Name: Solid Ground. Descripton:Solid Ground offers the most professional, state-of-the-art concrete lifting and leveling for less then half the cost of replacement. Solid Ground levels and lifts your concrete cracks with polyurethane. Here are just four, of the many reasons why Solid Ground only uses Polyurethane?1. Polyurethane is hydrophobic, in other words polyurethane is 100% water proof. Yes not merely water resistant, but truly water proof. The pressurized hot injected liquified polyurethane, will displace moisture and while at the same time, seek out voids and stabilize your concrete.2. Polyurethane has a rapid cure rate. This allows Solid Ground to have your concrete cracks job completed quickly. With in minutes, after completion, your patio, garage, driveway or factory floor is ready to use.3. Polyurethane is injected through 5/8 inch hole. We will drill dime sizes holes that are easily patched and blend in perfectly.4. Polyurethane is 100% green. Solid Ground and you are part of the renewable recycling answer.We guarantee that when we have lifted a slab of concrete with concrete cracks it will not sink or settle for at least three years or much longer. The liquified hot polyurethane finds the problem area and fills it. If for some reason, it does subside, we will come back and lift it again.Slab jacking or mud jacking can not offer guarantees. Why? Because they have left behind mounds of grout slurry. This grout is not water proof, it is extremely heavy and it has not filled the void, it is merely balancing your patio, driveway or garage floor on its peak. You now have introduced underneath your concrete, stress raisers that are waiting to fail.Solid Ground can offer this guarantee because we use only polyurethane. It’s the only material with a very, very low risk of resettling. With other concrete materials, you may be lifting your concrete again in another year or two. Rating of 5.0000 based on 1 reviews.
