Supertrench – footway was developed and created by our technical team as a reinstatement solution for Lancashire County Council. 



With over 13,000 utilities trenches per local authority dug on our road networks outside of London in 2012*, and significantly more on our footways, ensuring trenches are dug and reinstated with no detrimental effect to pavement quality is a key issues for all local authorities.

Lancashire County Council had an ongoing programme in its area to replace gas pipes lying beneath residential pedestrian footpaths. As part of the programme of works a number of utility trenches were excavated that would require permanant reinstatement to the standards defined in the Specification for the Reinstatement of Openings in Highways.(SROH)   

To ensure a high level of durability and to reduce impact on the local community and subsequent maintenance budgets, a Supertrench Footway was trialed as a  reinstatement solution. 


Supertrench – footway was developed and created by our technical team as a reinstatement solution to meet exactly this need.  

Supertrench- footway is a permanent hot mix asphalt surface course for use in the reinstatement of flexible footways, footpaths and cycle tracks. It’s both highly durable and easily compactable and compatible with the flexible footway reinstatement requirements Method A of SROH. This volumetrically designed binder rich surface course also reduces issues of compactability and therefore reduces the risk of failure to meet the air void specification required by the SROH.

Supertrench-footway supplied from our local plant at Darwen was installed into each trench reinstatement in two layers, each to a depth of 30mm. 6mm coated chippings were then evenly hand spread on the top of each reinstatement to provide a finish matching the existing surface and to provide slip resistance to pedestrians.
