Erosion & shoreline
Erosion and backfill repair in LBI & Southern Ocean County, NJ
Tier B · 32 towns covered
Sealing joints and re-establishing backfill and drainage when the yard is quietly draining into the bay through or under the wall.
This comes up often enough on the bay that marine crews down here have a settled way of handling it.
What people notice first
- A low spot or sinkhole opening in the yard near the wall
- Soil visibly escaping through or under the bulkhead
- A patio, path, or slab settling toward the water
- Voids you can feel underfoot behind the cap
What a contractor will do
When soil is leaving faster than the wall is failing, the fix is often behind the wall rather than the wall itself: sealing the sheeting joints, adding filter fabric, and re-establishing proper backfill and drainage so the yard stops draining into the bay on every tide. Left alone it hollows out the ground behind the wall and eventually takes the wall with it.
$2,000 – $12,000 — typical range, not a quote. What your home needs can only be settled by a registered contractor who comes out and looks at it.
Permitting sets the timeline here. Work on tidal water needs an NJDEP waterfront development or CAFRA approval and tidelands documentation on top of the municipal permit — often longer than the build itself. A crew that works these waters should walk you through what your lot needs.

Towns we cover for this
Only the areas where this work actually applies.
Lagoon & canal communities
Dredge-and-fill neighborhoods where nearly every lot has a bulkhead on a sheltered canal. The dense heart of the work.
Open bayfront
Mainland and bay-edge shorelines with real fetch, where wave energy is high and riprap comes up as often as a vertical wall.
Barrier island & inlet
Long Beach Island end to end, from Barnegat Inlet down to Holgate — high exposure, salt air, working waterfront, and the biggest replacement jobs.
Northern barrier island & bay
The northern barrier island strip — Lavallette and Ortley Beach — where the work sits on the bay side and takes fetch straight across open Barnegat Bay from the west.
