Are you considering a house extension? One of the most crucial steps is the excavation process for the footings. As a homeowner in Chichester, grasping the importance of solid footings is vital. A well-executed foundation ensures that your new extension is stable and durable. In this blog post, I will share valuable insights on the excavation process specifically tailored for domestic house extensions, showcasing how my expertise makes a difference & avoid costly mistakes.
The Importance of Proper Footings In Chichester
Footings are the structural bases of any extension, supporting the weight of the building and transferring loads to the ground. If footings are not excavated and laid properly, costly issues can arise, such as subsidence or structural instability & cracking.
By emphasizing proper excavation techniques, I ensure that the footings rest on solid ground, providing the safety and integrity your extension requires. This process involves more than just digging; it’s a calculated procedure that demands planning, knowledge of soil types, and compliance with the local building regulations / Inspection.
Understanding the Excavation Process In Chichester West Sussex, Footings For Extensions & New Builds
Excavating footings for house extensions involves several key steps:
Site Assessment: I begin with a detailed assessment of the site to identify potential challenges, such as drainage issues or existing structures that may affect the excavation.
We offer demolition if required.
Planning and Permissions: It's critical to ensure the project meets local building regulations. This often requires securing necessary permits from the Chichester District Council. For example, failing to obtain these permits can lead to project delays or fines averaging £1,000.
Marking Out: Once permissions are in place, we carefully mark the layout of the footings, ensuring that everything aligns with the architectural plans.
Excavation: The actual digging is done using appropriate heavy machinery & manual tools, depending on site accessibility. I always guarantee that the footing dimensions match the soil type and weight of the extension. For instance, if a new two-storey extension is planned, greater depth may be needed. This will be checked & signed off by the local building Inspector before concrete can be poured, sometimes creating a few delays!.
Base Preparation: After excavation, we meticulously level the base and ensure proper drainage is established to prevent future issues, if required.
Rendering and Reinforcement: sometimes incorporate steel reinforcement bars, especially for larger extensions, to enhance the foundation's stability, depending on the specification / structural engineer calculations.
Pouring Concrete: Finally, I pour quality concrete into the excavated footings, allowing it proper time to cure. This process ensures that the foundation is capable of supporting the structure long-term. The type of concrete will be ordered specifically for your project.
Excavating footings may look straightforward, but it requires precise attention to detail to meet all specifications and standards of the local building control.
Soil Considerations
In Chichester, soil types can vary significantly, making it essential to understand the ground beneath before excavation. For example, clay, which is common in this area, can swell and contract with moisture levels, requiring deeper and more robust footings than sandy soils, which can be quicker to excavate.
I always recommend conducting a soil survey prior to any excavation?. For instance, a recent project I undertook revealed clay soil at a depth of just 1.5 meters, necessitating a foundation depth of 2 meters for stability. Understanding these soil properties can be the difference between a safe structure and future issues.
Dealing With Drainage
If required, a proper drainage system during excavation is critical. Without it, water can pool around your foundation, leading to dampness or even erosion over time & making it very difficult to excavate. We can also offer the Installation of your drainage system, new Inspection chambers & soak-away.
Health and Safety Measures
Excavation work involves heavy machinery and can create potentially hazardous conditions. Prioritizing health and safety measures is my topmost concern.
This includes using necessary protective equipment, securing the site, and ensuring that everyone present is well-informed about risks. By following industry-standard safety practices, I ensure that the excavation process remains effective and safe for everyone involved.
Enlisting Professional Help
When it comes to excavation for extension footings, hiring skilled professionals can greatly influence both the process and the final results. With years of experience in Chichester, we offer a comprehensive service that encompasses every aspect of excavation.
While DIY may appear cost-effective, the potential risks involved with foundation work are high. My expertise helps avoid common pitfalls and guarantees that the groundwork of your project is solid. For example, improper excavation can lead to a 40% increase in repair costs down the line & could be very costly!.
Project Timeline
Understanding the timeline for your excavation and extension project is essential for planning.
Typically, the excavation process for footings can take anywhere from a few days to a week, depending on the size and complexity of the extension. After completing the groundwork, additional time for inspections and approvals may be needed before construction advances. On average, about a week is necessary for inspections to ensure everything conforms to local building standards & sinning off is complete.
Top Joints Construction will arrange & pour the correct concrete specified to the correct levels agreed ready for building on.
I maintain open communication with my clients about timelines, keeping them informed throughout the entire process. This ensures clear expectations and promotes effective project management. We deal with all the spoil being removed from site, leaving the site clean & tidy ready for bricklayers.
