The injection pipes achieve high bursting pressures (> 100 bar), and can be supplied in various diameters. Injection pipes are used in a wide range of applications: as exhaust for injection inside anchors, if calibrated they can protect the anchor…
The load cells are instruments used to control the load applied to rods and anchors. This type of sensor is specially used during a project’s feasibility analysis, in load tests executed in laboratory or directly in the worksite. Sireg supplies resistive instruments with toroidal shape. Their body incorporates “strain gauges” giving a voltage or current…

Sireg Geotech designs and manufactures a wide range of plastic spacers for strand and bar anchors and for structural elements.
Spacers for bars, micropiles and corrugated ducts
In order to ensure a perfect centering of bars, micropiles and corrugated ducts within the drilling holes, Sireg Geotech produces a wide range of plastic spacers. The use of spacers can guarantee the right concrete cover around the bars, thus reducing the problems related to corrosion of metal products. The range includes both wrapping and…
GFRP D-Wall Spacer to be used to respect the minimum concrete cover design Designers specify a nominal cover based on a minimum cover plus an allowance for construction tolerances, the GFRP D-Wall Spacer is used for it. For the standard applications a minimum nominal concrete cover of 75mm (3″). It is recommended where the concrete…
Sireg Obturator Bags MPSP, 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/bentonite sheath can’t be executed. The product is characterized by the heavy duty seams which confer extreme resistance…
