Methods to prevent soil erosion and stabilize seawalls

A method of forming a chemical footer for a new seawall comprising:

• injecting an amount of a polymeric material to an injection depth at each of a plurality of spaced locations along a length of a landward side of the new seawall constructed without a filter fabric, wherein the new seawall is a seawall that has been constructed within 12 months and before substantial soil erosion has occurred;
• wherein the injection depth is from 1 foot to 3 feet below the mudline at the new seawall, and
• wherein the plurality of spaced locations are separated by a distance such that injections of the polymeric material at each of the plurality of spaced locations form a substantially continuous application of the polymeric material along a length of the new seawall.

A method of reinforcing a new seawall with a chemical whaler, the method comprising:

• injecting an amount of a polymeric material to an injection depth at a plurality of spaced locations along the landward side of the new seawall constructed without a filter fabric, wherein the new seawall is a seawall that has been constructed within 12 months and before substantial soil erosion has occurred;
• wherein the injection depth is substantially at the vertical midpoint between the mudline and the top of the new seawall, and
• wherein the plurality of spaced locations are separated by a distance such that injections of the polymeric material at each of the plurality of spaced locations form a substantially continuous application of the polymeric material along the length of the new seawall.
