Uneven Exterior Concrete at Madison, MS Home

Challenge

A customer gave us a call after noticing that cracks were starting to form in the driveway. This driveway was extremely uneven and becoming a hazard for the  family.

Solution

We also installed the PolyLevel® system which uses high-density polyurethane expanding foam to raise settled concrete foundations and slabs. The state-of-the-art polymer injection is a fast-acting, affordable alternative to mudjacking and concrete slab replacement.

Installers use specially-designed equipment to inject structural-grade polymer into penny-sized holes bored in the slab. After the void underneath the concrete slab is filled, the expanding foam will lift and level the slab. PolyLevel® is a quick-curing solution and the polymer is waterproof and will never wash away.

Some advantages of PolyLevel® are:

• Strong but light. PolyLevel® weighs only about 4lbs. per cubic ft., compared to 120lbs. per cubic ft. for standard fill material. PolyLevel® ’s light weight makes it useful where denser fill material might impose an undesirable load on weak soils. Despite its light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than mudjacking.
• Waterproof. Once cured, PolyLevel® will not wash away. PolyLevel® ’s waterproofing properties can be beneficial in certain applications.
• Stable and inert. PolyLevel® does not react with soil or moisture; it will not leach harmful chemicals into the soil.
• Quick curing. Down time is minimized with PolyLevel® concrete repair. Full loading of the foundation, roadway or other structural elements can usually happen about 15 minutes after the material is injected.
• Adjustable. Adjusting the density and expansive force of the 2-part foam affords a wide range of geotechnical uses. Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand. An experienced applicator can factor not only the weight of the structural element but also soil characteristics and temperature and weather conditions. Special formulations are possible for applications where water must be displaced.
• Noninvasive. PolyLevel® injection equipment isn’t bulky, enabling applicators to access confined areas. When properly injected, PolyLevel® is not as messy or disruptive as other slab and foundation-lifting techniques.
