Cement compound for immediately stopping the infiltration of water

Code: OSM.0087

Components: 1

Appearance: Powder

Cement compound for instantaneously stopping water leaks in underground rooms or above-ground structures, even in the presence of negative thrust pressure. Based on rapid hardening and high resistance hydraulic binders of ultrafine quartz aggregates, shrinkage compensators, micronized hydrophobic products and specific additives for the regulation of rheology. It does not contain chlorides. Mixed with water it gives rise to a mixture of thixotropic plastic consistency, easily applied even vertically, which hardens in 30" - 60", adhering perfectly to the roughened support.

Approximately 17 kg/m² of OSMOCEM QUICK for every centimetre of thickness to be implemented (approximately 1700 kg per cubic metre).

Use fields

Immediate stop of water infiltrations in building structures: basins, tanks, cellars, lift shafts, drains, underground masonry, etc. Examples of use: waterproof sealing of cracks and holes, waterproof repair before the addition of concrete, waterproofing systems made in combination with FLEXSEAL 300 hydro-expansive sealant and waterproof mortars of the OSMOCEM line.

Preparation of supports

Thoroughly clean the contact surfaces. In the case of cracks, discontinuities, cavities, etc. preliminarily prepare application sections countersinking towards the inside of the masonry, creating a "dovetail" shape (in order to facilitate the hydraulic sealing of the intervention). Remove any detached residual material from the prepared site, by means of pressure washing and jets of compressed air. Any interventions on temporarily dry surfaces require wetting of the support to saturation.

Use method

Mix with water, if possible at a temperature not less than 20°C, no more than 250-300 cc per kg of product. The product reacts immediately and it is very quick, therefore mix from time to time the quantities of product strictly necessary and immediately applicable.
Apply the product on site by hand exclusively and immediately after mixing the product with water while wearing protective rubber gloves. Press the mixed product firmly into the slot or hole and hold this pressure until the setting is complete (approx. 120 – 180 seconds).
In case of multiple leaks, start the application of OSMOCEM QUICK from the higher water leaks. Where necessary, in case of pressure infiltrations, proceed with the installation of drainage with a plastic tube, with small diameter, initially sealing sections adjacent to the drainage and then, once you stop the infiltration, sealing the drainage itself.

Application methods

- Apply by hand

- Spatula

Tool cleaning

- Water

Permitted supports

- Concrete

- Bricks

- Mixed walls (bricks and stones)

- Stone walls

- Rock walls

Warnings, precautions and Ecology

OSMOCEM QUICK contains cement which, in contact with the sweat of the body, causes an irritant alkaline reaction and allergic reactions in predisposed subjects: wear wraparound protective gloves in thick rubber and use the usual precautions for handling of cement-based products; in case of contact wash with plenty of water. Do not remix the product in the hardening phase and do not float it when it has just been laid.
It is always essential to carry out preliminary tests to check the appropriateness of the product, depending on specific requirements.
