Our Services

Here is a list of the services we offer, whether it's something as little as labour work to something as big as full site investigation drilling. We have the equipment and expertise to cover a wide range of services within the drilling industry. 

  • Cable Percussive Drilling

    This is the most common drilling method used for geotechnical site or ground investigations. Since the beginning of Gary Wheeler Drilling Ltd, we have predominately specialised in cable percussive drilling.

    Cable Percussion drilling uses a mobile rig, driven by a diesel engine and a tripod derrick of about 7m height. The derrick folds down so that the rig can be towed by a four-wheel drive vehicle.

  • Windowless Liner Sampling

    Windowless sampling involves the use of a small tracked drilling rig that has a drop hammer to drive in sampling tubes. Depth is achieved by successively driving tubes into the ground, via extension rods from the base of the hole made by the preceding tube.

    Samples are recovered in plastic liners which are slotted into the sampling tube and retained with a threaded collar. The plastic liners provide a continuous core samples which are returned to our laboratory for detailed logging.

  • Well Drilling

    We can provide you with pure water from your own water well. In the past if you wanted to drill a water well you had to apply to the National Rivers Authority for a Licence. In the last few years they were absorbed into the Environment Agency. 

    In 2003 a change in UK law means that anyone can have a private water well supply, and can pump up to 20,000 litres per day without requiring a licence. There are no restrictions on the use to which the water can be put. We use our Cable Percussive rigs for this area of drilling.

  • Dynamic Probing

    This type of testing involves the use of the same small tracked drilling rig used for windowless sampling. Dynamic Probing involves the driving of a metal cone into the ground via a series of steel rods. These rods are driven from the surface by a hammer system that lifts and drops a 64kg hammer onto the top of the rods through a set fall, thus ensuring a consistent energy input.

    The number of hammer blows that are required to drive the cone down by each 100mm increment are recorded. These blow counts then provide a comparative assessment from which ground engineering properties may be derived.

  • Foundation Pits

    Foundations pits take place when someone would like to find the footings of a building. its performed in the same way as hand dug pitting but for a different objective.

  • Hand Dug Pitting

    Hand dug trial pits are normally performed, depending on soil conditions, to a depth of 1.2m. This method is used as a safe way to check and clear a position of any possible underground services.
  • Concrete Coring

    Concrete coring is a method of removing hard standing such as reinforced concrete. It uses a large diamond tipped core barrel to drill through the hard top for easy and clean removal. This normally takes place prior to drilling investigation which takes place on hard standing.

  • Vacuum Excavation

    A trailer mounted extraction unit for a safe way of excavating trial pits and trenches in high service risk areas without the use of sharp tools that could strike or damage services. With a high power jetting lance to agitate the soil which is then sucked up into a tank on the trailer it is the safest and cleanest method of digging.
  • Gas / Water Monitoring Wells

    A monitoring well is best described as a Borehole (BH) Installation, installed to obtain samples or monitor gas⁄water levels within the ground.

    All rigs are equipped to drill Gas⁄Water monitoring wells. These well can be drilled to provide single or multi-level monitoring⁄sampling point at a site location. The wells can be drilled using a wide range of drilling method depending on required depth, diameter, ground conditions and site specific requirements.
