Clegg Hammer Compaction Testing Services

At All Grass Solutions, we go beyond basic turf maintenance. Unlike most lawn and sports field care providers, we offer quantifiable results by measuring the effectiveness of our renovation and aeration techniques using our in-house 2.25kg Clegg Hammer.

Whether you’re managing a professional sports field or school oval, compaction testing is essential to ensure safety and performance.

What Is a Clegg Hammer?

A Clegg Hammer is a specialised device used to measure the impact hardness of soil or turf surfaces. It provides accurate data on surface compaction levels, which directly impact:

  • Player safety
  • Turf performance
  • Water infiltration and drainage
  • Turf recovery after wear

This testing is essential for sports fields and high-use turf areas to assess whether the surface is safe for use or poses a risk of injury, particularly to lower limbs or from falls.

Why Compaction Testing Matters

Over time, natural surfaces become compacted due to heavy foot traffic, machinery, and environmental factors. Compacted turf:

  • Reduces air and water flow to roots
  • Limits turf growth and recovery
  • Increases risk of injuries during sport or recreation
  • Leads to poor playing performance

Aeration is often the solution—but how do you know when it’s needed? That’s where the Clegg Hammer test comes in.

Trusted Data for Safer Play

Surface compaction is a key factor in sports field safety. Research shows that reducing compaction through proper aeration can lower the risk of lower limb and head injuries. Our Clegg Hammer testing helps ensure your surfaces are not only healthy but safe for athletes, students, and animals.

Surfaces We Test

Our Clegg Hammer testing can be used on a wide range of natural surfaces, including:

  • ⚽ Soccer fields
  • 🏉 Rugby league fields
  • 🏏 Cricket pitches
  • 🏫 School ovals and playgrounds
  • 🐎 Horse tracks and equestrian arenas

How It Works

  • Step 1: Our technician drops the 2.25kg Clegg Hammer from a standardised height.
  • Step 2: The device measures the deceleration (measured in Gmax) as it hits the surface.
  • Step 3: Results are recorded, interpreted, and compared against recognised safety benchmarks.
  • Step 4: We provide a report and recommend any necessary turf treatments.
