Oldroyd supplies recirculated polyester geotextiles both 600g/m2 and 1200g/m2. These geotextiles are suitable for use on sloping roofs where reservoir membranes are not in use. They give a good distribution of water and nutrients to a sedum roof and can take up between 21/2 and 5 litres/m2. The textile is 100% polyester and contains no natural fibres which can rot. This product can be supplied in several different dimensions.
