Overview

Borrow-pit Investigations

Sourcing construction material efficiently can make or break an earthworks or roads budget. A borrow-pit investigation establishes both the quantity and quality of material available at a source — and what it will take to win and haul it.

Letaba Lab provides quantitative and qualitative borrow-pit reports that include layout maps, GPS coordinates, material profiles, overburden quantities, haul distances and accredited soil and material test results.

The result is a clear, full-colour report that lets you compare sources, plan haulage and confirm that material meets specification before you commit.
