Agent for injection, composed of concentrated silicone micro-emulsion for creating a chemical barrier against rising damp in the masonry. Mapestop is used to form a chemical barrier against rising damp through capillary pores that are always present in construction materials. In particular, Mapestop is used to repair old or new full brick and/or stone masonry that are built on damp sites or near water, mixed brick or stone masonry, cavity walls, tuff masonry, concrete masonry or aerated concrete blocks. Mapestop is a solvent-free concentrated micro-emulsion that must be diluted on site before using it with drinking water (1 part of Mapestop with 15-19 parts of water). Thanks to the reduced size of particles, from 20 to 60 nanometres, the Mapestop micro-emulsion can deeply penetrate into the damp masonry and, after the reaction with water, forms an efficient and durable watertight barrier. Mapestop must be injected in every single hole under the effect of gravity using special containers or a low pressure pump (max 1 bar) until the injected zone is completely saturated.
Consumption depending on the absorbency of the masonry. Indicatively 8-9 kg/m for a 40 cm thick wall.
Packaging 1 kg metal can with screw type lid; 180 kg drums.
