Here’s a more polished and professional version that keeps the concern clear and invites informed opinions:
Is this patio going to be too high? I’m looking for some experienced opinions before the concrete is poured. 🏠🔨
We’re having a 30' × 35' concrete patio installed, and our yard has a significant slope. Before construction began, the contractor assured us that he would be able to properly level the area. However, this is the current base he is planning to pour the concrete over.
He has explained that he will add another board along the back edge and install mesh reinforcement in the concrete. My concern, however, is the amount of elevation above the surrounding grade. In some areas, the proposed patio edge appears to be more than 20 inches above the existing ground.
I understand that concrete itself is strong, but my concern is whether the underlying base and the exposed edge are being properly supported. With that much elevation change, it seems like drainage, soil support, compaction, and some form of retaining structure may need to be considered.
The contractor says the concrete is already scheduled for Friday and that the pour cannot be canceled.
We’ve discussed several possible solutions, including installing a retaining wall or bringing in additional properly compacted fill to raise and level the surrounding yard. Either option would require additional time and expense if done correctly.
Would you proceed with the pour as it is, or would you stop and address the elevation and supporting structure first?
I’d especially appreciate opinions from experienced concrete contractors, excavators, or builders who have worked on patios with significant grade changes.
Are we being overly cautious, or are there legitimate concerns that should be resolved before the concrete is placed?
