Root Barriers (Invasive Species)

Rootbarrier 400

Rootbarrier 400 is an impermeable woven HDPE root barrier coated with a triple layer of film LDPE to prevent roots from lifting concrete, tarmac or other paving.

Mature tree roots can cause extensive damage to pipework and pavements. Tree roots need oxygen, water and a soil density low enough to penetrate and in urban areas in particular, tree roots often struggle to find a suitable route through the ground, so the disturbed soil around cables, pipework and paved areas is ideal.

Rootbarrier 400 can be installed vertically or horizontally to line trenches and comes in rolls 1.83m x 50m; alternatively, panels can be made to order up to 40m wide and 150m long.
