mumps try not to be inpatient as all the help on this site comes from working men who give there time for free, we all have our own buisness or are employed in the industry,most reply come in evening,we have a couple of tarmac experts around davel,bobbio,and a few others, a pic will help to advise the problem MSH

saying tarmac, which is a trade name is very generic.

bitmac asphalt etc is what we refer to it as, did you not have a written spec which stated 100mm of 40mm base course, topped off with 30mm of 6mm wearing course etc.

if the contractor doesn;t know what he laid then i dont hold out much hope.

[bobbi o]

is it spray and chip? ie: have they sprayed liquid bitumen on the existing surface and then spread chips on top?

if not ask to see the ticket from the asphalt plant they got the material from.even the gypos know the difference between the different materials available.

i presume they are a reputable contractor?

thanks gb groundworks for your reply is that what a reputeable firm would have suggested to put down on an existing concrete base drive mumps

[GB_Groundworks]

i only patch holes we dig in bitmac, or lay base with a 360 digger.

i sub in our surfacing lads to do any bitmac work leave it to the pro's, bobbi o and Dave_L or big jim are the surfacing lads on this forum.

bobbi o would you have recomended spray and chip on an existing and extended concrete drive and yes they were a supposedly reputable firm

no,its no use for a driveway.

i'm not replying again unless you post a pic. save a lot of fannying around guessing whats been laid on your drive.

It's very hot here in the UK at the moment - this is causing some problems with freshly laid tarmac drives etc - so patience is key here.

A picture would be ever so handy!
