Sustainable Drainage Systems (SuDS) provide an alternative approach to traditional drainage systems. They mitigate many of the adverse impacts of
stormwater run-off on the environment in terms of both volume and pollutants.
SuperFlow Aggregates

The SuperFlow product range is Aggregate Industries’ line of high performance aggregates specifically designed to provide controlled water management within Sustainable Drainage Systems (SuDS).

A porous asphalt which allows water to pass through to the underlying structure. The product comes in various aggregate sizes to suit a range of applications and can be combined with our wide range of other sustainable drainage products to offer the perfect Sustainable Drainage System (SuDS) solution. Designed to reduce the potential impact of surface water drainage in new and existing developments.
Charcon Infilita
Charcon Infilta permeable paving is available in a range of sizes and finishes to suit all applications. The invisible nib profile creates joints that allow fast and efficient water entry into the subbase SuDS solution below. The combination of hidden nibs, range of surface colours and finishes of the Infilta paving range creates an aesthetically pleasing surface finish for all applications.
Ready-mixed concrete Hydromedia®
Hydromedia is an ideal solution for surface and storm water management. It’s a fast draining, engineered concrete pavement solution that rapidly directs storm water off streets, parking surfaces, driveways and walkways. Designed with a subbase to contain typically 20-35% voids, water flows freely through Hydromedia® at rates of between of between 150 litres/minute/m2 and 1000 litres/minute/m2.

Lytag products are classified as secondary aggregates. This means that the quantity of fly ash being tipped is reduced and virgin aggregate extraction is reduced. By considering the use of Lytag products at an early stage in the design process, you have the potential to reduce the quantities of construction material required in a project. This leads to overall cost savings. Due to the reduced weight of Lytag products, larger volumes can be transported, reducing vehicle movements both on the public highway and site.


An interlocking cavity grid system, Grassgrid offers natural looking hard standing for vehicles and strengthening of embankments.
