In concrete products in general and in those placed underground or in the vicinity of aquifers in particular, a constructive detail, moreover indispensable, such as the formwork spacers consisting of steel blades usually 19 mm wide, constitutes a dangerous element of discontinuity, permeation and infiltration.
In fact, the water is located at the concrete-spacer interface, a place for differential shrinkage and frequent crawl spaces, an easy way of access and infiltration capable of seriously affecting the hermetic seal of the building.
The particular characteristics of the Azichem hydro-expansive rubbers, allow to extend the protection to this real constructive “Achilles heel”, through water-tight devices, both easy to make and economically advantageous, consisting of organically functional systems: the RINGSEAL L19 hydro-expansive seals .
The installation of the gaskets on the spacers is entrusted to a tool specifically designed to allow an easy assembly of the same RINGSEAL PINZA K4.
RINGSEAL L19
RINGSEAL L19 is a rectangular gasket with a central hole of 19 mm x 2 mm, made with a special hydro-expansive rubber that reacts in contact with water by increasing its initial volume. RINGSEAL L19, used in combination with a normal metal spacer for moulds made of wood ("blade"), hermetically seals the discontinuities which could easily settle in the concrete due to the presence of the spacers; these discontinuities could in many cases pass from one side of the masonry to the other, and which then might seriously compromise the watertightness of the masonry itself.
