Access Chambers | STAKKAbox™ from Cubis

STAKKAbox Chambers

STAKKAbox access chambers manufactured by Cubis are a range of modular, structural and sectional preformed access chambers manufactured from modern technology polymer materials – STAKKAbox chambers provide significant advantages compared to conventional brick built access chambers. The chambers are lightweight but durable and deliver impressive labour productivity gains, time saving benefits and associated cost reductions to the installation contractor.

Specify STAKKAbox Chambers

Cubis’ STAKKAbox™ access chamber systems are adaptable to the unique requirements of each construction site. This means ordinary site tools can be used to retrofit chamber systems around existing networks by drilling duct entries or cutting the chamber sections horizontally. The seamless integration across the Cubis chamber product range enables the construction of bespoke systems that significantly reduce costs of access chamber construction through time savings. Cubis’ chamber options and accessories range allows installers the ability to simply place, connect ducts, backfill and walk away.

Types Of STAKKAbox Access ChamStakkabox Sectional Access Chambersbers

Sectional

Sectional Access Chambers use individual STAKKAbox sections, which are stacked to offer flexibility and required chamber depth. Each ring section interlocks with the units above and below. Manual lifting of this chamber is safe due to the lightweight properties of each section.

Stakkabox Modular Access Chambers

Modular

There are a variety of options for clear openings of chambers. Access chamber sections are available in ‘solid rings’ or as part of a system of modular component parts.

Stakkabox Structural Access Chambers

Structural

Structural access chamber use twin walled STAKKAbox™ sections to provide a strong, yet lightweight product. Complete assembled chambers feature horizontal and vertical ribs to allow for efficient loading.

ULTIMA Connect | The Next Generation in Chamber Access Systems

Variability in Size

ULTIMA Connect offers a huge range of chamber dimensions due to the large number of standard sections and the variability offered by the ULTIMA Connect system manufactured by Cubis.

Flat Pack Option

STAKKAbox ULTIMA can be shipped ‘flat packed’ to reduce shipping costs. A large chamber, as used on power stations or waste water treatment works, could be reduced to a number of pallets rather than occupying an entire transport vehicle or lorry.

Flexibility in Construction

Cable duct entries can be quickly and safely formed on site. Overbuilding or benching is easily achieved. Fine top level adjustment is possible by horizontally cutting the top section of the chamber.

Chemical Resistance

GRP outperforms traditional construction methods for chemical resistance during its buried life, resulting in a product that offers longer installed life.

Lightweight

Due to the sectional twinwall design and the GRP material, most ULTIMA Connect 150mm deep sections fall under 25kg in weight, making them suitable for a single person lift under manual handling regulations.

Fast & Easy to Install

ULTIMA Connect 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.

Strength

ULTIMA Connect offers the ability to offset joints between sections to provide a strong brickwork effect improving side wall performance.

Smooth Outer Walls with Lip to ‘Key In’

Gaps in the outer wall will negatively impact the effectiveness of compaction around the chamber. STAKKAbox™ chambers have smooth outer walls and an outer lip which keys into the backfill.

STAKKAbox ULTIMA Connect Access Chambers

STAKKAbox ULTIMA Connect Access Chambers | The Nemo Link® is a truly international collaboration in the construction of a High Voltage Electrical Interconnector between the UK and Belgium’s electricity grids. Consisting of subsea and underground power cables connected to converter stations within each country, the HV cables distribute electricity in either direction. Cubis Systems was selected to provide a HV receiver and diversion chamber system – this resulted in the delivery of 152nr 1.5m up to 2.6m ‘flat pack’ STAKKAbox ULTIMA Connect chamber systems for construction in-situ on site.

The flat-pack design of the ULTIMA Connect system permitted rapid installation of the chambers around the cable duct bank with labour productivity savings and benching over underground services and creating cable duct entries for the 33kV high voltage power cables.
