Retaining Wall Services in Davis, Weber, and Salt Lake Counties
A retaining wall does more than hold dirt back. The visible face is the smallest part of the job. Behind every retaining wall is a system of drainage, backfill, compaction, and footing support that determines whether the wall stays stable for decades or begins to lean, crack, and fail within a few years. When that system is not built correctly — or when an existing wall was built without one — the result is pressure, movement, and eventual failure that costs more to fix than it would have cost to build right the first time.
Cornerstone Custom Construction & Remodeling handles retaining wall projects across Davis, Weber, and Salt Lake counties, with 15+ years of construction experience. Whether the project is a new wall, a replacement of a failing structure, or a terraced system to manage a sloped yard, the work starts with an estimate conversation about your site, your wall, and what the wall needs to do.
Quick Answers
Who is this page for?
Homeowners dealing with a failing retaining wall, planning a new wall to manage slope or grade changes, or comparing retaining wall contractors in Davis, Weber, or Salt Lake County. Builders, developers, and property owners with retaining wall needs as part of a larger site plan or new construction project should also use this page to confirm project fit.
What does the work usually include?
Retaining wall projects commonly involve new wall construction, replacement of leaning or failing walls, terraced landscape walls, and structural walls supporting driveways, parking areas, stairs, or adjacent buildings. The work behind the wall — excavation, drainage installation, backfill, compaction, and footing preparation — is as significant as the wall face itself. Material systems include segmental concrete block, natural stone, poured concrete, and masonry, depending on the application and the loads the wall needs to carry.
What should you do next?
Call 801-389-3161 or email info@cornerstoneconstructionremodeling.com with your address, photos of the site or existing wall, and a description of what the wall needs to do. Include approximate height and length, what is above and below the wall, and whether an existing wall needs to be removed. That gives Cornerstone enough to confirm fit and move into the right estimate path.
Who This Service Fits
Retaining wall work applies when grade changes, slope conditions, erosion, or a failing existing wall are affecting how the property can be used. Common starting points include:
- A wall that is leaning, cracking, bowing, or shedding material — signs that the drainage, footing, or backfill behind it are failing
- A slope or grade change in the yard that limits usable space, causes erosion, or directs water toward the house, driveway, or neighboring property
- A new construction or hardscape project that requires grade management — holding soil behind a patio, driveway, or building pad
- A yard that needs to be reorganized into terraced levels for planting, access, or drainage control
- An existing wall that was built without proper drainage or reinforcement and is beginning to show movement
Cornerstone's requested role on a retaining wall project depends on the scope. Some jobs are straightforward wall replacements. Others involve the wall as one piece of a broader yard correction that includes grading, drainage, adjacent hardscape, or connection to other structures. The scope, the requested role, and the responsibility boundaries are established during the estimate conversation — not assumed from a service name.
Scope, Exclusions, and Representative Project Conditions
What retaining wall projects typically cover:
- New retaining wall construction — excavation, footing preparation, drainage system installation, wall construction, backfill in compacted lifts, and cap or finish work
- Replacement walls — demolition and removal of a failing wall, site correction, and rebuild with proper drainage and structural support
- Terraced wall systems — multiple stepped walls to manage longer slopes, with drainage and backfill at each tier
- Wall-adjacent grading — reshaping the grade immediately around the wall to direct surface water away and establish proper drainage flow
- Drainage systems — perforated pipe at the wall base, gravel backfill, geotextile fabric, and weep holes or surface drainage as conditions require
- Backfill and compaction — clean granular fill placed and compacted in lifts behind the wall to reduce lateral pressure and prevent settlement
- Geogrid reinforcement — synthetic reinforcement layers tied into the wall face and extending into the backfill zone for taller walls or higher-load applications
- Caps, steps, and corner conditions — finishing elements that affect both the wall's appearance and its structural performance at transitions
- Material systems — segmental concrete block, natural stone, poured concrete, and masonry, selected based on the wall's function, height, loads, and site conditions
What retaining wall work does not typically include on its own:
Retaining wall services focus on the wall, the system behind it, and the immediately adjacent grade. Engineering design — structural calculations, stamped drawings — is a separate licensed responsibility when required. Surveying, property-line determination, and geotechnical investigation fall outside the wall construction scope. Landscape work beyond the wall zone — irrigation, planting, sod, or hardscape not connected to the wall — would fall under its own service scope. Permitting, inspection scheduling, and engineering coordination depend on the project and are confirmed during the estimate conversation.
