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

BELOW GRADE INSTALLATION INSTRUCTIONS
EXCAVATION
Install the unit(s) as close as possible to fixtures being serviced.
1.
Width and length of excavation shall be minimum 12" greater
2.
than the tank on all sides.
Depth of excavation shall be 6" deeper than tank bottom.
3.
Set the tank in well-packed crushed aggregate material
4.
approximately 3/4" size rock, or sand, with no fines.
Anchor kit is recommended for installations in high water table conditions to
5.
prevent float out. To be determined by specifying engineer. If necessary,
order optional "Anchor Kit" (see detail right).
