W.R. GRACE BUILDING
TRAVERTINE, A FORM OF LIMESTONE, IS USED FOR THE GRID PATTERN THAT COVERS THE
SPACE BETWEEN WINDOWS IN THE GRACE BUILDING
TRAVERTINE IS A TERRESTIAL SEDIMENTARY ROCK. COMMONLY USED FOR FAÇADE, WALL
CLADDING, BACKSPLASH AND FLOORING.
THE USE OF TRAVERTINE MAKES THE GRACE BUILDING APPEAR MORE BRIGHTER THAN ITS
SURROUNDING AND THE WHITE COLOR CONTRAST THE DARK WINDOWS

AIR BARRIER SEALANTS, RAIN PENETRATION AND
MOISTURE CONTROL
Use appropriate sealant for the environment in which it is
expected to perform. Consider the environment that it will
perform. Failure to consider these factors may result in
adhesive failure, cohesive failure, craze cracking,
hardening, disintegration, color changes, or other types of
permanent failure.
STONE
VENEER/PANELS ARE
STRONG AND
DURABLE BUT THEIR
WEAK POINT ARE THE
JOINTS – IT NEEDS TO
BE SEALED SO THAT
WHEN WATER WONT
SIP THROUGH OR THE
WATER CANNOT
DAMAGE IT
Each project requires its own careful sealant consideration
and application.

Air Barriers & Sealants
Precast Concrete Panels
Precast Concrete Panel - One-Stage Joints
Precast Concrete Panel - Two-Stage Joints
Air Barriers & Sealants
A one-stage joint in a
precast panel wall
system. In the socalled face seal
approach, a single line
of defense is
employed against both
rain penetration and
air leakage.
A two-stage joint in a
precast panel. The outer
rain seal serves to
control water leakage
due to kinetic energy.
Any rainwater that does
penetrate the rain barrier
drains to the outside,
before it is able to reach
the air seal.

Attachment Systems & Fire Safety
Weld Plates
Rebar and Grout
The most common method of attachment of
Used typically with slabs, reinforcing
precast members is by use of steel weld
plates. Typically, the precast members have
embedded plates that can be used as welding
surfaces for loose connecting plates or
angles.
bars are spliced into slabs and grouted

Precast Concrete Panels
Case Study:
Jubilee Church
Architect: Richard Meier & Partners
Design Team: Richard Meier, FAIA, John
Eisler, Matteo Pericoli, Alfonso
D’Onofrio
The church has three curved walls
resembling of a ship's sails, as it symbolizes
"the ship in which the people of God sails."
The church has large glass surfaces that
guarantee a generous flow of natural light,
located both at the top and at the main and
back facades.
In order to preserve the whiteness of the building, the company Italcementi developed a
new cement containing titanium dioxide, called TX Millennium, which ensures the
whiteness of the concrete, despite the pollution, rain and weather effects.
TX Millennium cement is formulated with photo-catalytic properties to deliver selfcleaning power. As a result, organic pollutants that settle on the surface of the concrete are
decomposed into oxygen, water, and carbon dioxide.

Case Study:
Jubilee Church
The outer sail is composed of 78 segments, the intermediate of 104 and the
inner, which reaches 26 meters, of 176 segments.
The builder had to invent a mechanism to manipulate the pieces and put them in
place.

Precast Concrete Panels
Architect: Gordon Bunshaft of Skidmore, Owings, & Merrill
Location: New Haven, Connecticut
Client: Yale University
Project Area: 125,262 square feet
Project Year: Completed in 1963

Beinecke Rare Book and Manuscript Library
Precast Concrete Panels
Made of Vermont marble and granite, bronze and glass, the
exterior gives the illusion that the building is completely solid
when viewed from the outside.

Yale University’s Beinecke Rare Book and Manuscript Library
is the largest building in the world dedicated to the containment
and preservation of rare books, manuscripts, and documents.

Precast Concrete Panels
Rain Penetration & Moisture Control
A rainscreen is the first line of defence against
wind-driven rain, and as such is subjected to all
forces leading to rain penetration through its
openings and imperfections.

Moisture Protection
The most common moisture protection
system used with precast concrete wall
systems is a barrier system incorporating
an adequate joint seal. In some cases
where additional moisture protection is
needed, the application of a sealer or a
concrete coating is also used. Sealers can
be either clear or pigmented if used as an
enhancement of the precast appearance.
Film-forming coatings usually offer a higher
level of performance but will have a
significant impact on the appearance of the
precast concrete unit.
The precast concrete panel should also be
designed to provide the appropriate level
of durability for the planned exposure.
Durability can be improved by specifying
minimum compressive strengths,
maximum water to cement ratios, and an
appropriate range of entrained air.
