Why does the base matter for pavers on red clay?
The base matters more than the paver. Red clay swells when wet and shrinks when dry, and it holds water instead of letting it drain. A patio laid on a thin base will settle, rock or grow low spots where puddles form.
A sound paver job usually includes these steps:
- Dig out the topsoil and soft clay to the depth the design needs.
- Lay and compact crushed stone in layers. Several inches is common for patios and walks, and more for driveways or soft ground.
- Add a thin bed of bedding sand and set the pavers with a slight slope so water runs away from the house.
- Install edge restraints so the pavers cannot spread.
- Sweep in joint sand and compact the surface.
Skipping a step is how patios fail. Ask any contractor how deep the base will be and how the surface will drain.
