Why do pavers sink or shift on Miami ground?
Almost every failed paver job traces back to what is under the pavers, not the pavers themselves. Miami lots often sit on fill or thin sandy soil over limestone, and the summer rains are heavy. If the base is thin, poorly compacted or sits where water collects, the surface settles in a season or two.
A sound installation usually includes:
- Excavating to the right depth and removing soft or organic material
- A compacted base of crushed rock or limestone base material, built up in layers
- A screeded bedding layer of sand, kept thin and even
- Edge restraints, so the outer pavers cannot spread
- Joint sand swept in and compacted, then topped up after the first rains
Slope matters as well. A patio should fall gently away from the house so storm water runs off the surface instead of toward the slab. Ask any contractor how they plan the base and the slope. A clear answer is a good sign.
