DESCRIPTION
They were designed to solve problems during grouting. A hydraulic manual pump starts a hydraulic piston and compresses two special elastomer elements attached to steel rings with the same diameter. While stretched , rubber optimizes the leaktightness inside the micropiles or PVC tubes.
The packer may be used both as a single one or a double one by changing the position of rubbers.
Additionally, the rubbers are interchangeable so it is possible to use the same packer in tubes of different diameters.
