  • Vegetated Environmental SolutionsColumbia River Restoration Bioengineered SolutionsShoreline Protection • Retaining Walls • Slope Stabilization • Erosion Control
  • Vegetated Environmental Solutions INTRODUCTION Patented The ecologically advanced Envirolok vegetated system provides permanent erosion control. Envirolok’s patented system provides immediate stabilization, erosion control, and a permanent vegetated solution. Envirolok is adaptable to water or dry land sites. Envirolok’s encapsulated soil bags and spikes Patented combined with the engineered strength of soil reinforcing materials supply the connection necessary for an ecological vegetated solution.

  • Envirolok® Native Sod™ is a pre-vegetated mat of a deep rooting native species with a light geotextile or biodegradable core. Once laid on a surface, the plants take root in the soil and quickly form a secure vegetated mat to hold the surface soils in place against erosive forces.E N V I R O L O K ® N AT I V E S O D ™ • Easy installation • Instant erosion control • Immediate vegetation • Low maintenance • Multiple cores available * See representative regarding lead time and availability 9

They control erosion; they increase• Envirolok wall becomes a infiltration and purify rainwater and runoff beautifully restored native prairie so that the aquifer remains full and pure. that provides habitat year round• Sequesters oxygen and moisture• Provides safe habitat for amphibious species L Shallow turf roots Deep native roots10 W W W.

  • I N S TA L L AT I O N1. Filling and Closing Envirolok BagsFill the Envirolok bags with an engineered soil using an Envirolok Bag Filler.The soil properties should consist of 60% sand, 20% high grade compostand 20% top soil. The engineered soil may change to meet the specificproject needs. Excavated material may be used to backfill duringconstruction. Clay and silt are not appropriate fill material. All bagsshould be filled consistently and will be closed with a UV resistant zip tie.Bags may also be sewn or closed using hog-rings.2. PreparationDig a trench no less than 3” deep, 16” wide for the length ofthe structure. Embedment depth will be specific to the project.Compact bottom of foundation using hand tamper or vibratoryplate compactor. This trench serves as toe stabilization and willprotect the structure from undermining. Larger structures willrequire engineering.3. Placing Envirolok BagsThe foundation course will begin with placing spikes in the excavatedtrench at the desired location of the first row. Place filled bags next toeach other, seam side in, horizontally, the full length of the structure.The “snorkel” of the bag will land on top of the previously placed bag.4. Placing AdditionalBag CoursesAfter laying one entire course of bags, compact the soil ensuring a solidand uniform structure.Insert two spikes in the top of each bag evenly spaced. The spikeplacement will vary with the slope of the structure and should be placedin the center of the bag contact area between courses.12 W W W. E N V I R O L O K . C O M
  • 5. Backfilling and Compactingthe StructureBackfill and compacting after each course ensures strength and stabilityof the system. Backfill should be compacted to the specifications of thewall design. Backfill must support vegetation and be free draining.6. Geogrid PlacementStructures that require geogrid reinforcement will be specified by anengineer. After compaction, geogrid placement will begin at the front ofthe bag course and will go towards the existing material. Place spikes ontop of the geogrid and continue placing bag course. Geogrid should bepulled tight prior to backfill. Continue with course compaction.7. Top RowInstall the top row of the structure the same way the other courseshave been placed. Tuck the “snorkel” under to give a finished look to thelast course. If specified, the top row may need to be anchored into theexisting landscape.8. Vegetation EstablishmentOnce the wall is completed, vegetation is the final step. Native vegetationis recommended because of its adept root structures that will bind thewall together forming a monolithic structure that will renew itself yearafter year. Using vegetation suitable for your local climate is necessaryfor a successful project. You may build the wall and place live plants in thecourses as you build the structure. Live plant material should always beplaced in between the courses. Cutting the bags open and planting intothis cavity is NOT recommended. It is recommended that a combinationof live plants and seed are used to ensure proper vegetation.Brochure Photo Credits: Sunmark Environmental ServicesAqua Terra Stormwater • Agrecol LLC • Dixon Shorelines 13
