Sealing systems in groundwater protection: installation by a certified WHG specialist

What is a stormwater retention basin?

A stormwater retention basin is a facility that temporarily stores excess rainwater and releases it in a controlled manner. These basins prevent flooding and regulate water runoff, particularly in highly paved urban areas, and are an important component of flood protection and water management.

Why is sealing crucial?

Sealing ensures the buffering capacity and structural integrity of the basin. Although rainwater is usually not heavily contaminated, a sealing system prevents infiltration into the groundwater and ensures that water is retained and discharged in a controlled manner — securing the functionality and longevity of the basin.

What is a hydropower canal?

A hydropower canal, also known as a headrace canal, is an artificial waterway that channels water from a river or reservoir to a turbine in a hydropower plant. These canals are designed to transport large volumes of water with minimal energy loss and are a key component of hydropower plant infrastructure for efficient energy generation.

Why is sealing crucial?

Sealing prevents water loss through seepage and maintains the structural integrity of the canal. Without effective sealing, erosion, material fatigue and significant efficiency losses can occur. A reliable sealing system keeps water flowing unobstructed to the turbine, maximising the performance and lifespan of the plant.

What does M TS E mean?

M TS E stands for the German guideline on construction methods for technical safety measures when using soils and construction materials with environmentally relevant substances in earthworks. It defines methods that allow such materials to be used safely while preventing harmful substances from entering the environment.

Why is sealing crucial?

Sealing prevents the spread of contaminants and protects the environment and groundwater. Insufficient sealing can cause significant environmental damage; an effective sealing layer safely contains the environmentally relevant soils and construction materials.
