We often come across questions about the efficiency of drainage systems. The correct selection of pipe diameter is crucial here. We take into account the type of soil and the size of the drained area. The correct placement of the filter geotextile is equally important.

In the case of areas with high groundwater levels, we recommend perimeter drainage systems. They include the installation of pipes around the building. This solution effectively protects the foundations from moisture. In our offer you will find complete sets for this type of installation.

Sustainable retention solutions are becoming increasingly popular. Our offer includes systems for managing rainwater. They enable its use for watering gardens or flushing toilets. This not only saves water, but also costs.

In the case of industrial areas, we often use stormwater pretreatment systems. We offer oil separators and settling tanks. They ensure compliance with environmental protection requirements. At the same time, they protect sewage systems from contamination.
