306,000 lbs. of Xypex Megamix ll were used to rehabilitate the Raccoon Creek Water Treatment Plant in Summerville, GA. An engineering study determined that the superior bonding, chemical durability, and high strength of Megamix ll would completely repair the structure’s deteriorated concrete and bring it up to EPA standards. The rehabilitation option was good economic news; its cost of $ 1.25 million was obviously preferred to the estimated $ 25 million to fully replace the structure.

This 50-year-old WTP was in fact so deteriorated because of years of chemical attack, it was questionable as to whether repair, instead of full replacement, was even possible especially in light of the ever-higher environmental demands. The engineering study was therefore necessary and Xypex Megamix ll was deemed the preferred option. Scheduling was an issue because the communities surrounding this facility (which processes 6 million gallons of water per day) were dependent on its continuous operation. Megamix ll made this possible, facilitating a three-phase construction schedule that enabled reconstruction without interrupting the water treatment process. Megamix ll was used specifically on the flocculation tanks and sedimentation basins. Megamix l and Xypex Concentrate were used on the exposed exterior walls and on the interior surfaces of the filter tanks. Xypex Concentrate and Modified were applied to the vertical surfaces and soffits of the numerous walkways and Xypex FCM 80 was applied to the top surface of walkways separating the individual tanks.

The use of concrete as a design element has always appealed to architects. However, concern over water seepage, efflorescence and rebar corrosion has often held them back. Faced with this issue, Joseph Bellomo Architects used the crystalline waterproofing and protection features of Xypex in an innovative concrete mix on their new LEED Platinum project in Palo Alto, California. A 70% slag concrete mix combined with Xypex Admix was used for the 3600 cubic yards required for the six-story building’s façade.

Joseph Bellomo, principal architect, reported that, “The slag/Xypex combination created the densest, most durable, waterproof concrete that we’ve yet been able to produce. There is no porosity and no signs of efflorescence in the concrete. It is ideal for indoor/outdoor facades, integrated drip edges and tight reinforcement.”

Registered with a LEED certification goal of Platinum this structure, located along California’s central coast at 102 University Avenue in Palo Alto, is expected to provide a sustainable, energy efficient environment – come rain or shine.

Xypex was used to waterproof the concrete in the initial construction phase of the Santo Domingo Metro. Over 100,000 lbs (45,000 kg) of Xypex Admix C-1000 NF was installed in the concrete required by 15 km of tunnel construction.

Based on the successful results of this first application, Xypex Admix C-1000NF and its proprietary crystalline technology has again been specified for the waterproofing and protection of the tunneling in the second line of the metro – estimated at 13 km, and a completion date of mid 2012. The Santo Domingo Metro, part of a National Master Plan to improve transportation and expand infrastructure, is the first subway system in the Dominican Republic and the second in the Caribbean and was prompted by the need to reduce the continually rising road traffic congestion and air pollution in the city.

Xypex Crystalline Technology is well known worldwide for its reliability in waterproofing and protecting below grade concrete from ground water, high water tables and extreme hydrostatic pressure. Such were the concerns of the architects, engineers and contractors responsible for the design and construction of Malaysia’s Ministry of Finance, a landmark government structure in Putrajaya, Malaysia. Xypex Admix C-2000NF (4325 cubic metres) was blended into the concrete required for the raft slab of the single level basement in this structure.

Xypex Admix C-1000 was used to waterproof and protect the below-grade concrete slab and elevator pits of this 28-storey skyscraper. Xypex Concentrate Dry-Pac was then installed in all floor-wall joints followed by a slurry coat application of Xypex Concentrate. Changing the skyline, the Willis Building is the fourth tallest building in London. Its progressive environmental strategy surpasses statutory carbon reduction targets and meets the highest standards for sustainability. Over 15,000 cubic metres of concrete were used in its construction.

Located in the heart of London’s financial district, the Willis Building is the new headquarters of the global insurance broker, Willis Group Holdings. Designed by world-renowned architects Foster + Partners, the building won the New City Architecture Award for its unique architectural form and contribution to the streetscape and skyscape of the City of London. The project is significant in both urban and environmental terms. Most of the material from demolition of the previous building was recycled and crushed for use in the 38-metre-deep foundations.

The Academy of Science in San Francisco, designed by Renzo Piano emphasizes light, fluidity and transparency and incorporates a 2.5 acre Living Roof, recycled and natural materials, and a photovoltaic ‘solar halo’ which provides a minimum of 10% of the structure’s energy requirements. The Academy was designed with superior environmental standards in mind, striving for the highest LEED rating possible: Platinum. The non-toxic and eco-friendly characteristics of Xypex made it the ideal choice for the waterproofing and protection of the 4,000 cu. yds. of concrete used to construct the building’s foundation slab and walls. Over 48,000 lbs. of Xypex C-500 were used on this innovative structure.
