Tree root protection system

ProtectaWebWrekin Products ProtectaWeb tree root protection is an established and proven no-dig method of constructing access ways or parking areas in close proximity to nearby trees, without causing them undue stress that would damage or ultimately kill them.

ProtectaWeb is a matrix that contains and confines granular infill. This provides a stable, uncompacted, composite matrix with an enhanced angle of internal friction that significantly reduces the imposed loads on the soil and tree roots beneath. ProtectaWeb’s perforated cell walls gives lateral drainage, thus minimising hydrostatic build up and ensures the maximum supply of water to the tree roots, even when installed on a gradient.
