Non vibration Stone Columns system
NON VIBRATION STONE COLUMNS SYSTEM
- Method opens up new foundation possibilities, where previously stone columns/ground improvement could not be considered due to vibrations and nuisance. Graded filter selected materials can be used so columns are more resistant to clogging in liquefaction events.
Columns remain effective for multiple events. - No introduction of high pressure water or air required so relatively mess free. Sites immediately adjacent to sensitive environments completed.
The tooling is a hybrid drilling assembly, this allows tool penetration through hard layers and removes the requirement for predrilling, that is often required for vibrating tooling. - Method builds complete columns at all times, so there is no-void space introduction to allow column contamination at any time, unlike methods where a plunging motion is used.
Patend assembly creates compact columns larger than the tool diameter (up to Ø 900 mm*) by compressing stone in the horizontal vertical directions, DURING THE EXTRACTION PHASE. - Fuel and Cost Savings on traditional stone column systems. No additional power packs are required, only one rig to perform the job.
Can be attached to a conventional rotary piling rig, thus a truly multi-purpose machine that can be converted back to other techniques is possible.
- The new ground improvement method is vibration free so it can be used immediately next to sensitive sites or neighbouring buildings
- Less power required
- Fuel savings
- Only two plant items required
- Fast to set up
- No high pressure water or air injection required therefore less mess
- Bottom feed – can be used in collapsing soils
- Binder can be introduced to provide rigid inclusions in the soil – no expensive concrete delivery trucks or pumps required
- No creation of liquefaction and possible machine instability due to vibrations
- No high wear and high maintenance high frequency vibrating parts
- Proven technique in a number of different soil types
- Recognised by international geotechnical engineering design companies

FEATURES
XP-2 SERIES
The XP-2 series uses hydraulic and electronic systems that directly control the hydraulic pumps to achieve efficient, precise and rapid results. The specialist components, along with the enhanced hydraulic layout, optimizes efficiency, leading to reduced load losses and fuel consumption.
CFM - CASAGRANDE FLEET MASTER
The fleet can be managed remotely via an online platform by PC, tablet or smartphone. This includes remote monitoring of any alarms and immediate diagnostics by the After Sales Service Team leading to significant reductions in intervention costs and rig downtime.
ASSISTANCE AND MONITORING
Operators benefit from automation of drilling functions, making the rigs user-friendly with complete control of the drilling process. The cab display provides real-time drilling data progress including depth, torque, pressure and verticality for operator control.
CDR - CASAGRANDE DATA RECORDER
CDR is available for all disciplines of piling and drilling and allows the rig operator to monitor the drilling progress on screen. Work parameters are recorded for subsequent analysis, or for site reports.
PERFORMANCE AND PRODUCTIVITY
The Smart Power Management (SPM) is an engine power management system that improves performance and productivity of the machinery. SPM monitors the power flows drawn from the engine and allocates the maximum available power to the required function.
COMFORT & TECHNOLOGY
The operator cabin is ergonomically designed for user comfort and soundproofing. Smart oil heat exchangers reduce fuel consumption and the overall noise level of the cooling system.
SAFETY AND MAINTENANCE
Hydraulic lifting canopy over the engine for easy access during inspections and maintenance. Optional stairs, platforms and railings provide safe accessibility to every point. Also, optional cameras and display for full visibility of the winches and working area.
ENVIRONMENT AWARENESS
Rigs are powered by the latest generation Stage V diesel engine with reduced exhaust emissions and use of low sulfuric content fuels. Further reduction of CO2 emissions is achievable by using HVO plant-based fuels. Bio-oils of high efficiency and performance are available.
