Choosing drainage

Covers for the location

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

Building over or near a sewer

Building near a public sewer may need permission from the water company. Check before you dig.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Sizing your order

An 8 m run of 110 mm drain needs 3 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.

Getting drainage onto your Welling site

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Welling is inside our standard mainland delivery area.

• On busy streets in Welling, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Underground Drainage questions

Is there a minimum order for delivery to Welling?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

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

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.

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.

What do I bed drainage pipe in?

Usually pea gravel or a similar granular material around the pipe. We can add it to the order as bulk bags.
