Urethane and Polyurethane Crack Injections

Urethane and polyurethane materials are effectively used for concrete crack injection repairs as well as basement leak repairs.

Waterproofing companies inject these materials into concrete foundations all the time as it is an effective and long-lasting solution that can be done quickly at a low cost.

The compacted soil outside a house’s foundation exerts a great deal of force against the foundation walls. This pressure is usually responsible for causing cracks in the foundation. And when the soil becomes saturated, the water then seeps through the wall cracks into the home.

Urethane Crack Injection:

Urethane is an expanding, flexible sealant that uses water to form an impassable or dense seal to fill a crack all the way through to the outside.

How does the Urethane Injection work?

The waterproofing contractor will first attach plastic injection ports to the crack at intervals along the length. The urethane sealant is then injected into the ports along the crack. This will expand and fill its way all through to the outside soil. This stops the flow of water from the outside. A surface sealer is then applied over the crack to hold the injected sealant inside the crack until it cures.

Urethane vs Epoxy

Waterproofing contractors in the past have used Epoxy as a sealant to repair cracks. However, the main disadvantage to this is that epoxy is rigid and not flexible to shifting or foundation settlement. As a result, movement will cause further cracks and water leaks. Also, as epoxy does not adhere at wet concrete, contractors must wait until the surfaces are dry before attempting to repair any crack. This will of course, not be convenient to the home owner.

Urethane on the other hand, retains contact with the concrete and moves with the wall. The urethane sealant also makes use of the surrounding soil as a compact barrier to help create a firm repair.

Polyurethane Injection

Designed for concrete repair, polyurethane injection sealers are the perfect tool.  They are highly popular today because of their flexibility and durability. When injected the sealant expands upon contact and fills the crack completely.  While the foundation continues to shift, the polyurethane remains flexible and ensures that there is no future water leakage.

Working from inside your basement is the best way to repair concrete foundation cracks.  Holes are drilled along the crack through the soil and the polyurethane sealer is then injected. Unlike other surface repairs, the injected polymers are not weakened due to weather, traffic, or ultraviolet rays.

Most importantly, polyurethane injection will prevent expensive repairs and problems in the future. Potential damage done by water leaks to the finished basement or cost of repairing concrete walls caused by corrosion show the clear advantages of permanent crack repair.

Repairing cracks is of the utmost importance. If a crack leaks once then more than likely it will leak again after every rainfall. Crack repair will save you time, money, headaches from dealing with a leaky basement and prevent mold and mildew problems in your home.
