Maximum tradesmen get used to seeing the similar acquainted names from one place to another in the sites they are working on and every so often has favourites for who they like to work with — and who they see as a good source of work.

when is underpinning required

If you’re currently experiencing some structural issues with your building or property and you’ve heard a thing or two about the several benefits associated with getting underpinning done, you may be wondering if underpinning might just be the answer to your worries. Well, one thing you should when it comes to underpinning is the fact that, while there are some structural issues that may actually warrant an underpinning job, there are also some situations that can not be fixed by underpinning. In this post, we’re going to consider the events whereby underpinning of your house will be required. Let’s take a look!

First and foremost, you should know that underpinning isn’t required for issues related to slab heave. Footing movements which are likely to reverse normally occur when the content of the soil moisture changes unevenly which gives rise to slab heave. This movement results for a reversible effect.

Generally, underpinning is done to remedy problems related with the movement of the footings of a building or property, but as stated above – not all movements require underpinning. So, when is underpinning required? More often than not, a situation that’s resolved by underpinning is the event whereby the footings of a building or structure drops or subside as a result of some reasons that are irreversible. For example, footing movements caused by a footing set on a soft or loose soil which may be irreversible.

In the event whereby the footings of your house haven’t been installed as deep as required during the initial construction, then you will need to have your building underpinned to make it more stable. If you’re also looking to increase the load on your foundation like adding another storey, you may also need to have your house underpinned to support the extra weight added.

how long does underpinning last

Have you been advised by a structural engineer or a surveyor that your building needs to be underpinned? Well, this might just have you wondering what underpinning really is and how long it lasts. In this post, we’re going to tell you more about underpinning to help you make the best-informed decision possible moving forward. Let’s take a look!

Basically, underpinning refers to the incorporation of one of various methods to reinforce or repair the old foundations of a building or structure mostly to remedy or avoid subsidence. Now, subsidence can be caused as a result of poor soil quality, increase in the load on the foundation like adding a new storey, excavations below the building as well as inadequate foundation which is more common in older buildings. When an underpinning remedial work is carried out, there are a plethora of benefits that comes with it. It’s preserves the structural integrity of your building by strengthening it, make it a lot more attractive, increases the property’s value and makes it a lot safer for both you and your loved ones. So how long does underpinning last?

Well, many underpinning contractors will offer you a 10-year guarantee of its underpinning solutions for defects. Primarily, there are two reasons why underpinning can fail which is poor installation and fresh issues arising or unforeseen circumstances. While the first is an issue that can be avoided by employing the services of an expert contractor who possesses vast experience and knowledge in the field, the second can not be avoided. However, in the absence of the unforeseen issues, underpinning is expected to last for the natural life of the building, so far it has been expertly installed.
