Concrete 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.

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 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 signify foundation ground subsidence. Importantly, they can be a trip hazard, mainly if they cause water to pool in certain areas, 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, which could result in the warranty becoming void.

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.

A cost-efficient, Resin Injection solution can prevent further structural damage and potentially huge expenses.

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

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

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.

Will there be disruption?

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

Do I need to send staff home while works are being completed?

Most projects don’t require you to vacate the premises or move furniture or equipment. For the most part, you can keep operating as usual. Driveways can often be driven on in as little as 30 minutes after treatment.

Does this come with a warranty?

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