Joint Filler

HydroSTON 80 vehicle pavements need to be installed with average 4mm gaps between pavers to ensure lock up of the pavement and provide flexibility of movement of individual pavers. Joints should be filled and compacted with minimal fines 1-3mm crushed rock. Specially graded joint filler is available from HydroCon in 20 kg or 1 tonne bulk bags. HydroCon Joint Filler can also be used for filling gaps and finishing off HydroSTON 50 pedestrian pavments. 20 kg bag dimensions: 380 mm x 660 mm x 200 um or approx. 340 x 580 x 100 mm when full.

Key Features & Benefits

HydroSTON pavers have a wide range of benefits and applications: Fully permeable – HydroSTON pavers are 100% porous Facilitate on-site water retention and harvesting of stormwater runoff for non-potable use Improve water quality by filtering stormwater runoff and removing pollutants at source Reduce peak-flow runoff and take pressure off existing stormwater drainage systems Collect and detain runoffs without open drains or pits Reduce flooding and surface ponding Provide subsurface on-site retention, also for roof runoffs Assist in replenishing groundwater and aquifers Increase water supply to trees and landscaped areas Allow root aeration Improve urban micro-climates by moderating evaporation and reducing reflective heat Contribute to urban water security Improve permeable area property ratios Provide a viable and cost effective supplement to existing storm drainage systems Have low life-cycle and maintenance costs