Representative project conditions:
Older or poorly built walls often reveal conditions that widen scope once demolition begins — collapsed drainage pipe, saturated clay backfill where gravel should be, no footing at all, or buried debris used as fill. Slopes with heavy clay soil hold water and increase lateral pressure on the wall, requiring more aggressive drainage design. Walls near driveways, parking areas, or structures carry surcharge loads that a landscape-grade wall is not designed to handle. Steep lots with limited equipment access may require different excavation and material-handling approaches. These conditions are common in retaining wall work, and they are part of why the estimate conversation matters before any commitment is made.
Scope Options
Retaining wall projects fall into several categories depending on what the wall needs to do and what is driving the project. The scope option determines the material system, drainage and reinforcement requirements, and overall complexity.
New retaining walls
New walls are built where no wall exists and the grade needs to be held, reshaped, or supported. Common applications include creating usable flat space in a sloped yard, supporting the edge of a patio or driveway, managing erosion along a property boundary, and organizing elevation changes for access or drainage. A new wall starts from excavation and includes the full system — footing, drainage, backfill, reinforcement where needed, and the wall face and cap.
Replacement and repair
Replacement applies when an existing wall has failed or is actively failing — leaning forward, cracking through courses, bowing in the middle, or losing material. Most failing walls cannot be repaired in place because the failure originates behind the face, in the drainage, backfill, or footing. Replacement involves demolishing the old wall, correcting the conditions that caused the failure, and rebuilding with proper drainage, compaction, and structural support. Limited repairs may apply when damage is isolated and the wall's drainage and footing remain sound.
Terraced and landscape walls
Terraced walls use multiple shorter walls stepped up a slope instead of a single tall wall. This approach reduces the lateral pressure on each individual wall, creates planting or access tiers between levels, and can avoid the engineering threshold that a single taller wall would trigger. Terraced systems require drainage at each tier and proper setback between walls to function correctly. Landscape walls also include low garden walls, border walls, and decorative grade transitions where the retained height is modest and the loads are light.
Structural and load-bearing walls
Walls that support driveways, parking areas, stairs, adjacent buildings, or other heavy loads carry different requirements than landscape-grade walls. Higher surcharge loads require deeper footings, heavier reinforcement, more aggressive drainage, and often engineered design with stamped drawings. The distinction between a landscape wall and a structural wall is not always obvious from the surface — it depends on what is above and around the wall, not just the wall's height.
Planning Inputs
The more detail you bring to the estimate conversation, the more accurate the scope and the fewer surprises during the project. Useful inputs include:
- Photos of the site or existing wall — the wall face, the top, the bottom, any leaning or cracking, and areas where water or erosion are visible
- Approximate dimensions — wall height, wall length, and the grade change being managed
- What is above and below the wall — driveway, patio, building, slope, planting area, or open yard, because loads above the wall change the structural requirements
- Drainage observations — where water pools, where runoff flows during rain, whether the base of the wall stays wet, and whether soil is washing out
- Access conditions — how equipment would reach the wall location, including side yard width, gate clearance, slope steepness, and distance from the street
- Material preferences — block, stone, concrete, or another material, though material selection is often driven by the wall's structural requirements as much as appearance
- Existing wall removal — whether an old wall needs to come out first, approximately how long and tall it is, and what it is built from
- Adjacent work — whether the retaining wall is part of a larger project such as a patio, driveway, grading correction, new construction, or drainage improvement
You do not need all of this before reaching out. A phone call or email with photos and a description of the wall situation is enough to start.
Cost and Schedule Factors
Retaining wall pricing depends on the actual site conditions, wall dimensions, material system, and project complexity — not a fixed formula. The main factors that move cost:
Wall height and length are the two most direct cost drivers. Taller walls require deeper footings, more material, more backfill, more compaction, and often reinforcement that shorter walls do not need. Longer walls multiply every material and labor line item across the full run.
