FIVE IMPORTANT
    BUILDING CERTIFICATIONS

    Like any purchase, the construction world has no lack of product choice and selection. Finding the right product for your project can be a
    challenging process, especially if you are dealing with niche markets in uncharted territories.

    Certifications can help decision-makers easily identify potential products as marks of approval indicate that it has undergone lab testing
    and accreditation. This eliminates skepticism and assures customers that the product performs well and is reliable. Here are the five
    important building certifications that are used around the globe.

system that could guarantee lasting protection of their
building, not only to safeguard their reputation but to
also please their upscale residents. As the building was
an innovative mix of retail, office and residential space,
it included business tenants and residential buyers who
paid up to $5 million CDN for their home.

Lafarge was the concrete provider selected for the
project and they were consulted on methods to optimize
the performance of the concrete. Having worked
with Kryton on many projects both locally and abroad,
they suggested integral crystalline technology as a
solution. Integral crystalline waterproofing replaces
external membranes and coatings by transforming the
entire concrete mass into a waterproof barrier that
cannot be punctured, damaged or worn away. Lafarge
has had tremendous success over the years using
Kryton’s Krystol Internal Membrane (KIM) admixture to
waterproof below grade foundations, pits, retaining walls
and containment tanks but the project collaborators had
an unconventional application in mind.

With a prestigious designer on board, the developers felt
that preserving the exterior look of the building was a
priority. They decided to use Kryton’s KIM admixture for
the above grade areas of the building, as the unfinished
architectural concrete was the unique design finish
dictated by Foster and Partners. As Vancouver sees
heavy rainfalls for over seven months of the year, the
building had to face these elements for its lifetime. Unlike
similar waterproofing systems, Krystol technology is
effective under hydrostatic pressure, allowing it to protect
against rain and other weathering elements. Lafarge
used over 2,500 meters (8,200 feet) of their Chronolia™
concrete treated with approximately 13,440 kilograms
(29,630 pounds) of KIM admixture.

Chronolia™ is Lafarge’s high-performing ready-mix
concrete that accelerates strength gain. Together with
the KIM admixture, there is no question that the concrete
was a premium value added mix. At first glance, the
investment in the mix seemed exorbitant. But upon
closer examination, both value added products allowed
for greater return on time and performance savings.
KIM is packaged in pulpable bags which are added to
the concrete directly at time of mixing. Once cured, it
outperforms coatings, sealers and external membranes
and eliminates sub-trades and the time, scheduling,
storage, coordination and all other associated costs
linked to monitoring them. With the use of KIM alone,
projects typically see reduced waterproofing costs by

     IN THE UNITED STATES


     In the United States, we are still seeing the effects of the economic crisis. While there has been a dramatic reduction of high-
     rise construction projects, the outlooks remain positive as the economy has grown for five consecutive quarters. In fact, the
     Portland Cement Association had 1.4% growth in 201 and expects 4% growth in 2012.
                                                              1

     With only 37% of the federal stimulus money committed to projects so far, the country should benefit from short term growth
     on projects such as healthcare, high speed rail, infrastructure, schools, bridges and dams.

     Further economic growth for the region is bolstered with private funding. With credit still tight, private investors are seeking
     deals in depressed markets. For the last forty years, Kryton has been waterproofing concrete throughout the United States on
     projects that are dry till this day. As infrastructure continues to be an area of focus in the coming years, Kryton looks forward
     to strengthening their position as a key player.

              The Marina Bay Sands, Singapore, sought a single waterproofing solution that
              could protect the massive foundation that includes multi-levels of retail space,
              a casino, exhibition centre, parking, tunnels and more. Complicating matters
              was the fact that the project was built on reclaimed land and surrounded by
              seawater. The designs called for Kryton. Our crystalline technology protects
              concrete—permanently. And our comprehensive system shaves weeks off
              construction schedules and cuts waterproofing costs up to 40%.

As the building was an innovative mix of retail, office and residential space, it included business tenants and residential buyers who paid up to $5 million CDN for their home. Lafarge was the concrete provider selected for the project and they were consulted on methods to optimize the performance of the concrete. Having worked with Kryton on many projects both locally and abroad, they suggested integral crystalline technology as a solution. Integral crystalline waterproofing replaces external membranes and coatings by transforming the entire concrete mass into a waterproof barrier that cannot be punctured, damaged or worn away. Lafarge has had tremendous success over the years using Kryton’s Krystol Internal Membrane (KIM) admixture to waterproof below grade foundations, pits, retaining walls and containment tanks but the project collaborators had an unconventional application in mind. With a prestigious designer on board, the developers felt that preserving the exterior look of the building was a priority. They decided to use Kryton’s KIM admixture for the above grade areas of the building, as the unfinished architectural concrete was the unique design finish dictated by Foster and Partners. As Vancouver sees heavy rainfalls for over seven months of the year, the building had to face these elements for its lifetime. Unlike similar waterproofing systems, Krystol technology is effective under hydrostatic pressure, allowing it to protect against rain and other weathering elements. Lafarge used over 2,500 meters (8,200 feet) of their Chronolia™ concrete treated with approximately 13,440 kilograms (29,630 pounds) of KIM admixture. Chronolia™ is Lafarge’s high-performing ready-mix concrete that accelerates strength gain. Together with the KIM admixture, there is no question that the concrete was a premium value added mix. At first glance, the investment in the mix seemed exorbitant. But upon closer examination, both value added products allowed for greater return on time and performance savings. KIM is packaged in pulpable bags which are added to the concrete directly at time of mixing. Once cured, it outperforms coatings, sealers and external membranes and eliminates sub-trades and the time, scheduling, storage, coordination and all other associated costs linked to monitoring them. With the use of KIM alone, projects typically see reduced waterproofing costs by Jameson House in Downtown Vancouver’s Heritage District marks the first North American residential project by renowned Foster and Partners.

The disadvantages include limited crack resistance, requiring access space to apply and requiring proper surface preparation, making surface coating systems unsuitable for shotcrete applications. Sheet membranes are flexible sheets that are adhered to the wall and then sealed at the seams. This method has excellent crack-bridging ability but has similar limitation to coatings when used with cast-in-place concrete. Shotcrete applications would require the membranes to be hung on the back form, giving a high potential for seam failure and penetrations that would compromise the system.

The self-sealing process is a phenomenon that allows the concrete to seal its own cracks with no external repairing systems. Water is the contributing agent that can set in motion this process. However, new research shows that admixtures have proven to be able to accelerate and improve the self-sealing abilities of concrete.

  • 14. KRYTON IN THE UNITED STATES In the United States, we are still seeing the effects of the economic crisis. While there has been a dramatic reduction of high- rise construction projects, the outlooks remain positive as the economy has grown for five consecutive quarters. In fact, the Portland Cement Association had 1.4% growth in 201 and expects 4% growth in 2012. 1 With only 37% of the federal stimulus money committed to projects so far, the country should benefit from short term growth on projects such as healthcare, high speed rail, infrastructure, schools, bridges and dams. Further economic growth for the region is bolstered with private funding. With credit still tight, private investors are seeking deals in depressed markets. For the last forty years, Kryton has been waterproofing concrete throughout the United States on projects that are dry till this day. As infrastructure continues to be an area of focus in the coming years, Kryton looks forward to strengthening their position as a key player. 1. Clos de la Tech Wine Caves 2.
