Concrete scanning in Dorval for an office building renovation

Office buildings, often with post-tensioned slabs

Multi-storey office buildings often rest on suspended slabs, sometimes post-tensioned. A severed post-tension cable compromises the slab and leads to major repairs. Embedded electrical conduits, for their part, feed workstation clusters and floor outlets.

Original plans rarely show the current condition. After several tenants, the slab has already been drilled in many places, and new holes must fit between the existing elements.

What we locate before core drilling

• Post-tension cables and their path
• Rebar and wire mesh
• Embedded electrical and telecom conduits
• Old patched penetrations

A survey suited to an occupied building

Neighbouring floors often remain occupied during a renovation. The scan creates no noise or dust and can be done outside office hours. The PDF report documents each location, which makes the work of the building manager and the engineer easier.

Frequently asked questions

How do I know if my slab is post-tensioned? The structural drawings or the building manager can confirm it. Failing that, the scan helps distinguish post-tension cables from ordinary rebar, and the engineer makes the call.

Can you scan several floors in one visit? Yes, if access is coordinated. Send us the list of points per floor; the quote takes it into account.
