What is Durock?
Industrial Durock (USG brand cement board or high-performance equivalents like Permabase) is a prefabricated building element, composed of a densified Portland cement core with special additives and lightened with pumice, completely wrapped in a woven and polymerized alkali-resistant fiberglass mesh.
This dry lightweight construction system is designed to offer superior structural performance in conditions of extreme humidity, direct contact with water, and exposure to the elements, overcoming the physical limitations of traditional gypsum panels.
Key components of the structural system:
- Portland Cement Core: Provides rigidity, compressive strength, and zero capillary moisture absorption.
- Double-Wrapped Fiberglass Mesh: Reinforces both sides of the panel, providing high flexural and impact resistance.
- Edge Wrap (EdgeTech Technology): Smooth, reinforced longitudinal edges that facilitate joint compound application and prevent crumbling during fastening.
- Structural Quality Metal Framing: Hot-dip galvanized steel studs and tracks (minimum G60 or G90) that support wind and dead loads.
When is it needed?
Plant managers and maintenance superintendents should plan for the installation of Durock systems when the following operational conditions are present:
- Remodeling or expansion of industrial washrooms: Equipment washing areas, sanitization tunnels, or zones with constant use of high-pressure water.
- Deterioration of existing gypsum walls: Presence of bulging, paint peeling, black mold, or loss of cohesion in partition walls exposed to moisture.
- Rehabilitation of corporate facades or industrial warehouses: Need to update the building's exterior image with a lightweight system that does not overload the foundation but resists winds and torrential rains.
- Adaptation of laboratories and quality control areas: Spaces that require constant chemical disinfection and wall washing with sanitizing agents.
- Thermal transition zones: Walls adjacent to cold rooms, freezer chambers, or boiler areas where thermal shock generates constant condensation.
Problems it solves
- Non-conformities in food safety audits (HACCP / FDA): Eliminates the formation of fungi, bacteria, and the detachment of gypsum or paint particles that contaminate food and pharmaceutical production lines.
- Recurring costs for wall maintenance: Avoids having to repair and paint conventional drywall every 6 months due to moisture damage.
- Plant shutdowns due to heavy civil work: Durock installation is clean, fast, and does not require prolonged curing or the hauling of wet materials (sand, gravel, cement) typical of block and brick.
- Risk of structural collapse due to moisture: In shower areas, dining rooms, or staff changing rooms, Durock prevents water infiltration from oxidizing metal studs and collapsing the wall.
Benefits for your plant
- Regulatory Compliance: Facilitates plant certification under international standards (FSSC 22000, SQF, ISO 14001) thanks to its fungicidal and water-repellent properties.
- Reduced Execution Time: Up to a 60% reduction in construction times compared to traditional masonry walls.
- Thermal and Acoustic Insulation: By integrating with fiberglass or mineral wool batts in the framing cavity, acoustic reductions of up to 50 dB and a significant decrease in heat transfer are achieved.
- Return on Investment (ROI): With a projected lifespan exceeding 25 years under severe moisture conditions, the total cost of ownership (TCO) is drastically lower than that of gypsum or plastered block systems.
Applications and industries that use it
- Food and Beverage Industry: Pallet washrooms, bottling areas, loading docks with condensation, and industrial kitchens.
- Automotive and Metalworking Industry: Exterior facades of plant offices, paint booths (wet areas), and metrological testing laboratories.
- Pharmaceutical and Chemical Sector: Partition walls in cleanrooms that receive sanitary-grade epoxy coatings.
- Commercial and Service Buildings: Facades of distribution centers (CEDIS), restroom areas, and operational staff changing rooms in plants with high worker density.

Materials and technologies
At SINE México we use only industrial specification materials to guarantee the longevity of the system:
- Cement Boards: We primarily use USG Durock® Brand Cement Board o Permabase®, strictly complying with the standard ASTM C1325.
- Mechanical Fasteners: DS type screws (with galvanic corrosion-resistant coating) of 1-1/4" for metal fastening, preventing future rust stains.
- Joint Mortars (Basecoat): Formulations rich in acrylic polymers (such as Sika, MAPEI, or USG Basecoat) that ensure joint flexibility and prevent cracks due to structural movements.
- Vapor and Wind Barriers: Tyvek CommercialWrap type membranes to allow the wall to breathe outwards while preventing liquid water entry.
Applicable Regulations and Standards
Our Durock installations are governed by international and national standards to ensure maximum structural quality:
- ASTM C1325: Standard Specification for Fiber-Reinforced Cement Panels.
- ASTM D3273: Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings.
- ASTM E84: Standard Test Method for Surface Burning Characteristics of Building Materials (Flame Spread Index = 0, Smoke Developed Index = 0).
- NOM-008-ASEA-2019 / NOM-001-SEDE: Structural safety criteria and concealed electrical conduits in light construction systems.
Our work process (SINE)
- Technical Diagnosis: On-site visit (Torreón, Saltillo, Piedras Negras) to evaluate wind conditions, humidity, wall height, and load requirements.
- Engineering and Modulation: Calculation of steel gauges, post spacing, and panel modulation to minimize material waste.
- Structural Frame Installation: Assembly of the galvanized steel structure, precise plumbing using a precision laser level, and placement of structural anchors.
- Installation of Utilities and Insulation: Laying of conduit pipes, wiring, and insertion of fiberglass batts for thermal and acoustic insulation.
- Durock Panel Fastening: Placement of cement boards with staggered joints, leaving a 3 mm gap between boards to allow for thermal expansion.
- Joint Treatment and Caulking: Application of fiberglass tape and a double layer of Basecoat mortar. Perimeter sealing with high-performance polyurethane.
- Finish Application and Delivery: Application of final coating (textured, epoxy paint, or tile) and delivery of the work with complete area cleanup.
Common errors when hiring / installing
- Using conventional drywall screws (black): Durock's cement rapidly corrodes common carbon steel, causing panels to collapse. SINE exclusively uses galvanized DS-type screws.
- Omitting the gap between panels: Installing boards flush (completely touching) causes joints to pop and crack the finish when they expand due to heat.
- Using gypsum all-purpose compound (Redimix): Gypsum absorbs water and disintegrates in humid areas. Durock joint treatment must be 100% cementitious.
- Installing on light-gauge studs (Gauge 26): The self-weight of the cement panel and external wind pressure require structural gauge frames (Gauge 22 to 18).
Factors determining cost
The cost per square meter of an industrial Durock system varies depending on:
- Work height: Double-height walls or exterior facades requiring structural scaffolding or lifting platforms (Genie/JLG).
- Frame gauge and modulation: Designs requiring 18-gauge studs spaced every 30.5 cm due to high wind loads or large-format tile weight.
- Environmental conditions of the area: Installation logistics in active process areas requiring dust containment or night work.
- Geographic location: Projects in Torreón, Saltillo, Piedras Negras, or anywhere in the northeast of the country.
