Preparing steep slopes for turf reinforcement mat, scraper / packer
(OP)
Can anyone advise based on past experience best method / equipment for scraping down and smoothing a badlands type crevice laden sandstone, steep slope (up to 5:1) to accept an Enkamat / hydromulch type erosion mitigation system? Face of slope is up to 30' in height with limited access from the top of slope. The bottom of the slope may be inaccessible for any heavy equipment due to rail operations. Appreciate the reply.
Thanks!
Thanks!

8" min. U shaped soil nails are inserted / triangulated through the mat at 3' o.c. to keep the mat adhered to the slope grade so plant material roots into the sandy surface. This system has successfully been used on slopes up to 70 deg.

These are common (used to be anyhow) for mining gravel under water in stream beds. A derrick or similar is mounted at one end of the site and a cable is run through a pulley there. The operations are then run from the other end via a crane rig that moves about to move the path of the dragline bucket across the area. Distances up to 100 yards have been used for these mines. The bucket drags from the derrick toward the crane.
If you look at the TV program of Lumbering (History channel) their method of hauling up logs is similar. A moveable end anchor could be arranged if one thinks about it (maybe a crawler-dozer with side mounted mast).
Instead of a dragged bucket, perhaps a blade mounted on wheels (as from a tractor) may be OK for grading.
My cogitating.

Interesting subject. If one goes this route, a suitable tool for he "bucket" would be a drag made of structural shapes, such as angles or H sections. These drags are frequently used for grading gravel roads, hauled along behind a truck or tractor. Sections are mounted to steer the gravel back and forth. Even a section of chain link fence with some weights on it works pretty good on loosened material.

You can only do this in Alaska, though.

This site has a video clip of one operation. They may advise details and equipment to think about.

The system used for US football game video from over the field is another idea for covering a large area, but not of sufficient power.
