Watstop is an epoxy-cement waterproofing characterized by high resistance to negative pressure.  Product suitable in tunnels, cellars, basements, garages, elevator shafts, underground rooms and any wet support or surface affected by rising dampness.  Compared to traditional systems, that requires thicknesses not smaller than 1.5 cm - 1.18 inch, this product guarantees excellent waterproofing with just 2.5 – 3.0 mm / 0.10 - 0.12 inch.  Its extreme versatility allows to use it as vapour barrier for wet supports as encapsulating for rising dampness.  It can be applied by roll, brush or spatula and once dried it can be coated with plasters, smoothers, resins, adhesives, coatings, tiles or paints.
