• If neighbours share the access, it helps to let them know a lorry is coming.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Underground Drainage: choosing well

Covers for the location

Chamber covers are rated for loads, from pedestrian areas to drives. Tell us where each chamber sits.

Foul or surface water?

Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.

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.

Working out quantities for your Coleraine job

An 18 m run of 110 mm drain needs 6 pipes in 3 m lengths (or 3 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.

Ordering drainage for Coleraine: FAQs

What fall should a drain have?

Domestic drains are commonly laid at a gradient around 1:40 to 1:80 depending on the pipe size and flow; follow your approved design or your national drainage guidance (Approved Document H in England and Wales, Technical Handbook section 3 in Scotland, Technical Booklet N in Northern Ireland).

What size drainage pipe do I need?

110 mm is the standard size for most domestic underground foul and surface water drains; 160 mm is used for larger runs. Your design or building control will confirm.

Can you deliver drainage to a site with restricted access in Coleraine?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

How soon can drainage be delivered in Coleraine?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
