Product: DN225 Naylor Denlok NC Jacking Pipes
Client: Redrow
Contractor: Allen Watson Limited
Allen Watson Ltd who provide trenchless installation
services to groundwork contractors and building rms
across the UK, were the contractors for the recent foul
sewer installation project at a Redrow Housing
Development in Kent.
! Pipe bursting
The project challenge was to install a 225mm no dig
drainage foul sewer system under Sutton Road in
Maidstone, Kent.
Denlok Express rises to the
challenge
Naylor Denlok is a specially developed vitried clay pipe
system, available ex stock, to meet the requirements of
pipe installation by trenchless construction methods, such
as:
! Microtunnelling
! Guided auger boring
The solution was achieved by using Naylor’s DN225
Denlok clay jacking pipe, installed using an AWL GAB.85v
guided auger bore machine with optical electronic
navigation.
! Pipe eating
! Slip lining
Simon Marsh, the project manager at Allen Watson,
commented “There was extremely limited site space at the
project and AWL were supported by the Naylor Drainage
new lead time protocol of direct to site delivery within 5
working days. This facilitated the delivery of pipes for each
individual drive, keeping the site footprint to a minimum”
