The Council is procuring a contractor to undertake masonry

repairs and sediment removal works at Cammock Bridge,

located at 341541E/552725N, south of Carlisle. The bridge

carries the C1041 Brisco Road over Cammock Beck.

The purpose of the project is to;

• Undertake masonry repairs throughout the structure
• Remove sediment built up on the invert

These works are required to maintain the structural integrity

and hydraulic performance of the bridge.

The contractor shall undertake masonry repairs throughout

the entirety of the structure, including but not limited to

• Replacement of all spalled, missing or severely

deteriorated stones

• Repointing of all loose, open or defective joints

All below water elements should be repointed using

Rockbond underwater repair mortar or an alternative

accepted equivalent. Any alternative product must be

submitted for acceptance prior to use.

The mortar mix for above water repairs shall be 1:1:6

(Cement: NHL3.5: Sand). A well graded sharp sand shall be

used, and the mortar shall match the surrounding stonework

as closely as practicably as possible in terms of colour, texture

and appearance.

All new stone should match the existing as closely as possible

in terms of type, colour, texture, size and finish. All works shall

be carried out with appropriate care to preserve the character

and integrity of the existing structure.
