DIRECTIONAL DRILLING HDD
Directional Drilling specialists in the UK
Directional drilling is a method of installing pipes and ducts underground as an alternative to traditional open cut techniques, or in circumstances where these methods are not practical. By utilising directional drilling, it minimises disruption to the public and the environment. Directional drilling can be utilised in various ground conditions ranging from cohesive to rock.
Installations can be carried out under road, rails, rivers or other areas where traditional methods are not suitable. Installation lengths of in excess of 1000m have been achieved and diameters of up to 1000mm have been successfully completed.

What is
Directional Drilling?
The method of directional drilling is capable of 4-way dimensional steer allowing the operator to complete the first stage pilot bore to a pre-determined bore path and allow them to correct and make any changes where necessary. The hole is opened to a size suitable to install the product pipe, this is termed as back reaming and this process can take place in various stages. Once the reaming has been completed the product pipe is pulled back to the machine and the job completed.
Horizontal directional drilling is carried out by jetting and pumping of fluids throughout the whole process, this is aided by adding bentonite, bentonite substitutes and polymers which removes the cuttings while the hole is being reamed. Bentonite and Polymers also add bore stability and lubrication to enable a smooth pulling of the product pipe.
