Weep holes are your seawall's pressure release valve. When they're clogged, missing, or not draining, pressure has nowhere to go — and something else gives instead.
Every seawall needs a way to let trapped water out from behind it. Weep holes and filters are that release valve. When they stop working, the water pressure that should be relieved safely instead builds up against the wall itself.
No visible drainage doesn't mean no water pressure — it means the pressure is building somewhere with no outlet. That's a direct path toward the cracking, leaning, and soil loss covered on the other warning-sign pages.
We clear or install proper weep holes fitted with filters designed to let water out while keeping soil in, restoring the pressure relief your wall was engineered to have.
