D-Rainclean®, the filtration channel with substrate serves for the treatment and the infiltration of contaminated surface water on roads, car parks, copper or zinc roofs. D-Rainclean is approved according to DIBt Z-84.2-1 and complies with the requirements of the DWA A-138 rules concerning contaminated surface water. Heavy metals are consolidated by adsorption, cation exchange and filtering. Oil sludges are biodegradable. The environmental load on sewage treatment plants, soils and on ground water in particular will be avoided.
The D-Rainclean® filtration channel comes as an open version for the subsequent planting of vegetation and as a closed version including a trafficable cast class D 40 t surface.
The Funke Company Group is one of the leading suppliers of pipes, moulded parts and profiles made of synthetic materials. Since its foundation the company has become a successfully acting group of companies reaching a top position in the German market thanks to its know-how, commitment and a continuous expanding range of products.
Hamm-Uentrop has been the company's production site since the autumn of 2000. In 2003 the administration was also relocated to the new site where innovative ideas are implemented rapidly and consistently. The company has an efficient organisation, from sales through to shipment as well as an excellent infrastructure. Three cargo quays ensure the reduction of lorry downtimes to a minimum. Access time for products manufactured on site is short. This is a benefit for customers.
In its information centre at the former Sendenhorst site, Funke focuses on a practice-oriented dialogue. Apart from an extensive permanent exhibition which is divided into numerous theme parks, the former administrative building also provides space for information events and training courses for representatives of the local authorities, staff members of engineering offices, civil engineering companies, architects as well as specialist dealers.
