Mono-component, osmotic cement mortar based on hydraulic binders, modifying resins and superpozzolanic reactive fillers selected aggregates, for the preparation of adhesive mixtures that after curing, create a protective, waterproof, high-efficiency coating. OSMOCEM MR can be used for coatings, reconstructions and millimetric protections, finishing coats etc., in interventions of conservative restoration, waterproofing reinforced concrete structures, wall coverings, hydraulic works, extended exposed surfaces etc.

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 MR and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 14-16% of the weight of the bag. After mixing is completed wait a few minutes before applying.
To further improve the performance of the coating, insert a steel reinforcement mesh (wire 2 mm mesh and 5x5 cm) between layers.
- Finishing trowel
- Plastering machine
- Brick trowel
- Mixed walls (bricks and stones)
- Stone walls
- Rock 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, certified for drinking water. Very adhesive and easy to apply. It is a classic osmotic mix, efficient and cheap!
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.
