Our story

Raised on farms.
Built on
doing it right.

S.E Grading & Contracting is Ethan Dewe's earthworks and roading business, based in Renwick and working across Marlborough, from Nelson to Kaikōura. Ethan has been in earthworks and roading since he was 15, starting out on public roads before moving into large earthworks, vineyard developments, forestry roading and civil work.

Nearly four years ago he started S.E Grading. Today Ethan and the team run an 8 tonne and a 20 tonne digger, a grader, two truck and trailer units and a transporter, plus their own hard rock quarry. Fully insured, with free quotes usually out within 24 hours.
