Why Underpinning with Steel Screw Piles and Support Brackets Is Quickly Gaining Popularity in the Construction World


Underpinning is a method used to stabilise faulty building foundations. This sort of building repair may be required because of a number of different reasons, including when the initial foundation is no longer robust or stable enough, when the soil moves and destabilises the foundation of a building, when the properties of the soil on which the structure sits on has changed and when the way the building is used has changed. Regardless of the reason why you may need underpinning services, it is important to know that there are different ways to get the job done. 

One of the relatively newer ways of underpinning a building is through the use of steel screw piles and support brackets. This method of underpinning is typically preferred where the use of traditional pilings may not be feasible. 

Read on below to learn about the benefits associated with this method of underpinning. 

  1. Faster installation speed: One of the biggest perks of underpinning a building with steel screw piles and support brackets is that it saves time and labour costs. There's no need to do major excavations around the foundation of the structure like with most traditional piling. A two-man crew armed with an iron bar can install the screw piles and brackets manually. On sites where the soils are harder, installers can use small machinery like a mini excavator fitted with a hydraulic rotary actuator. So long as the right work tools and equipment are used, steel screw piles and support brackets can be installed much faster than traditional piles. 
  2. Reduced environmental impact: Another major advantage of using steel screw piles and support brackets over conventional piling to strengthen or stabilise faulty building foundations is that it reduces the environmental impact of making soil cuttings. For the most part, underpinning with screw piles and brackets does not involve major excavations. This helps to avoid making a big mess at the work site, but also to minimise noise and vibration that may cause significant damage to the surrounding areas. This, in turn, reduces the need to perform major clean-ups, but also minimises the need for site remediation.
  3. No frost insulation: Unlike most traditional piling, which require frost insulation when used in frost-susceptible soils, steel screw piles and support brackets maintain their bearing capacity even in such soils.

Thanks to these attributes and many more, the use of steel screw piles and support brackets for building underpinning purposes is gaining more popularity by the day. For more information, you should consult a building service, such as Jeffrey Hills and Associates
