Many geotechnical problems are connected with the construction of highways, earth dams, buildings and other structures in or on moraine. In particular the densely compacted basal or lodgement tills cause major difficulties. The methods used at present to determine the geotechnical properties of till in situ or in the laboratory are uncertain and expensive. The contact pressures which are allowed for spread footings or caissons on till are very low, partly because of the often large variations of soil properties which occur within the construction site. For moraines the differential settlements are frequently of the same magnitude as the maximum settlement. The excavation of till is generally very time consuming and expensive, especially under water. Till is generally an excellent foundation material. Its bearing capacity is, as a rule, very high. The deformations are generally small, even at relatively high load levels. Some aspects of the classification of tills and the excavation and compaction of till when used as a construction material are reviewed. It should, however, be pointed out that relatively little is known about the physical properties of till in comparison with such soils as clay, silt, sand and gravel. /TRRL/
