SuDs (Sustainable Urban Drainage System)

RoadStone permeable paving system is the perfect solution to alternative of traditional pipes, drains and culverts approach to a development and its drainage strategy. It is the more sustainable alternative to dealing with storm water at source.

Requirements for Developments to Sustainable rainwater management

Recent push by government agencies to incorporate ABC Waters (Active, Beautiful, Clean) guidelines for development of the projects. As our environment becomes more developed, there are increasing surface areas that are impermeable, hence increasing the chance of flooding in developments.

Permeable Pavers

RoadStone Permeable Concrete Pavers mimic the natural process that occurs on the ground’s surface. The role of a segmental permeable pavement system is to allow water to pass through the paving stones joints and seep into the ground naturally or to be retained in the base/subbase structure rather than turning into runoff headed directly into the sewer system. It also filters out suspended solids and pollutants, keeping them from polluting the water stream.

S ustainable urban drainage systems (SuDS) mimic natural drainage processes by employing these three key principles: water quality, water quantity and biodiversity/amenity.

The Roadstone Aquaflow system provides the means to not only achieve but excel in the three key SuDS principles. Through considerate design, careful selection of techniques and materials, the Roadstone Aquaflow blocks and the Roadstone. Aquaflow system deliver the following benefits:

Reducing water quantity - Dealing with surface water at the source reduces the effects of urbanization and the impact of localized flooding
Improving water quality – Roadstone Aquaflow. provides two levels of storm water treatment: removing harmful pollutants and protecting the environment downstream
Contributing to the biodiversity - Contributing to the biodiversity of development by working in conjunction with other SuDS techniques. Roadstone Aquaflow. allows any hard standings, including roads, to be used as drainage, producing a traditional looking surface with many desirable features.

AQUAFLOW® system
Roadstone Aquaflow has used research and design to evolve the Roadstone Aquaflow permeable paving system into one of the most cost effective and functional SuDS within the marketplace.

The Roadstone Aquaflow system has a unique subbase design incorporating SC Intergrid which reduces construction costs whilst giving superior structural performance. Water quality improvement is realised through the use of our tried and tested Inbitex Geotextile which removes the requirement.

for downstream pollution control. The patented Roadstone Aquaflow system fits neatly within any block paving project, where your paving design becomes your drainage design and vice versa.

Roadstone Aquaflow SuDS can be designed as fully attenuation, fully infiltration or as a partial infiltration system. Attenuation (tanked) systems capture storm water to be collected and released in a controlled manner into sewers and downstream watercourses. Infiltration systems allow rainwater to be infiltrated into the ground mimicking a green field environment. Storm water leaving the Roadstone Aquaflow system is cleaned and filtered through the Inbitex Geotextile layers that promote microbial action. Water quality improvement allows secondary nonpotable uses to be carried out such as flushing toilets and watering the garden. The Roadstone Aquaflow system can be designed for use in both trafficked and pedestrianised areas, allowing the collection and treatment of storm water from any paved surface.

Roadstone Permeable Pavers

*Water permeates through indents at the edges of the pavers, retaining the aesthetic value of the paviours while allowing permeability.
