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.
