Pavers that sink, dip or form puddles after rain
- What actually happened
- The base was never compacted to the right density, or it was built on unscreened fill. Every rain cycle washes fines out of the sub-base and the surface drops into the void left behind.
- What a correct install does
- A base compacted in lifts to 95% Proctor over a geotextile separation layer, so the sub-grade and base never mix.
- How it gets fixed properly
- Lift the field, rebuild and re-compact the base in lifts, correct the sub-grade slope, then relay. Re-sanding the joints alone hides the dip for one season and it comes back.
