Rapid filling by x15 expansion
ECOPOLFOAM BO-D is a two-component expansive polyurea-silicate foam, injectable and solvent-free, that reacts quickly for use in wet conditions. It is ideal for ground consolidation, water sealing, and crack filling in tunnels using tunnel boring machines. With high compression resistance and a high expansion factor, this foam is resistant to acids and bases and is insoluble in water. It is easily applied using a two-component pump and mixing gun, operating effectively between 5°C and 25°C.
