Concrete Delamination & Deck Condition Survey
Delamination — where the concrete cover separates from the reinforcement, usually from corrosion — is the early stage of spalling and structural deterioration in BC parkades, balconies and plaza decks. A condition survey maps delaminated and deteriorating areas non-destructively so repairs are scoped accurately and capital is planned, not guessed.
Delamination vs. sub-slab voids
Delamination is deterioration within the concrete element — cover separating from rebar, typically corrosion-driven. It is distinct from washout voids beneath a slab. This survey assesses the condition of the concrete itself across decks and structures.
What a condition survey maps
We map the extent and severity of deterioration:
Delaminated zones
Areas where cover has separated from the reinforcement.
Corrosion-prone reinforcement
Cover depth and zones at risk of ongoing corrosion.
Repair quantities
Mapped areas that quantify remediation scope for budgeting.
Non-destructive methods for decks & structures
We combine GPR (cover depth, rebar, moisture indicators) with chain-drag/sounding for delamination extent, producing a condition map for the engineer without coring the whole deck.
Detection methods we use
GPR survey
Maps rebar, cover depth and moisture indicators across the deck.
Sounding / chain drag
Delineates delaminated areas by acoustic response.
Condition mapping
Deterioration plotted to scale with repair quantities.

Frequently asked questions
How is delamination different from a void?
Delamination is separation within the concrete (cover from rebar, usually corrosion-driven); a void is empty space, often washout beneath a slab. This survey assesses the condition of the concrete element itself.
Is the survey non-destructive?
Yes. GPR and sounding map deterioration without coring the deck; any verification cores are minimal and at your engineer's direction.
Can you quantify repair areas for budgeting?
Yes. We map deteriorated areas to scale so repair quantities can be estimated for capital planning and tendering.
Does this support strata capital planning?
Yes. The condition map feeds depreciation reports and capital plans for parkade and deck remediation.
