1. Steel Pipe Sleeves: ASTM A 53/A 53M, Type E, Grade B, Schedule 40, zinc coated,
plain ends.
2.2 GROUT
A. Description: Nonshrink; recommended for interior and exterior sealing openings in non-fire-
rated walls or floors.
B. Standard: ASTM C 1107/C 1107M, Grade B, post-hardening and volume-adjusting, dry,
hydraulic-cement grout.
C. Design Mix: 5000-psi, 28-day compressive strength.
D. Packaging: Premixed and factory packaged.
2.3 SILICONE SEALANTS
A. Silicone Sealants: Single-component, silicone-based, neutral-curing elastomeric sealants of
grade indicated below.
1. Grade: Pourable (self-leveling) formulation for openings in floors and other horizontal
surfaces that are not fire rated.
B. Silicone Foams: Multicomponent, silicone-based liquid elastomers that, when mixed, expand
and cure in place to produce a flexible, nonshrinking foam.
PART 3 - EXECUTION
3.1 SLEEVE INSTALLATION FOR NON-FIRE-RATED ELECTRICAL PENETRATIONS
A. Comply with NECA 1.
B. Comply with NEMA VE 2 for cable tray and cable penetrations.
C. Sleeves for Conduits Penetrating Above-Grade Non-Fire-Rated Concrete and Masonry-Unit
Walls:
1. Interior Penetrations of Non-Fire-Rated Walls:
a. Seal annular space between sleeve and raceway or cable, using joint sealant
appropriate for size, depth, and location of joint. Comply with requirements in
Section 079210 "Joint Sealants."
b. Seal space outside of sleeves with mortar or grout. Pack sealing material solidly
between sleeve and wall so no voids remain. Tool exposed surfaces smooth;
protect material while curing.

2. Size pipe sleeves to provide 1/4-inch annular clear space between sleeve and raceway or
cable.
3. Install sleeves for wall penetrations unless core-drilled holes or formed openings are
used. Install sleeves during erection of walls. Cut sleeves to length for mounting flush
with both surfaces of walls. Deburr after cutting.
D. Sleeves for Conduits Penetrating Non-Fire-Rated Gypsum Board Assemblies:
1. Use circular metal sleeves.
2. Seal space outside of sleeves with approved joint compound for gypsum board
assemblies.
E. Roof-Penetration Sleeves: Seal penetration of individual raceways and cables with flexible
boot-type flashing units applied in coordination with roofing work.
F. Aboveground, Exterior-Wall Penetrations: Seal penetrations using steel pipe sleeves. Select
sleeve size to allow for 1-inch (25-mm) annular clear space between pipe and sleeve.
