Overpass Waterproof
2017 Chengdu city viaduct waterproof renovation adopted polyaspartic coating, anti-humidity & traffic vibration for basin municipal infrastructure.
Product & Project Basic Info
Our polyaspartic waterproof coating is specially customized for municipal traffic infrastructure. This real engineering case was delivered in Chengdu, China in 2017, focusing on comprehensive waterproof protection for city overpass viaducts.
Why Polyaspartic Coating Fits Chengdu Overpass Projects
Chengdu basin features heavy annual humidity, constant mist and mild temperature fluctuations. Urban overpasses sustain long-term vehicle vibration and rainwater erosion. Conventional waterproof materials cannot balance elasticity and weather resistance, which easily causes cracking and bridge leakage.Our polyaspartic waterproof coating solves these two core pain points at once:
- 1: High elastic stretch covers vibration-induced micro concrete cracks
- 2: Dense waterproof film resists long-term damp fog and rain infiltration
- 3: Good adhesion on bridge concrete base, no peeling or blistering
- 4: Eco-friendly formula without harmful substances, fit municipal public works
On-site Application Result
After full coating construction in 2017, the Chengdu overpass has maintained zero-leakage status for years under local humid foggy weather. The municipal bureau no longer needs frequent bridge maintenance, greatly cutting traffic operation costs.This coating is widely applicable for urban viaducts, highway overpasses and all municipal traffic infrastructure waterproof renovation.
