The product was sheet-like (33cm × 33cm). The design choice of models is a hard plastic, high strength load bearing capacity building green landscape linked structure, the plate material. Consistent, double-sided modular design of the drainage water storage separated from the root plate to meet the design and use of green roof specification requirements 

 Design, construction points: 

 For the park under construction, flower beds, planters and flower beds, directly to the drainage water storage moisturizing layer separated from the root plate and filter instead of the conventional materials (such as ceramic, pebbles or shells composed of the filter layer. 

 2, for the old and new roof or underground engineering roof and other hard interface Green, before laying is water separated from the root plate, the first clean up the site debris, set up a waterproof layer in accordance with the requirements of design drawings, and then the cement mortar to find the slope, so that surface without obvious bump at the water according to the slope and the flow of the orderly emissions, laying within the scope without additional provision of drainage blind ditch. 

 Used to do architectural sandwich panels, build drainage across the root board laying on the roof concrete panel, build and assemble a layer of single wall drainage and then separated from the root plate, or steel mesh powder cement, or in-situ concrete to protect underground water seepage through the drainage board, overhead space into a blind ditch to the sump. 

 4, the drainage water storage every root plate around each other splicing laying gap, as the lower drainage channel on geotextile filter also need to lap the moisture layer laying. 

 No gaps drainage impoundment separated from the root plate laying is completed, the next process, laying the filter cloth and stroma as soon as possible to prevent soil, cement, sand clogging pores or into the drainage water storage reservoir storage water separated from the root plate, drainage space to ensure that is water on every root plate to fully play its role. Filter geotextile above the upper berth in the operating board, a landscape, green construction.
