Tarmac Resurfacing2016-12-08T19:02:40+00:00

Resurfacing a driveway also know as a tarmac overlay is the process of installing a new layer of tarmac directly over the top of the existing layer. This is a perfectly acceptable method of doing a driveway as long as it is done properly by trained professionals using the correct materials. The basic process is:-

•  Clean existing driveway of all loose material
•  Repair any edging courses that are damaged or loose
•  Repair any minor damage on the existing surface
•  Cut any required joints to reduce heights or increase clearance
•  Make up any areas prone to water collection
•  Weed treat any problem areas if required
•  Cover existing driveway surface with Bitumen Emulsion (AKA tack coat) which bonds the new layer to the old one
•  Lay an SMA (Stone Mastic Asphalt) 6mm wearing course to an approx depth of 30mm.

Some driveways lend themselves to being resurfaced some don’t, there are a number of factors that need to be taken into account.

•  Is there room to fit another surface on top of the existing one without breaching the DPC?
•  Will garage doors etc open once a new layer of tarmac has been added?
•  Is the existing surface cracking and breaking up, if so is it repairable?
•  Is the existing surface flooding?
•  Does the existing driveway have a sound sub-base?

These are the main factors to consider when ascertaining if an existing driveway can be resurfaced, dependent upon the severity of some of the above issues it may be possible to rectify them so as to still allow a resurface.

It’s also possible to extend your existing driveway to fit more cars on whilst still resurfacing the existing section, this entails the full excavation of the area to be extended and making it up to the existing tarmac level.
