Use fields

Stop the infiltration of pressurised water in buildings by targeted injection of hydro-expansive polyurethane resins SYNTECH H.A.G. or fluid epoxy resins (SYNTECH IC 55).

Preparation of supports

The surfaces of application should be clean and free of any soiling, crumbling and non-adhering parts, powder, mosses, moulds, etc...

Drill holes at the predetermined injection points. The injection holes will first be made with an 8-10 mm drill bit, which should reached the required and intended depth within the wall body. Subsequently, only for the last superficial 10 cm, a second drilling will be performed in the same hole, with a 18 mm drill bit to create the seat where the rubber tip of the injector will be inserted.

Use method

Insert SYNTECH H.A.G. INIETTORE 170 in the intended holes. Screw the end portion of the injector with a suitable key. Screwing the injector will compress the rubber located on its tip, making it swell and thus creating the required mechanical and hydraulic seal. At this point, the injector is ready to be used.

Ensure the seal of the injectors placed in the supports is secure. Given the high injection pressures reached by the pumps, in the case of injectors not positioned securely and correctly there is a real risk that they might come out at high speed from their seat (with the risk of injury to the operators!).

Carefully study the positioning of the injectors near the masonry discontinuities to be injected. Bad positioning, too close to the crack to be filled, can cause the breaking of the support itself under the pressure of the pump.
