PREDL

What PREDL does

PREDL GmbH, founded in 1992 by Manfred Predl in Bönitz (South Brandenburg, Germany), is a specialty industrial manufacturer of plastic manhole infrastructure components used in municipal wastewater and stormwater systems. The company produces manhole base liners in polypropylene (PP) and glass-fiber reinforced plastic (GRP/GFK), the CORPROTECT lining system for manhole rings and cones, the PMA-Liner fully lined system, the FLEXLINER trenchless polyurea rehabilitation system supported by 3D laser scanning, and the DUPLEX-Schacht complete plastic manhole system. Manufacturing is concentrated at the Bönitz headquarters and the PREDL Austria facility in Fernitz, with on-site photovoltaic generation of approximately 821,000 kWh per year.

PREDL serves three primary customer segments: municipal utilities and public works authorities managing wastewater and stormwater infrastructure; sewer rehabilitation contractors executing trenchless and manhole-in-manhole projects; and precast concrete manufacturers participating in the Premium Producer quality certification program, who integrate PREDL base liners into their finished manhole products. The company also operates an international franchise model in which partners purchase manhole base kits and assemble them locally across ten countries including Canada, the USA, the UK, France, Portugal, Belgium, Norway, Switzerland, and the Czech Republic.

Revenue is generated through one-time unit sales on a quote-based, minimum-order pricing model (minimum 100 EUR net per order), supported by regional direct sales representatives in Germany, Austria, Poland, the Czech Republic, France, Croatia, Italy, and Australasia, plus dedicated subsidiaries PREDL Austria, PREDL France, PREDL Sp. z o.o. (Poland), and PREDL USA. The firm is privately held with no public listing or institutional investor disclosed; Manfred Predl remains the sole managing director (Geschäftsführer).

Products and services

• Schachtboden (Manhole Base-Liner) Plastic manhole base liner made from polypropylene (PP) or glass fiber reinforced plastic (GFRP) that protects concrete manholes from corrosion and wastewater damage. Standard range up to DN 1000 in PP; larger sizes and special designs in GFRP. Designed for precast concrete manufacturers and municipal utility customers.
• PMA-Liner Fully lined manhole system combining the PREDL base liner with PP-CORPROTECT full lining and integrated joint sealing system, providing complete corrosion protection for the entire manhole structure including joints, eliminating the need for field welding.
• CORPROTECT (Predl-Corprotect) Plastic inliner for manhole rings and cones that provides permanent corrosion protection for concrete components. Used in both new construction and rehabilitation projects, ensuring watertightness and buoyancy resistance against H2S exposure.
• Infraschacht (Infra-Manhole) Precast concrete manhole with GRP plastic liner designed for separate sewer systems, featuring separate channels for sewage water (SW) and rainwater (RW) at different heights for bottom differences of 0-850 mm.
• Multro-Schachtring (Multro Manhole Ring) Precast concrete manhole ring with integrated plastic channel for separated water systems. For larger bottom differences, the rainwater line is integrated as a Multro console into the manhole rings.
• Absturzformteile (Drop Structures) Inside and outside drop structures made of synthetic material for new construction or existing manholes. Includes pipe-heads for outside drops, IPK, Inside Drop, and Inside Funnel variants with hydraulic optimization.
• Schachtfutter (Connection Bells) Connection bells fitted in precast concrete bases, available in various diameters, lengths and designs. Made from GFRP for special components or PP/PS for standard types, resistant to wastewater and abrasion.
• FLEXLINER Trenchless manhole rehabilitation system made of wastewater-resistant polyurea synthetic material. The liner is inserted in one piece through the cone, unfolded inside, and backfilled with FLEXgrout. Uses 3D laser scanning for precise fit, requiring no excavation.
• Base-Cover Retrofittable channel cover made of polypropylene that prevents odor emissions and protects manhole rings from H2S corrosion. Access through a 550 mm diameter lid with optional filter system replacement.
• Duplex-Schacht (Duplex-Manhole) Complete plastic manhole system combining advantages of plastic linings in concrete manholes while eliminating traditional plastic system weaknesses. Available in DN600, DN800, and DN1000 with optional concrete filling and integrated sealing.
• Duplex-Hybridschacht (Duplex-Hybrid Manhole) Optimized manhole structure combining precast concrete elements per EN1917 with monolithic PP/GFRP PREDL base liners and PP/PE synthetic lining up to the first joint, using the Duplex ring system.

Expansion highlights5 records

Broad incumbents

• REHAU (Building Solutions): Major polymer-based building and infrastructure solutions provider, including plastic pipe systems for water and wastewater. Overlaps with PREDL on PP-based sewer components but serves a much wider portfolio of construction applications.
• Contech Engineered Solutions: US-based provider of engineered site solutions for infrastructure, including stormwater and sanitary products. Broader portfolio than PREDL but overlapping presence in municipal drainage/wastewater components.
• Sekisui Chemical (Infrastructure): Large Japanese chemical and plastics group with pipe, manhole, and rehabilitation offerings including pipe-in-pipe and trenchless solutions. Broader portfolio than PREDL but overlapping technology in plastic sewer/manhole systems.
• U.S. Pipe (Mueller Water Products): Large US manufacturer of ductile iron and specialty pipe products for water and wastewater infrastructure. Comparable end market (municipal sewer) but distinct material focus and much larger scale than PREDL.

Direct peers

• Wapro AB: Swedish manufacturer of manhole base liners and related sewer infrastructure components. Direct peer to PREDL in plastic manhole liners for wastewater corrosion protection, serving similar municipal and precast concrete customers in Northern Europe.
• Steuler Industrial: German supplier of chemical-resistant linings and polymer systems for industrial and municipal wastewater infrastructure. Comparable to PREDL's CORPROTECT and FLEXLINER lining systems used in manhole and tank rehabilitation.
• Steinzeug-Keramo: European manufacturer of vitrified clay and corrosion-resistant pipe systems for sewer networks. Overlaps with PREDL on corrosion-resistant wastewater conveyance components sold to municipal utilities.
• Hobas (Amiantit): Producer of centrifugally cast glass fiber reinforced plastic (GRP) pipe systems for sewer and stormwater applications. Comparable technology base (GRP) and customer overlap with PREDL's GRP Schachtboden and rehabilitation products.

Emerging players

• ICON Process Systems: Specialty provider of corrosion-resistant process and infrastructure equipment including plastic and GRP components. Comparable in niche material focus (PP/GRP corrosion protection) but with stronger orientation to industrial rather than municipal markets.

Regional players

• Geneva Pipe and Precast: North American precast concrete pipe and manhole producer (a Northwest Pipe Company), and PREDL's franchise partner for North America. Comparable in final manhole product category but primarily a concrete manufacturer, with PREDL supplying the plastic liner.
