A general contractor working with a homeowners association reached out to SiteMix Pressure Grouting, LLC about a detention pond wall that was leaking along the footer in several places. A detention pond is designed to collect rainwater and then let it drain slowly in a controlled manner. But in this case, water was washing out quickly in an uncontrolled manner in multiple spots under the footing.

Repair Materials
To rapidly address the problem, the technicians at SiteMix chose AP Fill 720. This single component, closed cell, hydrophobic, water-reactive, solvent and phthalate-free, low viscosity polyurethane foam has a high expansion rate, and is ideal for filling voids. In this case, AP Fill 720 was the perfect choice for filling the soil voids underneath the footer created by water erosion.

First, the crew injected AP Fill 720 along 150 feet of the wall, installing approximately one gallon underneath the footing every two feet. Next, they installed another 75 gallons, spot treating larger voids.

The job was completed in only 2 days. The detention pond wall was ready for use immediately upon completion of the work. The general contractor and the homeowners association manager were very happy with the results.

Repairing a Leak in a Retention Pond

A property management company in metro Atlanta contacted SiteMix Pressure Grouting, LLC to address an issue with a neighborhood retention pond that was not holding water at the proper level. The customer reported that the water level was not running through the top of the concrete outlet control structure as designed, but water was exiting on the other side of the earthen dam through the concrete outlet pipe. Upon inspection, it was discovered that the pond water was piping along the outside of the concrete outlet pipe and leaking back into the outflow pipe through several bad joints in the concrete pipe.

Repair Materials
The SiteMix Pressure Grouting crew choose AP Fill 700, a single component, water-activated, hydrophobic, low viscosity, closed-cell polyurethane injection resin for the repair. Specifically, AP Fill 700 is NSF-approved for contact with drinking water, safe for the environment and allows the crew the ability to adjust the catalyst for set time. The polyurethane material is ideal for permeating soil, filling voids and water cutoff.

AP Fill 700 was injected on 18-inch centers around the base of the OCS and outlet pipe in order to inject resin into the flow of the piping water. Specifically, the set time of the resin was reduced so that the piping water would take the resin the length of the pipe to the leaking joints. The goal was to have the AP Fill 700 react from downstream back up to the OCS. Crew members observed the pipe joints until AP Fill 700 presented and all the leaks stopped.

The job took one day to complete and less than 50 gallons of resin. Within three days the pond was at full pool and the management company and neighborhood residents were very satisfied with the work. The treatment plant was extremely happy with the results.
