CHEMICAL INJECTION

Slab Jack Industries advanced structural polyurethane solutions are designed to meet the diverse needs of our valued residential, commercial, and civil/industrial clients. Our cutting-edge methodologies cater to these sectors ensuring excellence across various applications. We can help with the following chemical injection systems.

Structural Polyurethane Lifting Foam

High-density foam engineered for versatility and precision for lifting heavy slabs and foundations

Our precise lifting process, achieved through incremental injections, ensures unparalleled control. The foam’s rapid expansion within 10-15 seconds ensures controlled lifting, enabling precise monitoring to prevent over-raising of slabs, making it an ideal solution for a range of applications.

Stabilisation Polyurethane

Optimised for extended reach and stability

For those seeking superior performance, our stabilisation polyurethane stands out. Engineered with a slower reaction time, it maximizes reach and stability. Ideal for undersealing and stabilising joints on rocking slabs, this polyurethane is engineered to provide comprehensive support.

Permeation Grouting

Solidifying foundations with precision

Our permeation grouting technique delivers precision by saturating resin into the ground, making it suitable for diverse foundations. This method creates solid columns amid unstable ground/loose soils, providing essential support to slabs, preventing settlement. OR offering paramount support to your structures.

APPLICATIONS:

Stabilise: Peat Moss, Loose Sands/Soil

Support: New Slabs, Foundations, Helical Piers

Erosion Control: Sea Walls, Sand Bunkers, Retaining Walls

Curtain Grouting Polymers

Hydro-Insensitive Polyurethane for Varied Environments

Our hydro-insensitive polyurethane foams are made for versatility, addressing scenarios where water or moisture is present. Designed to set up and maintain dimensional stability in wet conditions, it effectively displaces water, fills voids and cracks, regenerating a watertight barrier.

We Do Not Use Toxic Chemicals: 

Major toxic chemicals, often associated with some types of polyurethanes, such as some blowing agents, formaldehyde, benzene, and toluene are NOT used in our foams, ensuring safety across residential, commercial, and civil/industrial projects.

As Safe As The Cushions You Sit On: 

The foam we install underground is like the foam in your mattress and/or in your couch. Instead of it being built in a factory, we make the foam directly under the slab. Instead of being light and fluffy, ours is intentionally engineered to be firm and strong, ensuring enduring support for your structures.

EPA Approved: 

Our cured polyurethane is certified safe by the Environmental Protection Agency, which states that cured polyurethane is safe unless burned or ground into a fine dust.

ELITE SUSTAINABILITY

In our commitment to setting new standards, Slab Jack Industries stands as the only company in Australia employing/using polyurethane foam from recycled materials, making it the “greenest” polyurethane on the market.

HMI has developed this revolutionary foam that is setting new standards in polyurethane foam quality. ASTM tested, this revolutionary foam, formulated with recycled components offers a unique advantage – supercharged raw materials that have already proven their quality. HMI’s foam offers advantages like fast tact-free time and high compressive strength, making it suitable for residential, commercial, or civil/infrastructure projects.

POLYURETHANE UNDERPINNING VS CONCRETE UNDERPINNING

ZERO EXCAVATION

Streamlined processes without excavation, suitable for any project scale.

SOIL DENSIFICATION

Strengthens and stabilises soils universally, offering a solid foundation for structures.

WATER DISPLACEMENT

Efficient water displacement, preventing infiltration applicable to various structures.

LONG-TERM RESILIENCE

Unmatched strength restoration exceeding 10 years, ensuring lasting results.

ENVIRONMENTAL CONSIDERATION

Environmentally friendly, inert, and safe, aligning with modern sustainability standards.

THE PROCESS

Step 1

Our expert applicators drill 16mm holes in the affected area, most times we can access the area from the outside.

step-1-chemical-underpinning

Step 2

Polyurethane resin is injected to fill voids underneath the slab or footings. The polyurethane expands exerting pressure to support the area underneath the slab.

step-2-chemical-underpinning

Step 3

The expansion is carefully monitored by laser level and the polyurethane is set in 15 minutes.

step-3-chemical-underpinning

Step 4

You can see the results instantly as cracks disappear and slabs lift as the polyurethane expands. Upon completion the area is trafficable and ready for use.
