6. 验收标准

防水层应进行闭水试验或其他检测方法，以验证其防水性能。

闭水试验应持续一定时间，水位应达到设计要求。

防水层应无渗漏、起泡、开裂等缺陷。

7. 其他要求

防水工程应由具有相应资质的施工单位承建。

防水工程应严格按照设计图纸和施工规范进行施工。

防水工程完工后应进行定期检查和维护，以确保其长期防水性能。

Exterior Waterproofing Standards

1. Materials

Waterproofing membrane: Must meet ASTM D412 or equivalent standards for tensile strength, elongation, and puncture resistance.

Sealants: Must meet ASTM C920 or equivalent standards for adhesion, flexibility, and water resistance.

Flashing: Must be made of corrosionresistant materials such as galvanized steel, aluminum, or copper.

2. Installation

Waterproofing membrane: Must be installed according to the manufacturer's specifications, including proper overlap and sealing of joints.

Sealants: Must be applied in a continuous bead and smoothed to ensure a watertight seal.

Flashing: Must be installed to prevent water penetration at critical areas such as rooftowall intersections, windows, and doors.

3. Testing

Water test: The completed waterproofing system must be tested by flooding the area with water for a specified period of time to ensure no leaks occur.

Adhesion test: The adhesion of the waterproofing membrane and sealants to the substrate must be tested to ensure they will not peel or delaminate.

4. Maintenance

Regular inspections: The waterproofing system should be inspected annually for any signs of damage or deterioration.

Repairs: Any damage to the waterproofing system must be repaired promptly to prevent water penetration.

5. Specific Standards

International Code Council (ICC): ICC 442.1, ICC 700.1, ICC 780.1

四、室外做防水需要什么步骤

室外防水步骤

1. 表面准备

清除表面上的灰尘、污垢和松散材料。

修复任何裂缝或孔洞。

确保表面干燥且无油脂。

涂抹一层防水底涂，以增强防水材料与表面的粘合力。

按照制造商的说明进行涂抹。

3. 防水涂料

选择适合室外使用的防水涂料。

按照制造商的说明涂抹防水涂料。

涂抹多层，每层之间留出足够的干燥时间。

4. 加固层

在防水涂料上铺设一层加固层，例如玻璃纤维网格布或聚酯毡。

将加固层嵌入防水涂料中。

5. 第二层防水涂料

在加固层上涂抹第二层防水涂料。

确保覆盖所有区域，包括接缝和边缘。

6. 保护层

涂抹一层保护层，例如丙烯酸涂料或聚氨酯涂料。

保护层可以防止防水涂料免受紫外线和机械损坏。
