Sudstech The Sudstech system, designed and developed by Langford Direct Ltd.,offers a sustainable drainage solution that replicates the natural infiltration method of the water cycle that is highly efficient and maintenance free. With the ability to absorb up to 50,000 litres of water per square metre, per hour, Sudstech eliminates the need for expensive, additional drainage systems which are subject to frequent blockages and maintenance. Unlike resin systems which are installed over concrete or tarmac Sudstech, is installed directly onto an aggregate base. The paving is tested at The British research establishment to withstand freeze thaw conditions without cracking or delaminating. The porous material is created using natural stones combined with a specially developed resin, which allows rainfall to evenly saturate through the surface into the ground and eventually finding its way to the water course. The unique formation of the material allows grit, dirt and other particulates which may cause the system to block, to agitate through the surface to prevent clogging ,making Sudstech particularly suitable for applications such as, public realm spaces, foot paths and car parks, as it will not require regular maintenance causing the area to be closed for public use.. Sudstech can be specified in a range of colours to provide an attractive paving solution that can be used to match any landscaping theme. The material uses varying grades of angular aggregates to deliver maximised strength and durability for a sleek, porous surface that can withstand all usages without compromising the quality of the material. Following many years of research, development and testing, Sudstech conforms to the latest SUDS legislations created alongside the Water Management Act 2010, which requires porous materials to completely prevent surface water run-off and build up. With its large water capacity, Sudstech can contribute to the control of flooding caused by climate change in public areas and other environmental impacts of hard paving water build up. All applications of Sudstech can be modified to meet each specification requirement, such as colour variation and weight loading capacity 88 and can provide up to 4 BREEAM accreditations. Due to its SUDS compliancy, applications of Sudstech do not require planning permission. Sudstech is also guaranteed to remain porous for at least 10 years Further information on Sudstech is available from the company on 0161 2121617, by emailing: [email protected] or by visiting the company’s website at www.sudstech.co.uk
