AfterShock soil absorption restorative from Cape Cod Biochemical Co. is designed to help restore drainage to clogged and sluggish drainfields and drainage structures. The USDA-approved, environmentally safe product contains multi-strain Bacillus spore-bearing bacteria and a time-release oxygen source that biologically digests the solid material that normally clogs soil absorption areas. The oxidizer accelerates the activity for an extended period, also helping degrade sulfides in the biomat to further promote drainage. It is designed to be used in conjunction with high-pressure waterjetting and soil fracturing equipment. It can be applied in one day, eliminating the need to keep the system exposed for repeated site visits. 800/343-8007; www.septiconline.com.
