Mole strives to reduce the negative impact of infrastructure changes through focusing our innovation and efficiency. Our trenchless methods allows our business to consistently deliver environmental benefits. We proudly hold an accreditation with the Environment Agency. We have won numerous ‘Green’ and Environmental Awards for our work in this industry and our energy efficiency projects including our innovative Combisave product. We actively look for ways to reduce the environmental impact of our work, and our drilling rigs are amongst the “cleanest” in the country because they do not rely on bentonite as a lubricant.
We value our staff very highly at Mole and invest in training, providing opportunities for skills and professional development through courses, apprenticeships and NVQ Schemes. Professional development, health and safety training and plant operations training are all programmes delivered to our staff in conjunction with external training suppliers and awarding bodies.
We hold accreditations to CHAS, Constructionline and Acclaim, and are proud to be associated with the following industry training and competence schemes:

About Mole’s Drilling Rigs
At Mole Engineering we have 5 HDD rigs in total:
Our 14 tonne drill rig provides thrust/pullback force with the capability of 3,800 ft-lbs of rotary torque, with a maximum rotary speed of 225 rpm. Weighing in at 20,000 lbs (247″ by 89″) and a working footprint of 10 metres, this drill is able to handle the toughest of jobs. Powered by a 125-horsepower John Deere turbocharged diesel engine with an onboard FMC mud pump capable of pumping 47 gallons per minute at up to 1500 psi. The rig uses a 10-foot drill stem that can carry up to 500ft of up to 350mm duct. This is an incredibly versatile drill rig and is perfect for network links, roads and many more.
Our compact and very manoeuvrable 4X Drill Rig is particularly useful in confined spaces and poorly accessible terrains, thanks to its small footprint and limited weight.
Our 6 tonne surface launch rig has around a 5 meter footprint making it very compact – the distance from the back of the rig to where the drill head enters the ground is about 5 meters. This rig has the capability to drill up to 120 meters.
Our 6 tonne pit launch rig is 1.8 m long and requires a pit of around 4 square metres to be dug before launch. This rig is ideal for railway crossings, road crossings or similar, where you have not always got enough distance before the obstacle to reach the required depth using a surface launch rig. This rig is also ideal for drains, as our specialist engineers can drill from the site complex out into the road and directly down into the main manhole chamber, pulling in a new pipe without any excavations at all in the road. The pit launch rig is accurate to a fall of 1:100.
Our 1.1m, 3 tonne rig must be one of the smallest rigs in the country. It is a small rig with 1/3 meter rods but has the capability of drilling in up to 6 inch pipe for up to 20 meters – ideal for road crossings, drilling under houses or drain connections. We often use this specialist directional drilling rig in place of a mole (for example when using a 63mm or 75mm mole to put 63mm piping or 2 1/2 inch ducting across a road). We prefer to use this compact drilling rig because it has total capability steering and tracking, so we know exactly where we are going! It may take a little bit longer to set up but the risks are lower, the job is quicker and the customer is happier!
