NPS® Dia sheet piling truss is made of structural steel (UNI EN 10025-2), according to the patent filed. Finalised with the construction of retaining walls, support walls and NPS® Diaphragms, NPS® Dia reinforces and contains temporary works destined for the realisation of infrastructure.
NPS® Dia is applied to containing walls with CSM technology ("Cutter Soil Mixing”),which foreseen the remixing of soil at the site with additional water and a binding agent, which could be cement or bentonite, and a potential insufflation of air.
The monolithic design of the work further guarantees the elimination of torsion instability during the installation phase compared to metal profile solutions.

For all tasks that require soil containment during the digging phase, NPS® Dia is a truss panel made of steel which is rendered safe with one operation, quick and precise reinforcement insertion in the reinforced concrete NPS® Diaphragms.
