Epoxy & Urethane Injections

The point of carrying out epoxy and urethane injections on a building is to create a flexible seal in those areas where masonry has cracked, and is vulnerable to further damage from water and the elements. For instance, if you manage an apartment building and there’s a crack in the foundation wall, it may be necessary to inject epoxy or urethane into the crack so as to prevent further water damage, and to prevent water from penetrating the foundation and seeping in to the interior.

In cases like this, it isn’t really feasible to replace an entire wall or a footing, so the simplest solution is generally to inject some kind of sealant into the structure from the inside – and that will prevent leakage from the outside. This is one of the most effective solutions available when you have some kind of crack or leakage in a basement wall or in the foundation. Whenever you spot an issue like this, you should contact us at Ev-Air-Tight, Shoemaker, Inc., and let one our knowledgeable technicians investigate the problem, so you can be aware of the full extent of the issue.

Epoxy Urethane Injections

Fixing Cracks in Foundations & Concrete Walls

The first step necessary in repairing your foundation wall will be to attach plastic injection ports along the entire length of the visible crack. After that, a surface sealant like epoxy will be applied, so that the injected material stays in place, and to help heal the crack. Then the crack is filled with injected material which will either be epoxy or urethane, and then it’s just a matter of letting the repair work cure in place. In years past, epoxy would have been used exclusively as the crack sealant, but in recent years, urethane has become more popular, because of the advantages it provides.

Urethane has grown to be more popular recently because it is much less rigid than epoxy, and that means it can adapt to its environment more readily, and fill the gap which has been created. It actually forms an impenetrable gasket in the wall or foundation, all the way through the crack to the exterior. Because urethane is so flexible, it actually ‘breathes’ with the building whenever there is any movement. So, instead of cracking when there is any kind of foundation movement, the urethane will simply move in unison with the building, and maintain full contact with the concrete.
