Concrete Lifting and Leveling
Polyurethane injection or PolyLevel™
Sometimes, the combined weight of concrete and what it supports causes concrete settlement to occur. The soil beneath the concrete compresses and can cause major problems. PolyLevel permanently lifts and stabilizes sinking concrete slabs with a high-density polyurethane formula. Small holes are drilled into the concrete slab and polylevel is injected underneath. The expansion of the polyurethane allows for accurate concrete lifting and leveling.
PolyLevel® offers important ADVANTAGES
- 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 lifting and leveling. Full loading of the foundation, roadway or other structural element 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.
