Drainage product and access cover leader, Clark-Drain, has added a choice of Road Gullies certified to the Highways Authority Product Approval Scheme (HAPAS) to strengthen its underground range.
The Gullies are designed for quick and easy installation, in urban areas and on roads, for direct connection to PVC-U plastic pipe systems or with a suitable adaptor, also supplied, to clay and twin wall drainage systems. The gully outlet is 160mm diameter as standard with 178mm diameter available when using the outlet adaptor.
Manufactured from High Density Polyethylene the Gullies will be sold alongside Clark-Drain’s Ductile Iron Gully Grates which are BSI Kitemark Certified to BS EN124:1994 for a D400 (40 tonnes) load rating.
Dave Westacott, National Sales Manager at Clark-Drain says: “The addition of the Road Gullies supports the tendency in new installations to use plastic gully pots instead of pre-cast concrete. They are easier to handle, require less people and no heavy lifting equipment, resulting in cost savings. The plastic gullies also have a similar lifespan to pre-cast concrete when installed with a concrete surround.”
The practical design of the road gullies will also support the maintenance regimes of Local Authorities and their responsibilities for odour control.
Dave continues. “When used as a trapped system the gullies are airtight to prevent smells rising up from the existing sewers. This is mandatory for connections made to a Foul or Combined system, and is recommended for connections to Surface Water systems. It is also easy to maintain with a removable rubber plug that enables the gully to be rodded or cleaned using conventional equipment and machinery to clear debris from the drainage channels. The gullies have also been tested under HAPAS requirements to be fully watertight”
The Road Gullies have a clear opening of 450mm and will be offered in two depth sizes to 750mm and 900mm depth with water holding capacities of 83 litres and 107 litres volume respectively.
