The company is based in Langley, BC. I assume the prices quoted were for pickup. It's about an hour's drive for me but we'd probably need to converge at the same time to be able to remove a ton of it. I have access to a 1/2 ton pickup but loading the whole thing... The truck's already pretty old!
It would be a pretty annoying road trip from Calgary to pick some up, but there might be a local distributor in AB that has it as well.. What's one of the major named sands/cements in your hardward stores? You could probably get some data from the company on other materials.
