Concrete Footer Calculator

Concrete footings exist to transfer the structural loads away from the deck (snow load, live load, dead load, wind load, earthquake load, etc.) and into the Earth. Obviously, the foundations on a deck are critical from a structural standpoint. However, since they are usually unseen after backfilling, too many times the foundations are built without enough attention to detail.

Understanding the support system for your deck is important, and the concrete footer system is a very significant part of the structure. Improperly built footers can be dangerous. Therefore, it is important to take the time to properly prepare all parts of your deck before starting the project.

At Silca System, we want to provide the tools for anyone to make new, beautiful, high-quality, and SAFE decks. Our engineered polymer Silca Grates provide the perfect system for sturdy outdoor stone decks. We want to make sure that our customers are provided with the best way to make the rest of their deck safe, too. Please refer to the calculator tool below to calculate the correct dimensions for your concrete footer system.

silca system stone tile deck testimonial

Silca grates allowed me to do “the impossible”. I didn’t have to worry about future problems and costs because of termites, rotting, or the effects over time of north Texas summer heat and winter freezes. “Grateful” is the appropriate word for how I feel about Silca grates! You made the impossible possible.
