Wall Sawing
Wall Sawing is the process of cutting openings in concrete walls using a circular blade on a track mounted machine. Typically used to cut doors, vents and window openings.
Ground Penetrating Radar (GPR) is a safe and accurate non-destructive method to determine the presence of any embedded objects.
Concrete scanning is the use of Ground Penetrating Radar (GPR) and other equipment to detect materials or voids within a concrete slab.
GPR scanning can detect slab depth, rebar presence and details, post-tension cables, electrical conduit, and voids. It can also be used for structural review including concrete slab measurements and rebar spacing.
Concrete should be scanned before any destructive work is performed to prevent damage to items such as rebar, embedded services (electrical, plumbing) and/or PT cables. Destructive work can include coring, drilling, cutting, and other activities.
Concrete scanning enables you to visualize major structural components within concrete. Markings allow you to avoid these areas when performing invasive work, preventing damage to the concrete structure. Damage to post-tension cables can be extremely dangerous, potentially causing immediate structural failure and injuring or killing those on site. Damage to electrical services within the concrete can cause electrocution or death.
Yes, GPR equipment is regularly used to scan for the location of rebar in concrete columns and walls. It can also be used to scan the underside of a floor to mark out the reinforcing steel and any embedded conduits.
