Oldroyd Gtx20 is a studded geotextile cavity drainage membrane with a geotextile filter fleece - sometimes referred to as a 'fin drain', a 'geocomposite membrane' or a 'geocomposite.' It benefits from a large stud size (20 mm high) which gives it the highest flow capacity in the Oldroyd Gtx family.
