T/SZWA 005-2021 Management Regulations for the Application of Concrete In-Situ Self-Healing Waterproof Materials

Scope

Scope: 1. Waterproof concrete with self-healing waterproofing materials, mainly used in concrete projects with waterproofing requirements, including: underground engineering, tunnels, culverts, pipe galleries, bridges, dams, pools, roof structures, etc. 2. When the basement floor adopts anti-floating anchors with dense anchors, and perforations in the external waterproofing layer are prone to leakage points after installation, making it difficult to ensure the construction quality of the waterproofing layer; and when the basement sidewalls adopt underground continuous walls, or the distance between the supporting piles and the basement sidewalls is small, leaving no safe operating space for external waterproofing, self-healing waterproofing concrete should be used. 3. To ensure the effectiveness of the application of self-healing waterproofing materials and the durability of the structure, the minimum cement content of the concrete should comply with the requirements of relevant norms and standards. 4. Self-healing waterproofing materials should be verified through trial mixing before use, and the performance of the waterproofing concrete should meet the design and construction requirements.
