Behind every seawall, groundwater and storm runoff build up, creating hydrostatic pressure that can push, crack, or even topple the structure. Without proper drainage, even the strongest seawall is at risk. That’s why Seawall Medic installs and maintains Jet Filter drainage systems — a proven solution for keeping your seawall healthy and your property safe.
When water can’t escape, pressure builds up behind the seawall. Over time, this leads to:
Restoring or upgrading drainage is one of the most effective ways to extend the life of your seawall and prevent these issues before they become disasters.
Jet Filters are specialized, one-way drainage systems designed for seawalls. They:
You don’t have to guess. Let us inspect your seawall and tell you what’s happening behind it.
Jet Filters are designed to relieve hydrostatic pressure by allowing trapped water behind your seawall to drain safely into the waterway. Without this drainage, pressure builds up and can cause cracking, bowing, or even failure of the wall. Jet Filters also feature a built-in geotextile fabric that prevents soil loss and washout.
Signs of poor or failing drainage include:
If you notice these signs, it’s time to schedule an inspection.
Jet Filters require periodic cleaning to ensure water flows freely. We recommend an annual check, though heavy rainfall or storm seasons may require more frequent maintenance. Our team can perform quick, non-invasive cleanings to keep your filters working like new.
Yes. Jet Filters are designed to work with both new and existing seawalls. Our installation process is non-invasive and can significantly extend the lifespan of an older wall by preventing ongoing water pressure and erosion issues.
Unlike basic weep holes, Jet Filters:
Most installations can be completed in just a few hours, depending on the number of filters needed and the condition of your seawall. We’ll give you a clear timeline after your free on-site evaluation.
