The Treadstone Elite sound attenuation membrane and Elevation DM2 exterior drainage mat are identical products, differentiated only by their installation orientation. This innovative design delivers exceptional performance in both applications while simplifying inventory, reducing costs, and ensuring consistent quality across diverse construction needs. PRODUCT OVERVIEW Core Technology: High-performance dimpled membrane with integrated geotextile fabric. Material: 98% post-consumer recycled UV-stable polyolefin construction. Dual Application: Sound attenuation (dimple side up) / Drainage management (fabric side up) SOUND ATTENUATION APPLICATION: TREADSTONE ELITE Performance Standards Treadstone Elite addresses critical acoustic metrics, including IIC (Impact Insulation Class), HIIC (High-frequency Impact Insulation Class), and STC (Sound Transmission Class) ratings, which measure a material’s ability to reduce sound transmission between dwelling units. Technical Specifications - Sound Control • Installation: Dimple side up configuration • Primary Function: Impact sound isolation between floors • Application: Multi-family residential, commercial, and hospitality projects • Target Performance : IIC ratings typically range from 40-45 for basic construction, with quality underlayments achieving IIC 50+ to meet building code requirements. HIIC measurements focus on 400Hz to 3,150Hz frequencies that resemble clicks or taps - the exact sounds most effectively reduced by quality flooring underlayments. Sound Transmission Science The dimpled structure creates an effective air gap that disrupts the transmission of impact sound. When impacts occur on the floor above, the dimples compress and recover, TECHNICAL BULLETIN Treadstone Elite / Elevation DM2: One Product, Two Critical Applications absorbing kinetic energy that would otherwise transmit as vibrations through the floor/ceiling assembly. The fabric layer provides additional damping while maintaining structural integrity under foot traffic loads. DRAINAGE APPLICATION: ELEVATION DM2 Performance Standards Elevation DM2 addresses critical issues in elevated concrete applications, where traditional waterproof membranes can trap moisture within slabs. In warm climates, trapped water leaches unreacted salts, causing efflorescence, whereas in cold temperatures, freeze-thaw cycles lead to cracking and spalling. Technical Specifications - Drainage Control • Installation: Fabric side up configuration • Primary Function: Creates a drainage layer between the concrete and the waterproofing membrane, allowing water permeation and elimination • Application: Multi-family residential, commercial, and hospitality projects • System Integration : Used with Treadstone S60 waterproofing membrane and the Elevation componentry • Thickness: 3/8” profile - one of the thinnest drainage membranes on the market • Installation Advantage: Minimal thickness eliminates the need for door threshold reframing • Performance: Results in a concrete slab sitting atop pillars of a drainage mat, allowing water to permeate the slab, enter the drainage mat, and flow to the drip edge Drainage Science The dimpled core provides high-flow water collection and conveyance while the filter fabric retains soil particles and concrete fines, allowing filtered water to pass into the drainage core. This prevents clogging while maintaining long-term drainage performance. The system effectively relieves hydrostatic pressure, extending the lifespan of the waterproofing membrane. Engineering Excellence Through Innovation Dimples up for Sound Attenuation. Fleece up for Drainage. formulatedmaterials.com DUAL-PURPOSE ENGINEERING ADVANTAGES Material Optimization The identical core technology ensures consistent quality and performance across both applications. The dimpled structure’s versatility lies in its elegant simplicity - polypropylene or HDPE sheets molded into raised dimples with varying heights, thicknesses, and compressive strengths to match application requirements. Installation Efficiency • Sound Control: Dimples face upward to create impact-absorbing air cushions • Drainage: Fabric faces upward to filter debris while dimples channel water flow • Universal Installation: Same fastening methods and installation techniques • Weather Independence: Installation can proceed immediately after form removal in any weather conditions Economic Benefits • Inventory Simplification: One product serves dual purposes • Reduced Training: Single installation methodology with orientation variation • Cost Efficiency: Eliminates the need for separate product lines • Quality Assurance: Factory-controlled manufacturing ensures consistent performance PERFORMANCE VALIDATION Sound Attenuation Testing Laboratory testing follows ASTM E492 protocols, using standardized tapping machines with steel-faced hammers that generate impacts between 125 Hz and 4,000 Hz. Results compare transmission through test assemblies to reference constructions, determining IIC ratings that directly correlate to real-world noise reduction performance. Drainage Performance Testing High-flow capacity testing validates water collection and conveyance rates under various loading conditions. The DM2 mat has been tested to pass greater than 20 gallons per hour per square inch, demonstrating exceptional drainage performance that far exceeds typical project requirements. Compressive strength testing ensures the integrity of dimples under backfill and structural loads, while filtration testing confirms the effectiveness of geotextiles in preventing system clogging. SYSTEM INTEGRATION Sound Control Systems Treadstone Elite integrates seamlessly with flooring assemblies, providing critical impact sound isolation that helps achieve International Building Code requirements of STC 50 for multi-family construction - the threshold where noise complaints drastically reduce and occupant satisfaction increases. Drainage Systems Elevation DM2 provides a comprehensive moisture management solution when combined with Treadstone S60 membrane, enabling concrete slabs to “breathe” from both top and bottom, thereby preventing efflorescence and freeze-thaw damage. ENVIRONMENTAL & SUSTAINABILITY BENEFITS Material Composition • UV-stable polyolefin 98% post-consumer recycled construction ensures long-term durability • HDPE materials are environmentally safe and won’t leach harmful chemicals into the surrounding environments • Expected service life exceeds 50 years in both applications Performance Longevity Dimpled membranes bridge foundation shifts and cracks, maintaining protection integrity throughout a building’s lifecycle. The robust construction resists damage during installation and backfilling operations. CONCLUSION The Treadstone Elite / Elevation DM2 represents a paradigm shift in construction material efficiency. By engineering a single product that excels in both acoustic control and drainage management applications, Formulated Materials delivers unmatched versatility without compromising performance. The orientation-dependent functionality demonstrates sophisticated materials engineering that addresses real-world construction challenges while simplifying procurement, installation, and maintenance processes. This dual-purpose approach reflects Formulated Materials’ commitment to innovation, efficiency, and superior performance across a wide range of construction applications. Whether controlling sound transmission in multi-family housing or managing moisture in elevated concrete structures, this single product delivers the specialized performance characteristics required for each critical application.
