Cracks in asphalt and bitumen pavements allow water and vegetation to penetrate the surface which causes pavement material failures. Failure to seal these cracks and remove vegetation will result in further cracking, potholes appearing and eventually a major pavement breakdown, leading to unnecessary expensive repairs. To minimise the water infiltrating the pavement base we recommend crack sealing with a hot polymer/ rubberised bitumen sealant, this can help to prevent future pavement problems and prolong the surface area before a full overlay or completely new surface is required. Crack sealing is a practical and cost effective measure for the maintenance of roads, carparks and driveways, when compared to undertaking other more extensive works such as resurfacing and reconstructing.
