The company has been built upon sound technical and operational expertise, in the Ground Improvement Industry, with over 30 years experience. Our reputation is steadily growing as an outstanding company for customer service, geotechnical and engineering solutions, to provide the customer with the most economic and technically correct solution to your problem, “whether the site requires treatment or not we will tell you”. For a solid solution to your problem with specialists with the flexibility to look out side of the box, come to IGI Ltd.
Services
IGI provides a comprehensive package from the initial interpretation of site conditions, design of the foundation solution, through to completed ground improvement solutions. With a number of ties with companies providing differing solutions to the problem in the ground, we are confident we can provide you with a valued engineering concept and designs to move the ground to stability.
We can provide the following solutions:
- Vibro Displacement
- Dynamic Compaction
- Soil Stabilisation
- Ground Remediation/Solidification
- Earth Moving
- Piling
What We Do
Independent Ground Improvement Company Limited (IGI Ltd) is the up and coming force in the Ground Improvement sector of ground engineering, becoming renowned for providing innovative and technically advanced solutions to problems in a cost effective way. We pride ourselves on the fact that if a job does not require treatment - we will let you know.
We are a small company, which prides itself on providing solutions with a personal touch, keeping a close working relationship with clients, main contractors and structural/consulting engineers. This has been shown by the high level of repeat business that the company experiences.
We are solely based within the United Kingdom, with our offices within Risley, Warrington, but able to service any enquiry or work within the United Kingdom. Our engineers have a wealth of experience, as do our site operatives, who can therefore can advise on all aspects of ground improvement design to site-based operations.
Vibro Displacement
The use of vibro displacement (stone columns) relies heavily upon the soil properties of the material to be improved.
The soil must be appraised in terms of:
- Type (cohesive/granular/intermediate)
- Soil Description (Clay/Sand/Gravel/Peat/Fill)
- Strength/density (ability to provide lateral stability for the stone column)
- Swell/Heave potential
- Water Content/Standing Water Level
- Granular Soils Treatment - vibration increases the density by reduction of the void ratio of the granular soils. The vibrations act to overcome the frictional contacts (effective stress) between the soil particles, and forms a state of greater relative density
- Cohesive Soils Treatment - reduces pore water pressure therefore increasing effective stress (strength). The cohesive soils also confine the stone column and this passive resistance allows the dense granular column to reinforce the soil.
This is carried out by the following procedures:
- Vibro Rig displaces the soil by vibrating a mandrel into the ground to the required depth or refusal, whichever is achieved first.
- The mandrel is withdrawn and the subsequent void filled with a clean stone. The stone is generally a 40mm - 75mm clean quarried material, however other sources of materials can be used (crushed concrete, screened railway ballast)
- The mandrel is then reintroduced to the in-filled void and taken down to close to the base of the previously formed void, displacing the stone laterally into the surrounding soil. The process is repeated with subsequent filling and compaction of the stone to form a vertical stone column, with close interlocking into the surrounding soils.
- This method provides the ground with the ability of increased load bearing characteristics.
