Flexible Spiral Tube

A material with a very high radial stiffness that is well suited for usage as a void forming in concrete constructions. Furthermore, it is employed as culverts and forms for concrete piles, plinths, and columns. Reduce the cross section area and, consequently, the weight of the structure by using GP Spira-VOID tubes as void formers. With the weight reduction coming to about 40%, foundation, wall, and slab construction will benefit.
