Collecting water and filtering out sediments

Natural biofiltration system

Rain garden mixes provide a natural biofiltration system that not only protects water quality and reduces stormwater runoff, but they also provide an effective solution for increasing square footage in developed areas where there is an increased potential for flooding.

Plaisted Rain Garden Compost Mixes absorb most rainfall while filtering out sediment and pollutants. They also store water for the short term to be used by plants, permitting clean water to infiltrate the soil and subsoil slowly, thus recharging the groundwater.

Plaisted Rain Garden Compost Mixes are a homogeneous blend of construction sand and leaf compost, precisely blended using our Accublender™ technology. Any combination of materials can be used to make your customized blend:

  • 70 to 90% washed clean construction sand
  • 10 to 30% organic leaf compost

Recommended soil depths for planting: Soil depths range up to 3 feet. Soil compaction decreases porosity—keep construction vehicles off the mix and use rubber-tracked equipment when being installed.

ACCUBLENDER

Our four-bin Accublender™ is used to create these mixes. It features a computerized blender with an on-board screen deck that removes oversized particles and a mechanical paddle wheel that ensures uniformity. It automatically adjusts for flow rates of material and stops the conveyor belt when feed bins need to be replenished.
