FAQs

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 can I find a builder in my area?

Finding a builder nearby can have enormous assistance when it comes to your build. Period on site, their familiarity of local planning permission, constructors’ dealers and other local trades are all vital bits of knowledge that you’ll welcome on site.

It is always wise to walk around in your local area or drive to a site where any construction work is going on. It’ll give you a proper impression of the constructors who are active nearby. You don’t have to like their style of work or the project they are currently carrying out – after all, a builder can only produce what’s on the plans in front of them.

Find a Builder Other Tradesmen Recommend

If you’ve had to call an electrician before or a local plumber and liked their work, you can always ask them if they have any builders whom they would recommend. 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.

Always Talk to Previous Customers

Once you’ve found a builder you would like to work with, ask them for a list of previous customers they have worked with; they ought to be glad to offer particulars if they’re self-assured they’ve done an effective job.

Look for a builder online

A decent place to start looking for builders online is on sites like the ours so that you can find quality tradespeople and see genuine reviews from previous customers. Not all online review sites can be trusted to display real reviews.

Can builders work on a Sunday?

General construction work should be restricted to the following hours: Monday to Friday 8am to 6pm. Saturdays 8am to 1pm. Most councils advice that noisy work is prohibited on Sundays and bank holidays but you should check with your local council to confirm this.

how to underpin a house

The importance of underpinning a house cannot be overemphasized. Firstly, what is underpinning? Well, underpinning is simply the act of reinforcing, repairing, strengthening or improving the depth of an existing foundation by lowering the footing to ensure that it rests more on more reliable and supportive soil. Not only does this method help to strengthen your building and preserve its structural integrity, but it also does increase your property’s value and gives you peace of mind knowing your property is safe. If you’re thinking about underpinning your house, you have two options – do it yourself or call in a reputable structural engineer. The latter is more advisable as the method involves a lot of specialized knowledge, skills and tools to guarantee a successful outcome. In this post, we’re going to take you through the process involved in underpinning a house. Let’s take a look!

To get started, you should know that concrete underpinning features excavating pier footings around the building at about 2 to 3 metres distance between each other. In some cases, underpins can be installed from within the house. The footings of the underpin should go very deep into the underlying soil in such a way that fully supports the weight of the building or structure. Once done, now proceed to attaching the new footing to the building. You can achieve this by excavating underneath the existing footing to make for a stronger prop. Individual prop and pier arrangement is then strengthened using strong steel bars. Once completed, the concrete is then poured.

A professional underpinning contractor will make sure there’s sufficient space left between the existing footings and the new underpins as this space will ensure that the new underpins can be easily used to jack up the house and level it once the poured concrete cures.
