With core stock in branches across the Keyline network we can get you the sewer drainage you need for your groundworks today.
Hepworth Clay Drainage System is the ideal choice for below ground drainage due to the superior strength and sustainability of its vitrified clay pipes. The 100% natural and recyclable pipes are tested and approved to BS EN 295 to ensure quality, and when correctly installed have a lifetime expectancy of at least 100 years.

The strength of clay drainage enables recycled aggregate to be used as a bedding material, which reduces costs and environmental impact during construction. It’s resistant to many chemicals and strong enough to accommodate non-uniform sub-soils on brownfield sites. Clay pipes’ resistance to high water pressure jetting means more blockages can be cleared first time. SuperSleve pipe has a Lifetime Jetting Guarantee (7,500 psi at a flow rate not exceeding 20 gals/min held static for 5 minutes). 

Hepworth Clay is the only calcinated roller kiln pipe in the world which produces a straighter pipe than traditional clay. In addition, short length pipes reduce cutting and construction time on site and help to ensure the integrity of the seal is never compromised.
