ATP produces a large number of different GRP pipes for the consolidation of the face  of excavation.

The high tensile longitudinal strength , higher than steel, coupled with  the low resilience , make this product very advantageous when it must later be demolished with the hammer drill or poin mill.

The pipes are available in several diameters, with different thickness and different resisting section, as well as several levels of burst resistance, in order to be able to cope with any type of soils.
