Can I hang a kayak on a retaining wall.


I have a 14' high retaining wall made out of Keystone standard blocks.
http://www.keystonewalls.com/pages/p.../Standard.html
Can I screw a couple hooks to it and hang a 60 pound on them?

Seems like it ought to be safe enough, but considering how expensive the wall was, I don't want to make any chances.

I think your best bet is to contact Keystone directly and inquire from them. If allowed they would be able to tell you how to anchor your hooks. I believe anyone else would be guessing, I know I would be.

Good luck!

i'll guess its the 1st time they've been asked if 1 hook into a block would hold 30#,,,IF it were my kayak, it'd already be hung & i'd be back on the couch

I wouldn't, due to you do not know if the person that put up the wall with that system, did it correctly. You are better to just build a rack out of pressure treated lumber, that you can place the kayak upside down on, and secure with a chain or cable, to keep it from walking away.

Also, do you not have a storage area if this is a rental, that you can place the kayak in, or a carport/garage, where you can place it out of the way?

The Keystone system, like most segmental concrete block walls over 4 feet tall, relies on reinforcing that extends backwards perpendicular to the wall face. The concrete blocks actually provide very little support, they are there mostly as an attractive face on the wall, and provide a place to terminate the reinforcing fabric that strengthens the soil.

As such, the blocks are certainly not intended to support the type of load you are discussing, as a kayak would exert rotational forces on the block. I would send Keystone a sketch of what you have in mind, see what they have to say.

If I ask Keystone they will tell me the product was not intended for that purpose and has not been tested for it. They would recommend against using it for anything but the intended purpose.

Each block is connected to the one above and below it by two fiberglass pins.
A block shouldn't twist out, and each block weighs more than the kayak; but if it did fail...
If the proposal is to be believed, they brought in 600 tons of material to create the terrace; the DEC wouldn't be happy if that fell into the lake.
I wonder how stable it would be if the wall was removed.

well I doubt they would have put up the retaining wall if it would have been stable without it. Make sense?

I would ask Keystone "how do you anchor a couple of hooks into their product to hang your kayak from," not if they recommend it .... now they may answer you with "we don't recommend it"

I had to go check, and make sure I was really on the right forum after reading some of these answers. Shoot, after even reading just the question!

I did ask Keystone. They didn't discourage me, but said to use concrete anchors rather than screws, as there are likely to be voids that screws won't hold in.

What, the pic's were not enough to show that there are voids in the blocks? If you do use anchors, use the types that are used for securing block foundations in the soil, when they bow.
