At Peter Nelson Paving, we believe that utilising a permeable resin bound surface is vital for a residential or commercial area. Over recent years Ireland has been hit by a number of extreme flood events and we must take action to help prevent flash flooding and urban surface run-off.
Permeable resin bound paving allows for natural filtering of water as it seeps through the sub-base and back into the ground. This paving option is compliant with SuDS (Sustainable urban Drainage Systems) and actively contributes to flood prevention.
Resin Bound vs Bonded
Bound: Permeable smooth surface compliant with SuDs regulations
Resin bound surfacing, or ‘trowelled’ paving is made from a blend of aggregates coated with a clear UV-stable polyurethane resin. To ensure that each aggregate particle is completely coated in resin, the two elements are combined in a force-action mix process to form a cold-pour mixture. The mixture is then poured and hand-trowelled to form a smooth, colour-constant, accurate surface with no loose stones. It is recommended that a resin bound surface should be laid to a depth of 15mm for a pool surround, footpath or terrace and 18mm for a driveway and car park. Resin bound surfacing is water-permeable when laid on an open surface asphalt.
What is resin bound paving?
Resin bound paving fixes together small stones with high-tech resin to form a firm, attractive surface. It creates many small gaps that allow water to drain through into the ground.
This technology combines the best of other surfaces:
- The drainage and appearance of loose gravel
- The durability and convenience of block paving
- Long-term performance of block pavers
