Concrete Repair

Concrete surfaces are durable but not indestructible. Damaged joints, deteriorating cracks and surface areas in concrete floors are a major problem encountered in virtually all buildings at some stage during their service life. The problems created by floor defects are many and can come at a cost. 

Damaged concrete can reduce productivity by slowing down the vehicles used on the surface, plus causing the wheels and components excessive wear and tear. Cracks in concrete can also be a potential safety hazard, leading to dangerous falls or load tipping. Additionally, pests can seek out cracks in the surface and take shelter in them. If your concrete surface is public-facing, cracks are just plain unsightly.

Start With Better Surface Preparation

The best way to protect your concrete and ensure longevity is through better surface preparation. Concrete preparation can be time consuming but skipping this step will undoubtedly leave you with unsatisfactory results and a less durable surface.

 Prepare your concrete surface with a DiamaPro grinder for best-in-class results. Your surface will be left smooth, clean, and ready for resurfacing or repair.
