FREE SHIPPING
Our underground downspout drain liner is a heavy-duty waterproof liner which can be used to line a downspout drain channel to prevent water intrusion into the surrounding area. This can be particularly useful in drainage channels adjacent to sidewalks or home foundations where water intrusion could cause significant damage. The liner is composed of HDPE plastic and is both puncture and tear resistant. The liner is available in various thicknesses ranging from 30 mil to 100 mil and in roll widths from 10” to 60”. The liner is able to bend to conform to various trench widths. Our HDPE is UV resistant and provides a projected 100 year lifespan when buried underground. Our HDPE rolls are manufactured in the USA.
