Underpinning in simple language creates support below the ground for an already existing structure at its top. It extends the foundations of the structure down to a depth where they can provide the correct support outside the influence of low-bearing capacity soils. The load is transferred to a suitable bearing stratum and it is required when the structure is sinking or showing signs of subsidence.
It provides strength and support to the structure so that it does not collapse and while the construction technique is improvised, the soil below is excavated and replaced with stronger materials like concrete.
We are a group of specialized and authentic contractors who offer a full range of house underpinning systems. By providing effective and economical solutions to people for remedial or new foundation system we are one of the best underpinning companies. Our highly trained engineers provide the most feasible solution to your problems and ensure that it will be appropriate for the circumstances that are present.
We utilize a wide range of techniques and equipment that enable us to construct a suitable foundation for your building project. We are continuously evolving in both technology and manpower to ensure that our service does well by all our clients.
There are many reasons for underpinning to get done, however, the most important one is when the soil beneath the foundation of the structure starts to move away from it which eventually creates a space between the building and the land beneath it. Due to space, the building is likely to subside into this cavity. Often, this can happen due to the weight of the building itself.
Subsidence can occur due to many reasons like,
Some of the other reasons why underpinning is required include, that maybe the original foundation was just not strong enough, or the usage of the structure has changed over time. The properties of soil might have changed and can also affect the underpinning needs. One other reason could be that maybe a construction nearby is causing the soil to excavate to the nearby side causing support problems in the existing foundations.
There are some clear indications which help you evaluate as to when you need underpinning, some of them are,
When it comes to underpinning, there are several methods available to complete the process. Some of the major ones are,
It is one of the most traditional methods of underpinning and it involves digging of the land beneath the existing foundation to reach a stable stratum deep below the existing one. This is a low-cost method and is suitable mostly for shallow foundations.
This is an upgrade to the mass concrete method and involves insertions of a reinforced concrete beam below the existing foundation. Instead of concrete, this method uses steel bars for stronger support. This is also suitable for deeper foundations and is found suitable for most of the ground conditions.
It starts with digging a hole in the ground through the existing wall of the foundation so that a horizontal beam of concrete mass can be accommodated so as to distribute the load. Piles are then used at either end of the hole or the foundation to support the structure. This method is used when a person wants to shift the current load of the foundation to another stable reinforced platform.
It is used when the foundation needs to be extended only on one side and the structure already has a stronger interior column. It is faster than the traditional methods and has a high load-carrying capacity.
Underpinning is a major advantage for the structures that are being built or have been built earlier as it provides a boost to the stability and strength of the foundation. Some of the advantages of getting it done are,
The most basic reason is that it improvises the foundation of the structure which might have been destroyed due to many reasons. It ensures that the foundation is prevented from all sorts of calamities.
A property with finished underpinning will have more value in the market and it makes it look more desirable to the buyers. So it is financially wise to get your house underpinned if you wish to sell it anytime in the future.
Falling homes can cause vertical height space issues in the building and underpinnings to prevent that. It allows you to have better light fixtures.
There is no fixed time for the process to come to completion. It all depends on the number of underpins which have been specified by the engineers at work.
It has been observed that approximately two weeks are required to put ten underpins. So, according to this calculation, approximately a month is required for the underpinning of a complete house.
This cannot be told unless the complete information about the soil structure is known. Not all types of underpinnings are suitable for all kinds of foundations. It also depends upon the underpinning services used.
We take all types of projects and provide ideal solutions which are suitable for all types of buildings from large to small scale. We ensure that the solutions are cost-effective that suit your specific requirements.
Our highly trained staff is given vocational health and safety training to ensure that any damages to your building are prevented. They also ensure that the contractors and the customers are on the same page regarding any decisions for the property.
We strive to maintain our reputation in the industry and at the same time for customer satisfaction and hope to get good recommendations from them. With a wide range of modern equipment, we are completing all the projects with sincerity and dedication and leading the underpinning industry.
