   I have a foundation for my new greenhouse that is not level and varies up to about 2 1/2 inches. I need to level it so I can bolt the outer sill to it every 3 feet and the inner sub structure that supports the whole thing every 6 feet. Would it be possible to pour a cap of concrete on top varying in thickness from about 1 inch up to 3 1/2 inches and keep it in place? Or would it be better to use a pressure treated 2x and shim then grout under? Or any other ideas? Thanks in advance.

   Hi Dixon,

   Yes it's quiet simple to add a concrete capping over your existing foundation. Clean the surface and apply a bonding agent prior to pouring. Use a pea stone mix or a sand mix cement if required.

   To make a good connection for your bottom plates, pre-drill the existing concrete and install anchor bolts and cast the concrete around them. Drilling them after the pour will risk your capping.
