Services
Sealing systems with substance.
From technical consulting to professional execution: We combine suitable materials, experience, and quality workmanship.
Four service areas
The right solution for every layer.
We look beyond the individual product to the entire system: subgrade, sealing, protection, drainage, and final use must all work together reliably.

Geomembranes & geosynthetic clay liners (GCLs)
Sealing Systems
We develop permanently reliable sealing systems for stormwater retention basins, industrial areas, structures, and facilities containing substances hazardous to water. For this purpose, we supply, install, and weld geomembranes made of HDPE, PVC, EVA, and FPO as well as geosynthetic clay liners (GCLs) – including connections, details, and documented quality control.
- Installation & welding according to regulations
- Sealing of structures, basins, and landfills
- Leak testing and seam documentation
- WHG-certified specialist company under § 62

Geogrids & reinforcement fabrics
Reinforcement
Geogrids absorb tensile forces in the soil, thereby improving load-bearing capacity and load distribution. We select the appropriate system for the subsoil and load and install it professionally for construction roads, working platforms, embankments, and stable foundation pads.
- Soil reinforcement & load distribution
- Steep embankments and support structures
- Bearing and separation layers for construction roads
- Low-settlement foundation pads

Drainage mats & erosion control
Drainage & Erosion Control
Drainage mats create a reliable path for seepage and surface water. Together with filter geotextiles, protective layers, and erosion control systems, they prevent waterlogging, protect sealing systems, and provide long-term protection for embankments, dams, and covers against scouring.
- Area drainage above sealing layers
- Filter, separation, and protective layers
- Embankment and dam stabilization
- Vegetatable erosion control

Groundwater pressure relief valve
Groundwater pressure relief
Our proprietary development controllably relieves rising groundwater pressure beneath geomembrane-lined basins – without the geomembrane floating up and without complex maintenance.
- Protection against liner uplift
- Low-maintenance and retrofittable
- For stormwater retention and firefighting water basins
- Development, manufacturing, and installation from a single source
