Soil compaction

Soil compaction affects whether pavers settle, turf wrinkles, slabs crack, and retaining walls move. It is especially important on fill soil, slopes, wet sites, and heavy-use surfaces.

Definition

Soil compaction is the process of mechanically densifying soil or base material so it can support hardscape, turf, slabs, driveways, walls, or structures.

Why it matters

A strong bid should specify excavation depth, aggregate layers, compaction method, lifts, fabric if needed, and what happens if unstable soil is found.
