Introduction – why compaction matters

Getting the sub-base and laying course properly compacted is essential for long-lasting patios, driveways and paths. If you skip or under-compact, stones move, slabs settle and all types of surfacing can fail prematurely. The right compactor ensures uniform densification, prevents future subsidence and gives a stable base for block paving or asphalt.

Types of compaction equipment at GR8

At GR8 we supply several compaction tools for different tasks:

• Vibrating plate compactors (wacker plates) – the go-to choice for general sub-base compaction under patios, drives and paths.
• Trench rammers – for narrow, deep or confined trench areas where a full plate won’t reach.
• Power floats / finishing trowels – used for creating a smooth concrete surface finish, not for sub-base compaction (so we don’t use them for base layers).

How to choose the right plate size

Wacker plate compactor sizes are often described by plate width (e.g. 12-inch, 16-inch). A wider plate covers more area per pass but may be harder to manoeuvre in tight or tricky areas. Use these general guidelines:

• 12-inch – ideal for tight spaces, steps, small patios or awkward corners.
• 16-inch to 18-inch – suitable for most garden paths, single-car driveways and general paving areas.
• 20-inch – best for large patios, double driveways or when you want to reduce the number of passes on large flat areas.

Beyond width, consider:

• Material being compacted – if compacting a Type 1 sub-base (crushed stone), you may need more energy (heavier or more powerful plate). For sharp sand under block paving a moderate plate is usually fine.
• Access constraints – gates, narrow paths or awkward edges may force you to use a smaller plate even if a larger one is more efficient elsewhere.
• Edge finishing and detail work – close to walls, edges or corners, you often need to back up with a smaller machine or hand-tamp borders.
• Operator fatigue – bigger, heavier plates are harder to control and steer over time, especially on uneven ground.

Here’s a simple decision table to guide your choice:

In practice you may combine sizes: for example, use a 20-inch for the bulk of a driveway, then finish edges or corners with a 12-inch or even a trench rammer.

Safety tips and accessories

Safe operation is key. Always observe the manufacturer’s guidance and the following best practices:

• Wear PPE: gloves, ear protection, eye protection, and steel-toe boots.
• Start the plate on level ground; avoid starting on slope edges or unstable surfaces.
• Maintain stable footing, work with your body aligned, don’t overreach.
• Be aware of vibration exposure—limit continuous use and allow breaks.
• Avoid operating on steep slopes; if necessary, work across the slope, not directly up/down.
• Mark underground utilities before compaction; avoid unknown pipes or cables.
• Remove high spots or stones that protrude before running the plate.
• For block paving, lightly dampen the sand layer (not wet) before compaction to help lock grains in place.

Useful accessories you might also hire:

• Wacker Neuson vibrating poker – useful for consolidating fresh concrete where slabs or infills are involved.
• Trench rammer – essential for deep narrow trenches or around foundations.
• Edge boards or timber restraint (you should bring or request these) – helps contain material while compacting to edges.

Quick checklist

• Measure total area to compact
• Note access width (gates, doors) and tight spots
• Decide base material (Type 1, sand, asphalt)
• Check the product pages for plate sizes and rates
• Plan for edges, corners and utility locations

FAQs

Do I need a wacker plate for block paving?
Yes — a plate compactor is vital to consolidate the sub-base and sand before laying units, and to final compact after infilling. It ensures stability and prevents movement.

Which plate size for a single-car driveway?
An 18-inch plate is usually a good choice for a single-car driveway, balancing coverage speed with manoeuvrability. If the driveway is flat and open, a 20-inch might also work.

Can I compact Type 1 in wet weather?
It’s best to avoid compaction when the base is saturated—excess water obstructs compaction and causes instability. Aim for moist but not soggy conditions.

How many passes should I do?
Generally 2–4 passes are common, but you may need more for deeper layers. Watch for “stops” or deflection — when further passes don’t change the surface, you’ve reached adequate compaction.

What PPE do I need?
You should use gloves, ear and eye protection, and sturdy boots. Also limit exposure to vibration and follow manufacturer guidance on maximum continuous run intervals.

Note: prolonged vibration can lead to hand-arm vibration syndrome (HAVS). Always follow the manufacturer’s maximum exposure times and allow your operator rest breaks. For complex or steep sites, contact GR8 for specific advice.
