The Polymer Seawall Repair Process:
Step 1: Assess and Prepare
Determine cause of damage, explain scope of
work to the client, protect surfaces, drill holes.
Step 2: Seal Leaks and Fill Voids
Inject enough foam to seal leaks and fill voids.
Make sure seawall has proper drainage.
Step 3: Clean Up and Review
Clean the surface and review site with client
to ensure their satisfaction.
Why Do Seawalls Deteriorate?
• The Elements
Salt corrosion, tidal action, currents, boat wakes, storm
surges and heavy rain events all deliver a constant
beating on the seawall. Every time it rains or the
irrigation system runs, and every time the tide goes out;
all of the groundwater above the waterline has to vent
or equalize. Tremendous pressures can build up if that
water is trapped and cannot make its way into the sea
or the storm water system.
• Structural Aging
Correct construction of a seawall includes a drainage
system to handle the bulk of the water that comes from
rain in addition to check valves, weep holes, or seams
to handle the daily influx and outflow from tide and
wave action. Over time the materials degrade or can be
disturbed by settling. The result is a loss of soil and the
inevitable sinkholes and / or low spots that will occur
along the wall. Other times, the weep holes and vents
become clogged and the water has no way to escape
except to force its way down and out from underneath
the base of the wall. When this occurs there will again
be sinkholes and sometimes wall failure.
How Does Polymer Foam Help?
• Non-Intrusive Application
AP Fill 700 can be injected through
pipes directly into voids and loose
sandy soil using small portable
• Proven Solution
Will seal any leaks along the wall,
fill the voids that have occurred,
and mix with the soil to form a solid,
What Are the Results?
• Long Lasting Repair
Alchemy Polymers structural foams are
stronger than crystalline bedrock. Combined
with proper drainage, this method
can greatly extend the life of your seawall.
• Water Tight Seawall
Reacts with water or moisture in the soil
and expands to fill voids while it permeates
sandy soil to form a solid, strong, watertight
• Environmentally Safe
AP Fill 700 is approved for contact with
drinking water (certified to NSF 61-5). That
means 700 can be used anywhere without
having an adverse effect on water quality.
