Commercial Slab Lifting & Levelling


Concrete Slab Lifting and Levelling

We inject engineered resin to improve your founding soil when you need to re-level your concrete slabs.

Teretek® is an approved foundation repair solution for insurance, council, and government standards, so you can be assured that you are getting the best possible price for the work.

Our non-invasive and cost-effective solution is a safe way of re-levelling concrete slabs with soil settlement or subsidence that could otherwise lead to more severe problems and become a safety hazard.

Teretek® resin is rapid curing, and the pavement can be returned to service within 30 minutes of the work being completed, minimising disruption to operations.

Slab Lifting

Before & After Treatment

A sunken slab can be a significant issue for operating a business.

It may result in fencing off areas, while equipment such as automated forklifts may not be able to function correctly. In the worst case, the sunken areas can become a health and safety risk for employees.

Our non-invasive and cost-effective solutions can raise, re-level and re-support concrete slabs with minimal disruption to business operations.

What causes the sinking of a concrete slab?

Sunken or unlevel slabs and hardstand surfaces in warehouses or logistics environments can be a sign of foundation ground subsidence.

There are many different causes of subsidence and various contributing factors. All involve some sort of change in the ground, which, in turn, generates movement of the soil.

Sunken or un-level slabs and hardstand surfaces in warehouses or logistics environments can be a sign of foundation ground subsidence. Importantly, they can be a trip hazard, mainly if they cause water to pool in certain areas, further increasing the risk of slips, trips and falls for your employees.

If the area is a hardstand for plant and equipment, uneven floors can result in machinery becoming un-level or misaligned.

This can create significant issues around machinery maintenance and performance; some sensitive equipment can stop functioning correctly and it could even void the warranty.

These un-level surfaces usually indicate soil subsidence underneath, which can deteriorate further and cause expensive, hard-to-fix damage to buildings and other structures. Even an un-level driveway at commercial premises left untreated for too long can become fragmented and unsalvageable.

You can prevent further structural damage and potentially huge expenses with a cost-efficient small resin injection solution.

Concrete Slab Lifting & Levelling FAQ’s
What happens with unlevel driveways, floors and hardstand areas?

After the application of the Mainmark solution, unlevel surfaces will become aligned again as the ground underneath is strengthened and re-supported. Simple cosmetic repairs may be required.

Will there be a mess?

Very little, if any. We use Teretek® engineered Resin Injection technology, which is likened to “keyhole surgery”, or JOG Computer-Controlled Grouting, with no major excavation and minimal disruption or mess. The injection holes required are very small.

How long does it take?

Each project is different and depends on the required amount of lift, area for correction, building construction, and ground conditions. Most projects can be completed in a day or two, and we can work at night or on one area at a time, so your business can keep operating.

Do i need to send my workers home?

No, most projects don’t require you to vacate the premises or even move furniture or equipment. For the most part, you can keep operating as normal. Driveways can often be driven on in as little as 30 minutes after treatment.

What warranty will i get?

The materials we use have been developed for use underground and have been specifically engineered to resist shrinkage and deterioration. Teretek® is warranted by Mainmark for an industry-leading period of 50 years.

Is it safe and environmentally friendly?

Injected Teretek® and JOG materials are environmentally inert and have no detrimental effects on the environment.
