From contaminated soils to deep basement structures and high groundwater levels, below ground insulation faces some of the toughest challenges – and once installed, replacement is not an option. 

FOAMGLAS® insulation is designed for these demanding environments: 

• Proven performance under consistent groundwater pressure, certified for immersion depths up to 12 meters below groundwater level (DIBt Berlin)
• Maintains dimensional stability under permanent structural loads in deep basement applications
• Very good chemical resistance for brownfield sites
