|Location:||Cleator Moor, Nr. Whitehaven|
Where the B5295 crosses the River Keekle, which links Cleator Moor with the port of Whitehaven, there are two separate masonry arches, connected by sandstone walls, with one spanning the river and the other over a public footpath.
As this part of Cumbria is very prone to flooding the second arch provides a useful outlet for flood water but was suffering from circumferential cracking of the barrel soffit and crown. This was as a direct result of differential movement between the stiff parapet sections and the masonry barrel arch.
The arch, which is 10.8m wide with a 7.3m span, is constructed from squared, random rubble, snecked sandstone masonry. Engineers from Cumbria County Council had originally considered stitching the crack with ties rods and external pattress plates until Helifix suggested its SockFix grouted anchors as a far better aesthetic solution.
Council engineers designed the repair to stabilise the cracked barrel soffit using a mixture of 2m, 2.5m and 3m SockFix grouted anchors installed through the voussoirs on both sides of the arch.
With the fully concealed repair completed, structural integrity was restored to the arch with its visual appearance unaffected.
