Wet-application Construction Technology-Operation Condition

1. Quality acceptance to last step project before construction.

2. All pipe fitting should be pre-covered and seal treated.

3. The substrate should be clean and smooth.

4. The internal and external corners of substrate wipe to circular. The min radius of internal corners is 50 mm and the max radius of external is 20 mm.

5. There is no pounding on the substrate when construction.

1. Before waterproofing project construction, should be quality acceptance to last step project, and then can be construction.

2. All pipe fitting should be pre-covered as designed and standard requirements, and to be seal treated.

3. The substrate should be clean and smooth, no obvious protruding parts.

4. The internal and external corners of substrate wipe to circular. The min radius of internal corners is 50mm and the max radius of external is 20mm.

5. There is no ponding on the substrate when construction, if it has ponding, should be clean up before construction.

1. Maintain substrate concrete to the defined period, according with design and specification requirements.

2. Clean up dust and sundries on the substrate paved and adhere to waterproof membranes.

3. Keep the internal and external corner circle arc and the surface dry, make sure the moisture content less than 9% (dry test: pave 1㎡ membrane smoothly on the screed-coat, then check the membrane paved side whether has watermark or not after 3~4 hours, if not, it can construct )

1. Substrate is firm and the evenness matches up the design and specification requirements.

2. Keep surface dry, clean, no dust and greasy dirt.
