Hanley Park is one of the UK’s largest Victorian public parks and in 2015 secured £4.5 million of National Lottery funding from The National Lottery Heritage Fund and The National Lottery Community Fund. This money was used to restore the 123-year-old 60-acre site.

The footpaths around the park required resurfacing to allow visitors to safely walk around the 60 acres and visit the popular attractions which include a new pavilion with café, three children’s play areas, fishing, bowling and a multisports pitch.

Henry Williams & Son are National Highways sector scheme 13 accredited for surface treatments, including surface dressing, and worked with multiple other contractors including Horticon and The Casey Group on all phases of the works at Hanley Park.

Working alongside the principal contractor and many other contractors doing the wider park improvements, Henry Williams & Son carried out the footpath and carriageway surface dressing. The specification for the surface dressing was designed by its in house NHSS13 trained contract manager in accordance with the road note 39 guidelines.

Henry Williams & Son’s specialist plant for footway surface dressing operations is designed and constructed in house, based on the company’s vast knowledge and experience in this area. it is bespoke to Henry Williams & Son and produces a calibrated and accurate application of the bitumen emulsion binder and the chippings, to provide a quality assured product.

Accurate calibration and testing of the plant and its rates of spread (ROS) are critical to ensuring quality compliance and the successful delivery of a quality product. Too much application will result in bitumen ‘bleed’ through the surface and too little binder will release the chippings and create ‘bald’ areas and a similarly poor finish.

All of the design work created by Henry Williams & Son is checked against Road Note 39. As the team works, it checks the rates of spread are correct by carrying out carpet tile testing on the binder and tray testing on the chippings.

The carriageway surface dressing works at Hanley Park were laid through a combination sprayer/chipper (Chip Sealer). The Chip Sealer applies both the bitumen and chippings within the same operation and provides the team with a computer-controlled calibration of both materials. This reduces the amount of plant and labour on site and provides a fast, safe and low impact operation.

The works were also carefully phased to ensure members of the public retained safe access around as much of the park as possible at any one time. To achieve this, there were clearly signed diversion routes whilst the footpaths were resurfaced.


The footpaths were all upgraded swiftly and safely with Henry Williams & Son working collaboratively with the principal contractors and other sub-contractors.

The ‘new’ pathways now enable people to move around the park comfortably. This, along with the wider improvements, has encouraged more visitors.

Working on footways is a key part of the service offering from Henry Williams & Son, which has specialist equipment available, able to work on all different types of footways. As such, the business continues to look at how it can innovate in this area. For example, current footway options are via overlay or slurry seal, whereas carriageway options include surface preservation treatments which protect and extend the life of the asphalt infrastructure. Asphalt preservation is an area in which the company aims to lead with new ground-breaking solutions.
