Polyurethane foam has become an increasingly popular choice for concrete crack repair in recent years. This is due, in part, to the many benefits that it offers.
So, what is polyurethane foam? Polyurethane foam is a type of insulation made from two liquids that are mixed together and then foamed up using air or nitrogen. It is available in both open cell and closed cell varieties, with the latter being more common.
Open cell foam is less dense and more permeable than closed cell foam. This makes it a better choice for applications where moisture needs to be allowed to escape, such as roofing and insulation. Closed cell foam, on the other hand, is more dense and water-resistant. It is thus a better choice for structural applications, such as concrete crack repair.
Polyurethane foam comes in several different strengths and densities. The lowest density types are typically used for insulation purposes, while higher density types are more suitable for the structural repair of things like cracks. Concrete crack repair with polyurethane foam typically involves filling the crack with an expanding spray product that becomes up to ten times stronger than the surrounding concrete within minutes after application.
What are Some of the Benefits?
A few of the major benefits of using polyurethane foam concrete crack repair needs include:
(1) It is very easy to apply;
(2) Provides long-lasting results;
(3) Requires no curing time;
(4) can be used to prevent water damage, which is particularly beneficial for basements and crawl spaces where concrete cracks are often common;
(5) after the foam cures it becomes inert, meaning that it does not support mold growth.
As you can see, polyurethane foam is an extremely versatile product with many applications as a concrete crack repair material.
