Chasing is a method of cutting neat channels in concrete or masonry structures. The chase is formed using a hand held electric grinder with diamond blades.
A vacuum collects the dust before it escapes into the surrounding evironment. Two slots are cut to a precise width and depth and the concrete / masonry is removed using a hammer drill or small breaker.
The technique is quick and relatively dust free and is used to cut chases for conduits and pipework in walls, floors and ceilings. It is suitable for all types of brickwork and blockwork.
