The revolutionary Funke HS®-Underground Drainage Pipe System

HS® Drainage & Sewer System

Stormwater Management are the stockist and distributor for the revolutionary Funke HS® Drainage & Sewer System.

The HS® range is a direct alternative to clay & concrete systems for adoptable drainage & sewer networks with acceptance/approval given ALL 11 water companies.

Due to the HS® range being available in a variety of diameters from 110mm to 800mm and a range of pipe lengths up to 5m there are now 5 major house-builders who have specified the system.  The diameters 200mm – 800mm are perfectly suitable for housing developments and the drainage of rainwater and wastewater.

The general concept gives cost savings on site (against weight, manpower, plant and installation time) and also provides fittings to SDR34 which, again, reduce costs. The ground-breaking product also offers major Health & Safety advantages for installers. With the ease of handling there will be a subsequent reduction in plant and machinery, make the HS® range a very safe and economical adoptable sewer system.

A complete system that leaves nothing to be desired

The low weight makes handling easier on the construction site, while high resistance to chemical influences and corrosion as well as optimal hydraulic properties ensure that sewer systems constructed from plastic pipes also meet the requirements of durability and low maintenance.

The colours blue and brown

This approach has played a major role in the success story of the HS®-Underground Drainage Pipe System.

Pipes and fittings can still be identified without any issues even many years after installation due to their colour coding in blue (rainwater) and brown (waste water).

25 years of the HS®-Underground Drainage Pipe System

Tried-and-tested – these pipes can withstand high loads

All HS®-Pipes and HS®-Fittings have increased walls and come with increased ring stiffness. They are therefore also suitable for laying under public traffic areas (from 0.5 m laying depth).

Advantages of the material

Due to its high hardness and robustness, PVC-U also has a significantly lower creep tendency than PP and PE. Unlike polyolefins, which can only be welded, PVC-U can be both welded and bonded. As a result of the higher modulus of elasticity, PVC-U pipes have much higher longitudinal bending stiffness than PP pipes, which minimises the risk of lower pipe bends, for example.
