What is heave in a house? Heave is the phenomenon of the soil beneath a property expanding and pushing the ground upwards, which can cause structural damage to a building. Ground heave is the opposite of subsidence, which is when the ground sinks.

What causes heave in a house? Ground heave occurs when the ground beneath a building moves upwards, i.e. the opposite of subsidence. Heave is caused by the expansion of the ground, and is usually associated with clay soils which swell when they get wet. Heave can cause significant damage to building foundations and structure.

What heave looks like? Common signs of ground heave may include: Cracking to brickwork and windows. This cracking is more likely to be vertical, whereas subsidence cracking is more likely to be diagonal. Doors sticking as their frames become out of square.

Is heave covered by insurance? Heave is generally covered by most home insurance policies, but the excess, as with subsidence, is usually set higher than for more ordinary claims as the work that’s needed to correct it is usually much more costly.

What is a heave or lift?

A lift is a slight movement, while a heave is more vigorous movement. It is a sustained foreceful thrusting of the ventricles during systole. You may see a right heave at the sternal border and a left ventricular heave at the apex.

Can you sell a house that has been underpinned?

How can you tell the difference between subsidence and settlement?

Settlement often appears in new buildings and is a common sight as the ground adjusts to support the weight of a new house. Subsidence is the downward movement of the ground beneath a house, where the supporting soil moves away from the building and makes it unstable.
