Have been looking at diff seawall options as currently have rip rap and tired of the snake dens, re-stacking annually, etc. Has anyone ever had an experience with such as any feedback would be appreciated.

Have considered the following and here are my thoughts on each:

Wood - Will not last over 15 or 20 years (my opinion)
Pured Block - To many failure points
GeoStone - Almost as expensive as poured concrete wall
Poured concrete - Expensive to say the least

Vinyl - Guaranteed for 50 years plus cost of materials including all tie backs, bolts, washers, wales, etc about $53.00 a linear foot for an average 7 foot tall wall plus installation (which appears rather simple, just time consuming) and does not require concrete footings, etc.

If anyone is interested here a a link to one of the companies website I am considering and their manufacturing plant is in Bham, so freight is cheap. Plus have engineers which will spec out your job based on the lakebed soil (clay, sand, etc) and the grade of lot to the seawall. For the engineers in the group you can check out their engineering plans by clicking on the Engineering link in the left nav bar.

How long a wall are you going to build?

Rather impressive looking Mav. It would seem like the vinyl product would be less abrasive to boats and other toys coming in in contact with it.

I kind of wish I had gone with the GeoStone on my seawall as opposed to wood. We did use it for our retaining wall. The Geo was more expensive than two other bids I received for poured concrete, but it looks much better. It was approximately 10% more in cost but came in colors and shapes not offeren in the lower priced poured concrete bids. Shape meaning the curves of the wall and the stying of the stone appearance. I will attempt to send you a couple of personal pictures of my wall.

The GeoStone is a lot of heavy lifiing. I think the individual pieces are 35 lbs and the top sections are about 60 lbs. I could be wrong on the weights. Two homeowners across the sleugh from my place are putting in the GeoStone Seawalls and doing it themself. I could not do it, but theirs looks great.

I wonder if there are any examples in the area of the vinyl product you could go and look at????

Vinyl seawalls work well in coastal areas in sandy soils without roots shells, rocks, etc. These sheet piles must be vibrated down rather than pile driven since they will shatter with a pile driver. To the best of my knowledge vibrating piling down in this soil is difficult if not impossible.

In coastal applications, sheet pile is usually put in the ground at least the same distance as is exposed above ground. Vinyl would work great if you set it in a 2' deep concrete footing with rip rap to protect the footing. Looks Great.

Per the manufacturer since my soil base is good old Alabama red dirt I would only have to trench a 4 foot deep trench about 12 inches wide. No need to vibrate into ground, only required for sand bases.

How do you know all this stuff? I believe you do but are you an engineer?, mad scientist?

Internet research and spoke with engineers at the manufacturer. They asked the same question - LOL.

we are in the process of completing a 1200 ft wall made of this material, with a 4' board walk. We dug a trench about two feet deep and drove the material into the lake bed with a backhoe about 4-6 more feet. only shattered 4 pieces of the stuff.

learned some things,
1 you cant use treated lumber from the big boxes, as it is not intended for ground or water contact.
2 the new treatment chemicals will distroy normal steel. you must use stainless or gavanized bolts and connectors..
3. you must put drains in the panels

1200 ft--Is that on Lake Martin--I'd love to see that when completed. Your luck with pushing vinyl sheet piling down is very good. Where can you still buy .40 and .80 treated material?

the wall is on lake martin. we will soon be back filling. we are currently installing a loop for a ground water heat pump in the area to be backfilled. we will also install wiring for lighting such as that used in swimming pools.

regarding the treated lumber. .80 CCA , I think that means .8 lbs of Chromate Copper Arsenate, is available from many sources but not for residential use. some suppliers, will not sell it to you for use in Lake Martin, although the last time I look, it was the milspec for al gov jobs.

that was my choice with rough cut lumber for the whales. at the end of the day, the rough cut would have taken to long to get. so I gave up.

i decided to go with CBA-A treated lumber in a concentration that would warrant the timbers for life with water contact. i believe that the concentration of that chemical in the wood i ordered was .28 or .32.

it seemed like the prudent thing to do, since i will be extinct in 25-30 years or will no longer care about seawalls.

you can get that type of wood at Lake Martin Building supply, or Alabama Wholesale Lumber. They both can order to your specs, as can any other supplier, if you get the right person on the phone.

CCA-A and CA-B treated lumber carries lables stapled to the end, that tells what the treatment is and if it is for ground and water contact. Most of the lumber sold by Home Depot and Lowes is not. BTW if you are ordering any significant amount of any material any building supplier will beat the big box guys.

The CCA-A treatment meant that I had to use stainless or galvanized fasteners. When we deck the board walk we will use composite lumber and matching ceramic coated screws. The ceramic coating is good for contact with lumber treated with CCA-A.

you are welcome to come see the wall at any time. any day that the weather permits I have people working to get it finished. it is located on point windy, about 1/4 of a mile past the condo's that they just built, but on the opposite side of the road.

Hey Maverick, my partner in our Lake Martin lakehouse is an engineer that used to sell vinyl seawall products and knows them inside and out. Send me an email if you want his contact information.

I have a vinyl seawall at my house near Real Island. I love it. The Power Co still requires rip rap though.
