Welcome to The Demenex Group of Companies.

Dedicated to a Quality Service!

Demenex Group are a family owned business which has been-established in London for almost 25 years. We specialise in Civil Engineering, Demolition and Heavy Equipment Plant Hire, Sales and Services from our depot in Bow, East London.

In 1999,  Demenex Plant (Ireland) Ltd was formed and we opened our first depot in Newry, Northern Ireland. In 2001, we opened a second depot in Belfast, with our third depot opening in Dublin in November 2003. The strategic location of these depots means that we have access to the whole eastern region from Coleraine to Waterford.

We offer plant for hire and also sell high quality second hand equipment. It is our company policy that all plant for hire is under 3 years old. All our operators are CSR/ CITB / CPCS trained, ensuring you get a professional service.

Demenex also offer demolition /  groundwork services and CITB training for construction operatives from our new construction training centres in London and Newry, Northern Ireland.

We operate an aggregates and materials business from our London depot to provide aggregates and concrete crushing facilities within London and the Home Counties.

Demenex are dedicated to providing a quality service at a realistic price, and by identifying and understanding our customers requirements, Demenex aims not only to fulfil their requirements, but to surpass them.

We operate 24 hours a day - 7 days a week from each depot. All operated plant / lorries are in continuous mobile communication with the relevant area office and all vehicles possess satellite tracking devices, thus allowing current location to be confirmed.
