Preliminary investigation

A preliminary investigation is required for stabilisation with GeoCrete®. During such an investigation we examine the soil and also check whether it contains any aggregates. This is necessary in order to determine the correct GeoCrete® cement-soil mixture. It is important to know: what are the properties of the soil components? The results of the laboratory tests are essential. They show which stabilisation mixture is required. This in turn gives a clear idea of the stabilisation costs.

During the preliminary investigation, laboratory tests are conducted with the untreated base material. These include examining the soil and determining the amounts of organic materials, granule sizes and Atterberg limits. Compressive strengths can be determined by creating proctors of various compositions.

Use & equipment

To guarantee top-quality results when using GeoCrete® for a structural or stabilisation project, it is important to use the correct tools. The equipment that is used must be suitable for the work. It does not necessarily need to be the latest equipment, but it must be suitable for the job in question. Our partners possess all the necessary knowledge and experience. They can assess whether you have the correct equipment. They can also advise you about any required repairs, spare parts or maintenance.

To guarantee quality results, you need the right tools – just as with any other job. The equipment must be suitable for the task at hand. The equipment does not necessarily have to be new and expensive, but you should make sure that it is ready for use and appropriate for the work to be done.
Terrastab technicians have the necessary knowledge and experience and can tell you whether you have the right equipment. They can check the equipment and advise you about any necessary repairs / spare parts or maintenance.

Design and life cycle

In many cases, the traditional design of the structure needs to be changed into a customised GeoCrete® design. In cooperation with an engineering firm, the results of the preliminary investigation can be incorporated into the design of the total structure. This lowers the costs, extends the life span of the structures and reduces maintenance and the risk of damage.

Training and supervision

During the stabilisation process, every step is in safe hands. We make sure of that at GeoCrete®. And that is why our partners are always present during the construction process. They guide you through the various steps. On site, they take care of the reporting tasks to make sure that the correct recipes for the structures are used. They are responsible for the homogeneous mixture quality, the correct mixture depth, the amount of water used and all the necessary quality inspections.

Terrastab can also be hired to train trainers and instruct personnel. They teach them how to use the specialist stabilisation equipment or to develop a technical awareness of the cold-mix recycling techniques. Because these are crucial for structures on every GeoCrete® job site.

Verification and delivery

As soon as a structural stabilisation has been implemented, there are a number of different methods available to assess the quality. Together with partners, TIMAB Industries supports the use of GeoCrete® for the correct application. Contact us!
