Edmonton Concrete Repair | concrete lifting & leveling
Edmonton Concrete Repair | Polyurethane foam is used for unstable concrete that is shifting and beginning to show signs of failure and breakage caused by water permeation along the traverse and longitudinal joints or water is penetrating beneath concrete and washing out sub-base causing voids and lack of support to concrete roadways, sidewalks, or driveways. Polyurethane foam is used to lift and level out the concrete. Polyurethane foam is also used for concrete void filling and slab/joint stabilizing. The process is quick allowing for minimal lane closures and disruptions. The foam can be used to lift building structures, oil or densifying and solidifying weak and compromised base soils. The polyurethane foam will never lose density and will not sink due to its lightweight material. Polyurethane foam can be used to lift or level commercial or residential projects.
Edmonton Concrete Repair | ProLift Process
1. First, a series of 5/8″ holes are drilled in an off-set pattern.
2. A two-part resin-based specialized poly-urethane foam is injected into each drilled hole leaving time for the foam to expand, making sure to fill all voids until the concrete is then lifted back to original height.
3. Once the concrete is preserved, existing voids are perfectly filled and the concrete panel is completely supported and undersealed. The solid, dense polyurethane foam material is unaffected by water eliminating future water issues after work is performed and is complete concrete may be used immediately. The holes are then filled with high-density cement grout and finished to match the existing concrete.
Edmonton Concrete Repair | Common Causes of Settlement
Dehydrated Soil Beneath A Slab
Poorly Compacted subgrade
Soil Washout — Plumbing Leaks
Water erosion (drains, sub pumps, etc)
Animals and pests
Very low viscosity.
Water impermeable polyurethane foam
Cures as fast as 15 seconds.
Small 5/8′ holes, versus traditional 2 and 1/2″ mud jacking holes
Light weight foam, over most other materials that are heavy and water based and can shrink over time.
Poly-urethane foam is strong, supporting over 50,000 pounds per square foot
Much more cost effective than a complete concrete replacement
Poly-urethane cures quickly, allowing you to walk on the surface within seconds
Unlike other products, poly-urethane will not break down over time
Most void fills take up to an hour with PROLIFT
