What's included
What our retaining wall service includes
Every retaining wall project is different, but most include the following. We'll confirm the exact scope in your written estimate.
✓
Site assessment and design
We evaluate your slope, soil, drainage, and load requirements. Then we design a wall that meets IBC standards and fits your budget. You get a clear plan before we start.
✓
Permitting and engineering
For walls over 4 feet, we handle engineering and permits through Clackamas County. We coordinate inspections so you don't have to.
✓
Excavation and base prep
We dig the trench, compact the base, and set the first course. Proper base prep is critical for a wall that won't settle or lean.
✓
Drainage installation
We install gravel, filter fabric, and perforated pipe behind the wall. This moves water away and prevents hydrostatic pressure from damaging the wall.
✓
Wall construction
We build the wall using concrete block, natural stone, or veneer. We use reinforcing steel where needed and check alignment at every course.
✓
Backfill and cleanup
We backfill with compacted gravel, cap the wall, and clean the site. You get care instructions and our workmanship warranty.
How it works
Our retaining wall installation process
01
Call and site visit
You call (855) 947-9500 or request an estimate online. We schedule a visit within 48 hours, usually same-day for urgent issues. We walk your property, check the slope, soil, and drainage, and take measurements. You get a written estimate with a fixed price before we start.
02
Design and permitting
We design the wall based on load, soil type, and height. For walls over 4 feet, we bring in engineering and pull permits through Clackamas County. You see the plan, materials, and timeline. We handle the paperwork so you don't have to.
03
Excavation and base prep
We dig the trench, compact the base, and set the first course of block or stone. This is the most critical step. We use a mason's level and line to keep everything true. We also install drainage gravel and pipe behind the wall to manage water.
04
Wall construction
We lay block or stone course by course, using mortar hoes, trowels, and jointing tools. For natural stone, we cut with wet saws and angle grinders for a tight fit. We check alignment constantly. Most walls go up in 2-4 days, depending on size and access.
05
Backfill and cleanup
We backfill with gravel, compact it, and cap the wall. We clean the site, haul away debris, and walk you through the finished work. You get care instructions and our workmanship warranty. Final payment is due only after you're satisfied.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Mason's level and line
Used to keep every course level and straight. Essential for walls that look clean and perform structurally.
Wet saw and angle grinder
For cutting concrete block and natural stone to precise dimensions. We use these for tight fits and decorative caps.
Mortar hoe and trowel
For mixing and applying mortar. We use these for block walls and re-pointing existing mortar joints.
Plate compactor
For compacting the base and backfill. Proper compaction prevents settling and keeps the wall stable.
Reinforcing steel and concrete block
We use steel rebar and core-filled block for structural walls. This meets IBC requirements for load-bearing walls.
Belgard and Techo-Bloc systems
We use these brands for segmental retaining walls. They're engineered for stability and come in a range of styles.
Sakrete and Quikrete mortar
For strong, consistent mortar mixes. These brands perform well in Oregon's wet climate.
Real results
Before and after.
Eroding slope to terraced garden
Before
A homeowner in Ardenwald had a steep backyard that washed out every winter. Soil was piling against the foundation, and the yard was unusable.
After
We built a 4-foot retaining wall with drainage and a second tier to create a flat garden area. The erosion stopped, and the homeowner gained 400 square feet of usable space.
Leaning wall rebuilt with steel
Before
A 6-foot wall on Lake Road was leaning 3 inches toward the house. The base had settled, and water was pooling behind it. The homeowner was worried about collapse.
After
We removed the old wall, excavated to a deeper footing, and rebuilt with reinforced concrete block and a new drainage system. The new wall is plumb and engineered to last.
Crumbling brick wall restored
Before
A historic brick retaining wall in Downtown Milwaukie had spalling brick and missing mortar. Water was getting in and causing further damage.
After
We replaced 40 damaged bricks, re-pointed all mortar joints, and applied a breathable waterproof coating. The wall looks original and is structurally sound.
