Full-Length Relining is performed using Cured-in-Place (CIPP) [link to Short CIPP service page] methods with Polyurethane, Polypropylene, Fiberglass materials, or Cementitious materials. Trenchless CIPP is a popular method to repair short and long runs of pipe that do not require upsizing. Standard Pipe Services (SPS) has an exceptional resume of success in performing full-length lining and various repair types for every situation. The process starts by cleaning the sections to diagnose sharp edges, giant gaping holes, or other defects to ensure lining material is not affected by the pipe defects.
SPS provides high-quality full-length relining across several states and understands the unique problems of each environment. To date, we have installed over ONE MILLION LF of lining material establishing Standard Pipe Services as the experienced leader in the field and the standard setter in the industry for quality and accountability. Our reputation proceeds us in finding solutions to complex projects that other companies have turned down. Our knowledge and experience are reflected in our work and installation process.
Installation
Standard Pipe Services begins with resin-saturated lining tubes installed in a line section by winching or inversion. Once in place, heat is introduced to induce the chemical catalyst, or hardener, to initiate the curing process. The curing process is performed by steam or hot water. The specific situation dictates what type of curing method SPS recommends. Full-Length Lining techniques are used to renovate:
- Gravity line sections
- Culverts
- Water lines
- Gas lines; or
- Pressure pipes
The length of the relining is situationally dependent, but it can go through several manholes or catch basins.
Lining Preparation
All line sections must be prepared before the installation process. Standard Pipe Services will clean the line section using a jetter nozzle [link back to cleaning page] with high-pressure water to remove debris or other materials from the line section and cut any protruding elements. Removing as much debris as possible is essential to create a smooth surface for the relining material. SPS will evaluate if additional repair work is required before relining. Further repair work may include installing a short cured-in-place point repair, or grouting laterals and joints.
Performing the Relining Process
The lining material is a non-woven polyester needle felt or glass fiber. For pressure pipes, woven products are common to ensure maximum durability to withstand the internal pressures within the pipeline. A coating made from PU, PE, or PVC protects the liner during transportation and installation procedures. Standard Pipe Services works with multiple manufacturers that prepare the liner with:
- Polyester
- Vinyl ester
- Epoxy; or
- Polypropylene
Once the lining material is designed, it is shipped to the job site in a refrigerated vehicle to ensure that the curing is not triggered prematurely. Lining material has a shelf life of 2 to 3 weeks. On delivery, the lining material is either pulled or winched into place and inflated with steam or water by inversion. The job dictates the amount of pressure applied. Proper care is taken to avoid stretching or wrinkling of the liner. After placing the liner, the boiler will cure the material. Boilers vary from small 90kw to large 3 million BTU, depending on the volume of water to be heated. Curing temperatures differentiate depending on the resin used. If SPS is performing the relining with steam, we will utilize a stronger lining material than one that is cured with hot water.
After the lining material cures, a slow-pressure cooling process begins to avoid unnecessary stretching or shrinking of the material. At this point, laterals must be reinstated by cutting them out with a Schwalm cutting tool. The trimmings will be jetted and removed from the line section for safe disposal. If multiple laterals exist in the line section, SPS recommends grouting to reduce additional infiltration.

Lateral Reinstatement
Reestablishing lateral connections is essential after installing a cured-in-place pipe (CIPP) to restore piping systems to a functional condition. Reinstatement involves cutting an opening in the new pipe liner after it is cured. Lateral reinstatement must happen because, during CIPP installations, laterals are covered with lining and sealed, so the flow is halted. Specialty tools are used to ensure no damage to laterals or pipe integrity.
Standard Pipe Services (SPS) implements trenchless technology for all pipe rehabilitations. Pipe rehabilitation is the repairing or replacement of the underground network of sewer and water pipelines. To quote or blog on trenchless technology:
Trenchless Technology incorporates several pipe rehabilitation methods with little to no digging and is eco-friendly. It is, as it sounds, ‘trenchless’. Trenchless technologies offer quick, cost-effective solutions for repairing or replacing pipes and manholes while featuring non-disruptive strategies.
By cost-effective, trenchless doesn’t save pennies – it is about HALF the cost of digging up lines under the pavement or surface. Before trenchless technology, you would have to replace more of your sidewalk, driveway, decorative pavers, or cobblestone. Trenchless is a considerable money saving. Most trenchless repairs take one day and a few workers. But this is not every case. Contact us today to discuss how we can help you. You may also find helpful answers in our Blog or FAQ.
