1.04 DESIGN CRITERIA
A.
Waterproofing system shall be complete and consist of all
liquid membranes, protection boards, drainage panels,
tapes, and other material required for the system to be
watertight.
System shown on Drawings and specified
herein is based on Grace Construction Products materials.
Other manufacturers listed are acceptable if they have a
complete system that meets the performance requirements
of this specification. Regardless of manufacturer used,
the Contractor is responsible for providing a complete
system and shall discuss with manufacturer prior to bid.
B.
The Grace polyethylene membrane (Preprufe) used on the
underside of slabs may not require the use of a mud mat.
If other systems are used, the use of a mud mat is

required.
It is also to be used for blind side
applications where lagging or formwork is not to be
removed. The Carlisle butyl rubber membrane (.120 Butyl)
requires protection board on each side as a minimum. Mud
mat, protection board, and any additional detailing
required by the Architect/Engineer of Record to provide
for the proper installation of the membrane shall be at
no cost to the Authority.

areas which can be covered that same day.
All
joints are to be done first by applying primer only
at the joints and installing the coverstrips.
2.
After primer is tack free, apply rubberized asphalt
membrane, lapping edge seams a minimum of 3", and
end seams a minimum of 4"; apply wall membrane to
form lap with slab membrane and up walls to
