BACKFILLING & FINISHED CONCRETE SLAB
Preparation of sub grade per geotech recommendations.
1.
Stabilize and compact sub grade to 95% proctor.
2.
Fill tank with water before backfilling to prevent float out during piping installation.
3.
Before backfilling and pouring of slab secure cover(s) and riser/s (if necessary) to the unit(s)
4.
Backfill using crushed aggregate material approximately 3/4" size rock, or sand,
5.
with no fines.
6. Place 6" aggregate base under slab. Aggregate should be 3/4" size rock, or sand, with no fines.
7. Thickness of concrete around cover to be determined by specifying engineer. If traffic
loading is required the concrete slab dimensions shown are for guideline
purposes only.
8. Concrete to be 28 day compressive strength to 4000 PSI.
9. NO. 4 rebar ( 1/2") grade 60 steel per ASTM A615: connected with tie wire.
10. Rebar to be 2 1/2" from edge of concrete.
11. Rebar spacing 12" grid. 4" spacing around access openings.
12. All pipe penetrations to be sleeved or have slip connections.
