How can I secure a wooden privacy lattice into concrete without drill?

see above- same as pegboard... glue strips of wood first to concrete walls then screw your boards onto those strips

Hi Maleah Jo,

When I look at your pic, the first thing that came to my mind was to put decorative weights of some kind on both sides of the privacy screen. If it were me, I'd use plants on the front and maybe bricks on the back to hold it in place. You may have other thoughts about heavy items that you would like. The principle is the same. You might even dress-up the entire front side of the screen with a pretty indoor "garden" in pots. If you chose to use faux plants, just put bricks or some kind of weight in the bottom of the pot. I'd also make them as high as possible to really hold it securely. I hope this helps you. Wishing you the best!

Hi! Home Deepot has a great solution:

There are also planters, with trellises attached, so you could plant some vining plant like clematis or roses or honeysuckle, then let the greenery grow up the trellis. I've done this, and the plant greenery combined with the trellis (similar to the openwork at the top of your privacy screen) makes a very dense screen.

There were here already but had to take down the pegboard to get to the crack in the foundation that's how I know the wood strips (1x2" )were there ..home depot can suggest what type of glue I will also check with my handyman. Good Luck, Jean
