Your Coverall replacement, re-engineered.
Coverall Canada closed in 2010. Building Depot supplies the modern engineered replacement — the MegaDome® — and re-covers existing Coverall, ClearSpan and Britespan frames across Ontario.

Replace the building — or just the fabric.
If your Coverall frame is sound, we tension a new 22 oz architectural PVC skin with a fresh 25-year warranty. If the structure has fatigued, we replace it with a MegaDome® HHP or XP series — a hot-dip galvanized, P.Eng-stamped modern equivalent that will outlive the original by decades.
- →Frame audit and load-check before quote
- →Concrete repair, anchor retrofit, cable tensioning
- →Fabric colour and translucency to match existing site
- →Turnkey — no coordinating a re-cover crew and a builder
