Tipperary County Council - Clonmel Town Flood Wall Joint Seal Replacement River Suir (Clonmel) Drainage Scheme - Flood Wall Joint Seal Replacement. In order to address long-term issues of flooding in Clonmel, the Office of Public Works (OPW) commissioned a study of the catchment area and to develop sustainable options to address flood risk in the town and the surrounding areas. The overall flood defence scheme comprised of: ● 3.8 km of flood walls ● 3.5 km of embankments ● 850 m of demountable defences ● 5.9km of storm water sewers ● 12 pumping stations ● 2 fish passes ● the replacement of three bridges ● strengthening / widening of a further two Bridges. Work on the scheme was completed in 2013. As part of the construction of new flood walls and the modification of existing quay walls, joints were constructed utilising a two-part immersible biodegradation resistant/UV resistant polysulphide sealant on both sides of the wall. There are visible signs of these seals reaching the end of their operational life where the sealant has shown signs of shrinkage and de-bonded from the concrete. The scope of this contract includes the replacement of the joint sealant at all joints located along the New and Old Quay flood walls.
