Plastic rainwater storage material "Cross Wave" *Sample model available.

Plastic rainwater storage material "Cross Wave" *Sample model available.

Manual stacking is OK! High void ratio with minimal excavation volume. A catalog with construction case studies is also available.

"Crosswave" is a plastic rainwater storage material that can be easily buried by hand beneath parking lots, parks, and school grounds. It allows for a high void ratio, which reduces excavation volume and shortens construction time. In addition to suppressing rainwater runoff, it can be utilized for purposes such as rainwater reuse (for domestic wastewater and industrial/agricultural water). *Currently, we are offering a "Product Catalog" that includes case studies! 【Features】 ■ No curing period required for concrete construction methods ■ Earthquake resistance level 2 ■ Supports vertical loads of 25t trucks ■ Made from environmentally friendly recycled polypropylene ■ Excellent chemical resistance and water resistance, preventing water contamination 【Additionally! We are giving away sample models of 'Crosswave'】 If you are interested, please apply through the "Contact Us" section. (Limited to 20 companies. If there are many applicants, a lottery will be held.)

Crosswave Construction Examples

Crosswave Construction Examples

High void ratio! Plastic storage material that efficiently collects rainwater. Numerous construction examples introduced!

We would like to introduce a case study of the plastic retention material "Crosswave," which prevents urban flooding with a high void ratio. The construction process is simple, as it only requires stacking the units in an alternating manner, making it widely used in various locations such as rainwater utilization systems, underground adjustment ponds, rainwater utilization facilities, and disaster prevention adjustment ponds. Additionally, by using "Plaroad" as temporary road material, it is possible to efficiently construct and dismantle temporary roads. 【Case Studies (Partial)】 ■ Adjustment pond for land readjustment in Ishikawa Prefecture (Storage capacity: 9,200m3) ■ Adjustment pond for the Miyagi Prefectural Office (Storage capacity: 1,700m3) ■ Adjustment pond for residential land development in Chiba Prefecture (Storage capacity: 420m3) ■ Adjustment pond for a shopping center in Aichi Prefecture (Storage capacity: 6,600m3) ■ Adjustment pond for an elementary school in Fukuoka Prefecture (Storage capacity: 800m3), etc. *For more details, please refer to the PDF document or feel free to contact us.

"Crosswave," a plastic retention material that prevents urban flooding with a high void ratio.

"Crosswave," a plastic retention material that prevents urban flooding with a high void ratio.

Plenty of rainwater stored underground. Lightweight, can be installed manually, and has a short construction period. Accessible for 25-ton trucks.

"Cross Wave" is a plastic storage material that ensures a high void ratio by stacking it underground while intersecting, allowing for efficient rainwater collection. It is extremely lightweight, eliminating the need for heavy machinery during installation or concrete curing. It features a high load-bearing design that can support the passage of 25-ton trucks. It allows for easy construction of water storage tanks beneath parks, schools, and commercial facilities, contributing to the mitigation of urban flooding and rainwater runoff. 【Features】 ■ High load-bearing design. The allowable stress in the vertical direction is 90 kN/m². ■ Excellent chemical resistance and water resistance, and does not contaminate water. ■ Capable of flood control measures for rainwater from river flooding and sudden heavy rains. *For more details, please refer to the catalog or feel free to contact us.
