Nichols Interchange flyover is a major traffic intersection in southern Metro Manila, Philippines, situated near Villamor Air Base at the boundary between Pasay and Taguig cities.

Renowned for its chronic congestion, the Sales Interchange often experiences gridlock, with vehicles taking up to 1.5 hours to traverse short distances during peak hours, impacting daily commuters and airport-bound traffic. This is why the re-waterproofing of the flyover deck was very hard to implement, as the heavy traffic would be further exacerbated, making the life of the commuters very hard.

CWS100 offers concrete waterproofing and protection for critical infrastruture and bridges, by disallowing water ingress, carrying soluble chlorides and contaminants that will undoubtedly degrade the concrete and initiate corrosion of the steel reinforcement of the bridge structure. Apart from that, CWS100 protects the deck against abrasion, and its high thermal-stress tolerance, allows for the asphalt layer to be placed on top of the treated deck, without the need for a protective screed, further accelerating the completion of the project and the final delivery for use of the community.

As a result of the use of CWS100, the service life of the bridge is greatly extended, while the future maintenance cost – paid from taxpayers’ money – is greatly reduced. Most of all however, it is the safety of human life that is the most important achievement, that comes from the life-long protection that CWS100 offers.
