Trench backfill compaction prevents differential settlement that cracks pavement and damages utilities. Excavator-mounted compaction wheels apply concentrated ground pressure through rotating drums with projecting pads or smooth surfaces.
Padfoot wheels use projecting pads that concentrate ground pressure into small contact areas (30-60 PSI). These pads penetrate and knead cohesive soils (clay, silt), eliminating air voids. Padfoot is the standard for utility trench compaction.
Smooth drum wheels apply uniform pressure for granular soils (sand, gravel) where kneading is unnecessary. Sheepsfoot wheels use tapered projections for deep lift compaction.
The Compaction Wheel provides configurable pad patterns. The Vibratory Plate Compactor handles wider trenches. The Quick Coupler switches attachments. The Hydraulic Breaker pre-breaks oversize. The Ripper loosens compacted backfill.
