100 kg Soil Compactors

100 kg Soil Plate Compactor — Definition and Use

A 100 kg soil plate compactor (forward-only vibratory plate) is a machine with an operating weight of roughly 90–120 kg that compacts loose soil and aggregate layers through the vibration of a steel plate, moving forward only. An exciter with a rotating eccentric shaft generates a centrifugal force of around 15–25 kN, transferred to the base plate, which tamps material into a layer roughly 15–25 cm thick over several passes. This is the middle tier of the forward-plate segment — heavier than light paving-stone models (around 60–70 kg), lighter than machines at the edge of the reversible segment (around 130–160 kg).

The 100 kg class suits sub-bases for paving stones, footpaths, driveways and perimeter strips around buildings. At NORWIT.PL this class is led primarily by Wacker Neuson, Altrad Belle and Bomag machines, plus further manufacturers.

The 100 kg Class Against Light and Heavy Forward Plate Compactors

Forward plate compactors are split into weight segments, and each corresponds to a different layer thickness. The 100 kg class sits in the middle of the range — heavier than models built purely for paving stones, lighter than machines at the upper edge of the segment. See the full overview of types and weights in the soil compactors category.

The right segment depends on layer thickness and soil type: cohesionless soil (sand, gravel) responds well to vibration, while cohesive soil (clay, loam) needs a rammer.

Popular 100 kg Plate Compactor Models at NORWIT.PL

Below is a cross-section of 100 kg class models at NORWIT.PL — all operate in forward-only mode; exact specifications are on the individual product pages.

Wacker Neuson equipment offers the widest range in this class, Altrad Belle machines in the PCEL and PCLX series are valued for a good price-to-quality ratio, and the class is rounded out by Bomag plate compactors.

Technical Parameters of the 100 kg Class

Three parameters govern compaction performance: centrifugal force, vibration frequency and travel speed. In the 100 kg class, centrifugal force typically falls in the 15–25 kN range, generated at a vibration frequency of roughly 70–100 Hz — it is this force that breaks resistance between aggregate grains and drives the machine forward. Travel speed is usually around 20–25 m/min, with a plate width of roughly 40–45 cm.

Effective compaction depth is around 15–25 cm of loose layer per cycle, typically with 3–4 passes over the same surface. Soil is laid and compacted in stages of 10–15 cm — trying to compact a thicker layer in one go leaves the bottom portion under-compacted.

Forward or Reversible Plate Compactor in the 100 kg Class

The 100 kg class is dominated by forward plate compactors — machines that move only forward, which the operator turns around by hand at the edge of the working area. This layout is simpler to operate and cheaper to service. A reversible plate compactor works in both directions, starts at heavier weights and compacts thicker layers — 30 cm and above — but needs more room to manoeuvre. For domestic work and sub-bases under paving stones, the forward-only 100 kg class is usually enough; roadworks call for a reversible model.

100 kg Plate Compactor for Paving Stones — Protective Mat

A 100 kg class plate compactor handles both the sub-base for paving stones (a 15–20 cm aggregate layer) and the final tamping of the laid surface itself. Working on finished paving stones, however, requires a protective mat — a rubber or polyurethane pad a few to a dozen millimetres thick, fitted under the plate. Without a mat, a machine weighing 90–120 kg with a force of 15–25 kN can scratch the surface or chip the paver edges as early as the first pass.

The mat is matched to the plate width of the model; for the sub-base alone, before the paving stones go down, you can work without one. Sets that include a mat are available in the plate compactors for paving stones category.

Engine, Starting and Price of a 100 kg Soil Plate Compactor

100 kg class plate compactors come with a recoil (pull) start or, from some manufacturers, an electric starter offered as an option. The exact drive type of a given model is stated in the specification on the product page. The machines need engine servicing (oil, filter, spark plug) and exciter maintenance; the first inspection falls around 20 hours of use, then every 100 hours.

Price depends on brand, starter type and equipment, typically several thousand to just over ten thousand PLN net — electric-starter models usually cost more. Current pricing and availability for a given Wacker Neuson, Altrad Belle or Bomag model is shown on the product page.

Frequently Asked Questions About 100 kg Soil Plate Compactors

Why Buy a 100 kg Plate Compactor at NORWIT.PL

In the 100 kg class we carry primarily Wacker Neuson, Altrad Belle and Bomag machines, complemented by further manufacturers. We advise on matching the segment to soil type and layer thickness: lighter forward plate compactors suit thinner layers, a reversible plate compactor suits thicker sub-bases. We provide servicing and accessories in our plate compactor accessories range. See the full offering in the soil compactors category, and mat-equipped sets in plate compactors for paving stones. Orders are fulfilled online, with nationwide delivery.
