Cheaper and more flexible than carbon fiber, it is stronger than many metals, is non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include underground structures, bridge slabs, docks, swimming pools, and all the structures directly in contact with aggressive environments. 

What is a Glassfibre product?2019-11-21T15:56:32+00:00

Fiberglass is a common type of fiber-reinforced plastic (FRP) using glass fiber. The fibers are protected by a thermoset polymer matrix—most often based on thermosetting polymers such as polyester or vinylester, a thermoplastic resins.

Injection treatments through sleeved grouting pipes are required in the following cases:

    • Strengthening of foundations, which may be needed due to increased structural load, restoration of ancient buildings or the creation of underground spaces below them.
    • Large excavation pits and earthworks, in order to waterproof or consolidate, as an alternative or in addition to diaphragm walls and sheet piles.
    • Dam construction, which require waterproofing of foundation soil as well as of the abutments
    • Tunnel construction, where injections can be carried out sub horizontally (umbrella method), from road level in case of shallow tunnels, from a side tunnel in case of two parallel tunnels, from pilot tunnel (radial grouting method)
    • Ground anchors, where the sleeved grouting pipe allows to carry out first the primary injection followed by a high pressure injection, granting a perfect cementation of the anchors in the bond length.
    • Compensation grouting, which is carried out in order to create a strengthened / consolidated area between the foundations of existing building and the soil below, in order to avoid settlements due to excavation of tunnel or huge underground spaces.

What is TAM pipe?2019-11-21T16:32:46+00:00

A TAM pipe is smooth grouting tube with spaced ports (standard spacing is 330 or 500mm). These perforations are covered by rubber sleeves, also called “manchette”, which act as non-return valves.

With a double packer the injection can be carried out individually and repeatedly.
