Infiltration Mix has been engineered for the use in areas where water runoff from commercial buildings and car parks through a bio filtration system is required. The purpose is to slow water movement to storm water systems, and clean the water, allowing minerals to be absorbed by the plants. It also aids in silts being trapped in the garden and pathogens removed by the biological and physical processes. These rain gardens create a fantastic habitat for birds, bees, insects and butterflies. There is a slightly lower percentage of Organic Compost in the Infiltration Mix compared to the Rain Garden Mix, for those planting situations where lower Nitrogen levels are better suited for the plants or environment.

Barks & Mulches
Premium Bark Nuggets 20mm is a premium grade bark product made from carefully selected and processed pine bark. These decorative nuggets look great on the garden and create a nice finish to your outdoor area.

During the refining process the nuggets also pass through our state of the art wash plant to remove stones and other impediments. Our Premium Bark Nuggets are both CSS Bark Mulch - Normal Grade, and CSS Bark Mulch - Premium Grade approved. They also meet the NZS5828:2015 / EN1177:2018 playground surfacing standard
