Concrete slab re-levelling services

Mainmark provides bespoke solutions for concrete slab lifting, concrete slab jacking and concrete slab re-levelling, addressing the underlying subsidence problem by strengthening the ground beneath. Our level correction methods can cater to any building size, from smaller warehouses to multi-use transport hubs. Unlike more traditional methods such as underpinning or piling, our slab lifting technologies are non-invasive, cost-effective, time-efficient and cause minimal disruption to the business and operations.

Sunken or unlevel slabs and hardstand surfaces in warehouses or logistics environments can signify foundation ground subsidence. They can also be a safety hazard, particularly if they cause water to pool in certain areas, increasing the risk of slips and falls.

If the area is a hardstand for plant and equipment, uneven floors may 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 a machine’s warranty.

Why concrete slab lifting services are necessary: What causes 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 may start to subside.

There are many different causes of sinking slabs, including:

Extreme weather conditions that cause reactive clay soil to contract or expand.
High-trafficked areas where excess weight and movement can loosen sandy or fine-particle soil.
Ponding slabs, where excess water gathers on the surface.
Nearby excavations that cause the ground to vibrate.
Soil being compacted during 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 crosses the slab. If left untreated, the lack of support under the panel can cause slab cracking and uneven surfaces.

How Mainmark’s concrete slab lifting contractors can help

The best way to fix sinking concrete floors or slabs is to raise and re-level the foundations to re-support the building or structure. Mainmark specialises in concrete slab lifting services and concrete floor re-levelling using non-invasive, cost-effective and time-efficient techniques, giving sunken access roads, concrete slab flooring, hardstand areas and yard pavements a new lease of life.

Using our proprietary products, our concrete floor re-levelling contractors can achieve both ground improvement and re-levelling of concrete slabs, lifting concrete slabs back to level – in most cases, within a day.

Mainmark – concrete floor re-levelling contractors:

– we use non-invasive techniques, likened to keyhole surgery. We don’t tear up floors or excavate soil. Injection holes can be as small as 6mm.

– we are fast, we can complete small- and large-scale projects in a fraction of the time that traditional methods would take.

– we improve structures for the future, our methods strengthen weak ground, so buildings generally become level, crack-free and more stable.

– we don’t make a mess,there is generally no dust, water or anything else to clean up.

– we don’t cause further damage. We fix existing damage. Wall and floor cracks generally close, doors and windows can usually operate properly again, and trip hazards are eliminated.
