Fact: Bedrock SINKS! How do I know this? I was called several years ago to come look at a home in Blue Springs, Missouri that was sinking on the backside of the home. Long story short, I was contracted to Raise and Stabilize the backside of this home using the “KING PIER SYSTEM“. Once down to the footing I noticed I could not dig down any further. The King Pier System is designed to go 49″ below the existing footing by digging out a 36″ x 36″ square hole straight down to the footing, then down another 49”. Once down 49″ below the footing we begin to bore the topsoil out that the footing is sitting on. Generally residential footings are 2′ wide and 6″ to 8″ thick.  Most residential footing I find are insufficient in size and strength to hold a home especially during a bad drought like we experienced in 2012.   The King Pier Technology is saving homeowners and business owners of COMMERCIAL buildings thousands of dollars of FOUNDATION PIERING.  Back to explaining that BEDROCK does sink. The footing at the house in Blue Springs, Mo. was sitting on BEDROCK, but yet the sliding door was visually off level and would not open.  Using a Jack Hammer we broke the sunken bedrock up and pulled it out of the hole. The bedrock was only 6″ thick. We then began to dig down to the King Pier design of 49″ below the footing. We then placed a 2′ x 3′ – 1/2″ Steel Load Bearing Plate onto the sub-grade. Then we order high strength concrete to be poured over the steel load bearing plate. Once this is done we will let the concrete cure for 24 hours.  The next step would be to place another 2′ x 3′ – 1/2″ Steel Load Bearing Plate onto the previously poured High Strength Concrete. I then place 3 – 50 ton Hydraulic bottle Jacks onto the Load Bearing Plate. We get the Hydraulic Jacks tight against the underside of the existing footing. Laser levels and shots are taken prior to lifting the footing/foundation back to its correct level elevation. Once the footing has been raised, we lock the 2 outside hydraulic jacks to hole the footing and unlock and release the pressure off of the middle hydraulic jack. Once the pressure is released we pull the hydraulic jack out of the hole.  I then place the KING PIER in between the 2 outside remaining hydraulic jacks.  Using steel shims we fill the gap between the top of the KING PIER and the bottom of the existing footing until it is solid and tight. I then release the pressure off of the outside hydraulic jacks and pull them out of the hole. The final step to installing the KING PIER is to order a 2nd load of high strength concrete to fully encase the King Pier up to the TOP of the FOOTING. When the King Pier is complete the King Pier will be 4 Cubic Yards of High Strength Concrete fully encased around 300 pounds of steel (2 – load bearing steel plates & 1 King Pier). No other foundation pier system comes close to strength, longevity and size.  The King Pier System was designed and Engineered by Jim King. For more information on the King Pier, give me a call or e-mail.

Each King Pier contains 4 Cubic Yards of High Strength Concrete Fully encased around 300 pounds of High Strength Steel after the footing has been raise to its correct level elevation.
