Cementitious sealing mortar for concrete and masonry, containing special additives that protect concrete against water penetration and penetration.

Features

• one-component
• ready to use after adding water
• permeable to water vapor
• frost-resistant
• approved for direct contact with water intended for human consumption
• good adhesion to many substrates, e.g. concrete, cement mortars, stone, etc. surfactants reduce capillary water penetration
• significantly reduced ingress of water
• mechanical or manual application

Application

• sealing horizontal and vertical surfaces of concrete structures
• protection of concrete structures against water penetration (positive and negative pressure), such as drinking water tanks, bathrooms, swimming pools, foundation insulation in heavily watered ground, anti-moisture insulation, underground structures
