Comparison of the Base Plate of Our Pump Stations with Conventional Construction Methods
In rain and wastewater technology, stable and durable solutions are crucial. Our DORANT and HEKANT pump stations set new standards in this regard.

Our System: Our pump stations consist of a three-part shaft system, which includes a cylindrical shaft made of double-walled PE-HD spiral pipe, a base plate, and a top plate made of PE-HD with a reinforced concrete core. These parts are seamlessly welded together, ensuring maximum stability. The base plate, designed as a cantilever slab, serves as an effective buoyancy safeguard with its overhang.
Conventional Construction Method: In conventional construction, a concrete base plate is cast by the contractor, on which the PE-HD shaft is placed. There is no fixed connection between the container and the base plate. Groundwater presses directly against the PE-HD shaft, which can lead to deformations and damage to the armatures at high groundwater levels. This results in high follow-up costs due to necessary repairs.

Comparison:
Kordes System:
- Base plate made of reinforced concrete
- Stable against groundwater pressure

Common Design
- Base plate often made of plastic
- Risk of bulging and deformation
- Stress and damage to the armatures, high repair costs
