Trenchless methods
Trenchless sewer repair in Denver: the no-dig options side by side
Trenchless is not one method but three, and a Denver lateral in heaving clay can call for any of them. This page sets lining, bursting and sectional repair against the failures found under Front Range yards so the proposal you receive makes sense.

Three methods, one question
The question behind every trenchless proposal is the same: how much of the old pipe can still do a job. Cured-in-place lining asks the old pipe to act as a form, so it needs a lateral that holds its round shape and its grade even if every joint leaks. Pipe bursting asks the old pipe only to show the way, so it tolerates collapse and deformation and even allows the new line to be a size larger. Sectional point repair asks the old pipe to be sound everywhere but one spot. In Denver, where a single lateral can be clay tile in the yard, Orangeburg at the property line and cast iron under the basement, the camera often finds reasons for more than one of these on the same run.
What the Front Range does to a lateral
Expansive bentonite clay underlies most of Denver and the rest of Denver County. It swells with spring snowmelt and summer cloudbursts, shrinks in the long dry spells, and freezes to roughly three feet in winter. A rigid pipe laid in three-foot sections cannot follow that movement, so joints open, sections tilt and a stretch sinks into a belly. Roots from elms, cottonwoods and silver maples find the open joints within a few seasons. The result is a lateral that leaks, catches paper on every offset, and finally blocks at the lowest point. The pattern decides the method: leaking joints and roots in a round pipe point to a liner; a collapsed or ovaled section points to bursting; one dropped joint points to a sleeve; a belly points to a short dig no matter what.
Lining in brief
After jetting and a camera run, a felt or fiberglass tube saturated with resin is inverted or winched through the lateral from a cleanout or a single pit, pressed against the host pipe with air or water, and cured with hot water, steam or UV light. The finished liner is a continuous pipe with no joints, rated for a design life of about fifty years, and a residential run in Denver is normally installed and cured in one working day. Branches are reopened from inside with a cutter. Lining is the most common trenchless repair in Denver County because it fits the most common failure here: roots and open joints in clay that is otherwise intact.
Bursting in brief
Bursting replaces rather than renews. A pit is dug at each end of the run, a cable is threaded through the old pipe, and a bursting head pulled behind it splits the host pipe outward while towing a fused HDPE pipe into the cavity. It handles Orangeburg that has gone oval, clay that has collapsed, and four-inch lines that need to become six-inch lines. The cost is two pits and the need to know what else lies along the alignment, since the bursting head displaces soil and can disturb a gas or water service lying tight against the sewer.
Point repair in brief
When the footage shows one offset, one crack or one root-filled joint on a line that is otherwise clean, a short sleeve two to six feet long is positioned over the defect on a packer and cured in place. It is the least disruptive of the three and the easiest to misuse: a sleeve on a pipe with five more bad joints is a repeat visit waiting to happen. Used correctly it is the right answer for a single bad spot under a slab or a driveway where nothing else is wrong.
What the proposal for a Denver lateral should contain
A trenchless proposal for a Denver lateral is only as good as the inspection behind it, so expect to receive the full video with footages, a locate sketch showing depth and position of each defect, and a scope that names the method for each segment and the length covered. It should name the permits the crew will pull, including the right-of-way permit if a pit or tie-in sits on public ground, and the restoration terms for any pit. It should include a written warranty naming the method, the length and the term, and a post-repair video.

Questions we hear about trenchless sewer repair
Is trenchless always cheaper than digging?+
Not always, but in Denver it usually is once restoration is counted. A short, shallow dig in open lawn can cost less than a liner. A dig under a driveway, a mature tree, a sidewalk or a street almost never does, because concrete, asphalt, traffic control and the right-of-way permit are paid for on top of the pipe.
How long is the sewer out of service?+
For a lining job, from the time the liner goes in until the cure finishes, typically several hours in a single working day. A burst takes a day for a residential lateral. A sectional sleeve is a few hours. The crew tells you the window in advance so the household plans around it.
Can trenchless methods reach the connection at the main under the street?+
Yes. That is the central advantage along the Front Range, where the owner is responsible all the way to the main. A liner is pushed or pulled to the tap and finished there; a burst pipe is pulled to a pit at the connection. The crew still pulls the right-of-way permit for any pit or tie-in on public ground.
Does a trenchless repair need a permit in Denver County?+
Lateral repairs are permitted work in most jurisdictions in Denver County, and inspectors are accustomed to lining and bursting. The contractor pulls the permit, schedules the inspection, and provides the post-repair video. Skipping the permit leaves you with an undocumented repair that a future buyer's inspector will question.
What if the camera shows a problem trenchless cannot fix?+
Then the proposal should say so and show you the footage that proves it, usually a belly or a collapse where the pipe has lost its grade. The honest answer is a short excavation of that section combined with a trenchless repair of the rest, not a liner that hides the problem for a season. Estimates are free; call now.
