Slab Jacking: Expert Concrete Lifting & Stabilisation with Polyurethane Resin Injection

Is the speed and performance of your Materials Handling Equipment (MHE) affected by uneven floors inside the warehouse? Our slab jacking and concrete lifting services are a cost-effective solution.

When concrete ground slabs are unlevel or move differentially under traffic, this indicates a loss of load transfer across the joints and the potential of voiding or lack of support underneath the slab.

On internal warehouse floors trafficked by MHE, this rocking motion and uneven floor surface can cause damage to the concrete joint arris.

Unlevel floors ultimately lead to damaged MHE and increased risk of trips and falls for site pedestrians.

Minimise Hardstand Damage and Avoid Structural Failure

On external hardstands with inadequate maintenance, water ingress will further exacerbate these issues.

Heavy truck traffic can cause a pumping action when they travel over the rocking joints, and water under the slabs pumps out fine particles in the sub-base.

If not treated properly and addressed early on, these common issues only worsen over time …

… and can ultimately lead to structural failure of the floor and the need for full concrete replacements.

Introducing Slab Jacking Using Polyurethane Resin Injection

Slab Jacking via Polyurethane Resin Injection is a highly effective solution –

for stabilising and releveling concrete ground slabs suffering from differential movement and settlement.

In comparison to alternative methods such as mud jacking and concrete strip replacement, slab jacking is not only more efficient and cost-effective but is also much less disruptive.

This is critical for minimising downtime in busy industrial environments.

How Does Slab Jacking Work?

Slab Jacking, also known by many other terms such as concrete leveling, concrete lifting, foundation lifting, foundation repair, sunken concrete repair, or foam jacking, works in the following way:

Let us handle your uneven concrete issues with our professional leveling services, delivering impressive results in no time.

Our fast and effective leveling solutions are designed to eliminate trip hazards and improve aesthetics.

How We Relevel Your Floors and Hardstands

Grinding for AMR Robotics

  1. Firstly, we take level readings to determine the amount of concrete lifting required.
  2. A service location scan is then carried out to safely determine underground utilities.
  3. Holes are drilled through the full depth of the slab, in pre-determined locations at typically 600-1200mm centres.
  4. Injection ports are installed into holes for shallow injection or drive rods into the ground for deep injection.
  5. The resin is heated to the required temperatures and appropriate injection pressures are set.
  6. Selected resins are injected into the sub-base, filling voids and consolidating soil as it expands.
  7. The process is carefully monitored via a laser-level.
  8. Once the required results are achieved, the injection ports are removed.
  9. Any holes are patched with cementitious mortar.
  10. A completion level survey is taken, and the site is then returned to full service.

Benefits of Slab Jacking
