Network rail approval for E'GRID 3030L

E’GRID 3030L is approved by Network Rail with Certificate of Full Acceptance number PA05/05826.

To achieve this E’GRID underwent a vigorous auditing process, including having to provide justification for the product by demonstrating its monetary, safety and performance benefits to Network Rail.

E’GRID 3030L polypropylene biaxial geogrid features a large aperture, suited to reinforcing the railway ballast layer. This reduces ballast settlement and extends the time between subsequent maintenance work following ballast renewal. The reinforcing element is a Specific Condition of Network Rail acceptance, which requires CE Marking in accordance with BS EN 13250 for reinforcement materials used in contact with ballast.

The high tensile strength design of E’GRID is widely recognised as an effective method of stabilising ballast or soil through reinforcement. The high-strength polymer grid interlocks with the ballast or stone, confining the material to improve load dispersal and limit lateral movement under load.
