Employing decades of experience delivering tailor-made
solutions for projects in developed and developing econ-
omies, we work with our customers around the world to
build sustainable, industry-leading infrastructure that will
enable our communities to thrive today and well into the
future. This year, we participated in a number of high-
scale infrastructure projects, including Panama’s Coast-
al Beltway, one of the most important transportation
initiatives in the nation’s capital. To satisfy the project’s
demanding requirements, we designed and delivered
nearly 130,000 cubic meters of specialty added-re-
sistance concrete for maritime use in the construction
of transversal and longitudinal beams, foundations, and
jetties for this new phase of the beltway. In Israel, we
supplied our structural expertise, along with approxi-
mately 100,000 cubic meters of specialty ready-mix
concrete, to satisfy the engineering complexities of the
first stage of Israel’s new national railway. In England, we
provided our custom-made ready-mix concrete, coupled
with our industry-leading logistical expertise, for one
of the 80-meter deep shafts of the Thames Water Lee
Tunnel in Greater London. To meet the project’s challeng-
ing material requirements, three cranes delivered 11,000
cubic meters of ready-mix concrete over 29 uninter-
rupted days, one of the longest continual slip form pours
recorded in Europe.
Delivering industry-leading
building solutions
Concrete vs. asphalt pavement
Concrete pavement solutions provide significant advantages over asphalt; its
excellent surface finish, superior durability, and low total cost over the full life
cycle make it the material of choice.
Concrete roads can be designed for 50
years or more, and they last around
three times longer than asphalt roads
before a first major rehabilitation is
required.
Including the full lifecycle of the proj-
ect, concrete has a significantly lower
total cost versus asphalt, despite its
slightly higher initial cost.
Cities are warmer than their surroundings,
which in summer leads to discomfort,
medical conditions, and higher air condi-
tioning use. Light-colored surfaces with
high reflectivity, such as concrete, reduce
this so-called urban “heat island” effect.
On the rigid surface of a concrete
pavement, wheels do not sink in as
much as they do on flexible (i.e., asphalt)
pavements. This effect, called deflection,
is invisible to the naked eye, but has a no-
ticeable impact on vehicle fuel efficiency.

tom-made ready-mix
concrete for one of the
80-meter deep shafts of the
Thames Water Lee Tunnel in
Greater London, England.
