Yazhi Engineering LLC is a geotechnical and retaining-structure practice working from its anchor yard at 7533 S Center View Ct, West Jordan - 84084-5526, United States (US). We design deadman anchor walls, soil nail and ground anchor systems, and the drainage that keeps them working. Every scheme we issue is built from field readings, soil strength parameters and load cases that we can defend in a review meeting.
A wall is a promise made by soil to steel and concrete. Our work is to prove that promise at the desk, at the trench and at the test stand before the backfill ever arrives.

Each service below is delivered by the same small team, using the same field book, the same load cases and the same review checklist. Nothing is handed off to a subcontractor whose methods we have not inspected. This is deliberate: an anchor wall fails as a single system, so it must be designed as one.
Cantilever, counterfort, gabion and deadman anchored walls are sized against the measured soil profile, not a table. We produce the wall elevation, the anchor schedule, the bearing check and the construction sequence, and we state plainly which assumptions carry the most risk. Yazhi Engineering LLC has designed walls on tight residential lots where the excavator had no room to swing, and those constraints are written into the drawing rather than discovered later.
Tieback, soil nail, helical and grouted anchor systems are specified with grout volume, bond length, lock-off load and corrosion protection spelled out. We model the failure surface, check pullout against the geotechnical report, and set a proof load that the contractor can actually reach with available equipment. Where the ground is too variable for a single bond length, we design a staged test program instead of guessing.
When a cut slope starts to creep, the answer is rarely more concrete at the toe. We read the movement, find the water, and design a stabilization scheme that combines regrading, subdrainage, anchored beams or soil nails as the geometry demands. Monitoring points are set before work begins so that the effect of each stage can be measured rather than assumed.
Existing footings carrying new loads are assessed with a real bearing check, an inspection of the as-built condition and a candid statement of what the record drawings omit. We report the settlement risk, the repair options and the monitoring plan in the same document so that a client can make a decision without a second round of consultants.
Water is the most common cause of wall distress we are called to inspect. Weep holes blocked by fines, a missing filter fabric and a downspout discharging at the wall face can each double the pressure a wall was designed for. We design the collector, the filter envelope, the outlet and the surface grading as one system, and we verify the outlet actually runs.
Proof testing turns a design claim into evidence. We witness or specify anchor proof and performance tests, review the load cell dial readings, and issue a signed report with the acceptance criteria, the deviations and the remedial steps where a test falls short. The report is written for a reviewer who was not on site, so every reading is traceable to a date, a location and an instrument.
A project with Yazhi Engineering LLC usually begins with a walk along the wall line, a look at the soil in the excavation and a short conversation about what the owner needs the ground to do. From there we assemble the design basis: the soil profile, the groundwater assumption, the surcharge the wall must carry and the movement tolerance that the structure above can accept. These four values drive everything that follows, and we write them down before any geometry is drawn.
Design then proceeds in two passes. The first pass checks stability with conservative parameters to see whether the concept is viable at all. The second pass refines anchor spacing, bond lengths and drainage details against the specific contractor methods and the actual access on site. We do not issue a drawing that cannot be built with the plant available in West Jordan and the surrounding valley, because a design that ignores access pressure ends up changed in the field without a check.
Construction support is where most of the value sits. We attend the proof tests, read the dials, and review the grout records. Where a test result sits close to the limit, we say so and recommend a specific action rather than a general caution. The final report gathers the design, the field records and the as-built deviations into one file that the owner can hand to a future inspector without a gap in the evidence chain.

Every design rests on what the soil will actually do. We read the report, ask what the logger saw, and where the record is thin we recommend a targeted investigation rather than a blanket conservative factor that inflates cost without adding safety.
A wall that needs a crane on a lot with no crane access is not a finished design. We check access, spoil space, concrete delivery and test equipment before the drawing leaves the office.
Proof test dials, grout volumes and movement readings are recorded and filed. When a future owner asks whether the anchors were tested, the answer is a dated page, not a memory.
Retaining walls sit in a strange place in construction. They are expensive enough to matter and common enough to be treated as routine, and that combination produces a large number of small failures. A wall that moves ten millimetres a year looks fine in the first season and distressed by the fifth. By the time the crack is visible, the repair usually involves temporary shoring, a new drainage system and an anchor program that costs more than the original wall.
Our practice exists to move that cost earlier. A wall designed with a proper drainage envelope, an anchor schedule matched to the tested bond capacity of the ground and a construction sequence that keeps the excavation supported does not need to be more expensive than a wall designed by habit. It is simply designed with the failure modes in view. The same is true of slopes: a creeping hillside is cheaper to arrest with drainage and anchors before the toe has been undercut for a new driveway.
We work with homeowners, general contractors, civil engineers and property managers. Each brings a different question. The homeowner wants to know whether the wall is safe and what the repair will cost. The contractor wants drawings that can be priced and built. The engineer wants the numbers to be auditable. The property manager wants a report that satisfies an insurer. Our documents try to answer all four at once, which is why they are longer than a typical one page memo and shorter than a research paper.
A note on geography: the soils in the valley around West Jordan vary sharply over short distances, from stiff clay to gravelly alluvium and weathered bedrock. An anchor that holds perfectly on one lot may pull out on the next. We treat each site as its own investigation, and we resist the temptation to reuse a design that worked nearby. The anchor yard at 7533 S Center View Ct, West Jordan - 84084-5526, United States (US) stores our test equipment and handles intake for new projects, and the doorstep walk from that yard to a client site is usually short enough to visit twice.
If you are at the early stage, before a wall is drawn and before a contractor is hired, that is the cheapest moment to involve an engineer. If you are at the late stage, with a crack widening and a tenant asking questions, we can still help, but the conversation will be about stabilization first and aesthetics later. Either way, the first step is a site walk, and we keep that step short.
