Groundwater Protection

The focus of HUESKER’s Groundwater Protection segment is on protecting clean natural resources against contamination. By reliably preventing the infiltration of rainwater into contaminated soils, our products permanently guard against the escape of pollutants.

For long-term groundwater protection, it is also important to prevent water-polluting liquids from contaminating clean soils and endangering the underlying water table.

Roads in water protection areas

The provision of adequate measures to eliminate any risk to the groundwater in water protection areas is always a stiff test for designers. Tektoseal® lining systems prevent the infiltration of hazardous liquids into the groundwater via paved or grass verges.

The incorporation of contaminated soils in new landscape features is a complex task. HUESKER products such as Tektoseal® or Fortrac®, for instance, facilitate the reuse of contaminated material in structures such as noise bunds. Such applications give top priority to the efficient sealing of earthworks to prevent the escape of contaminated leechates.

Airfield construction

On airfield projects, the runway shoulders are subject to special construction regulations. Due to the action of the turbines, all aircraft movements cause de-icing agents, de-icing salts and fuels such as kerosene to be scattered across the surrounding area. The controlled collection of these water-polluting substances is made possible through the use of HUESKER geosynthetics, namely bentonite mats (GCLs), which prevent seepage into the ground, even beyond the paved surfaces. This, in conjunction with suitable drainage products, prevents any contamination of the clean soil.

Railways in water protection areas

The track beds of railway lines running through water protection areas are subject to stringent requirements – the aim being to prevent contamination by fuel and lubricants of the groundwater in the area along the track. Additional precautions may be needed to cater for exceptional situations caused by accidents that involve the escape of water-polluting materials. Here too, HUESKER’s Tektoseal® bentonite mat plays a central role in the groundwater protection system.
