Before you order drainage
Foul or surface water?
Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.
Covers for the location
Chamber covers are rated for loads, from pedestrian areas to drives. Tell us where each chamber sits.
In Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.
How much will you need?
A 10 m run of 110 mm drain needs 4 pipes in 3 m lengths (or 2 in 6 m lengths), plus a bend or junction at each change of direction and an inspection chamber where your design shows one. Add pea gravel for bedding and surround and we will price the lot together.
