Scheme: New Timber Processing Plant 
Client: TaylorMade Timber 
Process: Cement Stabilisation to Clay 
In-Situ Process: Cement Satbilisation 
Explanation of work completed:  
Taylor Made timber appointed a sub-contractor to undertake a large cut and fill project on their behalf to extend the yard and provide for more space for new processing equipment to keep up with demand for their products. 
The cut and fill project involved using site won materials and some imported materials to build up the site and there was a need to improve the strength of the site won materials to achieve a suitable CBR before laying down a Geogrid and putting in new quarried stone aggregates to a depth of 300mm in preparation for wet laying concrete over the full area of 7,000m2. 
RTW were brought in by the sub-contractor to provide advice for treating the site with materials to be able to achieve a high strength CBR before the laying of the Geogrid and quarried stone. 
Firstly, a geotechnical company were appointed to take samples of the materials and undertake testing, cubes at varying percentages were made to make sure we could achieve a minimum of a 15% CBR plus. From these tests carried out RTW could confirm the amount of bulk cement powder that would be required to treat 2 layers of the site won material at 300mm per layer. 
Once this was agreed with the client and sub-contractor RTW worked with the sub-contractor to treat the materials in the 2 layers at 300mm per layer after each layer was treated the material was graded with the use of a dozer using GPS to achieve the correct levels and the sub-contractor could then import more materials for the second layer to be treated. The same process was repeated on the second layer to achieve a suitable base for the geogrid and quarried stone. 
This process saved the client money and time by been able to use materials he already had, and stabilising materials is quicker than importing quarried stone. The Carbon footprint of the scheme was dramatically reduced by completing this process as well.
