Features & Benefits
All Weather Construction
Unlike with brick-built chambers where freezing temperatures can stop work, POLYvault™ can be installed in all types of weather.
High Strength to Weight Ratio
The material is significantly lighter than other conventional materials that can provide the same inherent strength.
Structural Ribs
Each access chamber possesses vertical and horizontal ribs, resulting in a product that is strong vertically and on the sidewall.
Single Wall Design
Due to the Single wall design, individual sections are light meaning they can be manually lifted.
Flexible During Installation
Chambers can be adapted to suit on-site conditions with standard tools to overbuild over existing networks, Introduce duct entries for cable entry and for top-section fine adjustment.
Drop-In Covers
Covers are ‘dropped’ in the inner-lip of the chamber and do not require a frame.
Fast and Easy to Install
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. No specialist equipment or plant is required in order to install the chamber and there is no need for specialist box builders.
