What does a block paved patio involve?
Block suits patios that join a block drive or path, small or awkward spaces where large slabs would need too many cuts, and gardens where you want a pattern such as basketweave or a circle feature. We lay patios to fall away from the house and below the damp-proof course, with edging that stops the blocks creeping into the lawn.
- Dig-out and compacted sub-base (around 100 mm for foot traffic)
- Optional sealer
- Blocks in your pattern, edges and cuts
- Falls away from the house and doors
- Layout marked out with you, including steps and doors
What we check on a Castlereagh survey
- Access for a mini-digger and how waste leaves the garden
- Outside taps, lights and cables
- Block range, colour, pattern and border to suit the house
- Edges against lawns, beds, fences and walls
- Levels against the damp-proof course and door thresholds
Do you need permission for a block paved patio in Castlereagh?
A patio or path behind the house does not usually need planning permission. Raised patios, listed buildings and flats can be different, so we check on the survey.
Paving in front of the house follows the front-garden rules: in Northern Ireland, front paving over 5 m² must be porous or drain within your boundary to be permitted development.
