A disciplined field operation serving serious clients across public and private sectors.
Seylone is a Northeast-based field services firm operating across eight states. We self-perform across two divisions: Construction Group (coring, probing, selective demolition, site clearing, surface restoration) and Earth & Civil Group (test pits, subsurface utility engineering, vacuum excavation, and specialty drilling programs).
Certified DBE, MBE, and SBE. Built for work where conflicts matter and documentation is non-negotiable.
Two divisions. One uncompromising standard. Every service, self-performed.
