Until a few years ago, the application field of injections was limited only to very permeable soils or fractured rocks. Nowadays the use of sleeved grouting pipes (TAMpipe) with suitable grouting mixtures make possible to reach new goals. The grouting technique by means of sleeved grouting pipes offers various benefits such as: injections can be…
Sireg Geotech’s obturator bags, made in polypropylene geotextile, are used to seal the space between the Durvinil® TAM pipe and the borehole, when required in order to execute grouting treatments in fractured or permeable soils, when the cement sheath can’t be executed. They are used also in down-up drillings to prevent the cement or water…
Sireg Packers are compatible with all our grouting pipes and are supplied in the following types: double mechanical rigid packer (for TAM pipes up to 1″1/8) double mechanical flexible packer (for 1″ TAM pipe, ground anchor TAM pipe) double hydraulic packer (for TAM pipes 1″1/2, 2″ and more…) Sireg Geotech also supplies injection pumps, reels,…
1/2 Durotene® grouting pipes are used for post-grouting injection. They are supplied in customized rolls, with external manchettes or sleeves and U-corner.
PVC Durvinil® grouting pipes are used to perform injections of cement mixtures and resins as part of interventions of soil consolidation and waterproofing; they are also used in the excavation of tunnels, construction of dams, reinforcement of foundations. They are supplied in bars of length up to 6 meters, with external or internal sleeves, couplers…
Sireg Geotech’s Durvinil® SD system is formed by a Durvinil® sleeved grouting pipe dragged by a self-drilling steel head. The sleeved pipe is used to consolidate the soil through repetitive and selective high pressure grouting. The system is used to install the grouting pipe in loose soil or below the groundwater table, where it is…
DURVINIL BIO SYSTEM® injection pipes are made of compostable plastic, an innovation in the sector. They are used to execute injections in tunnel’s break-through areas in environmentally sensible situations. A the end of their life cycle, the pipe decomposes into simple materials that are absorbed by the soil.
