Balfour Beatty is working in partnership with East Sussex County Council to manage the highways service across East Sussex. As part of this, we will be carrying out carriageway stabilisation works on the A22 London Road, Forest Row.

When do they start?

Works will take place between Tuesday 28 May and Saturday 22 June. We will inform you of any changes to the dates or times via advanced warning signs on site.

What are we doing?

We will be resurfacing the carriageway and stabilising sections of the underground structure (sub-base). We have previously carried out investigations here, using ground penetration radar (GPR), to gain more insight into the condition of the sub-base. The results show that the carriageway has been previously constructed of largely construction material which has allowed it to move.

To rectify this, we are using a relatively new method of repair - Geopolymer Injection. The polymer is injected from surface level, into the sub-base where it expands, displacing loose soil and filling empty spaces. It then solidifies, creating a stable, durable structure that strengthens the overall carriageway.

Prior to the application of geopolymer we will be carrying out some repair to some drainage pipe in this section, using a lining method which is certified by the water research centre. This is to ensure the polymer resin does not sip into the pipe on application.

This innovative stabilisation method is a quicker and more environmentally friendly way of addressing the movement of sub-base materials which has historically caused this section of London Road to deteriorate. It also reduces the works duration by around 50%, thereby reducing the impact of disruption to the local residents, businesses and general public.

As part of these works, we will also be resurfacing the full width of the carriageway. As part of this, works will include:

  • Removing and replacing the existing road surface,
  • Iron works replacement and/or adjustment – to include manhole covers and gullies,
  • Road Marking reinstatements,
  • Gully cleansing,
  • Minor kerb repairs,
  • Replacement of High Friction surface.

How will this impact highway users?

The team will be working between the junction of Priory Road and the Wall Hill Road junction.

Tuesday 28 May – Wednesday 5 June – The road will remain open with temporary traffic signals in place between 7am and 7pm.

The road will also be closed to through traffic between 7pm and 7am each night. A diversion route will be in place via A22, A264, A26, A22 & vice versa.

Thursday 6 June – Saturday 22 June - The road will be closed to through traffic between 7pm and 7am each night. A diversion route will be in place via A22, A264, A26, A22 & vice versa.

If you need vehicle access, please discuss this with the team on site.. Please bear in mind, there will be delays whilst the area is made safe and your vehicle is escorted by site marshalls. Access for emergency vehicles will be maintained at all times.

Information for residents and businesses

Parking: If required, we will put out ‘no parking’ signs and cones on the site to advise where parking is restricted. Please avoid parking in these locations as it will delay our works.

Weather: All of these works are subject to favourable weather conditions, for example heavy rain may affect the progress of the works.

Properties close to the carriageway may experience a temporary disturbance as this can be a noisy process and those properties may experience flashing lights and reversing sirens.

Permit Reference: EA001HM-0121-RDCL-02

We would like to take this opportunity to apologise in advance for any inconvenience or disruption this work may cause, however this forms part of our continuing improvement for the East Sussex highway network.

Please let us know how we did by leaving feedback. Please note you will be redirected to the East Sussex County Council consultation website.
