Reusable mechanical packers

Reusable packers for 28–135 mm boreholes

Compression packer whose rubber expands under mechanical compression. The reusable version is recovered from the borehole after grouting and can be used again and again, while the check valve stops the grout from flowing back out. It is installed by screwing it on with a dedicated packer nozzle and is particularly suited to tunnelling applications.
