When do you need a CBR test?
A Flood Risk Assessment is compiled using third party data sources. These can include data from the Environment Agency modelling, or independent data collected by the consultant or EMS Geotech. An analysis of the data sets will be undertaken to get a full overview of the site and any associated flood related risks identified.
The purpose of foundations is to transfer loads from a structure to competent soil/rock. They come in the form of traditional shallow spread foundations (strips, pads and rafts) or deep foundations (piles and ground improvement). The main factors influencing foundation design is the stability of the underlying ground and settlement.
Foundation depths will be influenced by the strength of the ground, seasonal moisture variations, the effects of tree roots, frost action, river erosion, groundwater elevation and buried structures / ground disturbance.
