TERRAM Hydrotex™ - geocomposite for rail ballasted trackbeds

TERRAM Hydrotex™ is a patented flexible multi-layer anti-clay pumping geocomposite for use in rail ballasted track bed applications where there is a risk of clay slurry formation. It consists of a micro filter core thermally laminated between two outer geotextiles. The two protective geotextiles are non-woven, needle-punched and thermally-bonded, and manufactured from UV-stabilised, high-tenacity, virgin polypropylene fibres.

Hydrotex™ is specifically designed to filter fine silt and clay particles whilst remaining sufficiently permeable to permit the passage of water particles under very low hydraulic gradients.

Key features and benefits

• Hydrotex is made to replace 100mm of sand and geotextile. Its use saves time and money as well as lowering the projects carbon footprint

• More permeable than the previous versions, water can pass through more easily than any products in the market

• Compared to traditional solutions, Hydrotex does not require excavation, material removal or sand importation
