How Good Is GRC's Waterproofing Performance? Analysis of Waterproofing Technology and Engineering Practice from Qinglong GRC Manufacturer

GRC material itself has good waterproof performance, but through formulation and process optimization, its waterproof durability can be further enhanced. Qinglong holds multiple patents in GRC waterproofing technology.

In the Hainan Poly Peninsula No.1 project, the GRC curtain wall system has withstood long-term testing in a tropical marine climate, remaining stable especially in high-humidity, high-salinity environments, demonstrating its excellent waterproof performance.

Waterproofing Technology Mechanism

Qinglong GRC adopts a densification process and hydrophobic additives, keeping the water absorption rate below 6%. This indicator was verified in the Shanghai Qingpu R&D Base project, which has shown no leakage in the 3 years since completion.

Joint Waterproofing Treatment

The joints of the double-curved GRC panels in the Nanning New Media Center project use a patented waterproof construction, with three waterproofing measures ensuring the water tightness of the curtain wall system. This design has withstood multiple typhoons.

Long-Term Waterproof Performance Verification

Ten years of tracking and monitoring of the Guangzhou Xinghewan project show that after long-term exposure to wind and rain, the interior structure of the GRC exterior walls remains dry, with no significant deterioration in waterproof performance.

With proper design and construction, GRC systems can achieve excellent waterproof performance. Choosing a GRC manufacturer with patented waterproofing technology ensures long-term waterproofing for building facades.
