The JET Filter system is ideal for dewatering bridge abutments, wing walls, and slope protection.
The JET Filter is a flush mount geocomposite wick drainage system which can be permanently installed on the front side of bridge abutments. It prevents the loss of soil and backfill material through weep holes, is easily unclogged as needed, and relieves panel stress.
Proper venting of the wooden bulkhead is absolute paramount, as water will enter the wall from rain, runoff, irrigation, etc. Forces of nature and physics all work symbiotically to create a fully functioning wall assembly that vents properly and this action maintains the soil density behind the bulkhead.
The purpose of installing weep holes in a wooden bulkhead will relieve the hydrostatic water pressure that may settle or rest behind the wall.
