OSMOSEAL

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.
The lack of suitable waterproofing or defects in the same, in addition to causing significant damage, always makes subsequent curative treatments difficult and expensive.Therefore, it is fundamental to prevent and protect these structures from possible water
penetration with a waterproof cement coating particularly resistant to aggressive agents,
impacts and abrasions during backfilling. OSMOSEAL 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.
OSMOSEAL is reactive with respect to calcium hydroxide, forming stable and insoluble compounds.
OSMOSEAL provides the perfect supplement to the substrate, creating an insoluble crystal formation which blocks the capillaries by
OSMOSIS.
The special additives which it contains form, with the cement, a double layer which is impermeable to water, maintaining a crystallising effect (osmotic healing) over time.
