Concrete Slab Replacement & Shell Upgrade
A detached outbuilding had a crumbling concrete floor slab with significant damp ingress. The client wanted to convert the space into a usable workshop and storage area. We carried out a complete slab replacement with modern damp proofing, insulation and structural repairs to the shell.
Scope of Works
- Break-out and removal of existing failed slab
- Excavation and preparation of sub-base
- Installation of damp-proof membrane
- New reinforced concrete slab
- Structural repairs to walls (repointing and patching)
- New lintel above doorway
- Roof inspection and minor repairs
- Electrical installation (lighting and power)
Challenges & Solutions
The existing slab had no damp-proof membrane and was laid directly onto earth.
We excavated to a suitable depth, laid compacted hardcore, installed a heavy-duty DPM lapped up the walls and poured a new reinforced concrete slab, eliminating damp ingress completely.
Access was limited through a narrow side passage with no vehicle access.
We organised materials delivery and waste removal using wheelbarrows and a mini dumper. Concrete was pumped in through a flexible hose from the road. It required more labour but kept the project on schedule.
The Result
The outbuilding was brought back to a solid, dry and usable condition. The new slab, damp proofing and structural repairs gave the client a weather-tight shell ready for fit-out as a workshop. The project demonstrated how targeted structural work can bring neglected buildings back into productive use.
