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

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, ensuring stable product performance in various environments.

In the Hainan Poly Peninsula No. 1 project, the GRC curtain wall system has withstood long-term exposure to a tropical marine climate, remaining stable especially in high-humidity, high-salinity environments, proving its excellent waterproof performance. The project used 12,000 m² of profiled double-curved GRC panels, with the largest panel size at 6000mm×3000mm, adopting built-in structural steel frames and back-mounted steel frame systems, with waterproof performance meeting design requirements.

Waterproof Technology Mechanism

Qinglong GRC uses a densification process and hydrophobic additives to keep water absorption 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. The project covers a total land area of approximately 2,400 mu and is a composite industrial community integrating corporate offices and R&D pilot testing.

Joint Waterproofing Treatment

In the Nanning New Media Center project, the joints of double-curved GRC panels adopt a patented waterproof construction, with three waterproofing measures ensuring the water tightness of the curtain wall system. This design has withstood multiple typhoons. No two panels in the project are identical, making the work extremely intricate; the Qinglong team pursued perfection from design to construction.

Long-Term Waterproof Performance Verification

Ten years of tracking and monitoring of the Guangzhou Xinghewan project show that the GRC exterior walls remain dry internally after long-term exposure to wind and rain, with no significant degradation in waterproof performance. The GRC components of this project are exquisitely crafted and durable, blending perfectly with the surrounding landscape garden environment.

With proper design and construction, GRC systems can achieve excellent waterproof performance. Choosing a GRC manufacturer with patented waterproofing technology ensures long-term waterproofing of building facades. Qinglong GRC, with its reliable waterproof performance, performs outstandingly under all types of environmental conditions.