Grade change and soil conditions affect excavation depth, drainage design, and backfill volume. Slopes with heavy clay soil retain water and require more aggressive drainage. Loose or unstable soil may require deeper or wider footings. The amount of earth being held back determines the lateral pressure the wall must resist.
Material system — segmental concrete block, natural stone, poured concrete, and masonry each carry different material, labor, and installation costs. Block systems are common for residential and landscape applications. Stone and poured concrete are often used for structural or architectural walls. The right material depends on the wall's function, the loads it carries, and the site conditions.
Drainage design is a cost factor on every retaining wall. Perforated pipe, gravel backfill, geotextile fabric, and surface drainage add material and labor. The drainage system is not optional — it is what keeps the wall from failing. Walls that skip or undersize drainage are the walls that lean, crack, and need to be replaced.
New installation versus replacement changes the total scope. Replacement projects include demolition and removal of the existing wall, disposal, and correction of whatever drainage, footing, or backfill problems caused the original failure — all before the new wall begins.
Decorative versus structural walls carry different material, reinforcement, and engineering requirements. A low landscape wall holding a garden bed is a different project than a wall supporting a driveway or parking area above it.
Engineering requirements apply in Utah when a retaining wall exceeds approximately four feet of retained height. Walls above that threshold generally require engineered design with stamped drawings from a licensed engineer as part of the permit application. Walls below four feet may still require permits depending on the city or county, proximity to buildings, or surcharge loads. Permitting in Utah is handled at the local level — each city and county has its own requirements and review process.
Access and equipment — tight side yards, steep slopes, and long distances from the street affect how excavation equipment, material, and backfill reach the wall. Limited access increases labor and may require different equipment or handling approaches.
Cornerstone provides free estimates. Project pricing is handled through a scope conversation, not a fixed menu. No price, deposit, or timeline commitment is made until the scope is reviewed and agreed on.
Process and Sequencing
Retaining wall construction follows a sequence. Each phase depends on the one before it, and skipping or misordering steps — especially drainage and compaction — is how walls fail early.
Scope and estimate — The project starts with a conversation about the site, the grade, the wall's purpose, and the role Cornerstone will fill. Photos, dimensions, and site conditions move this forward.
Site preparation and layout — The wall alignment, footing location, and drainage path are marked. Vegetation, surface material, and obstructions are cleared from the work zone.
Excavation — The base trench is dug to the required depth and width for the footing, accounting for frost depth, soil conditions, and the wall's height and load requirements. If an existing wall is being replaced, demolition and removal happen before excavation for the new wall begins.
Footing and base preparation — Compacted gravel is placed in the trench in lifts and compacted to create a stable, level bearing surface for the first course of wall material. The footing is what the entire wall rests on — if it settles, shifts, or washes out, the wall moves with it.
Drainage installation — Perforated drainage pipe is placed at the base of the wall behind the footing, surrounded by clean gravel and wrapped in geotextile fabric to prevent clogging. The drainage system collects groundwater that would otherwise build hydrostatic pressure behind the wall and redirects it to a discharge point away from the structure.
Wall construction — The wall is built from the base up, course by course. Each course is leveled, aligned, and connected according to the material system — interlocking connections for block, mortar for stone and masonry, formwork for poured concrete. Geogrid reinforcement layers are installed at specified heights and extended back into the soil for taller or higher-load walls.
Backfill and compaction — Clean granular backfill is placed behind the wall in lifts, not dumped all at once. Each lift is compacted mechanically before the next is added. Proper compaction prevents settlement, reduces lateral pressure, and keeps the drainage system in position.
Caps, finish, and grading — Cap blocks, capstones, or other finish elements are installed on top of the wall. The surrounding grade is shaped to direct surface water away from the wall face and toward the drainage system or off-site.
Responsibility boundaries: Cornerstone's role in coordinating or performing each phase depends on the project scope and requested role. Engineering design, surveying, permitting, inspection scheduling, and coordination with adjacent trades are discussed during the estimate — not assumed.

Exterior And Outdoor Services — The parent category for retaining wall services and all exterior construction, hardscape, and outdoor structural work.
