Welcome to Naylor Denlok
For a company with its origins in clay pipes and over 100 years of experience in the manufacture of clay pipes and fittings, it is natural that Naylor Drainage Limited is in the forefront of product development and innovation.
With worldwide operational activities, Naylor Drainage has become the world's leading international supplier of specialist pipes for trenchless technology and many prestigious projects have been supplied both in the company's domestic (UK) market as well as many continents overseas.
Reputation for product reliability and customer service is part of the Naylor tradition.
The company's trenchless technology product - Denlok® - is a specially developed vitrified clay pipe system to meet the requirements of pipe installation by trenchless construction methods which include:-
- Microtunnelling
- Guided Auger Boring
- Pipe Bursting
- Pipe Eating
- Slip Lining
The Naylor approach to its development of products for the trenchless construction industry has resulted in new manufacturing equipment and production techniques. These progressive steps have led to reductions in specialist product costs and these savings have been passed onto the customer to enable the use of a first-class product at affordable prices.
Clay pipe technology
Denlok® is covered by and fully certified to EN295, the European standard for vitrifed clay pipes and fittings and pipe joints for drains and sewers.
Major advantages of Denlok® Vitrified Clay Jacking Pipes are:
- High-axial strength for jacking force assurance.
- High crushing strength for load bearing capabilities.
- Smooth wall surface with very minimal frictional resistance.
- Accurately machined pipe ends for easy load transference of jacking force.
- EPDM elastomer sealing components and particle board thrust rings factory fitted. Particle board components tested as best material for load transference.
- Wide range of diameters available.
- Worldwide international project-supply references.
- International Technical and Commercial Support.
Trenchless Technology
Until recently, city administrators and planners believed that the use of construction techniques involving surface trenching was the only option for the construction and repair of utility services. It was assumed that existing services were in good condition unless there was evidence to the contrary. In reality, gradual deterioration went unnoticed and failures occurred without warning, in many cases requiring an urgent response.
Over the last 25 years, it became apparent that little was known about existing utility services. Installation drawings, where they existed, gave little information on pipe capacity or materials used. Furthermore, the condition of the pipe linings was unknown, leakage and infiltration were unmeasured and related health issues were often not addressed.
