Before construction, the base layer that has passed the acceptance inspection should be cleaned up and the dust on the edges should be blown off.
The treatment of the base layer should be uniform and consistent, and repeated brushing should be avoided.
After the base treatment agent is dried, the roof waterproofing project and the underground waterproofing project that require additional layers should be laid with additional layers according to the design requirements.
Determine the sequence and direction of laying the roll material and mark the line on the base layer. If the roll material occupies space during laying, the pasting of different parts of the roll material should be carried out according to the requirements.
Roof: bonding of rolls and base points or strips; The 800mm surrounding area of the roof should be fully pasted; The bonding area of the sloping roof is over 70%, and 100% of the bonding between the rolls is complete;
Basement floor: The roll material can be fully bonded, point bonded, strip bonded, or laid empty to the base layer, but the roll material must be fully bonded between rolls;
Basement vertical wall: The rolls should be fully adhered to the base layer and between rolls;
Additional layer: Generally, all parts are fully pasted, and empty paving is allowed at deformation joints.
