Burdens South East are offering a unique service to supply plastic drainage systems for adoptable sewers. In an exclusive partnership with Polypipe and Uponor, Burdens are now stockists of Ultra Fortis and Ridgisewer pipe and fittings from our depots in the South East.

UPONOR Ultra Fortis
With pipe diameters up to 300mm, Ultra Fortis has been approved and kitemarked in accordance with WIS 4-35-01 and achieves the 4000 psi water jetting resistance requested by a number of adopting authorities in the UK and witnessed by BSI.

POLYPIPE Ridgisewer
Available in 6 sizes from 400-900mm, Ridgisewer is manufactured in full compliance with WIS 4-35-01 from high strength polypropylene, offering stiffness combined with exceptional durability.
Unlike clay and concrete, both leak-tight systems are easy to install and have the ability to accommodate ground movement without fracture and leakage.

• Impact resistance 50 times higher than clay
• Durable long life material

• Excellent leak tight system that remains intact even under extreme site conditions
• Strong yet flexible design allows pipeline to withstand ground movement and differential settlement
