RV System

The system uses two proven materials: polypropylene (PP) and unplasticized polyvinyl chloride (PVC-U).

Each one offers specific benefits:

• Polypropylen (PP) – výjimečná thermal and chemical resistance, vysoká houževnatost, výborná zpracovatelnost. Díky ní lze vytvářet dna šachet s dokonale hladkou vnitřní stěnou odolnou vůči otěru, zanášení i vnějším tlakům.
• PVC-U – time-tested material with high abrasion resistance a strong outer layer, which easily withstands materials used for bedding, compaction and loading in the field.

The result is a plastic shaft that meets high demands of engineering structures and withstands temperatures and more aggressive chemical environments in the long term.

RV-System OSMA is designed to withstand even extreme mechanical conditions.

Key features:

• reinforced ribbed walls shaft bottoms – effectively distribute soil pressure, protect the structure from deformation and guarantee long-term stability
• flexible connection of shaft pipes and telescopes – compensates for soil movement and terrain loading
• possibility of installing cast iron covers – the structure safely withstands wheel loads up to 400 kN, making it a suitable system not only for gardens and courtyards, but also for traffic areas, parking lots and roads.

Tightness is one of the most important parameters of every sewer shaft. RV-System OSMA uses a multi-edge sealing element made of durable rubber housed in a specially shaped collar chamber.

The sealing element contains:

• wiping blade
• limiting blade
• fastening blade
• sealing blade itself

The combination of all these elements enables safe sealing under overpressure and underpressure up to 0.5 bar. Tightness is maintained even with slight pipe deformation or deflection, which increases shaft reliability during long-term operation.

RV-System OSMA forms a complete range of elements that allow the construction of inspection shafts of various depths up to 4 meters. It also allows subsequent connection of new sewer branches and connection to various sewer systems, including standard house and rainwater systems.

Thanks to thoughtful design, the system also offers easy inspection and monitoring. With its flexibility, it is suitable for residential construction, renovations as well as municipal and industrial infrastructure.

The low weight of plastic shafts brings several advantages over concrete or masonry structures:

• lower energy consumption in production and transport
• lower CO₂ production
• easier handling and faster assembly
• 100% recyclability of all components

RV-System OSMA meets demanding environmental criteria and represents a modern, sustainable infrastructure solution for the future.
