Retention Systems Drilled, pushed, vibrated or driven support systems (steel sheeting, soldier piles and lagging, tangent pile walls) cantilevered, braced or tied-back, installed in all types of soil to provide horizontal and vertical restraint of adjacent property during excavation and construction of below grade facilities.
Vibro-Compaction A site improvement technique for granular material, Vibro- Compaction uses proprietary designed probe-type vibrators to improve the density of soils to depths of up to 40 meters. VibroCompaction increases bearing capacity mainly to enable the use of shallowfooting construction, reduce settlements and mitigates liquefaction potential in seismic areas.
