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

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 foundation plate / concrete cover plate.
The variant made of concrete is statically highly loadable. It is installed in the ground, is buoyancy-proof and can be designed to be flood-proof.
The foundation or cover 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 foundation or cover plate is placed on top with a positive fit.

There are various installation options. We provide you with these under data sheets – German only.

Overview: GOLDGRUBE® versions

The following table shows the GOLDGRUBE® in its different versions. All versions comply with the DIN 30762 standard. Some of them can be used in both private and public areas, but not all of them make sense everywhere. The usage data are estimated values from the professional world. We will be happy to assist you in making the right choice.

The versions made of concrete can all both be integrated into a house and thus then have a round cover instead of a foundation plate. With a foundation plate, they are a “stand-alone solution”. The foundation plates or cover plates can have three different surface textures: concrete rough, partially concreted or prefabricated floor.

The data sheets provide further details around the different versions of the GOLDGRUBE®. Note that this data sheets are only in German.
