Solutions to your challenges Stormwater Management Underground tank Rainwater Harvesting with System GRAF offers an extensive range of products for water resource management. GRAF provides local solutions to global challenges, such as protecting water courses or preventing flooding, with typical German quality. Environmental products from recycled raw materials Over 70  of the raw materials % used by GRAF are recycled. In-house recycling of raw materials allows us to ensure consistently high raw material quality and to make all the products in our value-added chain highly sustainable. All...

Groundwater recharge disturbed Infiltration boosts groundwater recharge hydraulic peaks invest in centralized systems like huge pipeworks hydraulic peaks to a minimum l No big diameters for pipeworks necessary l Less influences from peak flows Main drainage connection Stormwater Management Stormwater Management Storm? Floods? We have the solution! Groundwater level sinks Groundwater level rises The infiltration and retention of rainwater locally offers considerable advantages over the previously customary draining into combined wastewater/separate sewage systems: l Promotes groundwater...

To save space when transporting the EcoBloc maxx and EcoBloc light modules, they can be stacked inside one another. This minimizes transport costs, storage space and CO2 emissions. The EcoBloc ground plate forms the base for the relevant EcoBloc system. Up to 14 EcoBloc modules can be placed on one ground plate. The sides are sealed with EcoBloc end plates. The EcoBloc system can therefore be adapted to individual requirements.

Technical data XTop and XFlow The solution The increasing sealing of building areas such as parking lots for supermarkets are problematic especially in heavy rain events. Usage of permeable surfaces like paving stones with wide joints or grass pavers is important to prevent flooding. Stormwater Management EcoBloc light* Vario 800 flex shaft system Infiltration tunnel Gross volume Net volume Storage coefficient Inspectable High pressure jetting possible EcoBloc maxx* The water is then transported to the underground where the XFlow shows its strengths. XFlow significantly improves the...

Benefits in operation and maintenance Surface Drainage Rainwater falls on permeable surfaces like green fields, sand banks, gravel beds. XTop can be used to stabilise and fix loose granular material or green fields and serve best direct permeability. Without XTop With XTop Stormwater Management Stormwater Management puddles access on lawn areas l Permeable ground improvement l Fixing loose granular surfaces & erosion l Vehicle ground reinforcement appearance XTOP VIDEO Without XTop With XTop with high punctual loadings Without XTop Otto Graf GmbH With XTop Otto Graf GmbH

Benefits in operation and maintenance Interlayer Drainage Rainwater falls on semi-permeable surfaces like pavements or other and local conditions prevent fast permeability. To improve the storage capacities of wide areas, XFlow can be used next to surface from 150 – 500 mm below level.
