Pond Boss Forums POND CONSTRUCTION Soil questions Liner companies in Eastern NC

No clay found on site so looking at options.

Thanks

Andy G. with GetsCo out of Middlesex, NC is very knowledgeable and helpful. If you would like his contact info, I can certainly get that over to you.

I am in contact with them now. Thanks!

I had to look into a liner for a pond that a contractor wanted to build. 1.25 acres. The EDPM liner that had to be seamed on site would have run almost $200K. I got a quote from Bend Tarp Liner BTL in Oregon. They could make 2 different thicknesses of liner that were one piece with no seaming, and an even heavier liner that needed 1 seam. The seamless liners were 1/4 the price of the EDPM liner.

No matter what liner you use, you need to cover it with soil. The BTL liner didn't need an underlayment, the ECPM liner needed an underlayment too.

Wow 200k is insane!
Got one quote back so far and it's a Waaaayyyyyy lower than that.

The quote from BTL was Waaayyyyyy lower than the $200K quote. You just need a bunch of people to lay it out, it's recommended that you have 1 person every 10-15 feet to unroll it.

Mike,

Not to rain on your parade, but based on your other threads, how are you going to keep your pond full even with the installation of a liner?

Are you going to use surface run-off water? Based on your description of the slope of your property, that may be possible? Are you going to pump some water from your creek?

P.S. I forgot to add one important comment in your other threads. Have you looked at the satellite image of the properties around you? If there are a fair number of ponds in the area, then it is likely you can build a pond with the soil materials available to you.

Do you know any of your neighbors with ponds? That is an excellent resource to determine if they have surface water ponds, groundwater ponds, used a liner, etc.

With the liner it would be mostly surface runoff.
In addition to that one contractor brought up the possibility of some drain lines from other areas to catch surface and groundwater to supplement.

There are a couple ponds around that I know of . I'll check the satellite image for more. Good idea

Right now I'm leaning towards renting an excavator. I need a bunch of trees taken down and the cost to pay someone is almost as much as a weeks rental. Day or two taking trees down then dig a big pit at the lowest point and see if it stays at an acceptable level year round.
Neighbor needs some work done too so that could help pay the rental also.

Thanks for your input.

Drain lines certainly work to bring more water. Another option is to build some berms.

Our farm in Kansas is pretty flat. My wife likes to do some landscaping where I have built some little hills. (She is much better than I am at making things "pretty".) A terrace or berm that enhances your view of the pond from the house AND brings more water might also be a good option.

P.S. When you excavate the pond site, you will have a lot of spoils. You will need to place them somewhere on the property. If they are mostly the crappy sand and clay mix that you got on your tests, you will probably need to strip your good topsoil in the location of your spoils, build your spoils piles, and then re-cover with your good topsoil. You could also use some of the spoils material for some interesting landscaping on your property!

I'm gonna berm around the sides and rear in case the creek rises it won't wash a bunch of stuff in my hole.
Abandoning a ditch line, repairing wash out etc. I got some plans for the spoil. A lot of it anyway.

Definitely stripping tip soil first. There is at least 2 foot of it down the bottom of property.

Test holes at top of slope are still holding water.
I love working the tractor so I'm sure there will be lots of changes over the years back there.
Having a stock pile of fill won't hurt a thing.
Just gotta get a spot to hold water.
