Spiral Wound Pipe Lining

What Spiral Wound Pipe Lining does

SEKISUI SPR Americas, LLC, operating under the historical name Spiral Wound Pipe Lining, is a U.S.-based trenchless pipe rehabilitation technology company headquartered in Austell, Georgia, and a wholly-owned subsidiary of Japanese conglomerate SEKISUI Chemical Co., Ltd. Founded in 2005 as the Americas regional entity for technology that originated in Australia and Japan in the 1980s, the company develops and licenses Spiral Wound lining methods — mechanically winding continuous PVC strip profiles inside existing deteriorated pipelines to form structural liners without excavation. Its product portfolio comprises three trademarked methods covering 6" to 200"+ diameter pipes: SPR™EX (tight-fit expanding liner for 6"-42" gravity pipelines, installed without annular space grouting), SPR™TF (tight-fit traversing method for 40"-60"), and SPR™ (fully structural liner for 32"-200"+ round and non-round shapes, requiring grouting with steel reinforcement). The technology is codified into ASTM F1697-18 and ASTM 1741-18 standards and is approved by NASSCO.

The company operates a licensing-and-supply business model rather than direct project execution. Revenue is generated by licensing Spiral Wound technology and selling proprietary winding equipment and PVC profile materials to a certified installer network of contractors across the U.S., including Ruby-Collins Inc., SAK Construction, Nu-Line Technologies, Southwest Pipeline & Trenchless Corp., AUI Inc., and James W. Fowler Co. SEKISUI SPR supports installers with web-based and field training and technical consultation, and works directly with municipalities during project design to recommend methods and specifications. End customers are U.S. municipal, county, state, and federal government agencies responsible for sewer, storm drain, and culvert infrastructure, with named relationships including the City of San Diego (1M+ LF of SPR™EX installed), LA County Department of Public Works (750,000+ LF), the City of Atlanta, the City of Portland, Kansas City Water Services, Caltrans, and Joint Base Charleston. The technology addresses sanitary sewer overflows, EPA Consent Decree compliance, H2S corrosion, and aging infrastructure through a chemical-free mechanical process that can be installed in live flow conditions (up to 25-30% low velocity flow), eliminating bypass pumping costs of 15-20% of project bids. Cumulative installations exceed 4 million linear feet in the U.S. and 20 million linear feet worldwide.

Core offering

SEKISUI SPR Americas licenses and supplies its proprietary Spiral Wound pipe lining technology for trenchless rehabilitation of gravity sewers, storm drains, and culverts without excavation. The portfolio includes three methods (SPR™EX, SPR™TF/RO, SPR™) covering pipe diameters from 6" to 200"+ and is delivered to a nationwide network of certified installers along with PVC profile materials, winding equipment, training, and ongoing technical support.

Product overview

SEKISUI SPR Americas offers three main spiral wound pipe lining products/methods: SPR™EX (6"-42", groutless expanding tight-fit), SPR™TF (40"-60", groutless tight-fit against pipe wall), and SPR™ (32"-200"+, grouted solution for round and non-round pipes). All methods use mechanically wound continuous PVC strip to form uniform liners inside existing deteriorated pipelines without digging. The portfolio ranges from smaller diameter sewer rehabilitation to large diameter culvert and storm drain applications, with different methods suited for different diameter ranges and site conditions.

Products and services

• SPR™EX Tight-fitting expanding liner for 6" to 42" gravity pipelines. Uses a double-locking mechanism with primary and secondary locks; upon installation, the PVC liner is expanded directly against the host pipe wall, requiring no annular space grouting. Can be installed in live flow conditions up to 25-30% low-velocity flow. Sold to certified installers and specified for municipal sewer, storm drain, and culvert rehabilitation projects.
• SPR™TF/RO Tight-fitting winding method for 40" to 60" gravity pipelines. A traversing machine with hydraulically powered arms lines PVC directly against the host pipe wall, requiring no expansion process and no annular space grouting. Sold to certified installers for mid-diameter municipal sewer and storm drain rehabilitation.
• SPR™ Fully structural PVC liner for 32" to 200"+ large-diameter pipe rehabilitation, including round and non-round shapes. Uses a traversing winding machine that travels the pipe segment while constructing the liner. Requires annular space grouting with steel reinforcement. Sold to certified installers for large-diameter sewer, storm drain, and culvert rehabilitation.

