Q: How extensive are MezgerStone's Lueders Limestone reserves?
A: MezgerStone's Lueders Limestone is virtually unlimited as we are only quarrying on approximately 15% of company owned acreage. Geologists estimate more than 100 years of reserves, based on current extraction methods. The reserves are vast, but the consistency of the stone is just as important. Whether a project is large and will require several truckloads of stone or if an addition requires new stone to match up to old stone, the grade and color selected will remain within a reasonably acceptable range. This is not true of some other natural building stones.
Q: What colors are available for MezgerStone blocks and slabs?
A: MezgerStone blocks and slabs are available in a full range of naturally beautiful colors, including Frisco Buff and Avoca Charcoal. Mezger can also provide Cordova Cream, Texas Cream and Texas Shellstone.
Q: What Mezger Stone grades are available?
A: MezgerStone offers select, standard, rustic, and old gothic grading. The structural soundness of each of the grades is essentially identical.
Q: What is the weight of MezgerStone Lueders Limestone?
A: MezgerStone Lueders weighs 144 lb./per cubic ft.
Q: What is the compressive strength of MezgerStone Lueders?
A: The compressive strength is +7,000 PSI minimum (ASTM C170).
Q: What is the moisture absorption of MezgerStone Lueders?
A: Limestone is typically put into three levels of density. Medium Density Limestone has maximum 7% moisture absorption rate. Currently, Mezger Lueders products are running at around 5.47%, which means it has higher density.
Q: How should you clean Mezger Stone products?
A: The most successful method is pressure cleaning at no more than 1,200 PSI. Keep the nozzle a minimum of 1' away and use a fan tip nozzle approximately 12" wide.
Q: Should you dampproof Lueders?
A: Dampproofing should be applied on all unexposed areas at grade up to 12". Below grade total stone must be dampproofed. An ideal
dampproofing material resists both positive and negative hydrostatic pressure.
Q: Does MezgerStone Lueders need to be sealed?
A: While we do not recommend sealing because of the potential for staining, it is best to consult with your engineer.
Q: What types of anchors should be used for MezgerStone products?
A: All anchors should be stainless steel or other non-corrosive. Consult your engineer for anchor type guidance.
Q: What selection size do you offer for panels?
A: For most purposes, 3" or thicker. 2" needs to have special design considerations for the anchoring systems.
Q: What is the SRI (solar reflective index) of MezgerStone Lueders?
A: SRI measures the ability of a constructed surface to reflect solar heat. Designing with high-SRI materials like Mezger Stone products is
important because it can reduce the “heat island effect” commonly associated with urban areas. Mezger's Luders' SRI ratings make it
eligible for LEED 2009 and LEED v4 SRI related points for non-roof applications.
Q: Can MezgerStone Lueders be load-bearing?
A: Yes, as solid columns, self-supporting headers, etc
Q: Can Lueders be repaired with epoxy?
A: Yes, epoxy is used in fabrication as well.
Q: What is the minimum thickness of a MezgerStone Lueders veneer panel?
A: Typical panels are 2". However, thinner veneer is available as engineered.
Q: What is the price per square foot for veneers, pavers, etc.?
A: We sell directly to contractors, builders, masons.etc. Contact your MezgerStone Rep for more details on pricing.
