Systems for renovation of drains and sewers - Lining with a rigidly anchored plastics inner layer (RAPL)
This European Standard specifies performance requirements and describes test methods for pipes and fittings for the renovation of underground drain and sewer systems by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout. It is applicable to plastics inner layers and grout systems with or without steel reinforcement.
This European Standard does not apply to the structural design of the lining system.
NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this European Standard.
Systeme für die Renovierung von Abwasserkanälen und -leitungen - Lining mit fest verankerter Kunststoffauskleidung
Diese Europäische Norm legt Anforderungen und Prüfverfahren für Rohre und Formstücke fest, die für die Renovierung von erdverlegten Abwasserkanälen und -leitungen durch Lining mit einem biegesteifen Ringraum aus statisch tragender Zementmörtelverfüllung, der hinter einer Kunststoffauskleidung geformt wird, verwendet werden. Die mit dem Mörtel verankerte Kunststoffauskleidung dient als dauerhafte Verschalung. Sie gilt für Kunststoffauskleidungen und Mörtel-Systeme mit oder ohne Stahlbewehrung.
Diese Europäische Norm gilt nicht für die statische Bemessung des Lining Systems.
ANMERKUNG Systeme mit mehreren Ringräumen sind verfügbar, jedoch durch Patente geschützt und deshalb nicht im Anwendungsbereich der vorliegenden Europäischen Norm enthalten.
Systèmes de rénovation des réseaux d'assainissement - Chemisage par revêtement de plastique interne rigidement ancré
La présente Norme européenne spécifie les exigences de performance et les méthodes d’essai des tuyaux et raccords pour la rénovation des systèmes de branchements et de collecteurs enterrés par chemisage avec un seul espace annulaire rigide injecté de coulis structurel à base de ciment formé derrière un revêtement de plastique interne. Ce revêtement de plastique sert essentiellement de coffrage permanent ancré dans le coulis. La présente Norme européenne s'applique aux revêtements internes de plastique et aux systèmes de coulis avec ou sans renforcement en acier.
La présente Norme européenne ne s'applique pas au dimensionnement structurel du système de chemisage.
NOTE Des systèmes avec plusieurs espaces annulaires sont disponibles, mais ils font l’objet de droits de propriété intellectuelle ou de droits analogues et ne sont pas couverts par la présente Norme européenne.

Overview
EN 16506:2014 - Systems for renovation of drains and sewers - Lining with a rigidly anchored plastics inner layer (RAPL) - is a CEN European Standard that specifies performance requirements and test methods for pipes and fittings used to renovate underground drains and sewers by forming a single rigid annulus of structural cementitious grout behind a plastics inner layer. The plastics inner layer acts as permanent formwork and is anchored to the grout. The standard covers grout systems with or without steel reinforcement but does not cover structural design of the lining. Multi‑annulus patented systems are excluded.
Key topics and requirements
- Scope and terminology: Definitions for RAPL, anchored plastics inner layer, annulus, grout system, M stage (manufactured components) and I stage (installed, grout-cured assembly).
- Materials and appearance: Requirements for plastics inner layer materials and cementitious grout systems; applicable material characteristics and testing methods.
- Geometric and jointing requirements: Dimensional characteristics for profiled plastics strips, PE sheets with integral anchors, and jointing/welding or mechanical connection methods.
- Performance tests: Normative test methods include:
- Annex A - anchoring strength (pull‑off) test for the plastics inner layer.
- Annex B - I‑stage crushing strength test for the cured lining.
- Fittings and lateral connections: Material, geometric and performance requirements for fittings and lateral reconnection collars.
- Installation, marking and documentation: Guidance on preparatory work, handling, storage, equipment, lining termination in manholes, reconnection procedures, final inspection, product marking and required documentation.
Practical applications
EN 16506 is intended for use in the renovation of underground drain and sewer systems where a plastics inner layer is permanently anchored to a cementitious grout annulus. Typical applications:
- Lining and rehabilitation of sewers and drains to restore structural integrity and provide corrosion protection.
- Rehabilitation projects requiring a durable inside surface provided by plastics formwork and structured grout.
- Systems with or without embedded steel reinforcement where the plastics layer serves as permanent formwork.
Who uses this standard
- Manufacturers of RAPL pipe components and grout systems
- Design and civil/municipal engineers specifying renovation solutions
- Installation contractors and rehabilitation specialists
- Testing laboratories and conformity assessment bodies
- Asset owners and utilities procuring sewer renovation works