Scale indicators6 records

Recent moves4 records

Expansion highlights5 records

Broad incumbents

• Aegion Corporation (parent of Insituform): Aegion owns Insituform, the leading CIPP technology and installer in the U.S. Aegion competes head-to-head with SEKISUI SPR for municipal sewer rehabilitation bids, but at much greater scale (Insituform alone has installed far more linear feet than SPR). Comparable because it sells both the liner technology and the installation services through a licensed/affiliated contractor model — the same architecture SEKISUI SPR uses for spiral wound.
• Per Aarsleff A/S: Danish trenchless technology specialist that licenses and installs the NoDig/NoPox CIPP liner systems for sewer and pressure pipe rehabilitation across Europe and increasingly in North America. Comparable to SEKISUI SPR as a trenchless technology licensor with global reach and a strong municipal/infrastructure customer base.
• Trelleborg Pipe Liners: Trelleborg manufactures flexible pipe relining products including the epros CIPP systems used in drain, sewer, and pressure pipe rehabilitation. As a large industrial conglomerate, Trelleborg sits adjacent to SEKISUI Chemical — both are diversified parents that fund infrastructure-technology business units, with comparable municipal trenchless technology offerings.
• Mueller Water Products: Large U.S. supplier of water and wastewater infrastructure products — pipe, valves, hydrants, metering, and pipe rehabilitation solutions through its Critchley Miller brand and Echologics asset-management services. Comparable to SEKISUI SPR as a supplier into municipal water/wastewater markets, though focused on new-build fittings and condition assessment rather than trenchless rehabilitation.

Direct peers

• HammerHead Trenchless: Manufacturer of trenchless equipment for pipe replacement and rehabilitation including static-burst, pneumatic, and lateral-lining systems. Comparable to SEKISUI SPR as an equipment-and-materials vendor with a dealer/installer network serving U.S. municipal contractors, though their technology stack (pipe bursting, CIPP) differs from spiral wound.
• Insituform Technologies: The dominant CIPP (cured-in-place pipe) technology licensor and installer for gravity and pressure sewer rehabilitation. Insituform is the principal trenchless competitor SEKISUI SPR faces on U.S. municipal bids, using a similar technology-licensing-plus-installer-network business model but with a fundamentally different installation chemistry (CIPP resin vs. mechanical PVC winding).
• iMPREG GmbH: German manufacturer of glass-fiber-reinforced plastic (GRP) UV-cured trenchless liner systems for gravity and pressure sewer rehabilitation. Sells equipment, liners, and licensing to installers globally. Comparable to SEKISUI SPR as a non-CIPP trenchless technology licensor with international reach and a chemical/UV-cured alternative to spiral wound.
• LMK Technologies: Manufacturer of CIPP liners, mainline/lateral connection systems, and spot-repair equipment for trenchless sewer rehabilitation. LMK sells equipment and materials to a network of certified installers, mirroring SEKISUI SPR's channel model. Direct competitor on the 6″–48″ gravity sewer rehab range that overlaps heavily with SPR™EX.
• National Liner: Manufacturer of CIPP liners and calibration hoses used in the CIPP installation process. Comparable to SEKISUI SPR as a materials/equipment supplier selling to a network of municipal rehabilitation contractors. Competes in the small-to-medium diameter gravity sewer rehab market.

Others

• SAK Construction: National U.S. contractor (and licensed Spiral Wound installer) that rehabilitates large-diameter sanitary sewers, storm drains, and tunnels via tunneling and trenchless methods. Comparable because SAK is both an installer-partner of SEKISUI SPR and a multi-method competitor bidding the same municipal projects. Listed as a current SEKISUI SPR licensee (Kansas City 114″ brick project).
