Why is slab lifting in commercial buildings required?

Sunken or unlevel slabs and hardstand surfaces in warehouses or logistics environments can be a sign of foundation ground subsidence.
Sunken or uneven concrete slabs can be a trip hazard. They can also cause water to pool in certain areas, further increasing the risk of slips and falls for staff and the public.
If the area is a hardstand for plant and equipment, uneven floors can result in machinery becoming unlevel or misaligned. This can create significant issues around machine maintenance and performance; some sensitive machines can start producing faulty outputs, and it could even void the machine’s warranty.
What causes concrete slabs to sink?

Over time, as the ground beneath slabs compresses or expands due to changes in ground moisture levels, the weighted concrete slab above will start to subside at different points.
There are many different causes of sinking slabs, including:
Extreme weather conditions that cause reactive clay soil to contract or expand
Highly trafficked areas where excess weight and movement loosen sandy or fine particle soil
Ponding slabs where excess water was used to cure concrete in small areas
Nearby excavations that cause the ground to vibrate
Poorly compacted soil during the construction of the building
Incomplete or inadequate foundations or footings
Common indicators of an unlevel slab are misaligned joints between slab panels and soil being pushed out as weight presses down on the slab. Left untreated, the lack of support under the panel can cause slab cracking and uneven surfaces.
Slab lifting with minimal disruption

Mainmark’s modern slab lifting and re-levelling technologies are reliable, quick and cost-effective. Our methods are flexible, minimise disruption on site and can be scheduled around other trades. Work can also be completed much faster than with traditional methods of slab lifting.
Our non-invasive slab lifting technologies allow building occupants and contents, including plant and machinery, to remain in place. Most of the time, the facility can remain operational.
Treated roads, driveways, airport runways and concrete slabs are trafficable immediately.

Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.

Teretek® – Resin injection underpinning alternative
Teretek® is an engineered solution for re-levelling subsided buildings that utilises a plural component, expanding polyurethane resin. The expansion force of the material results in the controlled lift of structures, with a by-product of localised bearing capacity improvement through soil densification.

JOG computer-controlled grouting underpinning alternative
JOG computer-controlled grouting uses a multi-point injection technique to insert cementitious grout materials under foundations. It can be used under commercial and residential buildings ranging from single-storey shops to high-rise structures. The injected materials have a controlled set time, which allows for the precise lifting of a structure.
