The ECP Steel PierTM belongs to a family of foundation repair products that are sometimes referred to as micro piles, push piers, or resistance piers. These foundation repair products are driven hydraulically into the soil using the structural weight of the building as a reaction force.
Before one can begin a discussion of soil nailing, a clear understanding of the difference between soil nails and tieback anchors is required. Many times one hears the term "Soil Nail" and "Tiebacks" used interchangeably and this demonstrates a lack of understanding of the products.
Helical piers have been in use for
more than 160 years. In 1838 a
lighthouse was built upon helical piers
designed by an Irish engineer, Alexander
Mitchell. In 1863, Eugenius Birch
designed the Brighton West Pier in
Brighton , England . These piers are
still in use 140 years later. The
original helical piers were installed at
10 feet per hour using eight 20 foot
long torque bars and the force of 32 to
40 men.
ECP Light Pole Support Anchors are an immediate foundation for at grade and above grade applications to support street, site and parking light poles. ECP Light Pole Support Anchors are installed with hydraulic rotary equipment that turn the foundation in the ground with the assistance of a helix shaped plate that acts as a screw for ease of installation.
The ECP Plate Anchors are designed to stabilize cracking and bowed foundation walls. The inside wall plate is fabricated from 10 gauge hot-rolled steel and measures 12" X 26". The wall plate has two embossed reinforcing ribs for additional stiffness, plus a 4" square, 10-gauge square washer is included for added strength.
