Working out quantities for your County Antrim job
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.
Before your County Antrim delivery arrives
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.
- On busy streets in County Antrim, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- Give us the full postcode for the drop point; deliveries around BT are priced to the exact address.
Picking the right product
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 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.
Your questions answered
Is there a minimum order for delivery to County Antrim?
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.
Do you deliver drainage to County Antrim?
Yes. We deliver across County Antrim, including BT. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.
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).
Can I connect to the public sewer?
New connections to a public sewer usually need approval from the local water company.
