Building a ball wall

I am looking for plans for constructing a ball wall. Do you have any plans or suggestions? (It will need to be a wood wall, not a concrete/cinder-block wall)

Answer
I dont have any plans available for building a wall, but I would love for someone who is a contractor or engineer to submit some.

I would like to start by saying I always prefer concrete or brick to wood, but if your only choice is wood, I have seen or heard of two basic types of walls that do work fine with care and good construction.

The better but heavier and more expensive of the two is where you stack 2x4's or 4x4's on top of each other length wise with 4/4 or 4x6 support behind them. This builds a very tough and heavy wood wall that can be surfaced with hardboard or high density marine plywood to give it a smooth finish. I have also heard of people using other things like aluminum sheeting or steel to cover their wood wall to give a more durable and hard smooth surface.

The other walls I have seen are only surfaced in a couple layers of plywood. You have to use very good hard wood like birch or other hard wood high density plywood for the surface because the balls take their toll and all wood should be treated to fight water damage. There are some nice hardboard high density particle boards as well that work great. Check with your wood supplier for suggestions.

Please make sure you are setting your walls safely. The very last thing you want to do is crush a kid because you built a poor wall. Make sure the wall is properly anchored into the ground using concrete and posts. Tied down against the wind and supported from behind.

If there are any contractors out there who would like to share your thoughts and design tips please share.
