·           Clay soils are permanently modified by the addition of lime to a more granular material that can be readily compacted

·         A significant advantage of improving soils with lime products is the use of in situ materials

·         Eliminates the need to remove material off site and saves the cost of haulage and disposal

·         Reduces construction traffic by avoiding transport of excavated and imported materials

·         Considerably quicker to treat soils on site rather than to excavate, remove and import suitable replacement materials.

·         Different treatments are available to suit virtually every soil type and can produce a range of different strengths according to use

·         Treating materials with lime on site often has a positive impact on the construction programme
