Concrete Floor & Slab Crack Repair

Since 1998 Applied Technologies has been manufacturing quality waterproofing and repair products for professionals and homeowners. Our polyurea injection material can be used to repair cracks in concrete slabs, concrete floors, pools, decks, sidewalks and driveways.

Concrete slabs and floors can develop cracks for a variety of reasons. One of the most common reasons is a shrinkage crack. Water is one of the key components of concrete. As the concrete cures, the water is eliminated. This reduces the volume of the concrete, it shrinks in size. The shrinkage causes stress to develop in the concrete and this stress must relieve itself. So the concrete cracks. This is a normal condition, especially in residential basement floors.

Another reason that concrete cracks is from the substrate under the concrete heaving. When this happens, the concrete is broken and it cracks. Usually, the concrete slab on one side of the crack is elevated a little compared to the other side.

Finally, it is possible for a settlement crack to occur. This is the opposite of a heaving crack. The soil under a concrete slab or concrete floor is not properly prepared prior to the concrete placement. Eventually, the area under the slab settles and is no longer in contact and supporting the concrete slab. The concrete slab then gives way and cracks.

Why Use a Polyurea Injection Material?

Most repair methods for fixing a concrete floor crack are little more than band-aids.  Putting an epoxy, cementitious or caulk product over the top of a concrete floor or slab crack is not enough.  Soon the the crack with transmit itself through these repair methods and reopen.

Injection is the key.  Injection completely fills the crack from top to bottom.  The polyurea tightly bonds to the concrete and has a tensile strength of 4000 psi.  Polyureas are an extremely fast setting material that cure in 10-15 minutes.  When they are mixed with sand aggragate it is possible to get a look that nearly matches concrete.
