Laticrete Introduces STRATA_MAT XT

Posted on 14 July 2016 by cradmin

Laticrete STRATA_MAT-XTLATICRETE announced the introduction of STRATA_MAT™ XT, a next-generation, high-performance uncoupling membrane designed specifically for ceramic tile and dimension stone installations. STRATA_MAT XT reportedly provides vapor management, eliminates transmission of in-plane substrate cracks of up to 1/8 in., assists with easier floor layout with chalk lines that are easily visible on the surface prior to tile installation and performs all these functions while still providing the requisite support and load distribution for tile and stone covering. At 5/16 in. thick STRATA_MAT XT helps to create an even transition between typical ¼ in. to 3/8 in. thick tile and ¾ in. thick hardwood flooring. This new product also reportedly allows installers to see mortar coverage underneath the mat during installation without having to lift and verify. STRATA_MAT XT comes in 150 ft. rolls measuring 45 in. by 40 ft. and measures 5/16 in. thick.

“Lightweight and easy to carry, STRATA_MAT™ XT is also fast to install with standard tools,” said Sean Boyle, senior director of marketing and product management. “This next generation product has countless applications. For example, it is suitable for interior non-industrial vehicular traffic applications over concrete substrates, and it can also be used to create an even transition between tile and hardwood flooring. The list goes on and on.”

Available for purchase in July 2016, STRATA_MAT XT features Mortar Hydration Vents, which create a mechanical bond between the mat and adhesive mortar and allow the mortar to cure faster. According to the company this provides a stronger bond of tile and permits faster time to grout when using both modified or unmodified mortars—enabling the use of the appropriate mortar for an installation.

Part of the LATICRETE® Lifetime System Warranty, STRATA_MAT XT may be used on almost any substrate including: concrete, mortar beds, oriented strand board, exterior glue plywood, cement backer board, cement terrazzo, resilient flooring, existing tile or stone, gypsum underlayment and light weight concrete.

The U.S. Has Granite, So Why Aren’t We Buying?

Posted on 11 August 2014 by cradmin

GEDSC DIGITAL CAMERAI recently returned from a camping trip in Northern California’s Trinity Alps and was awestruck by the natural beauty of these lands located north of Weaverville and southwest of sprawling, ominous Mt. Shasta. As I hiked up the cliffs overlooking the aptly named Granite Lake, it struck me that the natural forces of the earth could produce such a magnificent material and that human hands and ingenuity could refine it into such an attractive yet practical product like a kitchen countertop.

After the hike, while floating on the lake with a cold beer, I wondered what, if anything, could be produced from the type of granite that surrounded me. Weaverville and the other small communities in the vicinity were born as mining towns during the gold rush, but many other mineral deposits could also be found.

On the drive in, down Highway 3, it was apparent that crushed rock and gravel were dominant. Piles of rocks more than 100 ft. high stretched along the road for miles at a time, and after a short break, there continued several miles more of nothing but quarried, crushed rock.

Upon reflection, I noted the natural formations on the cliffs were mostly cracked and broken. And although some large veins of pure quartz sparkled fantastically in the sunlight, the granite was somewhat dull and less than lustrous. When I returned home, I put my research machine into action, and discovered that my hunch was correct. The granite deposits in the Trinity Alps had experienced tremendous pressure during their formation, and the compression made them unsuitable for use as dimension stone. So, if U.S. granite doesn’t come from here, then from where do we get our slabs?

The United States mines an exceptional amount of dimension granite and other dimension stone. In fact, this country is one of the leading producers of natural stone in the world, but this only makes it more shocking that our dimension stone imports average at about 80 percent of our consumption.

According to the 2014 report from the U.S. Geological Survey (USGS), 2.17 million tons of U.S. dimension stone valued at $460 million was sold or used in the U.S. in 2013. A total of 208 companies produced the stone from 276 quarries in 34 states, and the leading producers were Texas, Indiana and Wisconsin. In addition, the tonnage of dimension stone produced has been increasing each year since at least 2009, when the total was 1.62 million.

Although these numbers seem promising and look good without any comparisons, the $460 million of dimension stone used or sold by U.S. producers is dwarfed by the $1.86 billion in dimension stone imports.

Of the total dimension stone sold or used by U.S. producers in 2013, 41 percent was limestone, 23 percent granite, 15 percent sandstone, 3 percent marble, 2 percent slate and 15 percent miscellaneous. By value, 50 percent of this stone was dressed, and 46 percent of dressed stone was sold in partially squared pieces or slabs.

Looking more specifically at granite, 500,000 tons was produced in the U.S. by 39 companies operating 57 quarries in 15 states, and 80 percent of that was exported. The rest of the granite used in the U.S. was imported from Brazil (42 percent), China (23 percent), India (14 percent) and Italy (13 percent). Even with a median tariff of 3 percent on dimension stone, it still somehow makes more sense to go with the imports rather than with domestically produced stone.

Many environmentalists in the U.S. would agree that this country should be spared from increased mining, which could disrupt natural ecosystems and become an eyesore on the landscape. However, the environmental impact of transporting these slabs from halfway around the world could, arguably, be causing much more damage.

In addition, some reports have stated that some overseas granite operations are funding terrorism, and the granite coming from China is of inferior quality and cannot be used domestically.

So, what is it that makes granite imports so popular?

The leading factor, of course, is price, and following close behind is the fact that we do not have the infrastructure in place to meet such high demand. The United States is the world’s top market for dimension stone. Since the economy recovered, demand for dimension stone has increased not only for construction but also for use in existing structures.

Some people say that U.S. granite just doesn’t exhibit the vibrant and unique color patterns of imported stone, but is this truly the case? While certain colors and patterns are unique to locations overseas, it seems that the United States has slabs of equal or even greater brilliance.

Kurt Swenson, president of one of the largest granite quarries in the U.S., Rock of Ages in Vermont, says that much of the demand for overseas granite is black granite. However, some of this demand is for block granite or decorative granite that is to be etched, which is not typically done on slabs for countertops.

Chuck Monson, president of Dakota Granite, is in agreement with Swenson. He states that the demand for black granite rose when the U.S. decided to use such slabs imported from India to build the Vietnam Memorial. But again, he was referring to granite to be used for monuments and statues rather than countertops.

So, is it simply price that is driving the market for imports? Many U.S. granite producers think so. However, another factor may simply be ignorance by the average consumer. Perhaps an education campaign can bring U.S. production up and help to further stimulate our economy.
