Yes, we do foundations of all shapes and sizes including additions and remodels.
At Colossal we pride ourselves on producing foundations within a 1/4 inch of being perfectly square. This can save as much as 10% of the entire cost of building!
Wether we need to Cliff hang and build your foundation on the side of a mountain, or you need a 60’x200′ Steel Structure Foundation slab, we can build it.

We are unions certified in patching of concrete and can replace sections to save money when needed. Call for more details.
