After successful completion of tree pits installed in the Netherlands last year, SureSet were once again approached to help with another project. This time the project was situated in the heart of Amsterdam at Oudekerksplein (“Old Church Square”). This is a square named after the 14th century church Oude Kerk, which dominates the square. Oudekerksplein lies in the heart of the famous Red Light District and is visited by thousands of tourists every year.
The square is under re-development to encourage and introduce cafe’s, restaurants, shops and artist workshops to settle in the square for the hundreds of daily tourists who visit the Oude Kerk.
Amsterdam City Council were looking for a surface which would allow adequate water and oxygen to established tree roots, but also create a hard wearing surface which would be suitable for pedestrians and vehicles alike. The material needed had to match the existing cobbled pathway and roads in the square. The answer proposed was SureSet Resin Bound Permeable Paving.
To ensure a stable final surface, and a fully permeable system, the SureSet material was laid at a depth of 50mm onto a substrate of 5-40mm well compacted crushed stone.
The work carried out in July by SureSet not only included 100m² of 10mm Charcoal laid over 9 pits but also the use of SureSet’s Flexi-zone around the base of the trees; this allows the trees to grow and reduces any chance of strangulation.
In addition to this, to help reduce the possibility of cracking over these large pits, SureSet’s Crack Reduction Membrane (CRM) was installed on each pit prior to the final installation.
The project was completed by a small in-house installation team over just two days. The finished look is exactly as requested and the 10mm Charcoal compliments the surrounding paving.
Oudekerksplein now have an extremely low maintenance surface which is fully permeable and will not allow weed growth, and no loose gravel.
