I have a concrete walkway that has sunk qnd now is causing me issues with the water pooling.

Im considering removing it, regrading and replacing it with gravel. Will the exposed spot now take on more water than before when it was pooling there?

Well, gravel absorbs moisture, so unless you create a mound first with backfill and then gravel it, yeah... it's going to be a sloppy hole.

Why not remove the concrete, regrade, pack it down good with a compacted rock base, and repour the walkway? As long as the concrete is higher you will be high and dry.

 

Mudjacking would potentially be another option.

 

Where is the water coming from? If off of the house would rerouting the downspouts so the water is carried to a different location help? Has the sidewalk indeed sunk or has the ground next to it gotten built up over time?

 

Its actually in a location where replacing it with pavers would look good. However the section would be surround by concrete in all directions... would the run off from the concrete saturate the area?

 

Heres some photos of what I am trying to describe.

The water collects where the slab sunk in front of the bulkhead. I am getting seepage down in the bulkhead and Im thinking this is the reason.

I could use a whole new driveway etc but thats not possible.

How should I go about this?

 

How deep does the water get? If it's coming over the top that is one issue but if it's seeping in thru the sides you'd remove the pavers and dig down until you can seal it up properly. If water gets deep enough to come in thru the top you need to work on stopping the water before it gets to that point.

 

The slab that sunk is sloped away from the bulkhead and the water accumulates in the pocket where the two pieces butt against each other. The water puddles to about 3 inches in that pocket between the relief joints. It will saturate into the ground over time unless I sweep it out.

The large slab to the left (garage side) slopes to the center into that pocket and the other two large slabs on either side of the bulkhead also slopes to the center (away from the house).

Maybe that explains the seepage, we do have an active sump in the springtime so maybe just the water table is high. Its all surrounded by concrete, so I assume that leans more towards the natural water tabel vs. rain runoff.
