Densoband flexible sealant was chosen for use in the London Gateway at Stanford-le-Hope, Essex. Sub-contractor Aggregate Industries applied 12,000 metres of black Densoband as a flexible sealant between asphalt and concrete, including concrete channels (to take away surface water), gullies and bays.
AI has completed a new project which entailed application of approximately 2,000 metres Densoband in jointing areas between asphalt and concrete on the general parking areas of the Gateway. Miles Macadam then applied a final Hardicrete grout on this park area. Densoband is a polymer modified bitumen strip which is approved for use in asphalt surface course joints for asphalt, and asphalt to concrete interface, as an alternative to the previously commonly used bitumen. Because water, salts, pollutants and weed seeds cannot penetrate the sealed joint, it remains unaffected by extremes of temperature.
