The following article is written with enough information about resin injection systems to help protect the Owner from the misuse or improper installation of an injection systems.   For more information contact me: Norm Lambert.

This is the second in a series on Infrastructure Repairs Using Epoxy. Part One was Introduction to Epoxy Injection.  If your have not read that yet you may want to go back and read it before you proceed with reading this.

Part 2: Crack Analysis Before Epoxy Injection

As with all repair and rehabilitation of concrete, the initial job analysis is by far the most important step. Epoxy Injection Resin will weld concrete cracks but, of course, will not repair the cause of the cracking.

Analyze each potential injection application to determine the exact cause or causes of the cracking. Correcting the cracking problem can be fairly simple, or may be difficult involving design changes.

Consult a structural engineer when design changes are necessary. Do this before starting the injection. Repairing cracks by Injection is effective after these design changes. Prevent future cracks by fixing the original cause of the cracking, when ever possible.

Parking garages are an example of cracking problem that require a structural engineering analysis.Epoxy.com Epoxy Inection Often inadequate design for expansion/contraction is the cause for parking garage structural cracking. Avoid weld injecting a crack if there are not enough expansion joints. Sometimes flexible overlays such as Epoxy.com System # 495 can be used to overcome this defect. This does not however encapsulate the rebar in a way that will totally stop the premature deterioration of the steel. Often times additional joints are needed, thus the analysis of cracking problems is critical.

Bridge decks and slab on grades can often be repaired with Epoxy.com Product #684LV crack healer and sealer and save some of the cost of doing epoxy injection.

Part 1: Introduction to Epoxy Injection

Epoxy Concrete Injection Epoxy Wood Injection, epoxy crack repair

One of the most versatile, problem solving products available in epoxy systems today is Epoxy Injection Resin. Epoxy.com Epoxy Injection of a bridge abutmentStructural restoration of concrete by epoxy injection is very often the only alternative to complete replacement. It therefore results in large cost savings. Injection protects the rebar and stops water leakage.

Epoxy injection of concrete cracks has been used for decades. When properly installed it is still working as well as it did right after it was installed.

Epoxy Injection Resin is a system for welding cracks back together. This welding restores the original strength and loading originally designed into the concrete. Epoxy injection restores the structural qualities the concrete design intended. In other words under most conditions it makes the concrete as good as new. It creates an impervious seal to air, water, chemicals, debris, and other contamination.

Other waterproofing injection systems like urethane resin will seal the crack from water but will not repair the the member structurally.  That makes the structure member vulnerable to additional structural decay. This structural advantage that an epoxy injection repair gives, makes it the best choice for most situations. Epoxy or Urethane Injection discusses when to use epoxy and when to use urethane.

A crack, obviously, is a sign of failure caused by stresses, inadequate design, improper curing, etc. One of the dangers of a structural crack is the effect that it has on the reinforcing bar. The reinforcing represents one of the main structural values of the concrete.

Cracks left unprepared allow moisture, road salts and other contaminants to penetrate and attack the rebar. The rebar deteriorates, losing the structuEpoxy Injection of concreteral value. Loosing the entire structure is often the result.

Epoxy injection resin has two purposes. First, it effectively seals the crack to prevent the damaging moisture entry. Secondly, it monolithically welds the structure together. Most people assume that this welding of the structure is the most important result of the repair. Actually what is most important is the sealing.

The sealing properties of the injection prevents premature deterioration of the reinforcing. This can be of equal, or in some cases greater importance than the structural welding. It would theoretically always be desirable to get this welding effect.

Secondary Chemical Containment

February 7, 2017

You can easily build containment in the middle of an existing slab

Building a secondary containment structure in the middle of an existing facility is very common and effective way to protect the facility structurally as well as protect the environment.  It is very easy to do.  Here is how:

  1. Grind the area where the curb will go to bare concrete – www.epoxy.com/surfaceprep.aspx.
  2. Drill holes into the concrete and fasten #4 bar into the concrete with Epoxy.com Product #2006 – www.epoxy.com/2006.aspx – Gel Adhesive. Allow Epoxy to cure overnight.
  3. Form the area to receive concrete curb.
  4. Coat the floor area in the bottom of the forms to receive the concrete for the curb with Epoxy.com Product #2007 – https://www.epoxy.com/Epoxy_Fresh_Concrete_to_Hardened_Concrete_2007.aspx – Wet to dry concrete adhesive. Pour your concrete before the #2007 becomes tack free. That will make it as if the curb and the concrete floor had been poured at the same time.
    1. An alternate method to this is to install concrete brick around the area bonding in place with Product #2006. This will help to reduce waiting for the concrete to cure if you use the poured concrete method above.
  5. Allow the concrete to cure – www.epoxy.comsurfaceprep.aspx.
  6. Cove the inside of the containment curb with Epoxy.com Product #720 – https://www.epoxy.com/720.aspx – coving resin allow to cure overnight.
  7. Prime the inside of the containment area with Epoxy.com Product #12– www.epoxy.com/12.aspx  – Chemical Resistant Primer, and allow to cure overnight.
  8. Install 2 coats of Epoxy.com Product #633 – www.epoxy.com/633.aspx – Chemical Resistant Novolac Epoxy Coating.

Cold Temperature Epoxy

Installing Epoxy in Coolers and Cold Temperature

Extend Epoxy Installation Season into Winter

I have spoken on this subject here before but this time of year I get a lot of calls and emails about installing epoxy in cold temperatures. Our company started out as an installation company in Vermont. Summers are very short and winters are very long in Vermont. To stay a viable company, we had to figure ways of working through the winter.

Tenting and heating areas during the winter is time consuming and expensive. The solution is found in resin products that will set in low temperatures. The most durable and cost effective options of installation at cold temperatures is Epoxy and Methyl Methacrylate.

Cold Temperature Cure Resins can also be used as a super-fast setting Resinous Mortar or Coating at normal temperatures. Our Cold Temperature Cure Resins used at normal temperature give you quick turnaround time for small jobs, or larger jobs that require a short turn-around time.

Cold Temperatures Epoxies

Cold Temperature Cure Epoxy Resins allow installation to be done at low temperatures as low as 35°F., (although it sets a lot faster at 40°F) expanding your epoxy coating and epoxy flooring installation season. Epoxy.com Cold Temperature Cure Epoxy Resins can also be used in cold storage areas like food processing areas, where the temperature cannot be raised higher than 35° F or so. Normal cured epoxy typically requires 50°F or more.

Depending on how you mix the aggregate into the products below, they can be used as a mortar for overlays, or a grout for sealing between other hardened construction materials.

Commonly Used Cold Temperature epoxies

Product #1 Cold Temperature Cure Epoxy Coating is 100% solids and specially formulated coatings for cold temperature applications. Cold Temperature Epoxy Coating #1 is able to cure at temperatures as low as 35°F. It is has Zero (0) VOCs. Since it has no VOCs, it has no solvent so it meets the strictest possible standard for a low VOC coating. It is often used in coolers and food preparation areas that require constant low temperatures. Product #1 Cold Temperature Cure Epoxy Coating is also frequently used in room temperature applications to meet super-fast cure, limited shutdown needs.

Product #10 Cold Temperature Curing Epoxy Mortar Resin – This product has a low modulus of elasticity (flexibility) and is Low Viscosity. The low viscosity allows heavy loading of the right fillers. The heavy filler loading helps not only to save money, but helps to maintain better thermal coefficient with respect to concrete and steel. The low modulus of elasticity prevents it from being brittle making it less vulnerable to thermal coefficient differences. It also gives it better impact resistance.
