Emecole Concrete Crack Repair Discovery Saves Contractors Time and Money
Two-component system avoids expensive, wasteful use of epoxy
Romeoville, IL (PRWEB) May 9, 2009 -- Basement contractors agree that in some cases concrete crack repair can be an expensive, frustrating process. Large structural cracks gobble up more injection resin than expected, while new cracks suddenly appear near the glue line. Customers complain and profits shrink. But not when Emecole's cost-saving, two-component polyurethane foam injection system is put to work.
Emecole 120 is a new, innovative solution for the ongoing problem of basement crack repair. By using a rigid, structural polyurethane foam in conjunction with carbon fiber staples, contractors save time, money and control all possible movements in structural cracks larger than 3/16th of an inch.
President Lou Cole says foundation crack repair for large problems usually involves an epoxy product. Epoxy is rigid and strong. It can weld the crack and stabilize the surrounding concrete. But wide cracks tend to leak injection resin into voids that may exist between the exterior surface of the wall and compacted soil. Since a typical 3/16th inch crack is 8 inches deep and 8 feet long, at least a gallon of epoxy -- sometimes more -- may be needed. Emecole 120 dramatically improves on that method.
"The alternative for structural cracks is to use a rigid, structural polyurethane foam as the injection resin in place of the epoxy injection resin. But with carbon fiber staples, now you have the best of all worlds - a powerful combination of injection material with foaming characteristics, coupled with staples. The staples are not cheap, but they are far less expensive than trying to fill cracks with gallons of epoxy."
Emecole 120 expands up to 6 times its initial volume to fill voids and crack within minutes, with or without the presence of water in the crack. Cole says contractors will likely only need one tube set (22 ounces) of rigid polyurethane foam, whereas the same job would require a minimum of one gallon (6 tube sets) of epoxy.
When doing concrete crack repair, Cole reminds contractors that not just any polyurethane foam will fix structural problems. A flexible, non-structural foam moves with the crack as it shifts. This is fine for basement crack repair situations that only involve leaks. But a structural, rigid foam is essential when foundation crack repair involves structural damage.
Also, contractors should avoid using a foam that can compress as a crack tries to close. This allows cracks to close. If a crack closes when it is repaired with carbon staples, the staple could pop off. By combining rigid foam injection with carbon staples, Emecole 120 arrests all movement of the crack and strengthens the area surrounding the damage.
"It's a different approach which we think is very promising. It makes an expensive cure less expensive and stronger," says Cole.
Problem solving is another advantage of using the Emecole system when engaging in basement crack repair. For example, an epoxy is a structural cure, but only at the glue line. If after epoxy is installed, a structural problem still exists, the new weakest point in the concrete is adjacent to the crack just repaired. If a new crack close to the original crack appears, a customer may complain.
Emecole 120 helps contractors avoid complaints because when using staples, the next weakest point is naturally 6-24 inches away from the original crack. If more cracking occurs, it will reveal a larger structural problem, not a contractor failure.
Emecole has been the trusted manufacturer of concrete crack repair products for more than 20 years. Since then, Emecole has evolved into a full provider of products and solutions for basement pre-finishing, waterproofing, concrete repair and crawl space sealing and insulation. Its concrete crack injection systems and patented tools have been tested, developed and manufactured since 1987.
