Surface Dressing

The surface dressings used on roads, driveways, footpaths, canal paths, cycleways, carriageways, or car parks are fundamental to durability, road user safety and cost-effectiveness. Options include anti-skid surfaces or reparatory dressings to improve the aesthetic appearance of driving routes or pedestrian passageways.

We custom-blend polymer-modified binders for each surface dressing project to guarantee optimal strength and invulnerability to chipping, surface damage or deterioration during extreme weather conditions or in periods of extensive use.

Surface aggregates range in size from finer-grade blends to substantial 14 mm substrate aggregates, designed to cater to every requirement from decorative residential driveways to robust commercial spaces, public highways, and functional footpaths.

asphalt preservation

Asphalt Preservation 

Our asphalt preservation services are an excellent opportunity to repair and upgrade the performance, strength and life cycle of an asphalt road, carriageway, or entrance route, enhancing organisational sustainability and avoiding excessive costs where asphalt does not need to be replaced entirely.

Intelligent preservation treatments are compatible with any road or footway, ensuring you can maintain roads and through routes to the highest standards while implementing good surface conditions for the years to come.

We use Rhinophalt® preservation treatments, protecting your investment in asphalt surfacing, increasing the usable lifespan of asphalt by as much as 100%, and reducing long-term upkeep and reactive maintenance costs.

Bond Coating and Vertical Joint Sealing

Bond coating and vertical jointing are in high demand to ensure surfacing meets health and safety requirements and evolving legislation. Our surface preparation services include machine-applied polymer-modified bond coatings, applied at precise spread rates for future-proof performance.

We deploy a range of emulsion tankers depending on the size and nature of the surface area, alongside combination spreaders that apply polymer-modified bitumen to vertical surfaces. Our contracting teams can also over-band to seal and safeguard the free edges of carriages with exposed verges.

Surface preparation requires a diligent approach to safety, performance and long-standing road surfaces that outperform conventional hand-laid applications and ensure the finished effect is perfectly even, level, and consistently distributed.

Re-tread is an environmentally sustainable process consistent with departmental and governmental objectives in terms of enhancing the safety and quality of roadways and footpaths without unnecessary expense, material usage or disposal of older surfacing.

The process involves planing and regrading existing aggregates, reprofiling the surfacing material before combining it with emulsion and bitumen, and compacting the application to ensure a level, safe and high-performance surface system.

Henry Williams & Son can advise on the appropriate options, with graded surfacing suitable for HGV traffic, high-volume carriageways, pedestrian footways, and car parks. We can also re-tread surfaces for private yards, depots, and facilities, using innovative recycling processes to meet corporate sustainability targets.
