Prior to the creation of non-invasive sewer replacement equipment, professionals had to dig out deep trenches to access lines in need of service. The trenches often went straight through well manicured lawns and garden beds that owners worked hard to maintain. Sewer lines running beneath established sheds, garages and additions posed an even bigger problem for homeowners looking for a quick fix. Luckily, there are a number of ways to perform simple repairs or replacements of broken pipes. Read on to learn more information.
Despite the use of tough pipe materials for sewer pipes, including reinforced concrete, steel and ceramic, corrosive elements slowly break down the structure until a breach occurs. When a pipe develops a hole, crack or full break, waste products in their solid, liquid and gas forms leak out into the soil. Many homeowners initially notice the smell until enough waste leaks through, saturating the soil and bringing full attention to the location of the problem pipes.
Sewer professionals will often recommend having the pipe lined from afar if the breach is contained to a specific area. To confirm the need for a pipe liner, technicians inspect the lines using camera equipment. After cleaning the pipes, sewer techs create the liner by injecting the broken pipe with felt coated in strong epoxy resin. An air filled bladder inflates the soaked felt to fit the inside diameter of the pipe until it cures. Once the liner cures, techs deflate the bladder and perform a final inspection to confirm the patch fixed the breakage.
Pipes that have completely collapsed at various spots throughout the line cannot support the use of patching materials. Instead, sewer line replacement technicians must install a brand new pipe in that location. Normally, techs would dig out a trench around the line to access the entire stretch of pipe in one repair session.
Luckily, a ground piercing mechanism was developed to quickly break up the rest of the pipe and create an installation hole at the same time. Technicians place the piercing end at the beginning or end of the pipe to start. Using a large sledgehammer, techs ram the piercer through the ground at the specified pipe location. Once the reamer creates the hole, techs thread a new pipe through the soil and attach it to the connection joints at either end. As a manually driven tool, the ground piercer can only handle sewer line replacement below modest garden beds or patios.
Since the ground piercing equipment can only work through a limited amount of ground, larger jobs require the use of hydraulically driven directional boring equipment. The directional boring machines have no limit in pipe size or diameter due to the various heads technicians can use for the job. By breaking up the pipe and creating an access hole, the machinery essentially performs the same task as the ground piercing equipment at a larger scale. The directional boring machine uses an exact targeting system that makes it easy to establish brand new pipes for additions and new construction when needed.
Exploring The Main Benefit Of Trenchless Replacement
The main benefit of choosing trenchless repair practices is cost. Even extremely large scale city projects see a 25% decrease in costs when using trenchless sewer repair or replacement techniques. After all, digging a trench requires use of expensive heavy equipment, including full size backhoes. The equipment used to perform the trenchless repairs costs a lot less to transport and use. Furthermore, the repairs take much less time than a full trench dig, so the labor costs do not add up as quickly either.
Cost also surrounds the amount of building and yard repairs required after digging out a large trench. Even reseeding the lawn or replacing plants in the garden can take a significant amount of time and money. Rebuilding an entire garage, shed or addition can definitely rocket the job far out of the given budget range. With trenchless repairs, you keep costs low and benefit from the convenience of obtaining a quick, effective sewer line repair or replacement.
