Injected polyurethane is made from more than 40% recycled material, there is currently no other polyurethane material on the market that offers this type of carbon reduction!

Our polyurethane is manufactured by a team of environmentally friendly chemists, it is double-component polyurethane foam and specially designed for leveling and stabilizing concrete. Our patented materials are made from recycled components, making our “greenest” polyurethane foam on the market.

Stabilization of concrete slab

We use a mono-component polyurethane developed to bind and stabilize loose soils.
The amount of material needed to stabilize a region will depend on the moisture in the soil. When grout is pumped into the ground, it reacts with moisture and expands to fill voids and forms a watertight barrier.

Has your cement slab collapsed?

No problem, Samson concrete lifting has a polyurethane resin injection technology underneath the subsided cement, which allows you to lift and replace your cement.

Also called “slabjack” this system is ideal for all concrete lifting work or to fill a cavity under the concrete.


Duplicate injection

We offer the slab injection service with 2 mobile units to better lift large slabs and prevent cracking.

We have all types of equipment to meet your needs. When the work is difficult to access, we have mobile equipment that we can move near the slabs to be lifted, such as underground parking lots.

Advantages of polyurethane resin injection:

Why do I have to raise the concrete or fill a cavity?

A cavity under the concrete can cause a collapse and damage the structure or someone could be injured during a slab collapse. High-risk structures are your basement, garage, driveway or patio. A cracked bottom slab creates an uneven surface that can pose a safety risk.
