Features

Adding the ability to capture driftwood to existing dams

Installing the steel slit on the upstream side of those impermeable sabo dams often found across Japan, improves the functions of existing dams through added ability to capture driftwood.

Excellent driftwood capture

Reliably captures driftwood with its permeable structure of steel pipes. The excellent capture performance has been proven in actual results.

Excellent installability

Because the steel slit is installed on the upstream side of the existing impermeable dam with a retrofitting anchor, hardly any modification is required on the existing dam.

Conforms to the Design Guide for Overhanging Driftwood Capturing Works

The steel slit is designed in accordance with the "Guidance for Designing Overhanging Driftwood Capturing Work" published by the Sabo & Landslide Technical Center, addressing driftwood disasters which are becoming increasingly severe.
