Frequently Asked Questions
Piling is the process of inserting structural piles into the ground that will become the base of the building. Piles are required where soil and earth are performing poorly and are used to spread the load of a building and firm the ground. They are a cost-effective approach to combating corrosion and are proven to significantly improve the life expectancy of a structure
The size of the trench depends on the size of the ground beam to be installed. For our typical ground beams to an extension an excavation of 600mm deep and 450mm wide is sufficient. Please ring for advice.
There are a number of reasons it may be: A site investigation has highlighted that the ground is unsuitable and un-useable to a depth of more than 2 metres. Removal costs for the excavation of traditional deep trench foundations are too expensive. Foundation trenches are not stable and health and safety, therefore, becomes an issue. There is a high-water table. Where there are soils such as clay that are likely to swell or shrink excessively depending on the amount of water content.
The job of the pile is to distribute the weight of the structure evenly. They are placed into the ground using a pile driver. Holding the piles perfectly vertical, this machine hammers each structure into the ground and also acts as a crane.
For a typical house extension, the work can take around 2-3 days, depending on the depth driven and services requested. For more complex projects, contact us for a more specific time frame.
Mini piling in Essex and Colchester is a type of specialist piling that incorporates a specific arrangement and number of driven pile and screw pile varieties. It allows for the expansion or extension of a building, while also safeguarding against ground heave and subsidence. Crucially, mini piling is often a cheaper, faster option than traditional deep trench foundations.
