Compaction

Compaction equipment densifies soil, base, and asphalt so what gets built on top stays put. The category spans walk-behind plates and rammers for trenches and edges through ride-on drum rollers for roads and pads.

Fonctionnement

All compaction rearranges particles into a tighter matrix by applying repeated force: plates vibrate granular soils together, rammers knead cohesive clays with percussive blows, and rollers combine drum weight with vibration over large areas. Material is compacted in controlled lifts, layer by layer, and soil type dictates which force works.

Types et variantes

Compactors: Plates, rammers, and trench rollers for compacting confined areas and trenches.
Drum Rollers: Single and double drum ride-on rollers for soil and asphalt compaction.

Comment choisir

Two questions sort the category: what soil or material, and how much area. Granular soils take plates and smooth drums; cohesive clays take rammers, trench rollers, and padfoot drums. Confined work stays walk-behind; production areas justify ride-on rollers, with machine weight scaled to lift thickness and density spec.

Questions fréquentes

What is the difference between a compactor and a drum roller?

Scale and method. Walk-behind compactors (plates, rammers) work trenches, edges, and patches; drum rollers compact large areas from the seat, using drum weight and vibration over full lanes.

Which machine suits trench backfill?

Cohesive backfill takes a jumping jack rammer or trench roller; granular backfill takes a vibratory plate — always in thin lifts rather than one deep fill.

How does soil type change the equipment choice?

Vibration densifies sand and gravel but merely shakes clay; clay needs kneading impact. Matching force type to soil is the difference between passing density tests and chasing them.
