Roof Cell

Roof cell is also called rrainage cell which reinforces the efficient sub-surface drainage as well as the ventilation of the contractors’ landscapes and building foundations. It is common to make these cells with high-strength polypropylene or polystyrene, which have three-dimensional structures resembling honeycombs; that allows for fast water absorption and movement. In a bid to achieve this configuration, they are designed in such a way that even at higher compressive loads; it remains water flow friendly.

Introduction:

Drainage cell is also called roof cell,a lightweight, high-strength modular component used to provide efficient drainage solutions. It is commonly made of high-density polyethylene and is used to provide a void zone through which water can travel, preventing water logging and encouraging effective drainage. Drainage cells are an important component in modern landscaping and building projects, providing a dependable means to manage water and maintain the integrity of diverse structures.

Key Product Characteristics

Dual Drainage & Water Storage Function Quickly evacuates surplus stormwater while reserving water inside cells. Stored water can wick back upward to supply soil moisture for vegetation, reducing irrigation demand.
High Compressive Strength & Light Weight Low dead load on roof slabs while bearing pedestrian and light vehicular loads. Avoids heavy gravel drainage layers to reduce structural burden on rooftops.
Waterproof Membrane Protection Shields roof waterproofing layers against punctures, UV ageing and thermal shock, greatly extending the service life of waterproof membranes.
Modular Interlocking Design Simple click-fit assembly, fast laying on flat roof surfaces, easy cutting to fit irregular layouts.
Eco-friendly & Stormwater Management Cuts stormwater runoff volume, helps urban rainwater recharge. Green roof assembly reduces building heat island effect, lowers indoor cooling consumption and improves air quality.

Main Applications

Green Roof / Rooftop Garden: Extensive and intensive green roofs for commercial buildings, residential flats and public facilities.
Landscaped Decks & Planter Zones: Raised planting beds, podium landscape and terrace planting areas.
Retaining Wall & Planter Drainage: Drainage layer behind retaining walls and vertical garden systems.
Sports Fields & Landscape Projects: Substrate drainage for lawns and recreational landscape areas.

Installation Process Overview

Base Inspection: Check roof waterproofing layer and confirm no leakage.
Lay Roofcell Modules: Interlock panels tightly to form continuous drainage layer over waterproofing.
Geotextile Coverage: Spread filter geotextile on top of Roofcell to prevent soil particles clogging hollow cells.
Substrate & Vegetation: Fill growing medium and plant green vegetation.

FAQ

Q: What happens if the product is damaged during transportation?

A: We take the following measures to reduce risk: Export-grade packaging + pallet securing; Taking photos to confirm packaging condition before shipment; Arranging third-party pre-shipment inspection (SGS, etc.).

Q: What trade terms and payment methods do you accept?

A: Trade Terms: FOB (major ports such as Qingdao/Shanghai/Tianjin), CIF, and CFR are all acceptable. Payment Method: T/T wire transfer (usually 30% deposit + 70% balance upon receipt of copy of bill of lading), details negotiable.

Q: Can you provide samples?

A: Yes. We provide free samples (small size), with shipping costs borne by the buyer. For pre-production samples before large-volume orders, a sample fee is required, which will be refunded upon placing a formal order. Samples usually come with corresponding test reports for customer verification.

Q: What are the production cycle and delivery time?

A: Standard products are typically produced and shipped within 10-20 business days after order confirmation. This depends on: product type and quantity; whether customized specifications are required; and we recommend informing us of your target delivery date in advance so that we can arrange production and booking accordingly.

Q: How should the product be packaged? Is it suitable for sea freight?

A: All products use export-grade packaging: Geotextile/Geomembrane: Roll packaging, with an outer PE film or woven fabric protective layer, suitable for container loading. Geocells: Can be folded into rolls to save on shipping costs. Drainage Boards: Flat or roll packaging, depending on order quantity. Packaging design fully considers the requirements for moisture and abrasion protection during sea transport. Palletized packaging and customized shipping marks are available.

Q: What is the minimum order quantity (MOQ)?

A: The MOQ varies depending on the product: Geotextile/Geomembrane: There is no strict MOQ for standard specifications, but ordering in rolls is recommended to optimize costs. Geocell: Usually priced per area, small batch orders are acceptable.
