Drizoro - quick setting mortar for leveling manholes and Watmat repairs

Watmat is a quick-setting mortar for setting, leveling manhole covers and repairing floors. It is pre-mixed with special silicones, cements and other additives. It is available as a ready-to-use product - to be mixed with water and is available in two variants: Watmat W - winter (at ambient temperature up to 15 C), Watmat S - summer (from 15 C). It has good adhesion to the substrate.

Application

• immediate repair, setting and leveling of newly installed manholes in
• repair of industrial floors
• quick repairs in road construction - resumption of traffic after 2 hours
• quick deposition of drain grates on floors
• repair of structures in a vertical plane
• use in poorly ventilated rooms - thanks to its non-toxic and odorless nature
