2 ft garden wall - do I need footings?

Question

I want to put a 2 ft block wall with stone veneer around my patio. The patio is already 4" concrete. Can I just mortar the blocks to the edge of the patio, or do I have to dig/set new footings. (The wall is for decoration purposes and not going to be a retaining wall).

Answer 1

send me the measurements of the patio and I will send you a detailed plan with all the suplies that youi will ned. Thiss willl be at he lowest prices on the market. I wil chage you noyhing for my services

Answer 2

I would have thought if the supporting 4" patio is laid over a hard surface and well tamped (not soft ) it would not be a problem.

   two foot of blocks is not that heavy spread along an edge.

Answer 3

If the existing slab is sound (no cracks) you can mortar your blocks directly to the slab. The other stuff is absolute overkill for a short wall such as you describe.

Make sure the bond between all surfaces is sound (between mortar&block, mortar&slab, and stone veneer&mortar).  Clean the slab well, and make sure both slab and block are dampened slightly (no puddles) before buttering your blocks. Add a little acrylic fortifier (liquid at home supply store) to your mix.  This will not only strengthen your mortar, but also give good adhesion between all surfaces

Good luck.

Answer 4

You don't need footings per se - but you will need to dig down 3" to 4" add a sand and crush stone base and tamp really  well.  Pound a few re bar rods in to add some support and strength to your  wall.   Set you first course over a mortar bed and complete your wall.
