Trenchless Technology for a Bursting Pipe
Trenchless technology for a bursting pipe is ideal for all of your trenchless sewer needs that will arise in your property. Pipe Bursting unique method of first inserting a steel cable in your existing sewer line than placing a bullet head to expand and break the old pipe makes it convenient and effective against any sewer line that over the years has lots of offsets and root intrusion inside the pipe. As the new pipe is being placed in the existing space, it will fix all the offsets and all the roots will be on the outside area of the new pipe. The new pipe will fuse, therefore you will not have to ever worry about offsets and root intrusions. Freedom does trenchless technology for pipe repair in San Jose, Sunnyvale, Los Altos, Mountain View, Santa Clara, Los Gatos, Saratoga, and Palo Alto.
Directional Drilling is designed to install all kinds of sizes of electrical conduits, sewer lines, water lines, gas lines and irrigation lines. Directional Drilling is designed for short and long distance areas. This technology allows the customer to preserve all expensive landscape and any existing underground pipes in the area. Directional Drilling has the capability to locate and direct the utility any place and any depth required for your needs.
Pneumatic Boring is ideal for projects where customers have small areas to maneuver. Some landscape areas are so small that it only allows for a drill. The Piercing tool works with a compressor which allows it to move back and forth as desired to create a bore in the ground, hammering through rock and clay soil. The new pipe can be installed leaving the original old pipe in place. Freedom Underground brings small pipes such as water lines, conduit lines and irrigation lines for this great technology.
A resin-saturated felt tube made of polyester, fiberglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation). It is possible to invert the liner upstream (e.g. from the downstream access point) but this carries greater risk. It is possible to install a liner from the downstream access point, upstream to a blind end however this carried the highest risk of all the CIPP installation methods. Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional “dig and replace” pipe repair methods. The liner can be inverted using water or air pressure. The pressure required for inversion can be generated using pressure vessels, scaffolds or a “Chip unit”. Hot water, UV light, ambient cured or steam is used to cure the resin and form a tight-fitting, jointless and corrosion-resistant replacement pipe.
Service laterals are restored internally with robotically controlled cutting devices in the larger diameter pipe. Smaller diameters (100mm)can be opened remotely however they are often reinstated by excavation. These can be sealed with additional seals into the lateral connection (Lateral Junction Repair)or T-Liner. The resin used is typically Polyester. Since all resins shrink and it is impossible to bond to a sewer that has Fats, Oils, and Grease an annular space exists between the new CIPP liner and the host pipe. The annular space exists in all installations just some are larger than others. The most effective way to prevent water from tracking in the annular space and entering back into the waste stream is through gasket sealing technology. Gaskets made from water swelling material (hydrophilic) can be placed at the ends of the host pipe and at the lateral connections. ASTM F2561 is the current industry standard for main to lateral connection lining by cured in place method. The rehabilitated pipe is then inspected by closed-circuit television (CCTV). CIPP is considered a trenchless technology.
