CORRUGATED SLEEVED PIPES

The corrugated sleeved pipes have been conceived in order to realize the bond length of tendons / anchors through the use of selective grouting. The corrugated pipe has the sleeves mounted according to the scheme proposed by the customer who, once inserted the pipe into the ground, will be able to carry out a selective and repetitive grouting in the part of the soil to be treated. In this way a real selective grouting can be carried out, furthermore it can be checked the volume of grouting material to be injected and in case of need, the treatment can be repeated.
