    Almost all Epoxy.com epoxy resins can be used as an epoxy bonding and 
    adhesive systems.  However, the thicker epoxies (epoxy gels) typically
    make the better adhesives, because they are easier to use when Appling a
    thick layer.  Below is a list of medium to very thick epoxies.  These
    epoxies are designed with the primary function of bonding various
    materials to other materials. Epoxy.com Gel Adhesives Systems are called
    by a number of different terms throughout the industry, including but
    not limited to: Epoxy Bonder, Epoxy Adhesive Systems, Epoxy Gel Adhesive
    Systems, Epoxy Bonding Systems, Epoxy Gel Patching Adhesive, etc.

  • Waterproofing

    – Most Epoxy.com Products are waterproof by nature.  The products
    you find here are the work-horses of
    waterproofing.
  • Coating Systems
    Here are listing of Epoxy.com epoxy coatings and urethane coatings. The
    Epoxy.com Products listed below are either pigmented or available in
    pigmented. 
  • Chips Flooring – The use of color chips can
    change all that! Color chips are increasingly being used in combination
    with “wet” products such as Epoxy.com
    Product #315 Seamless Polymeric Multi-Colored Flake Chip Flooring
    Resurfacing System
    to create decorative seamless flooring with more to offer than other ornamental
    products…Quality! Due to their easy application, these products can be
    used by both professionals and skilled do-it-yourself enthusiasts.
  • Primers
    and Sealers
    – Epoxy.com has a wide variety of primer and sealers
    listed here is a listing of the most
    popular ones.
  • Seamless Flooring
    – Epoxy.com Products that were specifically designed for seamless
    flooring systems.  Epoxy.com 100% Solids Epoxy Coatings and
    Flooring resins can be used in conjunction with broadcast aggregates and
    trowel down aggregates to create a highly durable seamless epoxy
    flooring systems.

How to Epoxy inject Very Large Cracks – How Large a Crack can be Epoxy Injected

April 22, 2010

What is the Largest Crack that can be Repaired with Epoxy Injection

A reader writes:“What is the largest concrete crack that can be injected with an Epoxy Injection repair?”

For concrete outdoors and/or is going to see extreme temperatures, you
would typically want to limit your injection to about 1/4 inch.  If the
crack is larger than that you may experience some thermal coefficient issues, if
injected using normal epoxy concrete injection techniques. 
Thermal coefficient is the rate that materials expand and contract due to
temperature changes. Neat epoxy resin expands at a rate greater than
concrete. In small cracks this is not important, but as the mass of epoxy
gets greater, the potential for differential movement gets greater.When I have been forced to epoxy inject these cracks larger than 1/4 inch
I like to use Epoxy.com Product #301 – www.epoxy.com/301.htm.. 
Epoxy.com Product #301  is is a low mod (more “flexible”) injection
material and is less likely to create a thermal co-efficient problem than a
high modulus material.

If the crack is still bigger, I try to pack as much Epoxy.com Product
#703 – www.epoxy.com/703.htm
Low-Mod Epoxy Gel Adhesive as I can into the crack.  First I place
copper tubing as far back into the crack as I can.  Then I fill out to
the surface with the Epoxy.com Product #703.  If the crack is large
enough you can also mix up to 1 part silica sand with 1 part of mixed
Epoxy.com Product #703.  Mixing in the silica sand saves material
costs, and makes the Epoxy.com Product #703 easier to trowel. Most
importantly the thermal coefficient of the Epoxy.com Product #703 and silica
sand is much closer to that of concrete than the Epoxy.com Product # 703 alone.

After the Epoxy.com Product #703 has hardened, you can pump the Epoxy.com
Product #301 into the copper tubes that were inserted earlier.  This
results in a very effect, well designed and engineer solution for larger
cracks. When in doubt how to proceed with larger cracks, please contact me

Epoxy Injection – Minimum Crack Size

April 19, 2010

How Small a Crack in Concrete Can Be Epoxy Injected?

Norm:
Typically a crack that is 30 or 35 mils or larger (about 1/32 inch) can be epoxy injected. You can get into even smaller cracks under the right conditions with Epoxy.com Product #308 Ultra Low Viscosity Injection Resin for Load Bearing Applications an Ultra-Low Visocosity Epoxy Resin System for use as epoxy injection or low viscosity epoxy mortar resin. It is 100% solids and is mixed 2:1 by volume. Meets or exceeds the requirements for ASTM C881 Types I and IV, Grade 1, Classes B &C.

One of the most versatile, problem solving products available in epoxy systems today is Epoxy Injection Resin. Structural 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 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.

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.

Crack Analysis

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. 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 # 485 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. more…
