Ultratect WR was applied to a 50-story high-rise condominium located along the coast to address salt damage, waterproofing, stain resistance, and carbonation suppression.
The treatment contributes to improving the building’s durability and reducing long-term maintenance costs.

Challenges and Countermeasures for Coastal High-Rise Condominiums

High-rise condominiums near the ocean are exposed to harsh environmental conditions, including salt-laden sea breezes and airborne debris driven by strong winds.
These factors can accelerate structural deterioration and present challenges such as:

• Salt damage to concrete (rebar corrosion and structural degradation)
• Waterproofing failure at joints (leading to water intrusion)
• Carbonation of concrete (resulting in reduced durability)
• Staining and mold growth on exterior walls
• Rainwater infiltration due to reduced waterproofing performance

To address these issues, Ultratect WR was applied as a long-term protective measure.

Why Ultratect WR Was Chosen

To maintain the building’s architectural appearance and structural durability while minimizing maintenance costs, Ultratect WR was selected for the following reasons.

High Salt Resistance Performance

• Silane?siloxane components penetrate deep into the concrete and block chloride ion infiltration.
• Helps suppress rebar corrosion and extends the service life of the structure.

Waterproofing at Joints and Carbonation Suppression

• Maintains concrete breathability after application while preventing water intrusion.
• Improves waterproofing performance in tile joints and protects against deterioration caused by water ingress.
• Suppresses carbonation, enhancing the durability of the concrete.

Stain and Mold Resistance

• Low dirt adhesion allows rain to wash away grime, helping maintain long-term appearance.
• Inhibits mold and algae growth, lowering the frequency of exterior wall maintenance.

Improved Waterproofing Performance

• Prevents rainwater penetration and protects joints and exterior walls from degradation.
• Provides waterproofing without a film, preserving the exterior’s aesthetic finish.

Given these advantages, Ultratect WR was selected to help preserve the long-term asset value of the high-rise condominium.

Ultratect WR offers a reliable, long-term solution for enhancing durability and reducing maintenance costs in coastal high-rise condominiums and other structures exposed to salt damage.
