Cement compound for the preparation, with the sole addition of water, of a waterproofing osmotic coating that can create horizontal and vertical barriers, also suitable in conditions of negative hydrostatic thrust vis-à-vis water permeation in the buildings. Typical uses include waterproofing underground rooms, elevator compartments, garages, basements, tanks, etc.

The action of the active components and of the adhesion promoters of OSMOCEM N, saturated by the reaction the support capillaries, forming a complex system of gel and stable crystals, which results in the best sealing, effective even in conditions of negative hydrostatic thrust, without hindering the breathability of the walls.
OSMOCEM N is compatible for food substances: is certified as suitable for the containment of foodstuffs and drinking water (Certificate no. 02/2010 Laboratorio Analysis Service di Settimo di Pescantina - VR).
Approximately 1.7 kg/m² of OSMOCEM N for each millimetre of thickness to be made.
Waterproofing rigid structures and masonry walls underground, buried or in any case subject to water permeation: lift wells, basements, tanks, pipes, tunnels, garages, bridges, reservoirs, areas containing food, etc. in conditions of positive and negative hydrostatic thrust provided they are sufficiently porous and absorbent and free from any waterproofing and / or water-repellent surface treatment, whether chemical (siloxanes, epoxies, polyurethanes, etc.) or natural (wax-up).
Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., water repellent treatments in general, etc. conveniently saturated with water until they reach the condition "saturated with dry surface".
Pour about 2/3 of the mixing water into the mixer, add OSMOCEM N and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 19-20% (for interventions in the form of a spatula) or 21-22% (for interventions using a brush with long bristles). After mixing is completed wait a few minutes before applying. If applied by brush, roll out two or more crossed coats.
Although it is not a specific product for finishing thick coats, it can still be used for these purposes. In these cases, it is appropriate to use a fibreglass mesh ARMAGLASS 160.
- Finishing trowel
- Plastering machine
- Prefabricated concrete
- Mixed walls (bricks and stones)
- Stone walls

It is always essential to carry out preliminary tests to verify the appropriateness of the product, depending on specific requirements.
Do not apply in case of direct exposure to sunlight and cure the protection and moist hardening.
Do not apply on little or non-porous substrates or previously coated with water-repellent treatments in general, if not after appropriate roughening by bush hammers, sanders and equipment suitable for preparatory treatments of substrates, or after appropriate treatment with suitable polymeric primers.
Monocomponent, osmotic cement mainly used to fill and waterproof the cavities in a concrete wall having removed the protruding part (excess) of the formwork spacers.
Two-component, osmotic cement, certified for drinking water and EN-14891. Moderately deformable, highly resistant and adhesive, it is a multi-use product. Resists traffic, UV rays, ideal for reinforced finishing coats. Azichem's bestseller!
Composed of flexible, two-component cement, certified for drinking water. Specifically for the waterproofing of terraces and balconies, applicable both on the screed and old floors.
Hard, monocomponent, osmotic cement. Highly resistant and adhesive. Specifically for the construction of reinforced, impermeable and thick grout, both in thrust and counter-thrust.
Two-component, osmotic cement, slightly deformable. To use thick, both in thrust and counter-thrust. It is the evolution of the OSMOCEM MR, easier to apply and more adhesive. Recommended!
Hard, monocomponent, osmotic cement with a natural hydraulic lime base. It is an ideal product for waterproofing in positive thrust, in the restoration and recovery of old buildings.
Rigid monocomponent osmotic cement with reactive crystallizing reaction. Specific for the construction of waterproof, thick coatings, both in thrust and in counterthrust, of products with liquid contents at pH 4.5.
