RapidSTACK chambers are a superior alternative to traditional class B engineering brickwork, block work or re-enforced cast insitu concrete. RapidSTACK is extremely quick to install and is available in a wide range of sizes. The system is cost effective resulting in significantly lower labour, plant and road closure costs.

Glass Reinforced Polyester Resin (GRP) is an ideal material for access chamber products due to its high mechanical and chemical properties, fire retardancy and the fact that it does not suffer from creep. Creep is the tendency of a solid material to permanently deform under continuous or long term loading or mechanical stresses, such as loading from traffic.

  • Fast and easy to install
    RapidSTACK chambers are significantly faster to install than conventional alternatives, with complete installations typically taking up to one hour. This results in reduced costs for the installer.  Only the largest sizes in the range require specialist equipment or plant in order to install the chamber. 
  • Sectional design
    Chambers are built to required depth by adding 150mm stackable sections that are light meaning they can be manually lifted. Each access chamber possesses vertical and horizontal ribs,  resulting in a product that is strong vertically and on the sidewall. For most applications, RapidSTACK doesn’t require specialist backfills, reducing installation costs.
  • Variability in size
    RapidSTACK can be used to create virtually any conceivable access chamber clear opening. RapidSTACK offers a huge range of chamber dimensions thanks to the number of standard sections and the variability offered by the system.
  • Flat pack
    RapidSTACK chambers can be sent to site in ‘flat pack’ format, allowing for flexibility in delivery and installation.
  • Flexible during installation
    Chambers can be adapted to suit on-site conditions with standard tools
    • Overbuild over existing networks
    • Introduce duct entries for cable entry
    • Top-section fine adjustment
  • Fire Retardant
    • Fire retardant to BS476 Part 7 Class 2
    • Material tested in accordance with ISO 4589-2 Oxygen Index Test

 

RapidSTACK is commonly used for the following applications:

Highways

  • Motorway Communications
  • Drainage

 

Power & Energy

  • High Voltage power cable jointing
  • Low Voltage power cable link boxes

 

Water

  • Valve chambers
  • Telemetry chambers

RapidSTACK is suitable for installation in environments rated to E600 under EN124, in accordance with Cubis' installation guidelines.

RapidSTACK is manufactured in Glass Reinforced Polyester Resin (GRP).

Benefits of GRP:

  • High strength to weight ratio
    The material is significantly lighter than other conventional materials that can provide the same inherent strength.
  • High temperature range
    GRP is a thermoset material, meaning that it irreversibly cures when heated. As a result, GRP will not melt, drip or form molten droplets.
  • Fire retardancy
    RapidSTACK won't catch fire and has low smoke properties. This means the product can be used in enclosed areas such as tunnels and underground transport.
  • High mechanical properties
    The material is non-conductive, has a low coefficient of expansion and is resistant to weathering. GRP possess high tensile and bending strengths combined with high stiffness. The material is superior in mechanical strength properties compared to those of commodity thermoplastics such as the Polypropylene and the Polyethylene family.
  • Chemical resistance
    GRP is chemically inert, which means it is not chemically reactive. Its high chemical resistant nature is essential for ensuring a long service life when buried underground. GRP is not affected by frost, acids, alkalis or diesel, all of which will affect the lifespan of concrete products.
  • Not susceptible to creep
    Creep is the tendency of a solid material to permanently deform under continuous or long term loading or mechanical stresses. For access chambers, this is related to the process where an unsupported or non-compacted sidewall could move over time due to loading from traffic. This makes RapidSTACK chambers ideal for carriageway installations.

Chamber Accessories

Access chambers can be pre-fitted with the following accessories:

  • Duct Entry
  • Cable Management
  • Steps

Base sections

Standard Base

We extrude 100% recycled Low Density Polyethylene chamber bases to suit any chamber size. These are securely fitted to the bottom ring section of a chamber to provide a clean easy finish to the floor of the chamber. There is no requirement to 'float' a floor on site and the floor prevents vegetation and silt from entering.

 

Sump Base

Base section has a false floor with low-point for water to allow for drainage.

Meets the requirements of MCX 0815 for Motorway Communications.
