Overview

Topmix Permeable is a fast draining flood reducing concrete.

Topmix Permeable is a fast draining concrete pavement solution ,that as part of a sustainable Urban Drainage System rapidly directs stormwater off streets, parking surfaces, driveways and walkways.

Topmix Permeable concrete can play a fundamental role in the majority of Sustainable Urban Drainage Systems (SuDS) design, providing a practical, long term answer to surface water flooding that can be implemented quickly and cost effectively. This permeable concrete is an alternative to granular bound materials and no-fines concrete.

Topmix Permeable is a fast draining permeable concrete solution.


Where can Topmix Permeable be used?

Topmix Permeable can be used in conjunction with, or as part of other sustainable Urban drainage systems .The material is designed to sit under other free draining Suds systems, to help with giving structural rigidity to the overall system.

Why use Topmix Permeable?

Additional info

Unlike conventional concrete, Topmix Permeable has a high void content of between 20-35%. This allows surface water to drain through into the sub-strata and dissipate naturally, reducing the risk of surface water flooding and watercourse contamination.

The technical properties of Topmix Permeable are as follows: Void content up to 35%, Flow rate: Up to 1,000l/m2/min, Compressive strength: 10-20N/mm2 and Flexural strength: 1.5-3N/mm2
