Mini Piling: the Ideal Foundation Solution for Wrap-around Extensions
If you plan on building an extension or a new structure on a site with difficult ground conditions, mini-piling is an excellent solution. However, contact expert Mini Piling Contractors in Essex for the desired results. Mini Piling is a popular technique used to create building foundations when traditional methods, such as strip foundations, aren’t possible or cost-effective.
Mini pilings involves drilling small-diameter holes and filling them with concrete, steel, or both. These piles are then used to support the building’s weight and transfer it to the ground. The advantage of mini-piling is that it can be done in confined spaces and on sites with limited access. It’s also less disruptive than other piling techniques, making it ideal for residential areas.
Different materials can be used for mini piling, and each has its advantages and disadvantages.
Steel is a common material used for mini pilings, and it is solid and durable and can be easily driven into the ground. The steel piles can be prefabricated, which makes them easy to transport and install. However, steel piles can corrode over time, affecting their strength and durability.
Concrete is another popular material used for mini piling. It is strong, durable, and resistant to corrosion. Depending on the project requirements, concrete piles can be cast on site or prefabricated. However, concrete piles are heavy and difficult to transport and install.
Timber is a traditional material used for mini pilings, and it is lightweight and easy to handle, making it ideal for smaller projects. The timber piles can also be easily cut to length on site. However, timber piles are susceptible to rot and insect damage, affecting their strength and durability.
Composite materials, such as fiber-reinforced polymer (FRP), are becoming increasingly popular for mini pilings. These materials are strong, lightweight, resistant to corrosion and rot, and easy to transport and install. However, composite materials can be expensive as compare to traditional materials.
Why Mini Piling for Wrap-Around Extensions?
Wrap-around extensions, as the name suggests, wrap around an existing structure. This means that space for foundations is often limited, and the existing structure cannot support the weight of a traditional foundation. Mini piling is an ideal solution for this problem as it is suitable for areas with limited space and can provide strong support for lightweight structures. Mini piling can also be used where there is a need to protect the existing structure, such as in conservation areas, as it can be installed with minimal impact on the existing structure.
Methods of Mini Piling
Different methods of mini pilings can be used for wrap-around extensions. The most common methods include:
Rotary Auger Piling
This method involves drilling a hole into the ground using a hollow-stemmed auger. The auger is filled with concrete, and a reinforcement bar is inserted into the hole. This process is repeated until the required depth is achieved.
CFA (Continuous Flight Auger) piling involves drilling a hole into the ground using a hollow-stemmed auger. Once the hole is drilled, concrete is pumped through the auger’s hollow stem while the auger is withdrawn from the hole. This creates a continuous concrete column in the ground.
Driven piling involves driving a pile into the ground using a hydraulic hammer. This method is suitable for soil conditions too hard for a rotary auger or CFA piling.
Mini piling is a popular solution for wrap-around extensions as it supports lightweight structures in areas with limited space. The different methods of mini-piling offer flexibility to meet different soil conditions and project requirements. It is necessary to consult with a professional piling contractor and Mass Concrete Underpinning Services to determine the best method for your project.
Mini Piling Cost In The UK For Wrap-Around Extension
Mini piling is a popular solution for foundation works in the UK, particularly for wrap-around extensions where access is limited. The cost of mini piling can vary based on factors such as the ground conditions, the size of the project, and the type of equipment used.
For a wrap-around extension project, the cost of mini pilings can range from £100 to £250 per linear meter. This cost includes the materials, labour, and machinery needed for the project. The cost can vary depending on the complexity of the project and the depth of the piles required.
Other factors that can affect mini piling’s cost for a wrap-around extension include the site location, access to the site, and any additional work that may be required, such as excavation or removal of existing foundations.
A detailed quote from a reputable mini-piling contractor is vital for an accurate estimate. Comparing quotes from multiple contractors is also recommended to ensure you are getting the best value for your money. Investing in a reputable and experienced contractor can help ensure the success and safety of your mini-piling project.
