SPLICING CEMENT
Provide seaming adhesive as recommended by manufacturer to be compatible
with type of liner used.
2.3
PENETRATIONS
Provide manufacturer's standard factory fabricated penetration assemblies.
Make penetration assemblies of the same base material as liner and at least
1.12 mm 45 mils thick.

FILTER FABRIC
**************************************************************************
NOTE: Filter fabric is a useful material to
provide: 1) a better subgrade; 2) a path for water
or gas migration; 3) and a convenient material for
drainage when a double liner system is used. Specify
cloth that retains the soil being protected, yet
that has openings large enough to permit drainage
and prevent clogging. Select the "equivalent
opening sizes" (EOS) and "percent open area" based
on the following criteria:
1. Filter cloth adjacent to granular materials
containing 50 percent or less by weight fines
(materials passing 75 micrometers No. 200sieve):
a. The 85 percent size of the soil, divided by the
nearest opening size of EOS sieve (nearest U.S.
Standard Sieve) is equal to or greater than one.
