Concrete Foundations

Concrete foundations

BedRock Siteworks brings your site to a level grade. Concrete is strong, durable, and is the best solution for horse barns, pole barns, garages, cabins, and sun porches. The type of foundation that’s best for your situation depends on the type of building that you’re installing. We work with you to determine which of the concrete foundation options best meets your budget and is best for the characteristics of your site. For sloped area’s a retaining wall may be needed to extend the level area.

There are four types of concrete foundations: the Gibraltar, concrete pillars, floating slab, and graduated slab. Feel free to contact us for guidance through the process regarding specific detail’s on which foundation may be best for your situation.
