Horizon's Time-Tested System

How it Works
The steel foundation underpinning system is a method that utilizes steel pipe pilings to permanently support structures experiencing differential foundation settlement. The steel piers are hydraulically driven through non-supporting soil until they are embedded in bedrock or bearing material is verified.


The new foundation element thereby transfers the weight of the structure through non-supporting foundation soil to a competent underlying material. The piers can be effective to a depth in excess of 100 feet. A professionally engineered cathodic protection system is designed and affixed to the completed installation to protect the piers from the corrosive action of the soil

 

 

 

What We Do

Installation
The steel piers are positioned according to engineered structural calculations for allowable bedding movement capacity of the footing and structural loading on each pier. The piers are typically calculated to be spaced and installed at 5 to 1O feet on center around the perimeter of the foundation. An excavation of approximately 2 x 4 feet is made alongside the foundation where the piers are to be installed. A strong structural steel weldment angle bracket is then placed under the footing and permanently installed with specially designed locking bolts.

Carbon steel tubing is then mounted under the hydraulic ram. The 3-foot pier sections are then driven through the bracket assembly into the ground by hydraulic pressure. Additional 3-foot sections of tubing are aligned and tightly attached by steel connectors as the pipe support column is lengthened to allow it to be driven through non-supporting soil, until bedrock or load bearing strata is reached.


Geotechnical Inspection

Verification of Bedrock or Bearing Material
A geotechnical inspection is generally performed prior to commencement of construction which usually determines the depth to bedrock or bearing material. The installation of each pier is closely monitored and documented to assure the pipe piles are embedded to a depth determined to be bedrock or bearing material. Additionally, the piers are always driven to a minimum resistance of 3,000 psi. (24,000 lbs. of force).

Why is Horizon Better?

Steel Pier System
Horizon uses a time-tested system which has been in use for over 30 years. Most other systems simply reinforce the foundation by using a concrete spacer between the earth at a slightly lower level. Concrete can shift and settle again. Steel piers securely support the house or building to bedrock or equal load bearing strata ... assuring that there will be no further vertical settlement of the foundation in the area where steel piers are installed. The system is recommended by many of the top professional geotechnical and structural engineers to permanently stabilize and re-level structures that have undergone distress caused by excessive foundation settlement.

No Lengthy Construction Schedule
Construction time varies with the amount of distress usually ranging from 4 days to 3 weeks, much shorter than comparable alternative techniques.

Non-Disruptive
A significant advantage of the system is the minimal disruption to the project site. Large-scale excavation or demolition is not required and most established landscaping goes undisturbed. The high-pressure hydraulic equipment operates quickly and quietly so that neighboring properties experience little disturbance, if any. Lastly, the procedure is non-invasive, in most cases the occupants are not required to vacate the premises when work is in progress.

Cost Effective
Our system is consistently lower in cost than other reputable and commonly used methods of stabilization and re-leveling due to the fact that steel piers do not require extensive excavation, costly labor or unnecessary delays to complete cosmetic repairs.
