The prime piling team were excellent - leveraging their expertise to manage the complexities of the site and working round the the poor foundations of the existing building. Great level of service, soup to nuts - fundamental activities (e.g. shuttering) were included and not an added extra as some other people had quoted. highly recommended!

Prime piling have just finished working for us- I had zero experience or knowledge of them or Piling before - They arrived on schedule & explained what was required and just got on with it. Despite finding some inevitable problems in an awkward location, Jamie and his guys swept them aside in a very professional manner. They left the site in good order every night and always consulted with us on best and cost effective option. I will definitely be using them again and we are very comfortable to leave a review and / or recommend to others. A 5 star company......

We used Prime Piling for our extension. We have found them extremely reliable, thorough and professional. They came when they said they would come, finished when they said they would finish and did the work to a high standard which was approved by the building controller.
Prime Piling were great on the job that grew more and more difficult by the day at no fault of their own. Jamie and his team were responsive and kept me up to date throughout the project even offering me help and advice. Would definitely use them again and recommend them to others.

We found Jamie and the team to be very experienced professionals in the groundwork/piling services. It took us some time to find reliable company and we were not disappointed with our choice. Initially, we had a wrong evaluation by the appointed structural engineers and Jaimie managed to find a solution without delaying our project. Very professional, calm, reliable.

Jamie and Kieran were fantastic. Jamie kept us informed during the project and the workmanship was great. I wish I had been in contact with Jamie earlier in the process, as he’s keen to keep the costs down, especially during the design phase with the engineer. I would highly recommend getting in touch with Jamie and Samantha for your piling and job.

After an initial inspection the quotation was agreed. The engineers commenced the work on the due date on time and performed the job in a clean professional and helpful way. I was impressed by their attention to detail and their willingness to adapt if and when needed. I would have absolutely delight in recommending this company for piling work again and if you need a reference you may contact me though them.

Process of SCD Piling

Steel Cased Driven Piling method is as follows:

Drop hammer pilling rig has a cylindrical shape used within the casting.

Once the tube is positioned in the right place, a plug is formed to seal the bottom of the tube.

The ground compacts as the weight goes down the tube and strikes the bottom shoe, driving the case deeper into the ground.

Next, additional tube elements of limited strength are added.

These tubes are driven to the required and appropriate installation depth.

Next, the concrete is cast.

Lastly, the weight is drawn to place a single steel bar within the pile for additional reinforcement.

As the pile is filled with strength, it is left to set.

Steel Case Piles: Fields of Application

SCD piling is used in confined and narrow places, including hard-to-reach areas with restricted headroom.

Ideal for contaminated and aggressive soil conditions.

This type of piling is suitable and appropriate for soils with a strong water flow where the casing protects the newly laid concrete.

Suitable for piling through cavities.

Works great in situations where the cut-off level is higher than the ground level.

Additionally, SCD piling is used in industrial projects, railway works, infrastructures, housing constructions, renovations and hydraulic engineering.

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.

Prime Piling provides different types of piling depending on the condition and requirements of our client:

  • CFA Piling
  • SFA Open Bore Piling
  • Mini Piling
  • SCD Piling
  • Our team takes time to comprehensively understand your needs and requirement for the project.
  • Our team will pay a visit to the construction site and discuss all the important details.
  • Our SCD piling services are of the highest quality along with competitive market rates, thereby always delivering value for money.

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.
