Seawalls embody the very image of long-lasting endurance and stability. Without proper maintenance and repair, however, the reality can be a bit different. If your seawall is showing any of the signs listed below, you may want to look into repair options.
Here some telltale signs your seawall may need repairs...
- Clogged Weep Holes
Weep holes are small openings in concrete structures that allow water from behind the seawall to drain through it. If these holes get clogged with debris, water pressure can build up and cause the wall to eventually crack and fail (or cause the water to find ways around the wall).
- Visible Rust Colored Cracks/Stains
Rebar that has been exposed to water will stain the surrounding area. This causes the rebar to expand, further introducing cracks into the seawall and risking failure.
- Sinkholes or Settling Concrete Near the Seawall
Sinkholes or settling concrete appear due to loss of soil. This is essentially a feature of a compromised seawall in that water is seeping through or underneath the seawall, weakening the structure and contributing to soil erosion.
- Sand or Soil Deposits on the Water Side of the Seawall
These deposits will typically show up at the joints and are a sign that you are losing soil from behind the seawall.
Solution - Polyurethane Seawall Repair
I summed it up in this previous blog post An In-Depth Look at Polyurethane Seawall Repair...
Polyurethane installation equipment and procedures allow for a non-invasive, clean approach to repair that often allows the property owner to continue use during the process. In all cases, the property owner can resume activity on and around the structure within hours after a repair. As explained in our blog post Alchemy-Spetec's NSF Certification Spells Environmental Protection, most of our products have been rigorously tested not only for contact with typical recreational and commercial bodies of water, but even for contact with drinking water. So there is NO doubt about the environmentally friendly advantages of Alchemy-Spetec seawall repair materials. Read more...
