Growing a lawn on top of a backyard slab?

Hi there, I want to grow some lawn in my backyard, but it is completely concreted over. I want to raise an area by 2 brick heights then put soil then roll out lawn on top of this. Will this work? I’m worried about drainage and wondered if anyone had any suggestions. I don’t want to end up with a swimming pool. I live in an area where we have drought then terrential downpours.

Think of this as a planter. If you’re setting the bricks in mortar (cement) then you’ll need to provide drainage at intervals around the base by omitting the mortar between two of the bottom bricks every several feet. If the bricks are loosely laid than this is not necessary although the brick will tend to shift out of place.

I don’t think two brick height will do it for you. Your planter should be at least 12" to 18" deep to support grass during dry periods and even then you will need to water frequently. By "roll out" I take it to mean you are laying sod so your "torrential" rain shouldn’t bother it.

  1. You could perhaps may the bricks sloping so the water runs off instead of creating a puddle

  2. Consult someone who works at lowes.

  3. Have someon come in with a back hoe and remove the concrete. Dig a drainage ditch around the area. Put in drainage pipe and coarse gravel. Then put down loam to the desired depth and seed it.
