Retaining Wall Contractor for Sloped Yards in York, PA
Engineered segmental walls that hold a grade, drain properly, and turn an unusable slope into flat ground.
What it is
A retaining wall holds soil back. The load on it is not just weight — it is saturated soil after a three-inch rain, which is dramatically heavier than dry soil. That is why drainage behind a wall matters as much as the block in front of it.
Our walls get a compacted leveling pad, a buried first course, clean drainage stone behind the block, a perforated drain line daylighted where it can run, and geogrid reinforcement tied back into the soil when height and load call for it. Taller walls get tiered instead of pushed past what the system is rated for.
What J-Mar does
- Segmental block retaining walls in Techo-Bloc systems
- Tiered walls to convert steep banks into usable, level lawn or patio space
- Drainage stone, filter fabric and daylighted perforated drain behind every wall
- Geogrid reinforcement where height, slope or surcharge requires it
- Steps, corners, caps and integrated lighting
- Replacement of leaning, bulging or failed walls
The process
How this job runs.
- 01
Measure the grade
Height, slope above and below, and what sits behind the wall determine the design.
- 02
Excavate & pad
Dig back, cut the trench, and compact a level base pad below finished grade.
- 03
Build & backfill
Course by course, with drainage stone and reinforcement placed as the wall goes up.
- 04
Cap & finish
Cap course adhered, grade restored above and below, and the site seeded or planted.
