When to use polypropylene
Polypropylene (plastic) channel drainage is appropriate for most domestic applications — patios, garden paths and residential driveways. It is lighter and easier to handle on site, and generally more economical for A15 and B125 applications.
- A15 domestic patios and paths
- B125 residential driveways
- Threshold drainage
- Where weight and cost are primary considerations
When to use polymer concrete
Polymer concrete is a composite material offering greater compressive strength, chemical resistance and dimensional stability than polypropylene. It is the standard material for C250, D400 and F900 systems, and is also available for some A15 and B125 applications where a more robust solution is required.
- C250, D400, F900 commercial and industrial applications
- Environments with chemical exposure
- High-load applications
- Where dimensional accuracy is critical to the installation
