Rebar Rust & Falling Concrete
Flaking stucco, exposed rusted rebar, and chunks detaching from lanais, overhead beams, or exterior walls.
Bowing, Leaning & CMU Cracks
Hydrostatic pressure, failing weep holes, and step cracking on CMU block hillside retaining walls.
Cracked Slabs & Sticking Doors
Volcanic soil movement, slab heaving, subterranean moisture seepage, and diagonal door header cracks.
Concrete spalling (known locally as 'concrete cancer') is the #1 threat to Hawaiian properties. Airborne salt molecules migrate into the concrete matrix, attacking the internal steel rebar. As the rebar rusts, it expands up to 6 times its original volume, blowing chunks of concrete right off the structure.
Falling concrete debris presents an immediate safety hazard and liability for homeowners and HOA boards. Delaying structural intervention allows moisture to travel deeper along the reinforcement grid, turning a $1,500 repair into a $25,000+ structural overhaul.
Hawaiian trade winds deposit concentrated airborne chlorides into porous concrete capillaries, breaking down the alkaline protective passivating layer around embedded steel.
As the steel oxidizes in high tropical humidity, rust creates up to 9,000 PSI of outward radial pressure, shattering the concrete from the inside out.
Our C-31 structural partners saw-cut damaged concrete, mechanically clean and zinc-passivate rebar, and rebuild with polymer-modified structural mortar.
If you notice any of these structural symptoms, an immediate photo assessment can prevent further degradation:
