Trenching in Austin is not straightforward digging. The combination of clay soils, caliche at shallow depth, and limestone formations in the central and western parts of the metro creates conditions that affect trench stability, equipment selection, and the time required to reach the specified depth. Contractors who do not work with Austin soil regularly underestimate how often caliche appears and what it does to a project when it comes up unexpectedly. Our operators encounter it weekly and have the equipment and experience to manage it without stopping the project.
Utility Trenching Services
We dig trenches for all types of utilities installed on residential and commercial properties in Austin. The scope and depth vary by utility, but the approach is consistent: 811 locate before any digging, correct depth and bedding per code, OSHA-compliant protection at qualifying depths, and clean backfill and compaction after the utility is placed.
Water Service Trenching
Water service lines in Austin typically run 18 to 24 inches deep. Residential water service trenches are straightforward where soil conditions cooperate and more involved when caliche sits at the required depth. We carry hydraulic breaking attachments and use them when rock is encountered, rather than forcing standard excavation equipment into conditions for which it is not designed.
Sewer Trenching
Sewer trench depth depends on the elevation at the connection point and the required fall to the main. Some Austin properties require deep sewer trenches due to grade changes across the lot. At depths of 5 feet or more, OSHA-compliant shoring or sloping is required. Our crews work to the shoring standards appropriate for the soil conditions at the specific site rather than applying a single approach regardless of what is in the ground.
Gas Line Trenching
Gas line trenching requires careful coordination with utility locates and specific bedding material requirements per code. We work alongside licensed plumbers and gas fitters on these projects and provide trenching, bedding, and backfill to their specifications.
Electrical Conduit Trenching
Electrical conduit runs for residential service upgrades, commercial power distribution, and exterior lighting are a regular part of our trenching scope. Depth and conduit type requirements vary by application, and we work from the electrical contractor’s layout to cut the trench to their specification.
Irrigation and Fiber Trenching
Irrigation system trenching and fiber conduit runs are typically shallower than utility trenching but require precision on grade and routing to follow the layout correctly. We handle these for residential and commercial properties, including HOA communities with tight access requirements.
Drainage Trenching
A significant portion of our trenching work is for drainage systems. French drain installation requires precise trench grade, correct gravel bedding, perforated pipe placement, and a functional outlet before the trench is backfilled. A French drain that drains to nowhere solves nothing — we assess the full drainage path from inlet to outlet before any digging begins.
We also trench for channel drains, catch basins, and perimeter foundation drains as part of our broader drainage contractor services. Drainage trench work requires closer attention to grade control than utility trenching, and we verify slope before backfilling to confirm the system will flow correctly.
Foundation Perimeter Trenching
Foundation perimeter trenching for drainage correctives and waterproofing systems is work we do on existing structures experiencing moisture or hydrostatic pressure issues. We trench around the foundation perimeter to the specified depth, prepare for the drainage system installation, and backfill and compact correctly to avoid adding settlement risk to the structure we are trying to protect.
On new construction, perimeter trenching for concrete slab foundations is part of the site prep sequence. We sequence the trench work with the grading and building pad prep so the foundation contractor receives a ready site rather than one that needs another trade to finish.
Trenching and Austin Terrain
Austin’s terrain poses three specific trenching challenges that contractors working here for the first time often underestimate.
Caliche is the most common complication. This calcium carbonate hardpan forms at varying depths across the metro and is harder than soil but softer than limestone. Standard bucket excavation cannot break through it. We carry hydraulic hammer attachments and switch to them when caliche appears rather than trying to force standard equipment through material it cannot cut.
Clay soil affects trench wall stability at depths where it is fully saturated. Austin clay holds its structure when dry but loses cohesion when wet. Trenching during or after heavy rain in clay-rich areas requires additional care to prevent wall sloughing, which can bury the pipe or create safety hazards.
Limestone bedrock in the central and western parts of the city can appear at depths that interfere with utility trenching. When rock must be broken at depth, the work takes longer and costs more than equivalent trenching in softer soil. We account for the terrain at the specific address when we estimate, not the city average.
811 and Utility Coordination
Texas law requires calling 811 at least two business days before any digging begins. This is not optional; it is legally required and protects everyone on the job site from striking an active gas, water, or electrical line. We require confirmation that 811 locates are complete before any trenching equipment arrives at a site.
For sites with private utilities, buried irrigation systems, secondary electrical runs, or other infrastructure not on the 811 database, we work with private locate services to mark additional lines before digging. Private utilities are responsible for a significant share of underground strikes on residential properties in Austin because homeowners often do not know where previous contractors buried lines.
OSHA Compliance in Trenching
Federal OSHA standards require protective systems for any excavation 5 feet or deeper in most soil types. For Type C soils, which include previously disturbed material and saturated soil common in Austin after rain, protective systems may be required at shallower depths. We use the classification that best fits the site’s actual soil conditions, not a generic standard.
Protective systems for qualifying-depth trenches include sloping to the required angle, hydraulic shoring, or trench boxes, depending on depth, soil type, and the duration the trench stays open. We do not cut corners on this because the consequences of a trench collapse are serious and irreversible.

Frequently Asked Questions
What trenching services does Ace Construction Texas provide?
Ace Construction Texas provides utility trenching for water, sewer, gas, electrical conduit, fiber, and irrigation lines, drainage trenching for French drains and surface drain systems, foundation perimeter trenching, and septic system trenching for residential and commercial projects throughout Austin, TX, and Central Texas.
Do you handle 811 utility locates before trenching?
Yes. We require 811 utility locates before any digging begins on every project. This is legally required in Texas and protects both our crew and existing infrastructure. For complex sites with private utilities that 811 does not locate, we work with private locate services to mark additional lines before equipment moves.
How deep can you trench in Austin TX?
Trench depth depends on the utility type and the engineer’s project specifications. Water service lines in Austin typically run 18 to 24 inches deep. Sewer lines run deeper based on the elevation at the connection point. Gas and electrical conduit depths follow code requirements for each utility type. When trenching encounters caliche or limestone at the required depth, we use hydraulic breaking equipment to reach the specified depth without compromising the grade.
How do you handle trenching in Austin's caliche and limestone?
Caliche and limestone are common in Austin at depths that affect utility trenching on many properties. When our trenching equipment encounters rock, we switch to hydraulic breaking attachments to break through it rather than forcing the equipment beyond its rating. Our operators have worked Austin soil for over 16 years and are experienced with the depth and distribution of caliche across the metro.
What is OSHA shoring compliance in trenching?
OSHA requires protective systems for any excavation 5 feet or deeper in most soil conditions. This includes sloping, shoring with timber or hydraulic struts, or trench boxes, depending on depth and soil type. All of our trenching work at qualifying depths follows federal OSHA standards for worker protection in excavations.
Can you trench for a French drain installation?
Yes. We handle the full scope of French drain trenching, including the excavation, gravel bedding, perforated pipe placement, and outlet connections. We also coordinate the trench grade and outlet location with our drainage crew. Hence, the installed system functions properly and drains to an appropriate outlet rather than simply moving water to another problem area.
How long does a residential trenching project take?
A standard residential utility trench in Austin typically takes one to two days, depending on the length, depth, soil conditions, and how much caliche or rock is encountered. Drainage trench projects that require careful grade control take longer than straightforward utility runs. We provide a project-specific timeline estimate during the site assessment before any work begins.
Is Ace Construction Texas insured for trenching work?
Yes. Ace Construction Texas carries full insurance on all trenching projects. We provide certificates of insurance to homeowners, plumbers, electricians, and general contractors before any work begins.
