Water pooling on newly installed paver patio

3 years ago

The paver patio got installed last week. Other landscaping work is still on going.

Today we discovered a bigger issue....After the landscapers were gone for the day, we decided to wash the paver patio as it was looking really dirty/muddy. We washed it with a hose and there are multiple spots were water pooled.

Please see pics and tell me if this is reason to be concerned or not. We only ran water for a few minutes and when I went back after may be 20-25 mins, there were still little water remaining over multiple spots.

I want to say though, this crew has been so hardworking. They have put so much hours into this, its just so sad they wouldn't test along the way and might have to spend as much hours fixing it.

Please note they did install french drain throughout the backyard and around the back perimeter of this patio as well.

Before pics below.

I went back after about 20mins and here where they were at. Below:

What did the landscaper say about it?

Why are a few slightly low spots an issue?

What are they sitting on? What happens when others move slightly and create more low spots, or maybe some raise a bit making it look like others have sunk.

From my perspective (limited/photo), it looks like there is a lack of slope. I had a large paver patio at my last house and my landscaper was very careful to give it slope which was challenging given the size.

My pavers were smaller and varied in size. With large pavers, slope is harder to hide - as you have. Also, being up against the house limits options. The house is not sloped because that would be unsightly and it wasn't designed as a patio which limits the slope in those planes. That being said, it would stll seem doable. Although I think that corner of the house, it will be visually noticeable.

I think - though I can't know for sure - that you need more slope. Get a 3 or 4 foot level and place it on the patio. It should slope away from the house. Otherwise it could be a foundation issue.

Pavers are not permeable. The spaces in between are not really to allow water to pass. Water will pool unless they are sloped. You may not like the visual of the slope but it is necessary.

I agree with David: possibly a lack of a proper slope. We had a large backyard paved patio and front walkway installed a few years ago, and the landscape did a proper slope. No water collecting issues.

Picture #3 - it looks like the aggregate is not evenly tamped and that there could air pockets beneath the pavers in that last row. Did they use sand below the pavers? Maybe it's just the angle of the photo, but the grading looks pretty funky.
