Patio concrete slabs dropped

perda

Hi,

2 part concrete question:

part 1. my back patio concrete slabs have fallen quite a bit due to groundwater getting underneath. Have solved the water issue (hopefully) . Wanting to do decking over the top of the concrete slabs. Is it best to try and resurface the area with a concrete resurface or could you just put decking over it as is. Photo attached as reference . 

part 2. I have in the same area some concrete slabs for a walkway that have fallen toward the house/brick patio.. again, could I use a resurfaced to get the fall away from the house, or is it easier to do something else? Photo attached as reference 

** budget is an issue as cannot afford to remove and relay concrete **

Hello @perda,

Thank you for sharing your question about your patio concrete slabs. 

Yes, you can build your deck over the slab. It is vital that your water drainage be 100 percent effective. Any movement or sinking of the slab will affect the deck and move the footing of the frame located in that area. Resurfacing the slab will give you a flat surface to build from and will make the assembly of your deck much easier. 

Resurfacing the slabs that have fallen towards your house would be a good solution. It is affordable with a quick turnaround time and does not involve a complicated process. Once resurfaced make sure that the water drainage for this area is secure as well.
