The lightweight permeable concrete core is made from crushed limestone aggregate, which provides high porosity while maintaining structural stability, allowing water to pass through at a consistent rate without clogging. The matte natural concrete finish matches most outdoor hardscaping materials such as pavers, stone, and wooden decks, eliminating the need for additional landscaping cover. The interlocking tongue-and-groove design ensures a tight, stable fit between segments, preventing shifting during installation or over time due to soil movement. Unlike plastic or HDPE blind drains, this concrete product does not require additional geotextile wrapping, reducing installation time and material costs. It is also LEED v4.1 compliant, making it suitable for sustainable residential and commercial landscape projects seeking green building certifications.
Each segment is 10 linear meters long, with a width of 200mm and a height of 100mm. The porous concrete has a porosity rate of 35%, with a drainage flow rate of 150 liters per hour per linear meter. The compressive strength is 300 kPa, allowing it to support up to 30 metric tons of vertical load per square meter, making it suitable for light foot traffic and occasional lawn mower access. The operating temperature range spans from -10°C to 70°C, and the concrete is resistant to UV fading and moisture damage. Installation requires a 25cm-deep trench with a 5cm layer of sand beneath the segment to ensure stable placement and proper drainage.
Primary applications include residential patio and walkway drainage, garden bed and sloped landscape erosion control, commercial park and outdoor dining area drainage, and rooftop garden subsurface drainage. It is also suitable for use around swimming pool decks and outdoor fire pit areas to manage standing water. The product is ideal for landscape designers, residential contractors, and commercial property management teams looking to combine functional drainage with cohesive outdoor design, creating a tidy, visually appealing outdoor space while solving water-related landscape issues.
