Allen Watson Ltd (AWL), a company providing trenchless installation services to groundwork contractors and building firms across the UK, was the contractor for the recent foul sewer installation project at a Redrow Housing Development in Kent, UK.
The project required the construction of a 225 mm diameter, trenchless installation for a drainage/foul sewer system under Sutton Road in Maidstone.
The project was achieved by using DN225 Denlok clay jacking pipe provided by Naylor Drainage Ltd, installed using an AWL GAB.85v guided auger bore machine with optical electronic navigation.
Naylor Denlok is a specially developed vitrified clay pipe system, available ex-stock, to meet the requirements of pipe installation by trenchless construction methods, such as:
• Guided auger boring
• Pipe bursting
• Pipe eating
• Slip lining
Simon Marsh, the project manager at Allen Watson, commented “There was extremely limited site space on the project and AWL was 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.”
