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.
