Structurally Sound Foundations for Lasting Results

When Three Little Pigs Masonry is hired to install flagstone, the existing foundation must be sound or the life of the final product will be short. What is a sound foundation? The foundation must have been installed with all the necessary and essential components for it to withstand the earth’s shifting and our climate (frost).


Preparing the Foundation

Our method of preparing the foundation for any stone application and or new concrete pad or sidewalk is in accordance with the more stringent National Building Code standards. We actually drill 4 foot deep holes (below grade) that are 10 inches to 12 inches in diameter and at 5 foot intervals. We install 15M steel rebar into the pilings and tie this steel 15M rebar to a minimum 6 inch concrete slab. While preparing the concrete slab, wire reinforcement is also installed and tied to the 15M steel rebar for vertical reinforcement. The wire reinforcement is placed overlapping within the concrete to provide the horizontal reinforcement.


We pour or place the concrete and the new concrete is ready for use. Projects that include flagstone installation require s concrete curing period. We pour or place the concrete and wait a minimum of 28 days for the concrete to fully cure. Concrete must be left to cure to avoid possible cracking if stone is installed immediately. After the curing period, we return and install your natural stone or flagstone. If these steps are not followed accurately, the chance for your flagstone to crack is a very definite possibility.


We back up our foundation installation with a 20 year warranty.
