Sheet piling being driven on each side of the lock. This is about a third of the number a piles which
will be required.
A closeup of the hydraulically driven head. This method of driving
is much quieter than older methods which allowed a heavy weight to drop onto a cap placed on the top edge of the pile.

A massive hole is now being dug between the rows of sheet piling. Picture taken on June 30, 2005.
The depth of the excavation can be judged from the height of the man.
It is 2.7m (8ft 11in) deep, 7.7m (22ft 3in) wide between piles and 41.9m (137ft 6in) long
Mike checks the depth. The excavation is being made to tight tolerances. Too deep
and more concrete has to be used. Too shallow and the required final depth of the lock will not be met.
The bottom of the excavation is to be covered with a 'blinding' layer of concrete 50 to 75mm thick.
Blinding is a layer of concrete made to a weak mix on which all the other structures stand. To avoid problems it
has to be as level and flat as possible
July 6 and the excavation for the lock is complete. The contractors and their machinery have left the site. (Photo: Richard Elmsley)
Strips of blinding concrete are being placed along the edges (shown on right of picture) to act as a guide for
blinding the main area. As can be seen, the weather has not helped leaving the work area very muddy. The levels for the blinding layer have to be established with high
accuracy, hence the need to frequently check as shown here. (Photo: Richard Elmsley)

The blinding pour well underway with at least half the surface already
tamped and levelled. By mid afternoon the blinding was complete. The site is now ready for the work camp to begin
on July 9. (Photo: Eric Walker)
