Construction Erosion Control – Rough vs Smooth Slope

admin — Fri, 03 Feb 2012 13:00:20 +0000

Dramatic example of the effect of rainfall on a smooth versus rough slope. The rough side was “track walked” using a small Caterpiller tractor, the other side was “back-bladed” smooth with the same tractor. Both test plots were prepared with the same soil and then sprayed with bonded fiber matrix (BFM) with seed and fertilizer.

This is not the best way to get grass growing. The seed sits on the blanket which is a quarter to half inch above the soil. Since the seed needs to be in contact with the soil to have the best chance of growing, this will reduce the quantity of grass that grows. In a ditch, the more grass the better.

Last week’s video showed how a creative contractor constructed a slope tracking excavator bucket. This video shows the effect of a little rain on the slope. This is why the contractor didn’t want to use a heavy piece of equipment to track the slope as they knew that the slope would unravel from being too . . . → Read More: Rain on Roughened Slope Causes Slump of Eroded Mud into Ditch

Creative Contractor Makes Slope Tracking Excavator Bucket

Leave it to the contractor to come up with creative solutions. Confronted with a small, steep slope and wet soil, the contractor didn’t want to risk walking a small caterpiller up and down to roughen it before hydroseeding. Using some angle iron and an excavator bucket, they welded up a slope tracker. The operator tamps . . . → Read More: Creative Contractor Makes Slope Tracking Excavator Bucket
