Currently in the middle of a long and stressful Reno of a house is Scarborough. Around November of 2017 the contractor hired some company to pave the driveway. At first glance I could tell of some deficiencies, this was brought up with the contractor at the time. Nothing was done since. Fast forward to April 2018. Weeds have started to grow through the asphalt. Can this be addressed without tearing up the entire driveway? To be honest with the terrible work done I feel like asking them to do it again.
I'm sorry to hear that this happened to you when hiring a "professional" contractor. There are many factors that may have caused this such as;
* Inadequate asphalt thickness,
* Inadequate base preparation,
* They did not place Geotextile cloth between the native clay and the granular base (this would of only been required if they had to have dug/excavated for new construction).
Typically weeds begin to grow through asphalt if it's placed over top of unsuitable base and thus organics weren't properly treated before asphalt placement or the asphalt was placed as a very thin layer.
In my professional opinion, if weeds are growing through the asphalt within 6 months of placement, this is definitely a sign of poor workmanship and should definitely be fixed by the contractor.
To their defense, you have to consider the fact that weeds can grow from simple spoors when mowing the lawn so before you challenge them, make sure it's not surface weeds.
Hope this helps your situation.
