Pressurized water leaks and infiltrations in general, which can manifest themselves to a greater or lesser extent in innumerable situations and building structures, give rise to real emergencies that require rapid, practically immediate and, at the same time, lasting solutions.
Unfortunately sometimes, not to say often, water infiltrations can be difficult to solve: difficulties in reaching the area where the possible defect was found, or can be the path of water infiltration is divided into various diversified branches, or many other circumstances. In these particular cases the traditional waterproofing systems and techniques are not able to fully solve the problem, making impossible to obtain complete and satisfactory results. The precise knowledge of the behavior of special water-reactive polyurethane resins and the technical specifications of these products, accompanied by the concrete experience gained in the field, allows the most suitable intervention protocol to be adopted in all circumstances, in order to gradate and distribute the necessary pots to seal by injection, after careful preparation of the areas of intervention, the leakage of water.
These special resins, produced and distributed by Azichem since 1987 in thousands of applications, are the SYNTECH HAG FLEX and SYNTECH HAG ECO
IMMEDIATE STOP OF
The SYNTECH HAG consists of creating, by the injection of hydro-expansive polyurethane resins, an impermeable barrier in the cracked structure, shelled by “crawl” in the concrete or by simple infiltration. Polyurethane resins are supplied in two formulations of different expansion capacity. They are injected into the identified points, detected by diversified injection schemes and appropriate to the different contexts, through specific “flat-head” metal injectors up to definitively blocking all water access routes. Water infiltration from cracks in negative pressure, from formwork spacers, from connections between floor and wall, from rigid or expansion joints, from gravel nests, from passing pipes, from predalles polystyrene floors, will no longer be a problem.
