,Recycled PP Stormwater Geocellular Module
The Vantra WQ-M1001 is a professional-grade recycled PP storm water soakaway crate designed as a complete eco-friendly rainwater harvesting and reusing system for underground installation. Combining structural strength with environmental responsibility, this modular crate captures, stores and reuses stormwater while helping your project meet modern sustainable drainage standards.

The WQ-M1001 features a reinforced rib and pillar structure delivering high compressive strength, so it can be safely buried under lawns, green belts, permeable pavements, driveways and parking areas. Made of corrosion-resistant recycled polypropylene, it withstands soil acid, alkali erosion and root penetration for decades of reliable underground service.

Precision interlocking snap joints allow fast horizontal and vertical assembly without glue or heavy machinery. Engineers can configure custom-sized underground storage chambers to match specific capacity and site requirements, cutting construction time and labor costs compared with concrete alternatives.
The high void ratio open frame maximizes effective storage volume and keeps water flowing freely. Wrapped with geotextile, the system filters sediment and prevents clogging, supporting long-term infiltration, storage or controlled discharge. It buffers peak runoff, relieves drainage pressure and aligns with LID and sponge city standards.
Harvested rainwater can be repurposed for landscape irrigation and non-potable uses, cutting mains water consumption and lowering operational costs — a practical water-saving measure for green buildings and eco-development projects.
Ideal for landscape contractors, civil engineers and sustainable developers, the Vantra WQ-M1001 delivers a durable, low-maintenance, cost-effective underground stormwater management solution for residential, commercial and municipal projects.
