Do I need a concrete pad surrounding
the manholes?

 

 

 

Schier's Great Basin Grease Interecptors can all be Traffic Rated.
Our most popular outdoor models come standard with H-20 Traffic
Rated Covers. Although the covers and body are traffic rated, to
achieve the H-20 Traffic Rating the finished installation must have
a 8" thick concrete pad poured around the manhole cover(s).

 

 

If the interceptor will not be installed in a traffic area, and 8"
concrete pad is not required. However, we do recommend that
the interceptor tops are surrounded with a 4" pedestrian pad.
Pavers, decking, or other suitable hardscape materials may
be used to build a stable solid platform surrounding the
grease interceptors.
