Crushed drain rock is natural, angular grey rock most commonly used for backfill and drainage, but ideal for applications of all sorts – residential and commercial.

The images below show our client’s back alley parking pad core which we rebuilt. We began by grading the soil’s surface and then layed compact road gravel and topped with 20mm crushed drain rock as the top layer choice.

Rock is normally sold by the cubic yard. If you need to calculate the amount of rock your project needs, please use our material calculator. All you have to do is enter in your width, length and depth in feet. https://www.calgarylandscapesupplies.ca/rock/
