Underground Drainage
Our range of underground drainage systems is designed to safely carry wastewater and surface water away from buildings into the main sewer or soakaway. Whether you are installing a new system or replacing existing pipework, this collection includes a wide choice of drainage pipes and fittings suitable for projects across the UK.
All products in this collection are suitable for below ground use and compatible with standard UK drainage systems. If you are working with specific pipe sizes, please view our 110mm Underground Drainage and 160mm Underground Drainage collections for dedicated systems and fittings.
Underground Drainage for Every Project
Different projects require different drainage capacities. From standard domestic systems to higher capacity installations, our underground drainage products are suitable for a wide variety of applications.
- Domestic drainage systems for houses and extensions
- Higher capacity systems for larger properties
- Commercial drainage and multi connection systems
110mm Underground Drainage
110mm underground drainage is the most commonly used size for residential systems in the UK. It is designed to carry wastewater from toilets, sinks, baths and general household use. This system is widely used in new builds, renovations and extensions due to its reliability and ease of installation.
Browse our 110mm Underground Drainage range for pipes, bends, junctions, gullies and access components designed for everyday drainage systems.
160mm Underground Drainage
160mm underground drainage is used where greater capacity is required. It is ideal for larger properties, longer drainage runs and commercial applications where higher volumes of water need to be managed efficiently.
Explore our 160mm Underground Drainage range for a full selection of pipes, fittings and inspection components suited to larger scale drainage installations.
Drainage Pipes and Fittings
A complete underground drainage system relies on the correct combination of drainage pipes and fittings. From straight pipe runs to directional changes and branch connections, each component plays a key role in maintaining smooth water flow and long term performance.
Inspection Chambers and Access
Inspection chambers provide essential access to underground drainage systems for maintenance and cleaning. They allow for easy inspection of pipework and help ensure the system continues to operate efficiently over time.
Bottle Gullies and Surface Water Drainage
Bottle gullies and hoppers are used to collect wastewater and surface water from external sources such as kitchens, downpipes and paved areas. These components help direct water into the underground drainage system while preventing foul odours from escaping.
