10-12 hours. Normal Cure should never be used below 50 degrees F.

Fast Cure at 77 degrees has a pot life about 15-20 minutes. It hardens to the touch in about 5-6 hours. At 50 degrees F the Fast Cure hardens to the touch in 10-12 hours. In other words the Fast Cure at 50 degrees will cure as fast as normal cure at 77 degrees F.

Cold Cure at 77 degrees F. has a pot-life of about 8-10 minutes. It sets hard to the touch in about 2.5 to 3 hours. At 50 degrees F the cold cure will typically cure in 5-6 hours. It is able to cure at temperatures as low as 35°F.

The Aggregates

The aggregates come separately from the Product #10 resin and hardener. That allows you to be able to use a unit of resin with multiple aggregates making the system even more versatile.

Mortar Blend Aggregate Product #82 is the work horse of floor patching. You can get up to 50 lbs or more of Product #82 into a mixed gallon of #10 epoxy mortar. This is ideal for deep patching.

Self Leveling Filler Aggregate Product #78 is used for self leveling applications, typically in thicknesses of 1/16 inch plus or minus. This is ideal where a thinner flat overlay is required. A typical use would be where a floor needs to be leveled. Another typical use would be for a “scratch coat” which is where you are trying to cover large amounts of chips and divots in the floor.

Broadcast Aggregate Product #77 is broadcast into wet #10 in order to produce an anti-skid surface. It can be broadcast into a neat coat (just the resin and hardener mix without the aggregate) of #10 or into the Mortar Blend Aggregate or Self Leveling filler systems above.

In addition to being able to mix the #10 with the fillers above, you can also mix it with Product #71 Fumed Silica to make a paste for cracks and other small imperfections.

 

In summary the Epoxy Mortar Resin Product #10 is a versatile epoxy mortar system available in many colors, several cures and different fillers for different purposes. This makes Product #10 an important part of your floor repair tool chest.

Waterproof Your Life

August 7, 2014

The Concept

About 20 years I had a half way house that came to me and wanted a virtually indestructible waterproof group bathroom. They needed it to be like a shower enclosure for the entire bathroom, and toilet facility. It needed to be easy to thoroughly clean and disinfect.

The resulting system allows you to hose down the entire ceiling, wall and floors. The system that we developed is a completely seamless, waterproof ceiling and coating system. This epoxy ceiling and wall coating is seamlessly integrated with a seamless flooring system. This system is now being used for everything from clean rooms to animal facilities to car washes, daycare centers, assisted living facilities, food processing facilities and more.

The System

Ceiling and Walls

Prime the ceiling and walls with Epoxy.com Product #899 Primer – www.epoxy.com/899.aspx. Product #899 Primer is a 100% solids, low viscosity, moisture tolerant epoxy. It soaks deeply into the substrate, verifies surface preparation, and helps to prevent the much thicker coating from getting bubbles that may be cause by air or moisture trying to escape from the substrate during curing. Allow primer to get hard to the touch.

Before the epoxy primer is 24 hours old (and after the primer is hard to the touch) apply a coat of Epoxy.com Product #1W. The 1W – Wall Coating is 100% solids. It comes in a range of different colors. This means it is zero (0) VOC with no solvent. Just like the 899 Primer the 1W has very little odor. We have even more chemical resistant wall coatings for applications where it is chemicals that are being splashed or sprayed. Contact us if you have strong chemical exposures that you want to contain instead of water.

Let the first coat harden to the touch and before 24 hours add another coat of #1W. Allow the coating to dry over night.

Seamless Epoxy Cove – Optional

Typically the cove is only installed if you are going to install one of the multi-colored flooring systems (Waterproof Floor Options 2 & 3below). Cove is covered in an earlier blog – https://news.epoxy.com/2014/06/25/seamless-epoxy-cove-installation-instructions/. The cove gives you a radius at the bottom of the wall making the floor to wall transition easy to clean and esthetically pleasing.

Seamless Epoxy Flooring System

There are multiple systems that you can use for your seamless flooring portion of the system.

Water Proof Floor Option 1 – Seamless Epoxy Floor coating:

Floor Coating Systemwww.epoxy.com/1.htm. Product #1 applies with the Product #899 primer under it and in 2 coats just like the 1W. The Product #1 is thinner and flattens better on a floor than the Product #1W. You can also add an optional anti-skid to the #1 Floor Coating. The #1 comes in all the variety of colors of #1W.

Waterproof Floor Option 2 – Seamless Epoxy Chip Flooring:

Chip Flooring Systemwww.epoxy.com/chip.aspx is a two component 100% Chemical Resistant Epoxy Chip Flooring. System #315 Seamless Epoxy Multi-Colored Chip Flooring is available in virtually limitless color combinations. If your job is big enough our chips can be pigmented to match all the colors of many major paint companies. We can color match our base coat colors as well. Unless the pigments for your custom colored 315 Basecoat are unusually expensive we can color match for a modest small batch charge or at no charge for larger orders. Even our standard color pallet offers you over 45 chip colors that can be blended in any combination and percentage as you want. This gives you the architectural choices you need. The top coating for this system is highly UV resistant so since it doesn’t chalk indoors it can last and look great for decades.

Waterproof Floor Option 3: – Seamless Epoxy Quartz Flooring:

Quartz Flooring System with Product #15 – www.epoxy.com/15.aspx – is also an excellent flooring system for those who like the colored sand look with a good midrange chemical resistant system.

Waterproof Floor Option 4 – Seamless Chemical Resistant Flooring:

We can also help you to combine the systems above with our Novolac Epoxy Systems – www.epoxy.com/novolac.aspx for highly chemically resistant versions of those systems. You can also install an Electro-Static Dissipative or Conductive system www.epoxy.com/conductive.aspx.

 

In conclusion the systems above are only a small fraction of the possibilities. With our wide range of colors and chemically resistant systems the possibilities are endless. Please contact Epoxy.com Technical assistance at 352-533-2106 or email me directly at norm@epoxy.com.

Today’s Resin

The Right Resin System for the Right Job


We want you to have the “Right Resin Product for the Right Job”, so we are always looking to improve our systems with new epoxy technology and new epoxy resin formulations. Today we are featuring a Methyl Methacrylate MMA not an epoxy.  We are not just about epoxy but we want you to have the right resin system for your job.

 

MMA Concrete Crack Healer and Sealer

684LV – MMA CONCRETE CRACK HEALER and SEALER replaces Epoxy.com Product #685.  MMA CONCRETE CRACK SEALER Product #684LV is a 100% reactive ultra-low viscosity methyl methacrylate resin used as a penetrating crack sealer or to fortify extremely porous concrete substrates. MMA CONCRETE CRACK SEALER Product #684LV is typically used on bridge decks, parking structures, and floors or as a general penetrating sealer to prevent moisture intrusion.

One of the major advantages of MMA CONCRETE CRACK SEALER Product #684LV is its very low viscosity.  It is about the viscosity (thickness) of diesel fuel, so it soaks into the concrete and down into small cracks quickly.  It hardens in about an hour.  When it hardens it hardens with a bond strength to clean concrete that is greater than the tensile strength of that concrete.  In other words you have just chemically welded the two sides of the crack together, so that it is as if the crack had never happened.

The very fast setting time allows you to install you flooring or sealer system the same day that you repair your crack. At Epoxy.com we are all about systems.  Combining the right resin product to create the right system for your job.
