Patio Drainage in Sidcup: Building for Wet Winters
A Sidcup patio that pools and green-over by winter usually has one cause: poor drainage. Here's how we build sub-bases, falls and drainage so a patio sheds water for years.
Why Sidcup patios fail
Most patio problems in Sidcup — pooling water, green algae, slabs that lift and settle unevenly — trace back to one thing: the base. A patio laid on a thin layer of sand over clay will move, hold water and age badly. Build the base right and the surface looks after itself.
The sub-base is everything
Every Sidcup patio we install begins below the slab:
- Excavation to the right depth for your ground and finished level.
- MOT type 1 sub-base laid, compacted in layers.
- Screeding to a precise fall — the gentle slope that sends water off the surface.
- Laying porcelain or sandstone to tight joints with premium grout.
Where extra drainage is needed
On flat Sidcup plots or where water has nowhere to go, we add:
- Channel drainage (Aco drains) at the edge to collect and carry run-off.
- Soakaways where ground and space allow.
- Coordinated levels so the patio, lawn and borders all shed water in the same direction.
SUDS and the responsible approach
Modern paving should manage water on-site rather than dumping it into the drains. A proper sub-base and fall keep your patio SUDS-compliant — better for your garden, better for the street, and increasingly what planning expects.
