Devcon Civil

Blacktown, NSW 2148


Devcon is a third generation family owned and operated company with decades of experience in roads, civil, concrete, drainage, kerb & gutter and associated works. Through the proficient delivery of the projects we undertake, Devcon has established itself as a highly professional company delivering on-time, high-quality outcomes in this demanding market.

Devcon was originally established in the 1950s by Allen De Vries. Allen had a reputation as a hard worker and delivering exceptionally high quality. His son Jack joined him in the ’70s and as Jack built on the business the reputation for high quality grew even further.

During the 90’s Gavin and Matthew joined Jack and then took over from Jack in the following decade, with brother Simon also joining the team.

At Devcon, the key attitude that drives the team is professionalism. This is a niche that was identified as being of high importance to this industry and one that is conspicuous by it’s absence. Through high levels of communication and relationship building Devcon sets itself apart as a company that our clients ‘want’ to deal with. Quality is of equal value to professionalism.
