Description

Traditional WOOD Core Blocks

Our Wood Core Blocks are the long-established industry standard for marking depths and drill-hole information in geotechnical core trays. These blocks provide a practical and cost-effective solution for identifying run breaks and critical sampling intervals. Each block is manufactured with a smooth, finished surface, making it ideal for writing clear, legible notes with permanent markers or paint pens directly in the field.

Universal Profile & Design

Engineered for versatility across various tray types and drilling programs:

  • Dual-Surface Geometry: Featuring one flat and one angled surface, these blocks are designed to fit securely into both round-bottom and square-bottom core trays.
  • Reliable Marking: The natural wood grain is processed to a smooth finish to prevent ink bleeding, ensuring that drill hole IDs and meterage remain sharp and readable.
  • Durable Construction: Made from quality timber to withstand the moisture and handling typically found in core logging sheds and outdoor storage environments.
