Retaining Wall Installation
Southern Wisconsin’s freeze-thaw cycles and clay-heavy soils put serious pressure on retaining walls, and a wall that’s built without accounting for drainage will lean, crack, or fail within a few years. Martinez Landscaping installs retaining walls sized and engineered for your specific slope, soil type, and load conditions — whether you’re holding back a hillside, leveling a yard for usable space, or stopping erosion along a driveway. Every wall we build uses proper base preparation, compacted gravel backfill, and drainage aggregate so it stays plumb through Wisconsin winters.
- Block, natural stone, and boulder wall options sized to match your yard’s slope and the load it needs to hold
- Excavation and graded base preparation done to the correct depth for frost protection in Wisconsin’s climate
- Compacted gravel base and drainage aggregate installed behind every wall to prevent hydrostatic pressure buildup
- Battered (angled) course layout on taller walls for long-term structural integrity, not just appearance
- Backfill compacted in lifts so the soil behind the wall settles correctly without pushing out the face
- Wisetack financing available — 0% APR options for qualifying projects, so you can address erosion or grading issues now
How It Works
Our Process for Retaining Wall Installation
Free written estimate with site assessment
We visit your property, measure the slope and run length, check soil conditions, and give you a written estimate detailing wall height, material, and drainage plan. No verbal quotes.
Material selection and project scheduling
You choose your wall material (concrete block, natural stone, or boulders) and we lock in a start date. We pull any required permits if the wall height triggers local Oconomowoc or Waukesha County requirements.
Excavation, base prep, and wall installation
We excavate to proper depth, compact a gravel base, and build the wall course by course with drainage aggregate backfilled as we go. No subcontractors — our crew handles every step.
Final grading and site cleanup
After the wall is complete we grade the area behind and in front, compact the soil, and clean up all debris and excess material. We walk the finished wall with you before we leave.

Common Questions
FAQ: Retaining Wall Installation
Most municipalities in Southern Wisconsin require a permit for retaining walls over 4 feet tall measured from the bottom of the footing. We check the specific rules for your city or township before we start and handle the permit process if one is required.
Concrete segmental block (like Allan Block or Versa-Lok) holds up well through Wisconsin freeze-thaw cycles and is the most common choice for walls under 4 feet. Boulder walls work well for larger slopes and a natural look, but cost more to install due to equipment needed.
A properly built wall with good drainage behind it should last 20 to 40 years or more. Most early failures come from inadequate base depth or no drainage aggregate, which lets water and frost pressure build up behind the face.
