Borehole Package

Comprehensive deep investigation with SPT and laboratory analysis

Package Overview

The Borehole Package is BSGC's comprehensive investigation solution for projects requiring deep subsurface characterization. It includes rotary/percussion drilling with SPT sampling, rock core recovery, full laboratory testing, and detailed engineering recommendations. Ideal for multi-storey buildings, heavy infrastructure, and complex ground conditions.

What's Included in the Package

• Site survey and borehole location planning
• Rotary or percussion borehole drilling to specified depth
• Standard Penetration Testing (SPT) at 1.5m intervals
• Rock core recovery (where encountered)
• Undisturbed soil sample collection
• Comprehensive laboratory testing of all samples
• Detailed borehole logs and geological interpretation
• Geotechnical engineering analysis and recommendations
• Foundation design parameters and settlement analysis
• Comprehensive engineering report (20-30 pages)

Best For

• Multi-storey residential buildings (3+ stories)
• Commercial office buildings and complexes
• Industrial structures and factories
• Infrastructure projects (bridges, dams, roads)
• Deep pile foundation projects
• Complex geological conditions
• Sites with potential rock layers

Package Advantages

• Comprehensive: Complete subsurface characterization
