House Foundation Piling – Park Avenue South, Harpenden

Known for being a reliable piling contractor, Fallon Piling is often contacted by developers and property companies looking to lay the foundations for their new projects. One job in particular took the team to leafy Harpenden, a Hertfordshire town that sits in the affluent district of St. Albans.

The client for this job was Westfield Homes, a developer that works across London and Home Counties – much like the team at Fallon. Westfield had recently acquired a large house in the Harpenden area, and were planning to demolish the existing structure in order to build a detached mansion. With six bedrooms and an indoor swimming pool, this would certainly be a luxurious home for the lucky buyer.

However, before they could get started on any of this, they were going to need some concrete piling. And that was where the team at Fallon & Co came in.

Why Was Concrete Piling Required?

There were a number of reasons that piling proved necessary for this particular job. For one, this particular construction was a brand new dwelling that was going to be built near a lot of large trees. Big tree roots take moisture from the ground, and this can cause risk to more traditional footings. Piling is a much safer solution.

Trees surrounding the ground can make concrete piled foundations a challenge.

The ground also consisted of heavable clay, meaning that in the right conditions – such as a great change in moisture level in either direction – it’s liable to move. This can lead to building subsidence if a dwelling is built on foundations that aren’t made to take this kind of movement. Once again, piling is the best way to make sure the structure is safe.

The Job – Preparing and Installing Foundation Piling

Appreciating the chance to enjoy some sunny autumn days in picturesque Hertfordshire, the Fallon Piling team got to work. The ground conditions were London clay overlaying chalk, and the first thing to do was to flatten and prepare the ground to make it ready for piling.

With this done, it was time for the piling itself. The team opted to use CFA 350mm diameter piles, getting it done with the 18.5-tonne Hutte 205 drilling rig.

Once the piles were in place, the team were able to lay the foundation – a Fallon Piling Rapid Raft Foundation on load-bearing CFA piles. And don’t forget that indoor swimming pool – this also included an in-situ indoor swimming pool substructure.
