For site investigation technicians who need a reliable personal supply of borehole log sheets on every job, the A4 Drilling Log Book in a 50-set pack is the practical field choice. Compact enough to carry in a site bag, this pack gives an individual technician a full season's worth of borehole recording capacity without the need to requisition books from a stores department or rely on shared site supplies.

Each set produces three legible copies simultaneously using NCR (No Carbon Required) paper — one for the site file, one for the client, and one for the office — with no photocopying required and no risk of illegible carbon transfer. The preprinted A4 format follows standard borehole log field layouts, covering all information required under BS 5930 for cable percussion, rotary, and windowless sampling operations.

Built for daily site use, the durable cover protects sheets in the field conditions typical of UK ground investigation work — wet ground, muddy hands, and site vehicles. At 50 sets, this pack is sized for individual purchase or topping up a personal supply mid-project.

Key features:

• A4 format — standard for UK borehole logging
• 3-part NCR triplicate — one write, three copies
• 50 sets per pack — individual technician supply
• Preprinted log fields for BS 5930-compliant recording
• Durable cover for field conditions
