Concrete Scabbling  from Hydroblast

Selective Hydrodemolition removes the concrete only down to a preset ‘quality depth’, leaving a jagged or craggy surface that provides an extensive bonding area.

Jackhammers tend to leave a flatter surface, with fewer peaks and valleys and therefore less of a bonding area. This is especially critical when dealing with re surfacing.

Another advantage of hydrodemolition is that the Aqua Cutter typically removes damaged concrete several times faster than jackhammers – and users have found that it can be up to 25 times faster.

Directing high-velocity water jets against a surface to produce a destructive effect has long been successfully used for the high-speed cutting, or drilling of rocky materials including concrete.

Water-jet cutting has also proved to be a versatile technique in many other areas of industry, from early uses in cleaning inaccessible machine parts to modern specialist applications such as the precision cutting of intricate components.
