Durable and Economical
Unlike in a traditional roofing system where the membrane is attached to the substrate by adhesive or plates and screws, in a waterproofing system you are able to loosely lay the Sarnafil G 476 membrane down without any attachment due to the fact that the membrane is the bottom layer in the system and will have things like pavers or soil on top to keep it down. The Sarnafil G 476’s seams are also hot-air welded for maximum water tightness.
Below are some of the reasons why a loose-laid waterproofing system might be the best fit for your project.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete that can be used in areas such as the floor or the roof.
Concrete pavers are made in a factory rather than poured on site. Concrete pavers are a mixture of concrete and some type of coloring agent poured into a mold of some shape and allowed to set.
Adjustable Paver Pedestal
Paver pedestals go under the paver and can be adjusted up or down to make your plaza deck level. Pedestals are designed to hold the weight of the paver as well as foot or vehicle traffic.
