Retaining Walls in Kenner

Kenner is famously flat, so people sometimes assume retaining walls don’t belong here. They do, just for different reasons than you’d find in hill country. On a flat, low lot near Lake Pontchartrain, a retaining wall is mostly about managing water and creating definition: a raised planting bed that drains, a low terrace that lifts a patio above a soggy yard, or a clean border that keeps mulch and soil where they belong.

Walls That Work With Kenner’s Water Table

The water table runs high across most of Kenner, and the soil is soft alluvial delta that holds moisture. That changes how a wall has to be built. Water pressure behind a wall is the number one reason walls fail, and on saturated Kenner ground that pressure is real even on a short wall. We build with drainage baked in, not added as an afterthought.

How We Keep Walls Standing

• A compacted crushed-stone base sized for soft, damp sub-grade
• Free-draining gravel backfill behind the wall so water doesn’t build up pressure
• A perforated drain pipe at the base that carries water out to daylight or a drain
• Geogrid reinforcement tied back into the soil on taller walls for long-term stability
• Segmental block units that interlock and flex slightly with ground movement

Where Kenner Homes Use Retaining Walls

Most residential walls here are low and practical. A raised garden bed along a fence line lifts plant roots above the wet zone so they don’t drown after heavy rain. A short terrace turns a flat backyard into defined levels, which makes a patio or seating area feel intentional instead of plopped on the lawn. A wall around an HVAC pad or pool equipment hides the clutter and keeps mulch out. Near the lakefront and in subdivisions like Chateau Estates, we also build low walls that frame a driveway or entry and give an otherwise flat front yard some structure.

Segmental block comes in colors and textures that match the rest of your hardscape, so a retaining wall reads as part of the design instead of a gray industrial slab. We can match a wall to an existing paver patio or driveway for a cohesive look.

Permits and Engineering in Jefferson Parish

Low decorative walls are usually simple, but once a wall reaches a certain height or holds back a meaningful load, the Jefferson Parish Department of Inspection and Code Enforcement may require a permit and engineered plans. We know where that line sits, handle the permitting, and bring in engineering when a project calls for it. That protects you and keeps the wall from becoming a liability down the road.

Built to Outlast Poured Concrete

A poured concrete wall on Kenner’s shifting soil cracks and is a nightmare to fix. A segmental block wall flexes, drains, and can be repaired course by course if it ever needs attention. If you’ve got a wet low spot, a planting bed that keeps washing out, or a flat yard you want to give some shape, we’ll look at how water moves across your lot and design a wall that holds.
