26May94 UK: TARGET PRACTICE - GUN-POINT AIMS AT CIVILS SECTOR.

Re-pointing and protective treatments specialist Gun-point is targeting the civils sector by expanding its operations to include a pressurised cementitious grouting to complement its injection pointing service.Using its own patented repointing equipment, Gun-point has already completed a number of civil engineering contracts.The most recent project is the refurbishment of Brinksway Bridge over the River Mersey at Stockport.This mid-19th century structure was widened in 1924 and so while the east side is made of sandstone ashlar blocks, the later built western side comprises five courses of masonry blocks with a main arch of brickwork and stone.Gun-point used its repointing techniques to stitch together the brickwork using 8 mm dia ribbed rods and Certigh anchor grout. A number of bricks was also replaced.About 3 tonnes of cementitious grout was injected under pressure to fill all voids and to stabilise the structure.Finally, 400 m of stonework and 200 m of brickwork were repointed. Using its mechanised raking machine, Gun-point removed old mortar to a depth of 35 mm before replacing it with a matching mortar injected with the company's patented pump and gun system.The company is now looking for more work in the civil engineering sector.Gun-point, 071-353 1759.