Concrete Services — Flatwork, footings, foundations, and poured concrete structures. Concrete work frequently runs adjacent to retaining walls — patios, walkways, driveway slabs, and foundation walls that tie into or sit near retaining structures.
Masonry Services — Stone, block, brick, and mortar construction. Masonry materials and techniques overlap with certain retaining wall applications, particularly natural stone or mortared block walls.
Deck And Patio Services — Outdoor living spaces that often sit on or adjacent to retained grade. A patio at the top of a retaining wall depends on that wall to hold the ground beneath it.
Deck Services — Deck construction, repair, and replacement. Relevant when a deck structure connects to or spans over a retaining wall or retained slope.
Fence Services — Fences frequently run along the top of retaining walls or follow property lines where grade changes require wall and fence to work together structurally.
Asphalt And Paving Services — Driveways, parking areas, and paved surfaces that may sit above or adjacent to retaining walls, adding surcharge loads the wall must be designed to support.
Gutter Services — Gutter and downspout systems control roof runoff. Where downspouts discharge near a retaining wall, the added water affects drainage design and the pressure the wall experiences.
Irrigation And Sprinkler Services — Irrigation lines that run through or near retaining wall zones. Leaks or overspray can saturate backfill and increase hydrostatic pressure behind the wall over time.
Chimney And Fireplace Services — Chimney and fireplace construction, repair, and restoration. Connects when outdoor fireplace features are built into or positioned adjacent to retaining walls or retained slopes.

Frequently Asked Questions
Why do retaining walls fail even when the face still looks fine?
Because most retaining wall failures start behind the wall, not on the visible face. Drainage problems, saturated backfill, weak or missing footings, and added loads above the wall create pressure that builds gradually. The face may still look intact while the structure behind it is losing the ability to resist lateral forces. Common early signs include a slight forward lean at the top, horizontal cracking along courses, soil loss at the base, and water seeping through or pooling under the wall. By the time the face visibly gives way, the failure behind the wall has usually been progressing for months or years.
What usually affects retaining wall cost the most?
Wall height, wall length, and what the wall has to hold back. Taller walls need deeper footings, more material, more backfill and compaction, and often geogrid reinforcement and engineered design that shorter walls do not require. Length multiplies every material and labor cost across the full run. Beyond dimensions, the main factors are the material system (block, stone, poured concrete), drainage complexity, whether an existing wall needs to be demolished and removed first, equipment access, and whether the wall carries surcharge loads from a driveway, building, or parking area above it. Replacement projects carry additional cost because they include demolition, disposal, and correction of the conditions that caused the original failure.
When does a retaining wall need engineering in Utah?
As a general guideline, retaining walls exceeding approximately four feet of retained height require engineered design with stamped drawings from a licensed engineer. However, permitting in Utah is local — each city and county sets its own requirements and review thresholds. Walls under four feet may still trigger permit or engineering requirements depending on the jurisdiction, proximity to buildings or property lines, surcharge loads above the wall, or challenging soil conditions. The specific requirements for your project depend on where it is located, and those details are confirmed during the planning and estimate process.
What is the difference between a landscape wall and a structural retaining wall?
A landscape wall typically holds back a modest grade change — often under three to four feet — to create planting tiers, garden borders, or low transitions in the yard. A structural retaining wall holds back greater elevation changes and often supports loads from above, such as driveways, parking surfaces, stairs, or adjacent buildings. Structural walls require deeper footings, heavier reinforcement, more aggressive drainage, and frequently stamped engineering drawings. The distinction is not always obvious from the surface. It depends on the wall's height, the grade change, and what sits above and around the wall — not just the wall's appearance.
What should I check on an existing retaining wall before calling for an estimate?
Look for visible signs of movement or failure: forward lean at the top, cracking along mortar joints or block courses, bulging or bowing in the middle of the face, soil loss or erosion at the base, water seeping through the wall or pooling behind it, and material separation at corners or step transitions. Note the approximate height and length, what material the wall is built from, what sits above the wall, and how long the problems have been visible. Photos from multiple angles showing the face, top, base, and any damage are the most useful starting point when reaching out.
