- fasteners are not used. Many sealants and
- adhesives are temperature dependent. A tendency in
- cold weather is to use mechanical fasteners. Call
- Greenstreak for specific
- recommendations/precautions for use of mechanical
- fasteners. Obviously if a waterproofing membrane is
- used, penetration of that membrane with mechanical
- fasteners would not be acceptable.

- NOTE ** Delete references to applications not required
- below.
-
- A. Verify that indicated components of waterproofing system
- have been installed.
-
- B. Verify that horizontal applications have sufficient slope
- to drain.
-
- C. Verify that collection piping has sufficient slope to
- drain.
-
- D. Verify that invert elevation of collection pipe is below
- construction joint in vertical subgrade structure.
-
- E. Do not begin until substrates are dry, dew and frost
- free, and free of dust or other materials which prevent
- adhesion of sheet to substrate.
-
- F. Submit written notification of unacceptable conditions or
- substrates.
-
- 3.2 INSTALLATION
-
- A. Install geocomposite sheet to drain water to drains
- and/or piping indicated on drawings.
-
- B. To splice, overlap two rows of dimples and mechanically
- interlock with rubber mallet. Lap excess fabric a
- minimum of 3 inches and secure as necessary with
- adhesive. Shingle laps in the direction of flow.
-
- C. Face fabric towards hydrostatic source and face core
- towards subgrade structure.
-
- D. Adhere geocomposite sheet to substrate using adhesive.
- NOTE ** Consult Greentreak for use of mechanical fasteners.
- See note in Part 2 at furring strips. Delete the
- following paragraph if mechanical fasteners are not
- used.
-
- E. Fasten geocomposite sheet to furring strips using
- mechanical fasteners, as recommended by manufacturer.
-
- F. At terminations of geocomposite sheet, roll and tuck
- excess fabric to back of core to prevent intrusion of
- soils into core.
-
- G. At subdrainage piping, lap additional sheet drain fabric
- over and around collection pipe. Place geocomposite
- sheet behind perimeter collection pipe.
-
- H. Promptly cover sheet to protect from damage by wind and
- ultraviolet.
-
- I. Repair tears and punctures in fabric with new filter
- fabric adhered over damaged area.
- NOTE ** Be sure to include in the earthwork section a
- requirement that backfilling over geocomposite
- sheet must be performed in compacted lifts.
-
- J. Verify that backfill is performed in compacted lifts.
- Sequence tall applications requiring bands of
- geocomposite sheet with backfill to accommodate vertical
- movement of sheet during compaction.
