Channels… Ducts… Troughs
Precast concrete channel, duct and trough systems offer a versatile solution for the housing of utility and building services.
These systems are engineered to meet the stringent safety and performance standards, specifically in accordance with BS EN 1433 for channels and BS EN 124 for lids.
The trough and lid configuration of precast concrete ducting offers the following benefits:
- Protection – The robust concrete structure shields underground services from accidental damage during excavation or other ground-level activity.
- Visibility – The presence of concrete ducting serves as a clear marker for utility installations, reducing the risk of unintended Accessibility – The removable lid design allows for easy access to the housed service, facilitating efficient maintenance and repair work.
- Security – The durable construction and secure lid system offer enhanced security protection against unauthorized access, tampering or local wildlife.
The advantages make precast concrete ducting, the best choice when compared to direct burial or overhead suspension methods for utility and service installations.
The versatility of the precast system allows it to accommodate a wide range of services, including power cables, telecommunication lines and various typers of pipework.
Rectangular Ducts are available in the following dimensions set out in the table below, as indicated by the key letters on the drawing illustrated right.
CAD drawings and weights of the channels can be downloaded from the technical drawing section. We can service bespoke sizes, made to your specification, as well as a standard range for quick deliveries
