Hydro Coat Osmocem is a mortar with crystallizing osmotic action for water proofing concrete and masonry work against rising and descending damp. It is a single component, thixotropic and resistant to positive and negative hydraulic pressures. Hydro Coat Osmocem reacts with moisture and creates a continuous barrier of insoluble crystals. The capillaries are permanently blocked to the passage of water. However, vapour may pass through allowing structure to breathe. Rate and penetration of minerals depends on presence of moisture, free lime and density of concrete.
Areas of Application
Foundations, hoistway pits Underground environments and car parks Exterior foundation walls, also with negative hydrostatic thrust Irrigation channels, drains, tubs Water (also drinking water) collection tanks and reservoirs Tunnels, galleries, siphons and dams- viaducts and bridges Fresh concrete castings or prefabricated concrete, structural plasters
Features & Benefits
Single-component, low environmental impact Thixotropic, can be sprayed or applied with a trowel to vertical and horizontal surfaces Excellent protection of concrete structures, safeguarding against the ingress of Carbon dioxide, chlorides, sulphates, from the action of water containing aggressive carbon dioxide and from freeze/thaw cycles Resistant to environmental chemical aggression and suitable for all exposure classes in accordance with Environment. Waterproofing product for underground concrete structures under positive and negative thrust / preassure. Certified as suitable for the containment of drinking water Resistant to abrasion.
Method of Application
The substrate must be perfectly cured, free from hygrometric shrinkage, solid (i.e. free of weak or easily removable parts) and free from oil, grease and paint.
Check that the concrete contains no traces of parting compound. The most suitable cleaning methods are sandblasting, shot peening or washing with pressurised water.
When working on weakened parts, when parts of the substrate are missing and also in the case of gravel beds, the substrate must be restored with Dubond Ducem before application, the substrates must be wet well but must not include any stagnant water In waterproofing operations for exterior foundation walls and underground structures.
Preparation of substrates
Prepare Hydro Coat Osmocem by mixing 10 kg of powder with approximately 3-4 litres of clean water according to the chosen type of application (spreader or brush). Mix with a low-rev, stirring device for approximately 2 minutes until a mixture with a fluid and homogenous consistency is obtained . Pour almost all of the water required into a clean container and gradually add the powder during the mixing operation until the desired consistency is obtained. Leave the mixture to rest for approximately 5 minutes to allow for complete hydration of the micro-components and mix again for approximately 20 seconds before use.
Precautions & Limitations
Do not use Hydro coat Osmocem on rough terraces, non-structural substrates, flexible substrates, walls of gypsum, plasterboard or gypsum-base plasters.
Health & Safety Precautions :Use mask, nose cover and hand gloves during application.Clean hands with soap water after application. Avoid contact with skin / eyes. In case of unlikely contact with eyes, rinse immediately with plenty of clean water, then cleanse with soap and lukewarm water and seek medical advice. Do not use solvent to clean the contacted area. In case of unlikely swallowing, seek medical attention immediately. Do not induce vomiting.
