​Cascade can offer through our approved suppliers and partners a wide range of access chambers and covers for all applications. Chamber sections are made from composite, meaning they are lighter than the concrete ones, with no loss to quality. 

​Key Features 
The chamber sections are DN400 loading and are BS5834 compliant. Other key advantages are:
​

• UK Manufactured from 100% recycled post industrial PVC. 
• Structural design - no concrete surround required. 
• Far lighter than concrete. 
• Massively reduced H&S implications for site personnel. 
• Extensively used throughout the UK by most water utilities and their contractors. ​​
