Service gallery
We deliver road and asphalt works as a complete engineering sequence that starts with survey setting-out and site preparation and ends with the wearing course, road marking and traffic safety works, executed to the approved drawings and to the survey plan signed off by the consultant, with inspection and conformity testing at every layer before the next one is placed.

What the service covers
- Complete layer sequence from subgrade to the wearing course

Our methodology
-
01
Survey and site preparation
Setting out the site points, levels and locations for every element, with the setting-out approved by the consultant before work starts.
-
02
Excavation and granular layers
Excavation, backfilling and compaction, then the subgrade, sub-base and base course, each with conformity testing before sign-off.
-
03
Asphalt layers
Prime coat sprayed, then a 5–7 cm binder course, followed by the tack coat and the wearing course with the required compaction.
-
04
Marking and handover
Ground marking applied and reflectors and information signs installed, then the works reviewed and handed over to the supervising authority.
