What Is a Trench Drain?
Standing water on a commercial lot or loading dock is more than a nuisance — it's a liability. Here's how trench drains work, where they're required, and what goes into a proper installation.
Asphalt Repair vs. Resurfacing

FAQ
FAQs About Altera Construction
Everything you need to know before starting your next project with Altera Construction.
What types of commercial projects do you handle?
We work on excavation, underground utility and sewer installation, parking lots, asphalt paving, and land development for organizations, developers, and property managers across Canada.
Do you handle both new site development and existing property upgrades?
Yes. That includes ground-up land development and excavation for new sites, as well as parking lot repairs, resurfacing, and utility upgrades on properties already in use.
How do you maintain quality and safety on a commercial site?
Every project follows the same process — site assessment, utility locates, a clear execution plan, and inspection at each stage — regardless of the size or complexity of the job.
How will I know what's happening during my project?
You'll have a clear point of contact and regular updates as the work progresses, so there are no surprises about schedule, scope, or site conditions.
What makes Altera Construction different?
We focus specifically on commercial site work rather than general residential construction, which means our crews, equipment, and planning are built around the needs of organizations and developers.
