What is on the left side of this pathway? Is it a wall? What's on the other side of the wall? What's on the right, is it a house? Is there a basement? Where is this located? Does it snow?

Does that downspout on the right side of the photo empty into this area? What other sources of water come to this area?

#1 thing to do is to reroute the water from the downspout to a drain, or to lengthen the pipe, either way to take the water away and downhill from this area.

You may also need to regrade away from the foundation on the right to lower the pathway at a slant so that water doesn't collect against the foundation. If that's a structure on the left, you may need to regrade both sides down to a gutter at a lower level in the center, that itself runs to a drain or runs out of this area.

You may also need a french drain in this area if it stays damp.

On the left is a brick retaining wall. On the right is a sunroom that was added to the house. In between is a paved pathway.

There are gutters on each corner of the sunroom. I think your suggestion to reroute the water from the downspout will be the best option. I have a rain barrel that I might could use at one of the downspouts.

We do not have a basement and it rarely snows here.

Should I apply sealant to prevent water from seeping under the foundation?

Thanks for your response.

Before offering more suggestions, understand that I'm just a fellow homeowner, not a contractor or a pro.

Rerouting the downspout flow will help, but to me how it is now contributes to the problem, but it's not the problem. Even with rerouting the downspout, rain will fall on this area and water will pool against the foundation.

What the problem appears to be is that the walkaway doesn't slant away from the foundation. It's hard to tell from the photo, but at best it's level, at worst it slopes into the foundation. .

To fix it may require taking up the concrete and putting in a slope that's high on right and lower on the left, with a gutter or drains on the left to carry water away from this area.

I'd call out a few landscape or concrete contractors and get professional recommendations.

Thanks. You have been very helpful. I have a landscape contractor booked.

Mudjacking is an unlikely approach. The technique is usually used when an area has sunk or needs to be leveled.

Cabot & Rowe...I looked this up on the Internet and this looks like what I need. Plus I can use this for the cracks in my driveway.

Thanks!
