FOSROC GROUTS
THE BASIS FOR
SUCCESS
There is a wide range of structural grouts available from Fosroc.
That is because we know that each solution needs to be perfectly
matched to its challenge. Our team is on hand to understand the
project requirements and select the right answer.
Stability is the key to structural integrity. Fosroc has all the grout
solutions that you could need to create a total, solid support.
Whatever you are putting in place, we have the product to give it
the best connection and foundation for success.
Through decades of experience, we know that effective grouting
and anchoring relies on more than strength alone. The flow and
workability of Fosrocs Conbextra range ensures that the best
possible contact is achieved for your application, meaning you
will achieve all the strength that you need, exactly where you
need it.
With exceptional flow, stability and strength characteristics, our
grouts provide the best solution for high precision applications,
combined with a wide range of cement and resin based
anchoring systems. They are tested and outperform industry
laid norms and standards. For many years, our grouts have been
supporting some of the worlds most demanding projects, such
as the King Fahad Causeway between Saudi Arabia and Bahrain,
the Paradip Oil Refinery in India and the Emirates Cable Car in
London. Fosroc Conbextra Grouts are chosen for their ability to
deal with dynamic loads, chemical exposure, extremes of heat
and harsh natural exposure, making them the industrys number
one choice in critical load-bearing situations.

WHY GROUT ?
True Grouting is a precision job. That is why Fosroc are firm believers that using
Conbextra proprietary material is the best way to achieve the results you need.

CONSTRUCTIVE SOLUTIONS IN ACTION
Selecting the correct grout requires more than looking at compressive strength. That is why Fosroc provides a wide array of
grouting products and complimentary ancillaries. We design our materials to exhibit best in class properties, always looking
at the critical issues such as material stability, flowability and ease of application, compressive, flexural and tensile strengths.
Perhaps most critically, Fosroc design our grouts to stand the test of time.
Here is a selection of some some of our projects from around the world:
King Fahad Causeway Saudi Arabia
The 25km King Fahad Causeway, linking Bahrain to Saudi Arabia, is used by
over 19 million passengers a year. Reducing maintenance cycles is a key aim of
all designers, this critical piece of infrastructure is no different. This enormous
structure has been supported by Fosrocs Conbextra HF since its construction
began in 1981.
The product was pumped under pressure between the segmental rings of the
precast piles that support the bridge as they were lifted into place. The grout
was selected for its flowability at high temperatures, stability under pumping
pressure and dual shrinkage compensation. The speed of its set allowed rapid
erection of the piles. Conbextra HF has weathered the elements and exposure,
proving Fosroc is the supplier of choice for critical and durable applications.
Paradip Oil Refinery India
Construction at the massive Paradip refinery for the Indian Oil Corporation
presented a challenge to the Fosroc team. The processing units for crude oil
required varying depths in application and base plate sizes were very large. To
add to the difficulty, ambient temperatures during application frequently rose
above 40C. Of course, the grouts also had to exhibit resistance to a number of
very aggressive chemicals and excellent flexural strength and creep resistance.
The team worked to produce special product formulations to meet the applica-
tion procedures ensuring high contact, high strength and crack free grouting
beneath the machines. Our ability to produce bespoke solutions and a variety
of products including Conbextra EP75, Conbextra EP300, Conbextra GP & Con-
bextra BB92 to meet application needs meant Fosroc were the only company
selected to supply the refinerys grouting.
Emirates Airline Cable Car UK
A novel piling technique was used to cast the supporting columns in the brisk
tidal zone of Londons River Thames. The use of Conbextra UW enabled a
very high quality of concrete to be cast even under water. Once the piles were
in place the initial skirt of the tower was set onto them almost immediately,
meaning the early age compressive strength of Conbextra UW was another
critical requirement.
Initially the proposed construction method and programme meant that the
cable car would not be operational until the end of the summer. Fosrocs
Conbextra UW was an integral part of the success of the new innovative piling
technique adopted due to its very high strength and anti-wash out character-
istics. This innovative approach took 6 weeks off the completion time of the
project; ensuring that it finished well ahead of schedule and was in place to
assist in the logistics of staging the London 2012 Olympic Games.
