    Got to bid on back filling a sea wall approximately 155 feet. This last season of hurricane pushed water over the top and washed out the sand & turf about 8" deep and extends about 1 foot away from the wall.The sea wall is concrete and extends approximately 4 feet below the water line (water is about 18" deep) now liner is present even though this wall was built last year.What is the best and or proper way to fix this? Thanks

    Can you get a few pics of this?Better to help you with pics of it.Sounds just by discription that the whole wall needs to be taller.

    Will get some pics to night, should have mentioned that this sea wall is on a lake. I believe the best plan of action is just to back fill with sand, compact and re sod. Any one know the ratio for cubic foot to a yard?

    If you just backfill with sand it will wash right back out over time.

    from the way it "sounds" the wall was not back filled correct to start with. Unless the water level was over the wall and the wave action over the top just took some of the top soil.

    If it truly "washed out" like under the wall then you need to get a backhoe dig it out the back fill it corectly. If you are unsure of how to do this you need to find someone that knowns what to do or you could make a real mess

    After thought:
    thinking about it those lakes down there have a lot of muck around them some house pads around Lake June had to be dug 20+ foot deep and back filled to build a house. The muck behind and below the sea would could have settled with the water over it. The only way to know is with a test hole to see what is down there. It may be back filled correct and just need some drit added to the top to take up for the settling below. If the tes hole shows it is ok compat what it ther and fill in layes ad you compact.
    if there is muck down there the will have problems from now on no matter what you do
