Introduction
Utilizing the siphon principle, the dimple board waterproofing system automatically and efficiently collects and channels water seepage in the soil into the rainwater collection well, enabling rainwater recycling for landscape. ( HW-PED14 composite membrane features an additional composite layer of root barrier membrane compared to the PED14.)
The system integrated waterproofing and drainage system is an innovative solution for planting roof. It efficiently channels excess seepage water from the soil, effectively controls the water table to prevent plant root rot, and replaces the traditional protective concrete layer and slope-forming layer. This system offers comprehensive advantages including cost savings, shortened construction time, reduced roof deck load, and extended building service life.
The system facilitates organized drainage by dividing large-area garage roof into multiple zones for zoned drainage, allowing rapid discharge of permeating water.

Features/Equipment characteristics
Integrated Automatic Drainage & Rainwater Harvesting: Effortlessly combines high-performance water discharge with sustainable resource recovery.
Efficient Siphon Driven Drainage: Delivers fast and reliable water removal through optimized siphon action.
Resource&Conserving Irrigation: Reuses harvested rainwater for landscape watering, supporting eco-efficient water management.
Construction Procedure
01.
Substrate Cleaning: The surface of the waterproofing layer must be thoroughly cleaned, with all dust, debris, and standing water removed.


02.
Based on the slope direction of the planting roof or the location of the outlet, determine the overall drainage direction. Mark and snap lines as per the drawings for positioning. After the positioning lines are set, apply butyl adhesive strips to fix and confirm the location of the siphon drainage channels.
03.
Lay the dimple board waterproofing composite membrane and geotextile parallel to the established drainage direction, reserve space for the siphon drainage channels, and ensure the overlap width meets design or code requirements.


04.
Remove the release film from the butyl adhesive strip and snap the siphon drainage channel into place. The channel should be bonded flush with the surface of the laid drainage board.
05.
The long and short edges of the drainage board are joined and secured using butyl adhesive strips with flush bonding. Overlaps between the drainage board and the geotextile are bonded with special adhesive.


06.
The edges of geotextile are sealed by adhesive bonding with an overlap width of ≥100 mm.
07.
Install the vented inspection pipe at the location specified in the drawings, and perform root zone protection as required by the design.
(Installation sequence: Tee drainage channel → vented inspection pipe → Dust-proof cap.)


08.
Lay geotextile over the siphon drainage channels. The geotextile overlaps must be bonded using specialized adhesive. (The roll width of the geotextile laid over the channels is 600 mm).
09.
The siphon device is installed at the outlet locations as designed in the construction drawings.


10.
Install the inspection well according to the construction drawings, and connect it to the siphon device at the roof outlet. The inspection well is connected to the stormwater inspection well via an overflow pipe. Installation of the siphon device and overflow pipe should be synchronized with the excavation and construction of the on-site rainwater and sewage pipeline network.
11.
The flow monitoring device, as detailed in the drawings, should be installed concurrently with the sedimentation inspection well, with the necessary conduit pre-embedding completed. It is advisable to install the power supply and data acquisition and processing unit after the exterior finishes are completed.


12.
Backfilling should be carried out promptly to prevent damage to the completed protective drainage layer by other trades. Construction machinery must not come into direct contact with the protective drainage layer.
Note: Mechanical equipment may only operate where the soil cover thickness exceeds 600mm. Areas serving as access routes for machinery require a soil cover thickness exceeding 800mm.
