Clark-Drain introduces Technodrain into UK construction
Clark-Drain Ltd unveils Technodrain®, a new addition to its popular linear drainage range that broadens the choice for UK construction.
Designed for surface water management, the versatility of Technodrain® enables it to be used across all construction environments as a light, robust, technical solution for run-off surface design.
Made from High Density Polyethylene, Technodrain® encompasses all load classes (A15-F900) in accordance with European standard EN 1433, comprising an array of grating design options in ductile iron, galvanised steel and stainless steel.
The Technodrain® system will be available in 100mm, 150mm, 200mm and 300mm internal widths.
With the advantage of light-weight, polyethylene – e.g. the EXEL 200HV has a 42.61 l/s hydraulic capacity ideal for use in road drainage and car parks and weighs 26.1kg, complete with D400 ductile iron grating – its size to weight ratio maximises savings in transport and installation cost.
Technologically advanced, Technodrain® is resistant to temperature change with a thermal range between -60OC and +100OC. It is also resistant to a wide range of acids, salts and hydrocarbons so that it can be used in challenging environments such as chemical plants, petrol stations and surfaces where ant-freeze salts are used.
Technodrain® incorporates many other benefits. Its robust design adds to its sustainable life, whilst installation is eased with tongue and groove joints enabling the connection of multiple channels with a ready-mounted grate. Its preformed lateral and vertical channel outlets also provide quick and easy connection to discharge pipes.
Furthermore, project design is supported by integrated Tee-and Cross-section joints that can adapt the drainage line, enabling control over the accuracy and cost effectiveness of the whole system.
An important additional accessory is the Technodrain® sump unit. It can be installed as a terminal unit off the line or as a central element of two converging lines. The sump is equipped with an optional anti-odour siphon that can be removed easily for cleaning purposes and a grating to filter leaves and debris. Use of the sump allows you to increase the out-flow diameter of all channels up to Ø200.
Selection of Technodrain range
John Carter, Head of Sales and Marketing at Clark-Drain comments: “Both for the contractor and the operator, Technodrain offers technical innovation and a high degree of cost saving, whilst providing a highly efficient system for surface water design and management right across the construction project spectrum”

Clark-Drain design and manufacture bespoke flush covers for Queen Mary University
Clark-Drain design and manufacture bespoke flush covers for Queen Mary University of London
When three underground chambers were required as part of a project to install a new emergency generator at a university campus in London's East End, three specially fabricated flush top covers were supplied to ensure access.
The project saw the installation of a 350kVa generator and steel mast supporting a 26m high exhaust flue, which serve as emergency back-up for the university. The design called for 150mm ducting for cables to run beneath a new tarmac surface, with three deep brickwork access chambers.
These chambers each needed bespoke 1m x 1.5m access covers.
London Surfacing Ltd, the main contractors, asked several suppliers including Clark-Drain to quote for the supply contract. Working from supplied specifications, Clark-Drain’s Specials Department created a proposal, with designs for the three covers.
London Surfacing’s Chris Stylianou says: “We were aware of Clark-Drain’s especially wide product portfolio and manufacturing capability, so we asked them what they could do for us. They won the contract not only on their ability to meet our specifications and quality standards, but also because they scored well on affordability.”
The covers were designed and fabricated in-house at Clark-Drain’s UK manufacturing facility. They were supplied to London Surfacing through George Lines, the Slough-based civils and landscape merchants.
Each of the chambers is located in an area with different maximum loads, so each cover was made to reflect this. In a pedestrian area, the cover is made to FACTA Class AAA standards. The other two meet Class B and D standards to cope with slow moving vehicular traffic. All three covers include sealing gaskets and locking systems to prevent unauthorised entry.
Chris Stylianou says: “The covers needed to be bigger than standard manhole covers so it called for tailor-made products. At Clark-Drain’s suggestion we opted for covers consisting of four parts in order to make removal easier when access to a chamber is required.”
The chequer plate covers were galvanised by Clark-Drain to BS EN ISO 1461, the key standard for galvanised coatings on iron and steel components. Application of this standard should ensure a 25-30 years lifespan with regular maintenance.
Along with specialist knowledge and manufacturing capability, Clark-Drain provides dedicated support services to projects like this one. Early involvement and site visits enable our team to advise on the best solution. Subsequent assistance including technical consultation and CAD engineering supports the quality and timely delivery of our customers’ projects.
