What you need to know about Basement Underpinning

by | Jun 19, 2023

For most people, the idea of increasing their property’s size tends to centre around luxurious extensions, annexes and conservatories. For those with acres of space and sufficient investment, this may indeed be possible. When it comes to living in urban locations, however, additional land comes at a premium. Hence affordable alternatives often need be considered. So, if you’re unable to expand outwards, then why not consider building downwards through basement underpinning?

Underpinning involves the excavation of a basement beneath a property, and at Borehole Solutions, this is something we’re well-versed in. Today, the team wanted to take a deeper look (pun intended) into what this excavatory process requires.

Why should I consider Basement Underpinning for My Property?

There are many reasons why someone may decide to install a basement. For some, they view it as an effective method of adding value to your property. For others, however, it’s often simply the case of wanting more space within your home. Whether your basement is used for extra storage or your dream indoor swimming pool – the opportunities are endless. Regardless of your intentions, it’s not difficult to see the benefits in which basement underpinning can provide for your home.

What is the Underpinning Process?

Underpinning is a means of lowering the existing foundations of a building to create space for the basement’s installation. Whilst there are many approaches to this, the main method employed within the industry is typically the mass concrete pour. With this technique, holes are dug below existing foundations, and either regular or reinforced concrete is poured into them. Some alternative processes that are also utilised include the beam method, as well as piling for more heavy-duty projects.

Do I need to consider Planning Permission?

In most circumstances, yes, your basement underpinning project does need to obtain approval under building regulations. This is especially true if your property is located within conservation areas or is deemed to be a listed building. Receiving this approval is, unfortunately, not a straightforward or short process. There are a number ofstages involved, including digging a trial pit to assess ground conditions beneath your home. For more information on this, click here!

The Party Wall Act of 1996

Unless your property is standalone, you also need to consider the implications of the Party Wall Act. This outlines the dispute-resolution process between neighbouring properties where work carried out by one owner could impact the other. Considering that most underpinning projects take place on properties where walls are shared, this must almost always be considered. It’s important to note that before any underpinning project commences, consent from your neighbour must be obtained.
