Bored piling

At CLL we lay the foundations for structures to be built upon, and CLL has many ways to bore a hole in the ground. We bring a unique approach to difficult ground conditions, and our methods often result in increased speed and lower costs for clients.

Our capabilities include holes from 200mm to 2.0m wide, up to 50m deep, as well as a number of specialist piling rigs which can handle all technical difficulties.

Design assessment sits alongside CLL’s versatility and extensive knowledge of piling systems, and enables us to advise on optimal cost effective alternatives.

Our fleet of pendulum rigs ranges from 32T to 5T, and we specialise in difficult access piling. In tricky ground conditions we can call on some of our specialised equipment cases and dewaters holes, while other apparatus is used for tremming concrete.

We have a number of vibes for installing and withdrawing casings, and a core range of drilling equipment including:

  • Core barrels
  • Suction balers
  • Clear-out buckets
  • Grooving tools
  • Rock grabs
  • Picks, and
  • Specialist augurs

“Bored piling is very much a generic term. There’re many different systems and techniques for different conditions, and to provide a stable foundation for different types of building. It’s a bit like saying you’re buying a car. You decide whether it is going to be a Toyota, Volkswagen or Mercedes. Then you’ve got to decide on the particular model. Your choice depends on numerous factors, and it is the same with the type of piling foundation to be used. For example, you could have a clay-based soil that’s quite stable and you can put in reinforcing and concrete, and you’re finished. Then you might have a wet soil that’s liable to collapse and you’ve got to use a temporary casing to shore it all up.”

“Every situation is different, every requirement has its own particular foundation requirement. We understand what’s required in the ground and out of the ground. We have the knowledge, experience and expertise to produce the result our client wants.”
