Joint Sealing and Resin Injection

Joint Sealing/Resin Injection:

Is available in two forms, grout injection or resin injection across to size ranges non-man-entry and man-entry.
In non-man-entry sizes the sealing process utilises specially designed packers that inflate but only at the ends. Once winched or pushed into place, using CCTV as a guide for the operator, to positon the centre of the packer over the joint/defect, the packer is inflated. Once the ends are sealed against the pipe wall grout or resin is passed into the central area of the packer under pressure to penetrate and fill the joint/defect. The packer remains in position whilst the grout/resin cures. The packer is then deflated and removed for use at another site, after cleaning. Any excess grout/resin can be removed and the pipe wall smoothed if necessary using a robotic grinder system and flushing with water.

In man-entry size pipes utilises an injection gun/lance that is utilised manually to fill defects that have been previously prepared (cleaned, shaped if necessary and roughened to provide a key surface for stability). Once filled any excess resin or grout is removed to provide a clean and smooth pipe surface. This can be achieved as a joint seal or for sealing defects within the pipe length itself.
