The most widely used method to control random cracking in concrete slabs is to place expansion joints in the concrete surface to create weakened planes where the concrete can crack in a straight line. This produces a smooth surface since the crack takes place below the finished concrete. The concrete has still cracked, which is normal, but the absence of any cracks on the surface gives the appearance of an unblemished slab. Once cracks start to appear on the surface, the area must be cleaned properly before the repair can begin. We’ll remove all loose debris, including dirt, before we power wash the crack using a jet-type spray attachment. We highly recommend pressure washing for any project area with mastic installation or sealant services. If the crack is stained with oil or grease, then we’ll clean the area with detergent before rinsing it thoroughly.
Lastly, we’ll allow the cracked area time to dry completely before proceeding with the repair. Mastic Services Mastics are materials used for gap filling, sealing, glazing, and waterproofing concrete. Commonly referred to as the waterproof expansion barrier between your pool and your deck, it’s main purpose is to allow movement between your pool and your deck without damaging the deck or your coping stones. Mastic is a special type of caulk that’s resistant to chemicals, water, and UV rays and designed for various commercial and industrial applications. We pressure wash the project area for long term adhesion, then fill it with foam backer rod and replace it down to a 1/2″ depth with sealant. Once we’re done you can rest assured that your commercial or industrial project will be protected from the elements for years to come.
Our concrete professionals only use high grade mastics, which are used in all major construction and industrial markets including the transportation industry and the automotive industry. Mastic installation usually takes between two (2) and three (3) hours depending on the size of the area being serviced combined with a cure time of twenty-four (24) to forty-eight (48) hours, depending on the temperature.
