Trenchless slip-lining has been well-established (since the 1940s) as the most cost-effective method for extensive and large pipeline rehabilitations. The slip-lining process is just as it sounds – a smaller carrier pipe is slipped into a larger host pipe. Then, the negative space between the carrier and host pipe is filled and sealed with grout for a secure and effective rehabilitation which restores the integrity of the host pipe. The benefits of slip lining appear in the form of the following:
- Reduced time
- Reduced costs
- Minimal disruption; and
- Improved flow rates
Restoring structural stability is crucial in preserving the longevity and promoting cost savings in maintenance and repair while protecting against corrosion. Several materials can be used for carrier pipes in nearly every size. Common materials are
- High-density polyethylene (HDPE)
- Fiberglass-reinforced (FRP) and PVC
Slip lining can be installed continuously or segmented depending on the project’s material, design, and scope. Slip lining is a simple but effective old-school technique that is as applicable today as ever. Slip lining is commonly used for water, gas, and sewer mains.
Standard Pipe Services determines if slip lining is the right solution by assessing the problem with an internal CCTV inspection. This diagnostic identifies problem areas, types, and diameters of the host. Cleaning is sometimes required for a meaningful diagnostic. Slip-lining requires exact measurements to engineer ideal fixes.
Excavation
Slip-lining is semi-trenchless. The focus remains on minimal disruption, with maximum results; however, some excavation is necessary in large-diameter slip-lining solutions. Standard Pipe Services are experts in strategic excavation to access pipe insertion points.
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.
