This detailed and comprehensive document has been developed using Marshalls’ vast experience in researching, promoting and designing the UK’s most popular permeable paving system. It covers all aspects of concrete block permeable paving including hydraulic and structural design, installation and maintenance as well as considering CBPP’s place within a holistic water management scheme.
Martlesham Park & Ride car park, which was installed in 2003, is one of our oldest Priora permeable paving installations. We caught up again with the original designer, Simon Curl of Sussex County Council, to find out how his design is standing the test of time. Watch this video to hear Simon’s approach to common queries such as incorporating tree roots and services – and also to find out about the maintenance regime they’ve employed to keep the surface performing.
In spite of years of evidence to the contrary, people still assume that permeable paving will fail because the joints quickly get clogged up. We’ve been revisiting some of our older Priora systems and, using the American Standard method ASTMC1781/C1781M, undertaking in-situ permeability tests to see how they’re working. This report shares our observations along with the results of the tests.
