Big Timber, Montana · Serving Billings to Bozeman
Insulation, concrete lifting & waterproofing for Montana's toughest climate
Olympus Insulation installs spray foam, batt, and blown-in insulation, lifts and levels sunken concrete, and protects foundations with spray-applied waterproofing — one licensed, insured crew for the whole job, anywhere along the I-90 corridor.
What we do
Four trades. One call.
Most outfits between Billings and Bozeman do one thing. We handle the building envelope end to end — insulation up top, level concrete underfoot, and a dry foundation below — so you're not juggling three contractors on one property.

Spray Foam Insulation
Closed-cell and open-cell spray foam for walls, attics, crawl spaces, shops, and pole barns. The tightest air seal and highest R-value per inch you can put in a Montana building — and the best defense against −30° winters and wind-driven drafts.

Batt & Blown-In Insulation
Budget-friendly fiberglass batts and blown-in attic insulation for new construction, remodels, and attic top-offs to R-49 and beyond.

Concrete Lifting & Leveling
Polyurethane foam lifting for sunken driveways, sidewalks, garage floors, and shop slabs — done in hours, at a fraction of replacement cost.

Waterproofing & Spray-Applied Coatings
Spray-applied foundation waterproofing, dampproofing, and protective coatings that keep basements and crawl spaces dry through spring runoff and freeze-thaw cycles. Applied clean and fast on new builds and retrofits alike.

Built for Montana
Local crews who know what winter does to a building
We live and work in Sweet Grass County. We've seen what a −30° cold snap does to an under-insulated attic, what spring runoff does to an unsealed foundation, and what frost heave does to a driveway slab. Every product we install is chosen for this climate, not a national catalog.
- Straight answers on cost. We publish typical price ranges and explain exactly what drives your number up or down.
- One crew, whole envelope. Insulation, concrete, and waterproofing scheduled together — fewer trips, less markup.
- Backed by Terland Enterprises. The same family behind Synergy Concrete and Titan Sand & Gravel, serving Montana builders for over 25 years.
