Underground Drainage

This section contains all of our standard PVC underground drainage systems, including 110mm and 160mm—popular products used in everyday drainage projects, as well as larger sizes upon request. Alongside these, we offer durable cast iron pipes and fittings, meticulously engineered to withstand the test of time, with a lifespan extending beyond a century.

We offer single or bulk purchase options - our bulk purchases page below is ideal for buying materials for a whole site or project. You can also buy subfloor ventilation products in this section.

In this section you will find standard 110mm and 160mm pipes and fittings; cast iron pipes and fittings; as well as channel drainage (slotted drains for use in draining stormwater from driveways and patios), sewage treatment plants for properties that are not connected to mains drainage and subfloor ventilation products that are generally installed when the first drainage fittings are introduced to the site.

FEATURES & BENEFITS OF THE 110MM & 160MM DRAINAGE SYSTEM

Our 110mm Drainage, which is the most common size for domestic drainage in the UK, is manufactured to BS-EN 1401 and BS 4660.

All of our underground drainage pipes and the majority of our fittings are manufactured from UPVC, and all pipes, bends, gullies and connectors in the drainage system are commonly manufactured in a Golden Brown colour.

FEATURES & BENEFITS OF THE HALIFAX CAST IRON DRAINAGE SYSTEM

The Halifax cast iron drainage system offers superior durability and performance. Cast iron is an exceptionally robust and long-lasting material that can withstand heavy loads, harsh environments, and years of use.

In addition to its strength and longevity, the Halifax cast iron system is also designed for easy installation and maintenance. The system features a wide range of compatible fittings and accessories that simplify integrating it with other plumbing components.

COMPATIBILITY WITH SOIL & WASTE SYSTEMS

Our underground drainage products are fully compatible with our above-ground PVC-u soil and waste systems. In this section, you will find all of the most commonly used drainage bends and different types of connectors and adaptors along with gully traps and other basic components of the drainage system. This system is interchangeable with all other leading manufacturers of 110mm and 160mm systems.

Additionally, our Halifa drain system is also compatible with Halifax cast iron soil and cast iron mech 416 systems. The standard couplings within the Halifax Soil and Drain systems are suitable for connecting products made of other materials into the system, as long as the external diameters are the same.
