Clay heave simulation

British Geological Survey During this video we can see the effect of a clay swelling due to water ingress and the subsequent damage to the house above. This hazard is known as heave and is associated with the shrinking and swelling properties of clays. This tends to be a problem […]

Quicksand simulation

British Geological Survey Here, our lifeguard is about to experience quicksand conditions. Water is pumped in from the bottom of the model to simulate a spring, artesian condition or incoming tide, that may result in sand grains floating and quicksand to develop locally; the effect can be transient and change […]

What is Geotechnical Engineering?

Geotechnical engineering is the branch of civil engineering concerned with the engineering behavior of earth materials. Geotechnical engineering is important in civil engineering, but also has applications in military, mining, petroleum and other engineering disciplines that are concerned with construction occurring on the surface or within the ground. Geotechnical engineering […]
