Commercial Tarmac Laid In Newbridge
A car park or industrial yard in Newbridge takes around 150mm of tarmac, over 200-300mm of sub-base. We always take the sub-base up with the surface, because a thicker layer of tarmacadam on a domestic sub-base is still not heavy duty.
That depth of around 150mm is the total, and the target is the same whether the tarmac is laid as one course or two.
What Commercial Tarmac Work Do We Cover In Newbridge?
These are the commercial areas Carlow Builders lays in tarmac and asphalt around Newbridge:
- Car parks
- Private estate roads
- Yards and industrial areas
Each job starts on a new crushed-limestone 804 foundation, graded, with drainage put in where the job needs it.
On top is either a standard tarmac wearing course of around 20mm, or a finer 6mm finish in stone mastic asphalt, known as SMA. Of those, the 6mm finish closes tightest and stands up best to tyre scuffing.
We can add granite bordering, concrete kerbing or paved entrance aprons. An edge with nothing holding it fails first, so the tarmac is laid into an edging kerb or a border, and where neither is possible the edge is chamfered down hard to seal it.
Laying Commercial Tarmac Properly
Our contractors compact the 804 base with a vibrating machine roller of around 20 ton, then the tarmac is laid hot in two courses, the base (binder) course first and the surface (wearing) course over it.
Tarmac bonds to itself as it is laid, so once we start on an area we keep going until it is finished or reaches a change of surface. On a large car park in Newbridge the stopping points are planned before laying starts.
Standard tarmac is not permeable and water must never pool on it. We set the falls to run surface water into channel drains, connected into the existing drainage or a soakaway.
