Piling and Underpinning Services in KwaZulu-Natal

Underpinning is the careful and well-thought-out process of providing extra strength to an existing foundation structure, to either prevent damage from happening or halting the damage that is already taking place and harming the structural integrity of the building.

The process is considered a major repair project and one that should not be left to inexperienced companies. One small mistake can lead to a costly, not to mention dangerous, situation that will set you back. The use of the correct method, along with precise planning, is a necessity.

Problems with your foundations can have far-reaching consequences. Rather than ignoring the tell-tale wall cracks that point to foundation issues, it is best to find a solution to the issue.

When would underpinning be considered a necessity?

There are a great many factors that would point to underpinning being something that you should be having a look into. And should you have any uncertainties about whether you need this service, you can always get in touch with the team at Pinnacle Structural Repairs. Some of the examples of underpinning being needed include:

  • Soil conditions changing beneath the foundation, causing instability. This is why we work with geotechnical engineers who can establish soil conditions.
  • The individual soil characteristics were not correctly taken into consideration during the initial construction phase, leading to instability and possibly wall cracks.
  • Instances where the original foundation is either no longer suitable for holding the structure up safely, or where the original foundation is no longer strong enough.
  • Work being done on neighbouring structures can also lead to issues with foundations. Work can include repairs, excavations or construction.
  • When additional floors need to be constructed underground.

Just as there is a range of reasons why you might require underpinning, there are also several different types of underpinning to be looked at. Pinnacle Structural Repairs will advise you as to which type of structural underpinning will work best for your particular situation and then give you a rundown on what will need to be done to get your foundation back into a safer condition.

Some of the more commonly used types of underpinning for foundations include piled underpinning which is often used when the soil beneath a structure becomes unstable and thus unsuitable for bearing heavy loads. This is not the only reason for using piling. This option is also fantastic for when there is not a lot of access to a construction site or when there are various environmental concerns which relate to soil extraction or the need for limited structural movement during the process of stabilising the foundation.

The options of mass concrete underpinning, geopolymer solutions and jet grouting are also used by various companies operating in this industry.

Wall Crack Repair

One of the most commonly seen occurrences with a displaced foundation (or a sinking foundation), is structural damage, and more specifically cracked walls. Pinnacle Structural Repairs goes beyond the underpinning of all kinds of foundations and also offers wall crack repair as a part of our exceptional services.
