Roof membrane waterproof construction process, what should be noted that?
Foundation treatment to find leveling to pay attention
Five to:
1 slope accurate, smooth drainage
2 surface is flat
3 strong
4 clean
5 dry
Coil ply attention
Paving direction, slope less than 3%, parallel and roof paving, slope greater than 15% or roof vibration, perpendicular to the roof paving. Slope between 3% to 15%, can be parallel to the vertical; membrane waterproof roof slope should not be greater than 25%. The upper and lower layers may not be piled on each other.
Three do
1 to do concrete or mortar ratio is accurate
2 to do the surface of the second calendering
3 to be fully maintained
Four do not:
1 surface can not afford sand
2 surface can not afford skin
3 surface is not crisp
4 does not crack
