A GRAFF concrete saw at work on the floor of stall 12.

Looking East from Stall 14.

After cutting, the loose blocks of floor slab are pried out by hand.

 A cut block with no support will drop, occasionally jamming the saw blade as has happened here.

The end result: The floor slab blocks are removed leaving the foundation "grade beams" visible.

An interesting intersection of grade beams below the floor slab, unseen since 1929!

The original roundhouse roof drainage ran through the service pits. Since this pit (12) is to be filled in, new pipes are fitted to carry the water.

Additional drainage pipes are from floor drainage troughs below the beer tanks.

Removable weak-concrete fill is placed in the pit and re-bar laid on top for the new concrete cap.

 An unusual sight - a four-axle, 12 cubic yard transit mixer traverses the park.

 A Schwing concrete pump was used to deliver the concrete into the roundhouse from the delivery trucks.

The finished cap concrete is flush with the original floor.

Two days later the concrete has set and the floor is swept in preparation for blast cleaning ready for the new top finish.

Iron-pellet blast cleaning and vacuuming leaves the floor ready for the epoxy top coat. Dirty old floor is on the right, freshly cleaned on the left.

A clear  primer/sealer is applied by hand roller.

The red-brick coloured epoxy top coat is 3/8" thick and applied by the STONHARD company who also manufacture the product.
