TERRA Steel Pipe Ram TR 200mini Rams Foundation Piles for Piers

The Swiss contractor Boerlin Lavori Subacquei SA rams steel pipes as foundation piles for new piers into the lake ground. He uses a TERRA-HAMMER TR 200mini. In the past he used a conventional post ram, but its ramming energy had been too low. Company's owner Bruno Santomauro decided to purchase a steel pipe ram TERRAHAMMER TR 200mini due to its higher ramming energy and its easy handling.

Contractor Boerlin is specialized for construction sites under and over water on the Lago Maggiore and other lakes in the Canton Tessin.
