Our teams delivered emergency refuge areas on the M25 to increase driver safety.
Scope for bay 02:
- site clearance
- lay, level and compact sub-base
- level and prepare the formation
- drainage: bespoke oil separation chamber, attenuation pipes, combined kerb drainage, filter and slot drains
- construct ‘RediRock’ modular block retaining wall 2m high, 70m long
- ducting and infrastructure for NRTS emergency telephones and vehicle detection hardware. This indicates to the control centre if a vehicle stops in the area, so the emergency services can assist them if necessary
- topsoil and landscaping
- asphalt surfacing
- orange high friction surface coating
Redi-Rock wall blocks are a modular system for retaining walls. We installed the blocks onto a mass concrete foundation. We placed 10mm shingle between the blocks and back of wall fill, separated by geotextile to facilitate back of wall drainage.
