– Placed more than 100 tons of stone rip-rap to stabilize the embankment.

– Placed and finished 625 square feet of concrete within an active concrete plant.

CUSTOM SOLUTIONS

– When a high-powered vacuum truck could not clean out all of the soil in the sheet enclosures, Cashman collected the soil during sheet driving,

– Cashman designed a custom airlift powerful enough to get 50 feet deep, yet small enough to fit in the 3-inch gap in the enclosure.
