The Port Talbot Distributor Road is part of a regeneration plan for the Port Talbot area designed to open up land for attracting business and leisure facilities. The new road known as ‘Harbour Way’ is a dual carriageway running between junctions 38 and 41 of the M4. The existing A48 Port Talbot bypass ran through urban areas causing noise, pollution, poor safety and journey times for local residents. This highly prestigious contract was funded by the Welsh Assembly Government who had given a challenge for innovative whilst working within tight programme and budget requirements.
The new road has a mixture of structures including underpasses and bridges including the busy Swansea to London Paddington railway line with limited possession periods. Speed of installation was a key consideration as much of the work was carried out under complex traffic management. Structural drainage was needed for all the earth retaining structures. Traditional methods, such as porous blocks or no fines concrete require manual handling equipment which results in slow installation and potential damage to bituminous waterproofing layers. Access to structures was limited posing potential issues with site deliveries and installation on this congested site.
The contractor Costain investigated more modern innovative and financially beneficial drainage systems such as the ABG Deckdrain geocomposite drainage system as a replacement for the concrete blocks in the original design. The BBA approved Deckdrain drainage geocomposite offers considerable financial and handling
benefits complemented by superior flow capacity and
high compressive strength. The lightweight rolls come in
standard off-the-shelf sizes of 1.1 x 50m or 2.2 x 25m and
are laid horizontally in progressive lifts along with the
waterproofing and backfill. The composite has a filter to
prevent clogging and a high flow core providing
additional impermeable protective layer.
Deckdrain, approved by Neath Port Talbot Council, Welsh Assembly Government and Network Rail, assisted in the completion of the scheme within budget and on time.
Costain received national recognition for this project with the award of ‘Considerate Constructors’ 2013 and ‘Constructing Excellence in Wales’ 2012.
