POLYLIFT CONCRETE LEVELING
When the soil underneath a concrete slab is of poor quality and can no longer support its weight, the slab will sink or settle. If some areas of soil are weak and others are not, the result may be uneven, unleveled, cracked, or caving concrete. Sinking concrete is caused by excessive weight, expansion and contraction due to changes in the weather, and erosion of supporting soil due to the movement of water below the surface.
COMMON AREAS THAT EXPERIENCE SINKING
- Garage floors
- Pool decks
- Basement slabs
Sinking concrete is unattractive and can create tripping hazards if not repaired. Epp Concrete offers concrete leveling services as a solution to sinking concrete issues. In most cases, the price of raising your concrete is just a fraction of the cost of completely replacing it.
MUDJACKING VS POLYINJECTION
Mudjacking is a technique in which a mixture of water, soil, concrete, and other materials are hydraulically pumped under sunken concrete to fill voids and lift the concrete upwards. It involves drilling several holes into a slab of concrete so the material can be pumped below the slab, and then the holes are filled with concrete to mask the repair.
Polyinjection is a new concrete leveling technique that combines the functionality of mudjacking with modern technology. Polyinjection uses a foam material that is injected underneath a sunken slab of concrete. A reaction occurs within the foam that causes it to expand and harden, thus lifting the slab and filling any voids. The foam material is 100% waterproof, will never break down, and perfectly shapes to the voids beneath concrete to completely support the slab. Foam is much more lightweight than the traditional mud, so it does not overburden weakened soil. Additionally, polyinjection tends to look better and last much longer than traditional mudjacking.
Both mudjacking and polyinjection require special equipment and should only be performed by professionals. If you notice uneven or cracked concrete surfaces in or around your home, allow the experts at Epp to inspect the problem and give you a quote.
