For those concerned about whether it will become worn out after construction! Even after 5 years, the performance remains the same and blends well with the surrounding landscape.
For those struggling with the quantity of vegetation soil bags! Rontai will handle quantity and stability calculations for you.
The amount of water absorption and speed are the key factors! This is a security product for flood prevention that does not require a large storage space.
The workers' tasks have been simplified to just soaking the soil bags in water, contributing to labor and manpower reduction! By soaking in water, it is now possible to produce 20 kg of sandbags in 2 minutes!

Local excavated soil can be used at 2 tons per bag! We solve the problems of landslides. We have numerous construction achievements across the country, from road disaster recovery to agricultural roads and maintenance repairs.
Lightweight (approximately 9kg) and made of only two materials: sheet and ring anchor! A highly versatile civil engineering sheet that excels in workability and can be used for channel construction and drainage basins, hardening with water.
Finally usable in the field where we have struggled with muddy water for many years! The removal of white soil bags has been omitted, making it easy to complete the measures! The landscape of the green park has also improved!
