Block work Method Statement

Blockwork walls are typically constructed in wet sites, and the underwater section is constructed from plain concrete blocks with an in-situ concrete cap for the upper section of the structure. The precast blocks are typically founded on a stone bed and terminate in the tidal zone.

Blockwork walls

Blockwork walls are typically constructed in wet sites, and the underwater section is constructed from mass (plain) concrete blocks with an in-situ concrete cap for the upper section of the structure. The precast blocks are typically founded on a stone bed and terminate in the tidal zone. The cap is constructed in-situ, working tidally in the dry, and it is used to tie the block stacks together and spread the berthing and mooring loads. The horizontal and vertical placing tolerances of the block stacks is typically larger than that normally used for in-situ works, and the in-situ cap serves to accommodate the variation in block position and to create an accurate edge.
