Crack injection

Crack in the black brick wall

 

Many different causes can lead to cracks in concrete and brick structures. While these may not immediately weaken the structure, they do open the building to moisture, which may lead to further structural damage. To repair crack when they start, crack injection can be used. A flexible substance such as polyurethane is injected into the crack and provides waterproofing while binding the surfaces on either side of the crack.
