Underground Drainage
Underground drainage systems safely transport wastewater and soil discharge away from homes and commercial buildings. Designed for long-term durability and compliance with UK building regulations, these systems include pipes, fittings and access components that ensure reliable performance below ground. Ideal for new builds, extensions and repair work, underground drainage provides essential protection against leaks, blockages and foundation damage.
Soil Pipes for Safe Removal of Waste and Soil Discharge
Soil pipes are the backbone of underground drainage systems, carrying wastewater from toilets, bathrooms, kitchens and utility rooms into the main drainage network. Made from strong, impact-resistant materials, soil pipes are engineered for long-lasting underground use and easy installation on domestic and commercial projects.
Soil Pipe Fittings for Secure, Leak-Free Connections
Soil pipe fittings include bends, junctions, couplers, reducers and access points that ensure efficient system flow and secure connections between pipe sections. These soil pipe fittings are essential for creating smooth directional changes, adapting pipe sizes and maintaining a watertight drainage system.
110mm Soil Pipe for Standard Underground Drainage Installations
110mm soil pipe is the most commonly used size for underground and above-ground soil systems in the UK. Suitable for residential and light commercial applications, 110mm soil pipe provides strong flow capacity, compatibility with all major fittings and reliable performance in both new installations and repairs.
Designed for Durability, Strength and UK Building Compliance
Our underground drainage products are manufactured to meet UK standards for load resistance, chemical resistance and flow efficiency. They are engineered to withstand heavy ground pressure, vehicle loading (when supported correctly) and environmental conditions.
