Valve packers are intended for horizontal and vertical waterproofing injections in non-drivable soils. Bundling of valve packers allows injections at different depths in only on borehole.
Bore holes Ø 80 to 150 mm are made to the required depth. The bore pipe is filled with a sheathing compound consisting of water, cement and bentonite and is removed. Now the valve packer is installed by means of the injection tube. The required positioning depth determines the length of the injection tube. The injection pressure breaks the sheathing compound and the injection material is injected into the soil. By using several bundled valve packers each packer is injected separately.
