Dredging Half a Moat Using Portadams

AWM were contracted to dredge half of the moat around a house near Brighton. Two Water filled portadams were used in order to de-water one half with fish caught as the water level was lowered and moved to the 'wet side' of the dams.

One of the two portadams is positioned ready to roll out across the moat.

One of the portadams from the dry side. Note the way it moulds itself to the bed of the moat. The pipe is from a 150mm diesel pump removing the spring water that feeds the moat.
