Commercial and Industrial Slab Lifting
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.
How Mainmark has helped commercial and industrial services to rise and re-level concrete slabs:

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.
For example, droughts dry the ground, resulting in the soil (especially clay) contracting. Excavation and construction, even heavy traffic, and machinery vibration can move, displace, and alter the condition of the ground.
In extreme cases, seismic activity shakes the ground, often resulting in liquefaction which ‘squeezes’ liquid up from the ground resulting in differential settlement.

Sunken or unlevel slabs
Sunken or unlevel slabs and hardstand surfaces in warehouses or logistics environments can be a sign of foundation ground subsidence.
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 machinery maintenance and performance; some sensitive equipment can stop functioning correctly and it could even void the warranty.
These unlevel surfaces usually indicate soil subsidence underneath, which can deteriorate further and cause expensive, hard-to-fix damage to buildings and other structures. Even an unlevel 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.
