GOLDGRUBE ®

The GOLDGRUBE ® is a patented proprietary development for the separate storage of feces and urine in one container.

Our system complies with the standard of DIN 30762 „Prefabricated sanitation systems without connection to water supply and sewage system – Requirements and product features“ and is therefore state of the art. The basic concrete tank is also a regulated construction product (DIN EN 206-1, DIN 1045-2 and -4).

We have developed different sizes and variations to meet the needs of our customers. The heavy, large concrete design is a real alternative, especially for public toilets and residential buildings.

GOLDGRUBE® / Concrete

GOLDGRUBE ® made of concrete

The GOLDGRUBE ® concrete consists of a tight, monolithic concrete tank (according to DIN V 4034-1) with base – the basic tank, with installed internal septic tank and the concrete plate.
This variant  is statically highly loadable. It is installed in the ground, is buoyancy-proof and can be also designed to be flood-proof.
The foundation plate is prefabricated in the factory with all necessary pipes and openings. The tank is placed in the construction pit by the delivery truck, and once the pit has been backfilled, the plate is placed on top with a positive fit.
