With the CVR C-Mix® pile walls, CVR developed a beautiful alternative in-house for traditional concrete pile walls. This innovative construction pit sheeting with soil mixing guarantees various advantages. For instance, less soil needs to be removed and no concrete needs to be supplied, which yields huge time savings. Moreover, this technique has a limited impact on the environment. The pile walls are sufficiently solid for a load-bearing function. They can be used as a definitive earth-retaining wall. The following diameters are possible: 430 mm, 530 mm, 630 mm and 830 mm.
Just as with a traditional secant pile wall, this pile wall consists of primary and secondary piles that overlap each other. Together, the sheeting piles form an underground, earth-retaining and water-inhibiting screen. The piles are perfectly suitable for use alongside structures that are prone to settlement. They are also perfect for installation in watery soils. Extra stability can be obtained using ground anchors.
As a member of ABEF (the Belgian Association of Foundation Contractors), CVR participated in meetings of the ‘soil mix’ working group of the BBRI. This working group forms the basis of the implementation sheet ‘soil mix pile walls’. We carry out our activities in accordance with this sheet.
