Ok .. last summer we had installed some pavers (a walk on both sides of house (one leads to porch other to back yd.) and then in between about a 10x15' area in front of garage door.- part of driveway. Well was at the neighbors house to bid and looked over and noticed the walk to back yard was settling... ? her downspout is pouring right on top of the pavers and looks like they are sinking. We put in a heavy heavy base on this job - due to the fact the area was once a swamp area or river many many years ago. But now it kind a look like sh*t, no call or complaint yet.. but sure its coming I know we should have ran drain under walk to avoid excess water.but didnt also notice (remember in mich concrete heaves and settles with the frost.. but the concrete area before the pavers on driveway is higher than pavers now. I am sure this will settle soon as frost leaves, and also this customer drives only on one side of drive to enter garage and somewhat looks like the area where tires run, are settleing as well, ( like a small rut) not really noticeable- but i notice everything. What the F. I worked on this project with crew and know what kinda base and excavation we did,, why is this goin on. Mich ground does suck! worst ever for roads, concrete and anything.. but i think if its installed solid it should withstand. Any suggestions or comments.?
