Backfill structure
The backfill structure is built in compacted layers with the insertion of a woven geotextile, regularly spaced. This allows stiffened embankments and earth walls to be built economically and quickly.
Foundation drainage
The drainage mat or drainage blanket, traditionally of fine gravel, can be economically and reliably replaced by the needle-punched nonwoven composite sheet with a network of mini-drains: teradrain®.
Needle-punched nonwoven composite sheet with a network of mini-drains for filtration and drainage: teradrain.
