Lake Oconee and Robin Lake at Callaway Gardens are two of the most significant bodies of water in close proximity to the greater Atlanta area. Do you own or manage property on either of these lakes? If you have a seawall on your property, you may want to check for the following:

• Settled soil near the wall (a sign of water leaking through the wall and eroding the soil on the land side).
• Soil deposits near the seams on the water side of the wall (a sign of water leaks bringing soil through the seams into the lake).
• Visible rust colored cracks or stains in the wall (a sign of water leaking through cracks in the wall and rusting the rebar inside).

These could all be indications that your seawall is leaking and in need of repair.  Polyurethane seawall repair is less expensive and more efficient than tearing out the wall and replacing it completely.

At GCS we use Alchemy-Spetec’s AP Fill 700 high-strength polyurethane foam on our seawall repair jobs.

Proven Strength

Impermeable to water once in place, this foam decreases the likelihood of future erosion versus refilling the void with soil or other material.

Originally developed over 30 years ago, and continuously improved since, this technology has one of the longest histories of success in the field among repair uses of polyurethane foams.

Environmentally Safe

AP Fill 700 has been approved for contact with drinking water (NSF 61-5) by Truesdail Laboratories. While no one will likely be drinking out of the lake water, this extra level of precaution means that the cured resin has no adverse effect on water quality.

Efficient Installation

Results are immediately clear due to the visible exiting of water when the foam is injected.  The foam rapidly sets in less than 10 minutes.  No heavy equipment is needed, as the foam is simply injected through pipes directly into voids and loose soil using a small single component pump.
