How do HYDROPAVERS™ Permeable Paving tiles work?
Available in attractive colours, HYDROPAVERS™ pervious pavers behave like a sponge, retaining water and eventually letting water flow through without inhibition. Run-off is eliminated or reduced in two quite distinct ways.
First and most importantly the permeable paver ABSORBS and retains the rainwater. For example if 5mm of rain falls over an hour, all the rainwater will be retained inside a 55mm paver. (Auckland rainfall averages about 3.5mm per day). This rainwater can then evaporate back into the air; no water passes through the pervious pavers or runs off into drains.
Secondly, once the brick is saturated by heavy rain the rainwater will flow through the paver. Typically the pavers are laid onto an aggregate bedding; but the installation design depends on the geotechnical features of the ground to be covered.
NOTE: Because of the way HYDROPAVERS™ behaves, compaction of the ground (by vehicle traffic for example) is much less of an issue. Councils tend to classify any ground that carries vehicles, even natural surfaces, as impermeable.
HYDROPAVERS™ is a ceramic product compressed at 1600 tonnes and baked at 1200°C. This means that your paved surface will remain pervious for its lifetime. The high compressive strength and durability mean the permeable pavers have a very long life.
For Councils to accept that the surface is permeable (ie. not impermeable) the installation has to be able to deal with a one-in-ten year rain event of 10mm. HYDROPAVERS™ permeable pavers can absorb more than that. Some concrete paving products call themselves permeable but they rely entirely on the spaces left between the pavers – which can clog up of course and absorption by the base aggregates.
HYDROPAVERS™ pavers are available in dimensions of 300 x 300 x 55 and 200 x 100 x 55. Thicknesses of 30mm or 40mm can be supplied on special request. Black, Off-White and Grey pavers are also available in a larger 600 x 300 x 55 format.
HYDROPAVERS™ will not clog, is very strong, and is easy to lay. Call us today to discover how these permeable pavers can turn your paving project into a good looking, long lasting, quick draining success.
