I hope this post makes sense I will try and get photos in the next couple of days. In the mean time maybe you can share your thoughts.I looked at a previously installed paver walkway today. (installed 3 + years ago) The walkway is about 75 feet long with a slight slope. At the bottom of the slope is a door. The pavers in front of the door way have heaved so much that the door can no longer open.
1) The pavers were installed by a very reputable and qualified company so lets assume there is a proper base course.
2) The pavers are pitched slightly away from the door so water does not stand.
3)The pavers can not be re- installed with a greater pitch away from the door because of the surrounding asphalt height.
My question is how to solve this problem and why is it happening.
I know that when pavers are installed using a dry laid method they should be able to raise and lower with the freeze / thaw cycles so essentially they are working correctly but....
Do I remove the pavers and base and hope to find something wrong with the original install ?
Could water be running down the slope of the walkway under the pavers causing the problem?
Any Ideas ?
