Pavement Overbanding

Overbanding is a vital process for sealing cracks in roads or surfaces caused by wear and tear, or for sealing joints between old and new surfaces following repairs or resurfacing. It is essential for:

Preventing Further Damage: overbanding protects surfaces from water, dirt, or spillages, preventing surface fretting and degradation.
Sealing Cracks Effectively: the overbanding process seals the crack by overlapping both sides of the joint up to 200mm, ensuring no harmful substances penetrate the crack.

Our Overbanding Methods

We offer two methods of overbanding, each tailored to project needs. The method chosen depends on the project requirements, including the materials on either side of the crack and the intended use of the surface:

Hot Applied Material: ideal for sealing and overbanding cracks on roads, highways, and other asphalt or concrete surfaces.
Cold Applied Resins: typically used for specific applications such as car parks, airport fuelling areas, or locations requiring fuel-resistant properties.

Commitment to Quality & Safety

Both overbanding methods are HAPAS approved, ensuring compliance with industry standards for quality and safety. We prioritise high skid resistance in our overbanding solutions, reducing the risk of slipping or skidding, especially in wet conditions. This is crucial maintaining a safe environment.

Richmond Road, Kingston Upon Thames

Richmond Road, Kingston Upon Thames

Construction value: Circa £10.5k

Client: Royal Borough of Kingston Upon Thames

Key dates: February 2012

Background/Overview

The A307 Richmond Road is situated right in the heart of Kingston upon Thames and is an extremely busy road being the main link between Richmond and Kingston.

Reflective cracking was evident throughout this section of carriageway, with the surface course in need of treatment before potholes began to appear. Kingston upon Thames were looking for a fast and effective treatment that would hold together their carriageway. Further funding was available to resurface this section of carriageway but works had to be delayed due to major statutory works. There was significant risk that another winter would cause the carriageway to structurally fail, and a solution was required.

Project Overview

Taylor Woodrow trading as ESM proposed a fill and overbanding treatment which was applied to the surface cracks using Ultra-Band at a width of 100mm.

Ultra-Band is a pre-mixed, hot applied, polymer modified, resin-based compound incorporating a mixture of selected aggregates and fillers. The use of Ultra-Band fill and overbanding has been prolonging the life of Richmond Road in the Royal Borough of Kingston upon Thames. It has offered superior crack filling and sealing properties along with effective adhesion to all nonporous bituminous and concrete surfaces.

Key Benefits

Additional areas of multiple cracks were treated using the Ultra-Screed material.
This approach has sealed the surface cracking and provided a high skid resistance along with a smooth surface, improving the ride quality of the carriageway.
The works have significantly extended the life of the carriageway in a way that provides greater value for money than more invasive repairs.
The overbanding technique is also much quicker than other repair techniques, reducing the impact on the travelling public and local residents. The fast-curing material allows flexibility with traffic control and traffic movements, keeping delays to a minimum.
The works have given Kingston upon Thames the confidence that the life of the carriageway has been significantly extended.

Construction value: £26.5k

Client: National Highways P.C Tarmac

Key dates: March 2023 – April 2023

Project Overview

National Highways required essential works between Junction 29 and Junction 33 to improve safety. Works included barrier replacement, drainage renewal, resurfacing, road studs, road lining placement, and other safety improvements. The work will contribute to the life expectancy of the road and make journeys safer for motorists.

The work is part of National Highways’ Concrete Roads Framework and saw Tarmac partnering with WJ Group to resurface the road and make it safe, sustainable, and durable.

Project Specifics

Taylor Woodrow trading as ESM worked with WJ’S South to complete patch repairs and joint sealing along the A12 between Junction 29 and Junction 33 North and South bound covering 6,810m of carriageway repairs on road construction joints.

The team used Maxi-Crete F20, an inlaid crack repair. This is a pre-mixed hot applied, high modulus, polymerised resin compound incorporating fillers, aggregates and rubber and other mineral fillers which meets friction and texture depth requirements.

The use of Maxi-Crete F20 enabled WJ’s lining team to re-install rib line and centre white lines.
Works were carried out over 19 night shifts through A12 road closures organised by National Highways. Carrying out as much work as possible along the A12 will prevent the need for further closures in the near future.

The team also completed all recessed jointing.

Case Study: Joint sealant, overbanding, and concrete repair framework

Construction value: £280k

Client: Volker Fitzpatrick (USAF)

Key dates: 2021 – Present

Project Overview

Volker Fitzpatrick are one of the principal contractors on a new Ministry of Defence (MOD) construction framework. As part of this we support them as a specialist contractor on the United States Air Force (USAF) joint sealant, overbanding and concrete repair framework.

Project Specifics

As a specialist contractor, our teams support on a rolling repair programme at the direction of the USAF main contractor. The main contractor has been completing repairs and renewing blast doors for hangers. As part of these works, we have been carrying out concrete repairs.

Works include the saw cut of the areas followed by the plane out. Once repairs were completed we were required to finish around the door plates. We used 40mm Maxi-Crete F20 concrete repair.

The works are in eight phases with six hangers in each phase. The team have completed Phase Four, and will be returning in may 2025 to begin Phase 5 works.

Innovation

On the main contractors request, we have been trialling the HAVi Vibration Exposure Monitoring through the HAVi watch.

The watch records the operators’ vibration exposure time over multiple tools throughout the day. the information is collated for analysis in the HAVi Total Software which continuously records the operators real-time exposure, making them fully aware of their exposure level status throughout the day, therefore ensuring that no human error can be at fault for over exposure.
