A quick quantity check

A 12 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.

Planning the drop in County Londonderry

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Picking the right product

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.

Do you deliver drainage to trades and homeowners in County Londonderry?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Can I add other materials to my County Londonderry delivery?

Yes. Put everything on one list, from drainage to fixings and PPE, and we will price it as one delivery where the products can travel together.

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).
