Alliant Paving

Alliant Paving, which operates as AlliantCo, is an asphalt paving and maintenance contractor based in Tigard, Oregon. It works on industrial surfaces, private roads, commercial parking lots and residential driveways, and takes on subcontracted work for other firms alongside its own contracts.

Maintenance and repair account for most of the published service range. Crack sealing is offered to close openings before water reaches the layers beneath, and surface crack repair addresses shallower cracking. For pavement that has already broken up, the company carries out pothole patching and general asphalt patching, and performs full-depth patching where the damaged layers are removed and the section rebuilt from the base rather than covered over. Sealcoating protects against weather, sunlight and chemical exposure, and general asphalt maintenance covers surface care, sealing and cleaning.

ADA compliance repairs are handled as a separate service, correcting ramps, walkways and surfaces that no longer meet accessibility requirements. The company also sets up preventative maintenance programs for owners who would rather schedule work across a pavement's life than respond to failures as they appear.

New paving is offered as well, covering access roads, parking lots, walkways and driveways, with attention given to site preparation, grading and compaction before the surface goes down. The company works with developers, contractors and property owners, and can be reached by phone or email for scheduling and estimates.
