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 structures out of the ground, even in the presence of moderate negative thrust pressure. Based on rapid hardening and high resistance hydraulic binders and special additives, it hardens in 30" - 60", stopping the water flow.

Use fields

Immediate stop to water infiltration in building structures: tubs, tanks, cellars, elevator shafts, pipes, masonry underground etc.

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, according to the "dovetail" shape (in order to facilitate the hydraulic sealing of the intervention).

Use method

Mix with water, if possible at a temperature not less than 20 °C, no more than 250 cc per kg of product. The product reacts immediately and it is very quick, then 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.

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

It is a caustic product: wear enveloping thick rubber protective gloves; in case of contact, wash with copious amounts of water. Do not stir 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.
