Moyai Drainage Method - Rainwater Storage Infiltration Layer

Can be used in rainwater retention and infiltration facilities! Equipped with runoff control functions to protect the retention tank body.

The "Moyai Drain Method 'Rainwater Retention Infiltration Layer'" is used as an alternative material for filling aggregates such as single-sized crushed stone in rainwater retention infiltration facilities, as well as a cushioning material to protect the main retention tank. By using factory-produced products with high dimensional accuracy, the flatness of the foundation ground is ensured, allowing for stable construction as a measure against unevenness. A rainwater retention structure integrated with the main retention tank can be formed. With a void ratio of over 80%, the outflow suppression function is improved compared to aggregates like single-sized crushed stone. The unique structure of the Moyai Drain has been evaluated by the review committee of the Rainwater Retention Infiltration Technology Association (public corporation) as being applicable for rainwater outflow suppression facilities. [Moyai Drain Method] - Simplifies the construction process, leading to a reduction in construction time. - Can be installed around the outer perimeter of the main body and used as a cushioning material with outflow suppression functionality. - Eco-mark product using 50-60% recycled materials. *For more details, please refer to the catalog or feel free to contact us.
