Siphon drainage channels play a crucial role in the garage roof siphon drainage system. Rainwater infiltrates into the soil on the garage roof, and the infiltrated water is collected and discharged in an organized manner. During this process, we employ grid-based treatment to transform large issues into manageable drainage areas, achieving from surface collection to on-site collection. At the discharge point, we utilize the siphon principle to form an organized (grid-based) active extraction of drainage.

Siphon Drainage Rainwater Collection System

I. Six Key Advantages of Hongji's Rainwater Harvesting and Drainage Collection System

Addressing the difficulty of slope finding for large-scale overhead plates, achieving organized drainage with zero slope.

【2】Eliminate the slope layer, protective layer, insulation layer, and replace the traditional drainage filtering layer.

Construction is convenient, saving 3/4 of the construction period and 1/3 to 1/2 in cost.

【4】Collect infiltrated water for garden irrigation, conserving water resources.

【5】Waterproof, breathable, and thermal-insulating features.

Easier to maintain, reducing clogging phenomena.

Two: Five Key Features of the Siphon Drainage Rainwater Collection System

【1】Organized drainage of excess infiltration water from soil layers, with high siphon drainage efficiency and rapid drainage speed, allowing for the elimination of the need for a slope layer.

【2】The combined construction of a waterproofing layer with a drainage system effectively alleviates the leakage issues of the garage rooftop.

Maintain lower water levels on the planting garage roof to enhance aeration at the bottom of the planting soil, preventing plant death due to waterlogging and ensuring normal plant growth.

The collected rainwater can be used for irrigation and cleaning, achieving the goal of secondary utilization of permeable water, thereby saving operational costs.

Reduce the load on the roof of the building and minimize the amount of earth excavation.

Section 3: Siphon Drainage Collection System Working Principle

Rain or irrigation water seeps through the soil layer to the garage roof composite protective drainage inserts.

【2】Water flows into the garage roof drain channels.

Through vertical siphon drainage pipes arranged around the garage perimeter, a gravity flow combined with siphon effect is generated, leading into the sedimentation observation well.

Rainwater is settled and then the clear water is injected into the reservoir.

Later, the property management will recycle the clean water from the reservoir for secondary use or discharge it into the rainwater network.

Four: Six Major Advantages of the Siphon Drainage Collection System

【1】Excellent drainage performance

The composite protective water sheets are formed by a single molding process of high-density polyethylene and resins through vacuum forming, thermal melting, and lamination, featuring excellent drainage and ventilation channels with superior drainage performance.

【2】 No slope layer required

The basement parking garage's ceiling is divided into sections, with drainage channels installed to organize and discharge infiltrated water systematically.

【3】Root-resistant piercing effect

High-density polyethylene is a raw material that does not contain plant-affinity substances. It boasts a very high density, and composite protective drainage sheets produced from this material can construct an excellent root-resistant layer.

【4】Flexible protective coating aids in waterproofing assistance

Composite protective drainage sheets offer excellent compressive and tensile strength. Their unique convex design provides effective cushioning, offering complete flexible protection to the waterproofing layer and preventing damage from backfill soil. Long-lasting composite drainage boards are sealed with double-sided self-adhesive waterproofing (Sticky Boss) flat joints, allowing infiltrated water to flow across the composite drainage board. The boards isolate infiltrated water from the waterproofing layer, serving as an auxiliary waterproofing solution.

Shorter project timeline, lower cost.

【6】Achieve the recycling of rainwater and irrigation water
