A Trenchless Water Main Replacement System is a process that allows the replacement of existing pipe without having to dig a trench, and therefore will not have an impact on your homes landscaping, including patios, decks, walkways, or driveways. The pipe used in the trenchless system is made of a strong polyethylene that is virtually root and chemical proof. It has a life expectancy of well over 100 years, and is quickly becoming the standard in all underground piping installations.
The piping is seamed to fit on the job site, and is pulled into place underground using trenchless technology. Plus the benefits to you as a homeowner are many:
1. Quick Installation – a normal project can easily be completed in just a day.
2. Cost Effective – replace the broken or backed up pipe instead of having to replace landscaping too.
3. Strong – because of its strong construction and seamless design, it’s a great way to guard against future problems.
With a trenchless system, the old pipe is located and prepped for replacement. Both ends – the beginning and ending pipe or the problem area – are found and cut. The polyethylene pipe is laid out and seamed together to create the correct length. A cable is used to snake through the pipe, and lead the new pipe through the existing pipe, breaking away the old. As a trained technician, we will ensure the entire process occurs smoothly, and corrects the original problem.
Just because your sewer line is underground doesn't mean that the issue has to remain hidden from view. Sewer line cameras are inserted into the line by a nearby cleanout and allow our Technicians to inspect your line from beginning-point to end-point in order to see any issues and the stage of the problem. Locator heads then allow technicians to accurately pinpoint any problem areas underground and even identify if the issue is your responsibility or a city/county issue. Why pay for over-kill fixes when you can get right-fit options based on a visual diagnosis.
Benefits of Video Sewer Inspections
1. No guesswork. Avoid overkill solutions and unnecessary digging based on guesswork.
2. Included for free with every sewer replacement.
3. Pinpoint problems underground. Don't pay for repairs that aren't your responsibility.
4. Low cost pipe locating method.
5. See the issues as we make recommendations.
How Does Video Sewer Inspection Work?
1. Sewer Line Accessed The sewer line is accessed through a nearby cleanout. Once the line is visually inspected for standing water or backups that would impede visibility, the camera is inserted into the line.
2. Two Direction Inspection Technicians advance the camera along the line as you watch along, noting any problems so that you can see what they see. The line is inspected both from the cleanout to the main sewer and also back into the home to ensure a proper diagnosis.
3. Suspect Areas Located Areas of potential issue are then located above ground to identify where they are on the property and assess the surrounding area. Using this information, or technicians are able to give a highly accurate diagnosis that you can see for yourself, identify the stage of the problem and give a prognosis. Once this is done, right-fit options are outlined to meet with your time and budgetary needs.
Directional drilling is a trenchless method of underground pipe installation. Horizontal boring machines drill a pilot hole, which is able to enter and exit at predetermined locations and even change direction to avoid underground obstructions and preexisting lines. From this pilot hole, a new sewer or water line can be established without a preexisting line - allowing for completely underground installation without the mess or expense of trenching!
Benefits of Directional Drilling
1. Avoid damage to your home, landscaping and hardscaping.
2. Trenchless option for establishing a new line.
3. Significant cost savings compared to conventional line installation methods.
4. Shorter completion times & safer for the environment.
1. Establish A Pilot Hole After the site has been prepped, a horizontal boring machine (about the size of a golf cart) is moved into place and a bore head is connected to hollow pipe, which enters the ground at an angle. As the bore head drills a pilot hole, additional pipe sections are added until the pilot hole is complete.
2. Pilot Hole Enlarged For New Line After the boring head exists at a predetermined location at the other side of the run, a reamer is attached. Once attached, the reamer is pulled back through the line clearing soil and even rocks to expand the hole to a size that is 25% larger than the pipe that is to be inserted.
3. New Line Established Once the hole has been prepared, a new line is pulled through the opening created. Once successfully in place the ends of the line are connected and the project is complete.
While other companies may start with conventional methods for sewer pipe replacement – A&A Construction and Utilities, Inc only considers conventional methods for situations when trenchless methods can't be applied, or the rare circumstance that conventional methods are more cost effective for our customers.
Can be applied in circumstances where Trenchless methods cannot be used.
Excavation To Expose Old Line Excavation equipment or a hand digging team is brought in to dig up the line that needs to be replaced, following from where it leaves the foundation out to the end of the run. An area such as patios, foundations, walkways, and landscaping is demolished along the way to provide access to the pipe below ground.
New Line Installed After the old line has been exposed and removed; a new line is placed into the trench created to remove the old line. The line is checked to ensure proper grade and alignment and then re-connected on either end.
Excavated Materials Put Back After the new line is in place, the excavated material is put back into place and the trenches refilled. As much landscaping elements as possible will be restored, but many times additional contractors are needed.
DON’T dig up your yard, landscaping and harddscaping. Pipe bursting is a trenchless sewer replacement method where a large cone shape head is hydraulically pulled by steel cable through the old sewer line, breaking apart the old pipe underground while at the same time pulling into place a seamless HDPE pipe that is the same size.
1. Identify the Problem by Sewer Camera When we come to your home we will run a camera through your sewer main lines and/or kitchen/laundry lateral lines. From here the technician will be able to evaluate your needs and recommend the best solution trenchless sewer repair for your specific problem.
2. Access The Sewer Line Two small holes are dug at either end of the sewer run that will be replaced. Cable is inserted at one end and fed through. One end of the cable is attached to a pneumatic jack while the other end is attached to a cone shaped bursting head.
3. New Pipe Inserted In Place Of Old Pipe The bursting head is attached to a new seamless, heat-fused HDPE pipe. As the bursting head is pulled through the old sewer line, it simultaneously breaks apart the old pipe (even cast iron) and pulls behind the new pipe.
