Customer Reviews
After an initial problem with shipping the company resolved the issue very responsibly. Great customer service. This product is not extremely flexible but is very workable. I am using it on 16 inch on center joists that are already tilted for drainage. The worst part is screwing the downspout on. I guess I'm not cutting it correctly. I have a very small gap at the corners of the cut. No problem. I'm just going to apply a small amount of silicone caulk around the spout on the underside. I'm using 6 inch wide butyl tape at the overlaps (Nashua window and door flashing tape from Home Depot. I've also used Trex Rainescape butyl tape but it's double the price). The product can be heated with a hair dryer or heat gun for molding. Overall, other than the shipping problem that the company fixed, I'm pleased with the product and would use it again.
Very easy install. Cross bracing at the midpoint of the joist bay helped to set & maintain slope. Very pleased with this Canadian product that (I think) does a better job than rain escape at a fraction of the cost!
C'est une membrane ridige, comme clouer une crazy carpet sur un patio. Elle arrive dans un rouleau avec plein de plis partout qui font en sorte que l'eau ne s'écoule pas bien même avec une pente.
cest pas serieux...
Product not suitable for use in southern US. Any amount of heat causes it to wrinkle up. Making it hard to install and will continue to wrinkle after install. I placed it under Trex cover deck 10 feet in the air. The heat off the Trex boards just intensified the ripples. And yes it is fastened down to the joist well.
Works great. Turned our under deck area into a dry area. Great place to barbecue in the rain.
