Approximate size and shape of opening
1. The black outline represents a four foot opening vertical or horizontal.
Layout area on plastic
2. Lay down a plastic sheet at least two feet larger than the opening, place rocks or sticks on the plastic in reference to the opening.
For a shaft, prepare ropes to lower false bottom
3. Tie a stick or similar object to one end of the rope to act as an anchor. Place anchors approximately 12-18 inches in from each corner.
Pour foam on plastic
4. Carefully pour foam within the marked area. Be careful not to disrupt the anchored ends of the rope.
Cover entire area and ends of ropes
5. Fill the entire area with foam to a thickness of 2-3 inches.
Allow foam to cure for 15-20 minutes
6. Allow foam to cure for 15 minutes or until no longer tacky.
Pull up foam from plastic and place over opening
7. Place false bottom or bulkhead over opening.
Find edge of opening
8. Cut a notch in the foam to expose the outer edge of the opening.
Locate all four sides of opening
9. After cutting several notches, proceed to trim.
Don't cut the ropes! 10. When trimming the foam, be
careful not to cut the ropes.
Trim to fit, test and adjust as required
11. To prevent cutting the ropes, pull the rope through the foam until it reaches the anchor.
Foam can be used to form shafts or adits 12. Your false bottom or bulkhead is now ready to be placed. If any voids are present between the foam and sidewall, fill the void with plastic packaging, cardboard etc.

When using for a front bulkhead, cut the foam horizontally three times to use as a dam.
