PRELIMINARY COMPARISON GUIDE
Vibro Stone Columns and CFA piles: ask better questions before selecting a route.
Both approaches may be considered in foundation projects, but they do different things and their viability depends on verified ground, loads, constraints and construction conditions. This guide explains the questions to bring into a competent technical review—not a method-selection rule.
Ground model: obtain suitable investigation information, including variability, water conditions and the depth/quality of supporting strata.
Performance objective: clarify the structural arrangement, loads and settlement criteria with the structural and geotechnical design team.
Construction effects: examine working platform, access, adjacent assets, vibration/noise sensitivity and programme alongside ground feasibility.
Decision boundary: confirm the actual design, execution and quality-control requirements through appointed competent professionals.
