Bioretention & Rain Garden Soil

 

Bioretention cells are depressions in the landscape that capture stormwater before it can enter waterways. Stormwater is collected and percolated back down into the ground where it is filtered through a media or “bioretention soil.”  The performance criteria sought in all bioretention soils include:

  • High percolation rates to prevent surface ponding over 48 hours.
  • Large capacity to sequester pollutants as water percolates through.
  • Support for the growth of plant populations.

Read Bioretention / Rain Garden Mix 

Our precision blend of sand, soil and compost provides these performance characteristics. The final mix shall have an organic content of between 2.5 and 4.0% by weight, pH of 5.5 to 7.0 and conform to the following gradation requirements for material passing a Number 10 sieve:

Sieve % Passing
#10 100
#18 70 - 95%
#35 40 - 75%
#60 20 - 35%
#140 10 - 20%
#270 8 - 15%
Clay 2 - 5%

 

Notes:

  1. Maximum size aggregate = ½”
  2. Maximum retained on the 2mm sieve = 15%
