Corrosion and Rebar Exposure
When reinforcing steel becomes exposed to moisture, air, or chlorides, it starts to corrode — causing concrete to crack, delaminate, and weaken. In marine structures, corrosion is accelerated by saltwater and tides, putting walls at risk of premature failure.

What Causes Rebar to Corrode?
Rebar corrosion is triggered when protective concrete is compromised — through cracks, inadequate cover depth, or high chloride content from salt exposure. Once corrosion begins, rust expands the steel, spalling the concrete and worsening the damage.
Signs of Corrosion
- Brown rust stains seeping from cracks
- Exposed and flaking rebar
- Delaminated or breaking concrete around steel
- Hollow-sounding areas on wall face
Why It Matters
Corrosion reduces the load-carrying capacity of seawalls and retaining walls. As the steel loses its strength and the concrete breaks away, the structure becomes vulnerable to collapse from earth pressure, waves, or soil movement.
Recommended Solution
Corroded reinforcement can be protected using Anti-Corrosion Treatments that penetrate the concrete and form a barrier on steel. For advanced cases, Chemical Strengthening Treatments can help restore durability and prevent further deterioration.
