Laying Direction of Waterproof Machinery Coil

Laying direction of waterproofing machinery rolls:
The overlap joints should be overlapped along the flow direction, usually parallel to the roof ridge or the long side of the roof.

On the premise of not affecting the waterproof quality, the principle is to minimize the length of the welding stitching gauge on the same roof. Precise lofting should be carried out before construction to minimize short lap joints. In some joints, adjacent joints are staggered at least 500 mm.
