WATERBLOCK - Waterproofing for Basements and Tanks

WATERBLOCK is an inorganic brushable waterproofing mortar in powder form, which is simply mixed with water. It contains cement, silicate aggregates and chemical additives, creating waterproofing compounds of calcium and significantly improves bonding and workability.

After hardening, WATERBLOCK creates a totally rigid and waterproofing coating. If for any reason the substrate is expected to create cracks, WATERBLOCK must be elastified by using VIMAFLEX, which is a liquid elastifying agent for mortars.
Totally suitable for constant contact with water
Offers limitless protection from water, because it is an inorganic material that does not age.
The layer that it forms is total waterproofing against hydrostatic pressure, in accordance with DIN 1048
Although water impermeable, it is vapour permeable, allowing the building elements to breathe.
Suitable for potable water tanks, because it does not contain toxic substances.

Applications

  • Basements – water tanks – swimming pools – drains – flower stands – terrace gardens – sewage pits – biological treatment tanks – tunnels – damp places in general (under tiles).
  • Ideal for waterproofing in cases of simple dampness and even water under pressure.
  • Can be used for waterproofing basements on the internal side (also at a later stage), because it can withstand negative pressures of water due to high bonding to substrate.
  • Suitable for waterproofing external walls when applied under the plaster (e.g. near the ground surface).
  • In combination with the elastifying agent VIMAFLEX and fiberglass mesh or chapped mat as reinforcement it can be applied for waterproofing terraces either covered (in grey color) or exposed to the sun (in white color).
