Intech Anchoring Urethane Injection System

Urethane injection, also known as polyurethane or grout, is the most common way to seal and fill a crack in concrete and foundations. The popularity of urethane injection as a solution is due to its flexibility and versatility for a variety of applications. These include commercial and residential foundation or concrete crack repair.

#900 Intech Anchoring Hydro Sealant

#900 is a single-component hydrophilic polyurethane chemical grout. It quickly expands when it comes in contact with water. This expansion forms a sturdy, flexible closed cell foam that bonds very well to concrete. When cured it becomes an extremely tough and flexible barrier against water penetration.

Benefits of Using Urethane Injection Crack Repair

There are many choices in concrete foundation crack repair systems, but not every crack should be treated with the same solution. For situations that are not right for urethane injections, we also offer concrete repair epoxy. Simply because there’s a crack in a home’s foundation does not mean that it is letting in moisture. However, even hairline cracks have the potential to allow water leaks into the house.

A significant benefit of using urethane injections is that it can be applied to damp surfaces. This feature eliminates the need to wait for the surface around the crack to dry. Like all foundation crack repairs endorsed by Intech Anchoring, the urethane will prevent water from entering the interior of the basement.

The urethane injection fits into a variety of situations. It is available in three levels of viscosity to suit any situation and surface—indoors or outdoors.

An additional advantage of urethane injection for concrete repair contractors is the product’s flexibility. Allowing for slight movement or shifting of the foundation protects your investment and prevents further damage.
