The D-Raintank® manages two important tasks: subsurface water retention and infiltration. The D-Raintank® combines high storage capacity with an enormous stability for underground use. It is an element made up of statically calculated grids, completely enclosed by geotextile. The single tanks may be positioned according to the space conditions. This combination allows for rainwater reservoirs to be created where atmospheric water be first collected and then drained away or piped.
Surfaces to be drained include:
Terrace and yard surfaces
Park and footpaths
Following the removal of substances in the framework of preparatory treatment measures, the surface water from the following surfaces can then be drained:
Car parks/ garage accesses
Other sealed surfaces
The federal state-specifications must be taken into consideration since they vary from one federal state to the other.
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.
