The Christmas period 2004 was a busy time for the team working on the Holmethorpe Underbridge, near Redhill in Surrey. After 4 months of hectic preparation the portal structure was inserted into a railway embankment over a 101h possession period which started late on Christmas Eve 2004.
The complete 1700t structure, including the wing walls and foundations, was cast offline during the run up to Christmas, but this still left removal of the track and embankment, the moving of the underbridge into position, the backfilling and the reinstatement of the permanent way to be completed in the short time available.
The construction was undertaken by Hochtief (UK) Construction Ltd on behalf of Linden Homes, with the completed structure becoming a Network Rail asset. The design of the underbridge structure, in its permanent condition and during transportation, was done by Tony Gee and Partners from its Cobham office in Surrey.

Unreinforced solid dense concrete block walls constructed using thin joint technology

The transverse lateral load capacity of masonry built using solid dense concrete blocks with thin joint mortar is up to 4.0 times that of similar blockwork constructed using conventional mortar. Both the mortar properties and the constituents of the parent material forming the block alter the joint strength resulting in enhancements to tensile flexural bond strength. Testing on two block types and one mortar has been undertaken and verifies the trend. Essentially when thin joint technology is employed, in conjunction with solid dense concrete blocks, the masonry behaves more as a concrete plate than conventional blockwork. A. N.
