GEOSEAL A1 is a premix in powder form, based on high-strength hydraulic binders, water-repellent additives, powdered resins and selected aggregates. It comes as a powder for mixing with water at the time of use.
GEOSEAL A1 is reactive with respect to calcium hydroxide, forming stable and insoluble compounds.
GEOSEAL A1 provides the perfect supplement to the substrate, creating an insoluble crystal formation which blocks the capillaries by osmosis.
PROBLEM: WATERPROOFING UNDERGROUND SPACES
Water from infiltrations, unconfined aquifer or normal humidity formed in the land where the foundations lay is the main source of degradation and thus unaccessibly to underground or partially underground spaces. In addition to the high humidity rate, that makes the spaces unusable, the salts dissolved in the water cause the plaster to detach. In the most serious cases, in the presence of unconfined aquifer, the water pushed by hydrostatic pressure tends to reach the same external level inside of the space, through cracks or empty capillaries.
Application Fields:
Internal and External Walls of Tanks, Water containers, and to waterproof new or degraded concrete items of channels, pipes, tunnels
Advantages:
- The ease of application makes the intervention inexpensive and quick.
- High penetration and adhesion to the support.
- It keeps the permeability to water vapour.
- High resistance to pressurised water.
