Get a new sewerline without the mess, and for less!
When a sewer pipe is old and needs to be replaced, then traditionally
the shovels and excavation equipment come out and huge piles of dirt,
broken concrete, dust, debris and busted pipes are strewn about in a huge mess! Most dwellings that have pipes
older than 50 years are subject to replacement due to poor quality
building materials used in times of past. Likewise if a home is 50 years
old or older the landscaping is normally well established. So digging up the yard, breaking up the driveway, cutting through the sprinklers just does not make for a good situation.
Fortunately US Trenchless can rehabilitate your sewer line with no excavation!
about 18 years ago some pretty smart engineers developed a machine
that could replace all those failing pipes with out digging a trench,
hence the trenchless name. It has been a slow process, but little by
little people are reaping the benefits of this method. By not digging a
trench the destruction is limited to two small holes virtually
eliminating the mess, time burden and cost. The best news is that the
material used during the replacement carries a lifetime warranty, is
tough, flexible and because there are no seems or joints in the
pipeline roots can no longer grow into the pipe!
US Trenchless is proud to offer trenchless sewerline replacement using the pipe bursting method. A few of the benefits include:
- Size for size replacements (Same 4\" inside diameter)
- Can upsize pipes without digging
- Reduced cost
- Reduced time
- Reduced mess
- Saves landscaping
- Replace pipes under buildings and structures
- Lifetime warranty
- Complies with earthquake and ground movement (pipe is semi-flexible)
Read on to learn about our process of Pipe Bursting:
First we locate the old pipe and inspect the interior using a small camera attached to a long reel. We send this camera down the pipe and using a remote display screen we can qualify the condition, location, direction and depth of the pipe. Next using a hand held device we electronically locate the beginning and end of the pipeline length and mark them with paint on the surface. We excavate the two small areas (approx 4' x 4' each) and cut away the old pipe in the excavations. We feed a high strength steel cable through the old pipe from excavation to excavation; attach a small aluminum pulley mounted on a flat horizontal plate on one end. On top of the pulley we attach a hydraulic cylinder device that grabs the steel cable and pulls/ winches it through the old pipe at a power level equal 20,000lbs. On the other end is the new pipe connected to the steel cable that has a steel cone with a knife edge. The new pipe is semi flexible and the best part is that it has now joints. The new pipe is thermally welded (melted) together producing one monolithic pipeline, eliminated the chance for root intrusion for the life of the pipe; 100 years. The new pipe is connected to the steel splitting cone and hooked to the steel cable then pulled/ winched through the old pipe all the way to the other end of the pipe run where the aluminum pulley and hydraulic machine is located. One it get there we cut the steel splitting cone off the new pie and reconnect it to the existing upstream and downstream pipes in the respective excavations. The two holes are backfilled with soil and the pipe installation is complete.
