Custom Counterfort Drain and Trench Stabilizer
Laying Nova-Flo, scoria and Geo-texile cloth is a time consuming and therefore costly operation. Bob designed and built a counterfort drain and trench stabilizer. This solved the problem of stabilizing the trench and making the job of laying the Nova-Flo, scoria and Geo-textile cloth safer and less time consuming.
