The ultimate range of permeable drainage aggregates

Traditional paved surfaces are designed to shed water. Unfortunately this means that local drains can quickly become overwhelmed after heavy rainfall.?With the apparent rise in extreme weather over recent years, flood management has become a high priority. Tarmac has responded with a range of specialist aggregates designed to work with various pavements types, to improve water management and reduce the risk of flooding.

ULTIFLOW is a range of versatile, high performance aggregates with excellent drainage characteristics.?Our investment in process technology ensures a high level of control over aggregate production and grading, for a consistent product that delivers predictable water holding and flow characteristics and meets the highest industry standards.
