The granite paving through the Peace Gardens in Sheffield has been refurbished for Sheffield City Council using GftK's vdw 850 Paving Joint Mortar from NCC Streetscape.
The highly durable granite was becoming loose and subject to damage due to the far less durable cement based jointing mortars used originally and for earlier repairs. Whilst "˜traditional' these are all highly sensitive to water, mixing and exposure to frost resulting in typical cracking and loss of strength problems.
The Council's Engineers and their Contractor found the ideal solution was the unique, epoxy resin bound sand based, vdw 850 Paving joint Mortar from NCC Streetscape. This also enabled all of the work to be successfully completed without having to completely close any areas of the popular commuter routes through the gardens.
The areas were high pressure water jet cleaned, any loose stone setts re-fixed and then the joints were simply wet-slurry pointed with the vdw 850 jointing mortar, which self-compacts into the joints. The surface was rinsed, dry brushed-off and within a short period of time reopened – also with no delays for cold or wet weather.
