Brewis Engineering specialises in the design, development and manufacture of equipment for the Trenchless Technology Industry.  Since 1984 we have been solving trenchless technology problems using innovative design and manufacturing knowledge.

Brewis FactoryWe are a BS EN ISO 9001:2000 registered company operating from modern 10,000 sq.ft. premises in Frome, Somerset, about 10 miles from Bath and Bristol.

Our machine shop is well equipped with modern CNC machine tools and complementary manual machines for low volume and prototype work.  We also have extensive test facilities.

You may not have heard our name but you will recognize some of the products that we have designed and made.

Our founder and designer, Rod Brewis, invented the expanding towing head (or duct puller) that is in daily use around the World.  We make a large range of towing heads and pressure test ends from 25mm diameter to 900mm diameter.

Our two ranges of heavy duty directional drilling pullback swivels start at 10 tons and go up to 550 tons pullback capacity. They are made from high tensile steel and we always use top class roller bearings.  Other features include a one piece shaft for high strength, external power greasing point and a highly effective patented sealing system.

We  manufacture high flow sonde housings and boring heads in a range of diameters and materials.  All our designs use annular flow around a central capsule.  This ensures very high flow rates and gives the added benefit of both insulating and cooling the sonde.

We also work very closely with many OEMs, designing and manufacturing equipment to their specific requirements.

Please contact us if you have a bespoke design requirement, a problem in the field or a manufacturing need.  We may be able to help.

Company Ethos
Based in the West Country we are constantly reminded of the brilliant vision and engineering skill of Isambard Kingdom Brunel.  We may never come close to his achievements but we do strive to design and manufacture equipment with the highest design integrity.

Above all we like "to sleep soundly in our beds at night",  secure in the knowledge that Brewis equipment is fit for purpose.   If you have problems with our equipment please let us know so we may improve it for the benefit of all.
