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, particularly if they cause water to pool in certain areas, further increasing the risk of slips 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 machine maintenance and performance; some sensitive machines can start producing faulty outputs and it could even void the machine’s 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 a commercial premises left untreated for too long, can become fragmented and unsalvageable.
It’s essential to fix these problems as soon as possible to prevent further damage and potential hazards.
What causes slabs to sink?
Overtime, as the ground beneath slabs compresses or expends 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, high trafficked areas where excess weight and movement loosens sandy or fine particle soil beneath, ponding slab 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 and incomplete or inadequate foundations or footings.
Common indicators of an un-level slab are misaligned joints between slab panels and soil being pushed out as weight crosses across the slab. If left untreated the lack of support under the panel can cause slab cracking and uneven surfaces.
