ULTISuDS BBA HAPAS certified as a porous asphalt surfacing system for use within a pervious pavement for surface water source control, in lightly trafficked areas such as car parks, residential and urban roads.

An integrated sustainable drainage solution which reduces the risk of flooding by managing surface water at source.

By combining engineered porous asphalts and permeable aggregate support layers with other environmental measures like infiltration strips, ponds and swales, rainwater is intercepted and absorbed before it enters the watercourse.

UltiSuDS is designed to capture and control rainwater from the moment as it makes contact with the porous paved surface. This results in significant reductions in the speed and volume of discharged water, reducing the risk of flash flooding.

Features and benefits:

Achieves a hydraulic conductivity rating at installation of 5000 mm/hr.
As part of a sustainable drainage solution, it meets the requirements of planning regulations and the Code for Sustainable Homes.
Enhanced safety for vehicles and pedestrians by reducing standing water and ice.
Traps and retains pollutants like hydrocarbons and heavy metals.
When water storage measures are available it can aid water harvesting and re-use.
