Tuesday 4th April 2000

12.5m I.D. Smoothbore Shaft Rings were supplied to Dawson Wam to construct a Pumping Station in Pennyburn. The method shown here is "underpinning" where a 1m depth of ground is excavated, a segmental ring builtand grout pumped behind the ring. The process continues until the desired depth is reached.
