AnchorMat

AnchorMat

(OP)
I think I posted in the wrong section previously.  Reposting in this section.

Anyone use the AnchorMat system consisting of Platipus anchors and Pyramat matting?  I am considering on a project to provide surface stabilization of a slope with gradients ranging from 1.5H:1V to near vertical.  Slope is composed of medium stiff to stiff clayey silt (n-values ranging from 12 to 30).  Slope is globally stable, but has been subjected to surficial sloughing and erosion for years.

If you have used it before, what did you think?  Any potential problems I need to consider?  What is the advantage of using the system over a typical erosion mat secured by driven rods?

Thank you in advance for your time.

RE: AnchorMat

Hi Check Maccaferri's Macmat-R system I find it better than Pyramat for type of application you are looking at. It has got a steel netting in the system which you can anchor down easily. Visit web site www.maccaferri-usa.com and go to product section.

RE: AnchorMat

I was involved in a project using the platipus anchors as part of a surface stabiliztion. There was some discrepency as to the strength of the cable. We were running load test and had the cables snap.  If I recall you can have different cables attached to the heads. I am not quite sure if the wrong material was sent to the job or if the manufacture indicated the wrong design strength.  The other issue which came up was locking them off; we were looking for a snug lock off using a cone and split wedges. We found (at least under our loads) the cable did not strech enough to get a snug fit. Ultimatly manta-ray anchors with treaded rods were used.

RE: AnchorMat

Edgeotech,

The anchormat system uses mostly stainless steel tendons because of the long design life and ease of installation.  If a tendon breaks it is because the anchor held more than the tendon.  The engineer should base his design around a combination of the anchor and tendon.

Most problems with the wedges are installer issues.  An educated installer with the right tools usually has no problem with them.  

Pyramat is typically used because it has great strenght and is much more flexible which allows it to conform easily to the slope.
