Drainage Materials

Twinwall Drainage // Plastic

Twinwall pipes are used for both surface and storm water drainage. Manufactured from polypropylene or polyethylene, the outer wall is corrugated whilst the inner wall is smooth. The combination of heat welding together the two pipes gives the pipe its unique strength. Twinwall has many advantages over traditional materials through its lighter weight, fewer joints and robust construction. Twinwall drain is complimented by a broad range of fittings including couplings, bends, junctions and adaptors.

Available in diameters from 100mm to 600mm

Land Drainage Coil // UPVC

Modern surface water drainage and land management practices depend on effective control of the water table. Excess water can lead to restricted land access, reduced crop yields, erosion and environmental damage. TPS offer a wide range of UPVC and polypropylene drainage systems for surface and sub-surface drainage. TPS single wall land drainage coil is produced in accordance with BS 4962.

Available in diameters from 60mm to 225mm

Road Gullies // Concrete

A range of precast road gullies with 150mm trapped outlets. Gullies are produced monolithically on fully automated machines, providing a strong robust unit, needing no concrete surround and are not subject to flotation.

Available in diameters from 375 x750mm, 400 x 750mm, 450 x 900mm

Headwalls // Concrete

Precast concrete headwalls can be manufactured to suit a range of pipes from DN150mm up to DN900mm. They can be supplied with flap valves and grids if required. TPS concrete headwalls can accommodate pipework with an internal diameter of up to and including 1650mm ID and PCC box culverts up to 2400mm wide x 1500mm deep. Multiple pipe outlets can also be accommodated.

Easi-Base // Concrete

Bases are traditionally constructed manually in-situ using ready mix concrete which is trowled to form the base and benching. This practice is labour intensive and requires optimum site conditions to achieve a quality result. Easi-base is a precast concrete manhole base system incorporating a preformed polypropylene liner that provides an immediate water-tight structure for the efficient management of waste water in manhole construction. The integrated benching and channels in the polypropylene liner is the key to increased productivity, site safety and construction cost savings when compared to the traditional manually intensive methods of basing a manhole. Easi-bases are WRC approved and are supplied with an 80 year guarantee. Couple that with ‘Just in time’ delivery and pipe connection in as little as 30 minutes (traditional manhole base construction up to 48 hours) site productivity increases dramatically.

Available in diameters from 20mm to 630mm
