Floors under pressure
A warehouse floor carries racking, pallets, forklifts and other machinery. Over time, joints break down, the surface wears or dusts, cracks open and edges crumble. Damaged floors cause vibration for trucks, risk load instability, and create trip hazards for staff. They can also let in moisture or chemicals.
Common defects
- Joint damage where the edges spall under repeated wheel impacts
- Cracking, from shrinkage, overloading or ground movement
- Surface wear and dusting from abrasion or poor finishing
- Potholes and broken areas where the slab has been struck or has settled
- Uneven slabs where slabs have moved or curled at the edges
- Contamination damage from oils, chemicals or standing water
Repair approaches
Choice of repair depends on the cause. Non-structural shrinkage cracks may only need routing and sealing with a flexible filler. Wide or moving cracks need to be assessed to determine whether they are active. Spalled joints can be cut back and refilled with a repair mortar or resin suited to the traffic. Larger damaged areas are cut out and recast with new reinforced concrete, tied into the existing slab. Where the ground beneath has settled, void filling or slab lifting may be required, and where the slab is thin or unsuitable, a new topping or full replacement could be needed.
Minimising disruption
A working warehouse cannot always stop. Repairs can often be phased by bay, and fast-curing materials can reduce downtime. We plan the sequence with you so access and loading can continue where possible.
Linked considerations
If you plan to install racking, a mezzanine or heavier plant, the floor should be checked for capacity, see mezzanine floor installation. Spalling concrete elsewhere on your premises is dealt with under concrete spalling repairs. Newcastle and Tyneside include many industrial estates built on varied ground, including former industrial land, and ground conditions can affect slab behaviour.
Employers have duties relating to safe workplaces, covered at GOV.UK. Alterations may need Building Regulations approval, see the Planning Portal.
Frequently asked questions
Can floor repairs be done while the warehouse is operating?
Often in phases, working bay by bay with fast-curing materials. We agree access, hours and protection with you beforehand.
How do I know if a crack is serious?
Wide, growing, or stepped cracks, or those with level differences either side, should be checked. Fine shrinkage cracks are usually minor, but an inspection confirms which type you have.
