Made Up Ground
Made up ground (also commonly called either fill or manmade ground) can be found where ground levels have been altered or features such as old quarries infilled. Where ground is made up in a controlled fashion using compacted layers it can have a good bearing capacity. Where ground levels are made up by simply infilling with soil excavated from elsewhere or waste materials the ground can have a low or variable bearing capacity. This can lead to a risk of both settlement and subsidence. These problems require careful investigation involving ground investigations and research of historical maps. Where terraced properties are built on this type of ground repairs need careful consideration to make sure that damage is not caused to adjacent properties.
