Time and temperature differentials take a toll on concrete walks and driveways. Slabs sink, heave, and tilt one way or the other. Rather than replace the entire concrete path or driveway, concrete leveling using polyurethane foam or concrete grinding in Denver are attractive alternatives. Uneven sidewalks are a trip hazard. Unfortunately, many business owners and homeowners do not realize they are opening themselves up to legal action should someone trip and fall. Concrete grinding is a practical way to eliminate trip hazards.
Tree roots can lift sidewalks, so can the loosening of soil or repetitive freeze-thaw cycles. Concrete grinding will take off up to 1 ½ inches off concrete. The process leaves a smooth aggregate finish where the trip hazard has been eliminated. The process uses a concrete grinder that sands down the raised side of a joint. Aside from eliminating a trip and fall hazard and the possible liability, concrete grinding can save money. Damaged sidewalks and driveways can be repaired instead of having to be replaced. To make the repairs correctly, professionals such as Concrete Repairs Denver should be engaged to do the work.
If the concrete has moved to such an extent that concrete grinding techniques cannot be employed, not all is lost. Concrete leveling in Denver uses polyurethane foam that is injected under the driveway or walkway. The foam is injected under pressure. As the foam increases in volume, the slab is leveled and stabilized, and voids under the slab are filled. Using expanding foam rather than employ the traditional mudjacking approach is ideal in areas where cleanliness is important. Foam injection uses smaller holes. Less dust is created during slab preparation. Injected foam concrete leveling is an ideal repair method for concrete slabs that have a decorative coating. The holes left after the process has been completed can easily be filled with matching stained concrete.
