Ringseal L19
The hydro-expansive capacity of RINGSEAL L19 has been tested in the laboratory with three different types of water: demineralised water, salt water and water with strongly basic Ph (to simulate the conditions in contact with the concrete). The expansion tests showed a change in volume ranging from a minimum of about 200% (three times the initial volume) in the case of salt water to a maximum in excess of 900% in the case of demineralised water.
In the standard version, the seal RINGSEAL L19 is sized for the usual measures of the blade caisson spacers, normally used in the construction industry: in this case with a width of about 20 mm, in the version straight/flat or "twisted" (designed to minimise the propensity to form deformities during the pouring of the concrete in the formwork).
Fields of application
Subterranean construction of concrete by formwork in wood, where the wall is in direct contact with the ground and where there is the presence of waterproofing layers external to the masonry itself: basements, cellars, underground garages, underground environments and basements, etc.
Allowed supports
Concrete
Metallic spacers for wooden formworks
Mode of use
Place the hydro-expansive seal RINGSEAL L19 with the appropriate dilating pliers in central position with respect to the length of the blade caisson spacers (one seal for each spacer). Build the planned formwork using the metal spacer for wooden formworks thus prepared and proceed with the usual operations of casting the concrete.
Application methods
Apply by hand
Dilating pliers
Consumption
No. 1 Ringseal L19 gasket for each "blade" formwork spacer (average 6 - 8 pieces per square metre for wooden formworks of 2 x 0.5 metres).
