Patent ID: 8579548

Claim:
A method of remediating an in situ piling comprising the steps of: providing an in situ piling having a lower portion embedded in the ground and an upper portion with a top surface extending above the ground, the piling having outer surfaces; drilling a centered channel of given diameter into the in situ piling from the top surface into the piling; providing a second piling with a bottom section having a given diameter, said second piling having a centered channel substantially equivalent in diameter to the diameter of the channel drilled into the in situ piling; planing a section of the outer surface of the in situ piling to a diameter substantially equivalent to the diameter of the bottom section of the second piling; providing an elongated steel rebar having a diameter smaller than the diameter of the channel; inserting the rebar into the channel of the in situ piling, such that a first section of the rebar extends partly within the piling and a second section of the rebar extends out of the piling and a space is created between the rebar and the channel; providing a connection sleeve having an external diameter greater than the diameters of the planed section of the in situ piling and the bottom section of the second piling; positioning the connection sleeve over the planed section of the in situ piling, thus creating a space between the planed section and the connection sleeve; positioning the second piling over the top surface of the in situ piling; inserting the rebar into the channel of the second piling; placing the second piling on the top surface of the in situ piling such that the outer surfaces of the pilings are in contiguous alignment and the connection sleeve extends over the bottom section of the second piling; injecting bonding material into the channels and spaces between the connection sleeve and the pilings; filling the piling channels around the rebar and in the spaces between the connection sleeve and the pilings with bonding material; and allowing the bonding material to harden to secure the pilings together.
