Construction guidance:
1
Clean up the garbage on the paving site and level it with cement
There is no obvious concave convex on the site
2-5&permil is required for the outdoor garage roof and roof garden; Slope making;
2
Pave the cup-shaped mouth of the drainage board upward and buckle the perforations;
3
The drainage board is covered with geotextile, and the geotextiles are overlapped by 10~20cm to prevent muddy water from passing through the geotextile and silting up the storage and drainage system, resulting in poor drainage and reduced water storage;
4
Lay 10~20mm medium coarse sand on the geotextile to form a permeable filter layer, which can prevent the loss of planting soil;
5
Cover with planting soil of appropriate thickness

6
The finished drainage board shall be well protected
After the drainage board is paved, it is not allowed to directly push and transport trolleys on the drainage board
During the transportation of materials, wooden boards and packways shall be paved to ensure that the soil is filled as soon as the pavement is completed
