Bio-Barrier Installation

[Mr. Sir]

I finally had a chance to use my "new" root pruner today. I installed the Bio Barrier along this driveway and walkway to deter the live oak roots from growing under the concrete.
I wanted to get some "action" shots, but I was working alone today. Fairly easy job; it took less than 3 hours to do 40 linear feet. The next one should go even faster now that I know what I'm doing.

 

[MasterBlaster]

I've done that, bleagh. Good money, though.

Are there holes in that barrier material?

 

[Mr. Sir]

It's a mesh material, similar to the landscape fabric that is supposed to prevent weeds from growing in your veggie garden.

It is porous, but has a slow release herbicide bonded to it.

Looks almost like GeoGrid.

hey is that a dosco, or a vermeer tool in the trailer?
Seen one of our crews do it in LA on ficus trees , dosco machine.
I ve thought on of those would be handy, but have been thinking an alpine machine would almost do the same job and grind stumps,
dont know if thats the desired cut on the root though.

How clean is the cut on the roots and how is the healing?

 

[sotc]

how do you bill that? linear foot? how deep does it go?

 

[Mr. Sir]

It's a Dosko. I picked it up at the machinery auction for a great price. Maximum depth is 15" and it 's about a 3" wide trench. It makes a fairly clean cut as long as the teeth are sharp.

 

[Mr. Sir]

I charge a base rate equal to my two hour minimum, plus a per linear foot charge.

I did some of that several yrs ago. I just used my stump grinder. It didnt go as deep as I needed so I did have to dig out the rest....

Ive also used a trencher to do some. as long as your quite a ways away w/ the trencher, it doesnt tear stuff up too bad.

Expect a lot of crown die-back on that tree, you'd have been far better off using an Air-Spade and making clean cuts with a silky root saw and loppers, just my opinion..

Why not just use a root deflector, imo putting more chemicals into the rhizoshere, can't be good long term

I'll monitor it and let you know how it fares.

Florida live oak roots quickly grow under, around, and over root deflectors.

Gotcha, how long will the herbicide last?

 

[Mr. Sir]

15 years, according to the label.
