What would be the best way to raise my pool shelf? I messed up and set grade at the pool house and I should’ve done it at the main house. I thought they were same grade but obviously now. For the flat parts of shallow and deep end and slope I’m having concrete poured and troweled smooth so I can add rock in the main pool. I guess the main question is what’s the best way to raise the walls up? I’m needing to gain maybe 2-3”. The way it sits now the finished concrete will about the same height as my current poured patio. I am putting in deck drains but I’m afraid if same height with a heavy rain, a lot of water may make it into the pool. The space between pool at current poured concrete is 4’.
