Are your floors sinking? When this happens, it reduces the carrying capacity and limits the designed use of a slab, whether it be traversing with heavy machinery, heavy equipment or heavy storage for logistical and commercial warehouses. Sinking floors can not only cause significant structural problems but also downtime for homes and businesses.
What causes sinking floors?
Sinking floors and uneven floors are usually caused by voidage that then leads to subsidence. This means that the ground beneath your flooring may be moving in response to a variety of factors such as un-compacted fill, voidage from compromised plumbing services, such as storm water, sewer, or leaking water mains. This will result in the moisture content of the soils changing: in reactive clays, this will result in the ground expanding and contracting forming voids; and in sandy loams and sands, these factors will contribute to washouts, again compromising the load bearing on the slabs. Other factors affecting the ground are poor drainage and poor site design that compromise the bearing capacity of the ground. Extreme weather factors can also impact on structures.
What are the signs of a sinking floor?
If you worried about sinking floors caused by subsidence or voidage, there are signs:
- Cracks in your external and/or internal walls and ceilings
- Cracks in external and/or internal concrete slabs, cement, steps or floors
- Doors that are jamming against the floor or frame when you close them
- Areas in your floor that slump or sound “hollow”
- Variation of your “skirting boards” where the slab is lower than originally intended
Subsidence and voidage can represent a serious structural problem to the integrity of your home, business or worksite and a potential hazard to you and those around you. This can cause Work Health Safety issues relating to injuries sustained by forklift operators from traversing uneven slabs, not to mention the maintenance costs of the actual forklift.
