Elastotex
Elastotex is endowed with exceptional chemical inertness, laboratory tests have shown that it can sustain prolonged contact for 7 days at 20 °C with the following substances without problems: hydrochloric acid at 3%, sulphuric acid at 35 %, citric acid at 100 g/l, lactic acid at 5%, potassium hydroxide at 3% and 20%, sodium hypochlorite at 0.3 g/l, salt water at 20 g/l.
Fields of application
Waterproof sealing of expansion joints, including large ones, subject to considerable work movements, and of natural joints and fissures, also in conditions of hydraulic counter-thrust, in tunnels, silos, tanks, pools, basements, roofing, prefabricated coverings, road joints and hydraulic works in general.
Allowed supports
Concrete
Prefabricated concrete
Preparation of supports
The application surfaces should be clean, free of incrustations, dust and non-adhering parts, carefully roughened.
Mode of use
Mix the epoxy resin Syntech AS 21 thoroughly in the pre-determined amount as required. Spread the epoxy adhesive prepared as described above, on the sides of the joint to be waterproofed by toothed adhesive spreader, kept constantly clean, taking care to obtain uniformity of the thickness applied that must not be less than 2 mm. Unroll and apply the Elastotex strap, on the fresh adhesive spread, pressing it against the resin, stretching the ends by hand, taking care to avoid wrinkling and air bubbles, until the underlying resin totally impregnates the fabric at the side of the strap. Apply with a metal filling knife a second layer (at least 2 mm) of Syntech AS 21 adhesive on the fabric at the edges of the strap, already impregnated, in order to protect it permanently from accidental damage and to obtain certain monolithicity of the end to the support.
For the joint between two adjacent straps, weld the end flaps for overlap and solder them using a special hot air welding machine. For additional security of the seal, a small layer of Syntech AS 21 should be applied on the heated flaps.
The final system resistances will be reached after about 7 days after laying, but already after 24 hours at 20°C, values equal to 60-70% of the final performances can be obtained. In any case the performance after 24 hours will be much greater than those of a high quality concrete.
