Mortar Mix

Mortar Mix: What You Need to Know

Mortar mix, also known as masonry mortar or pre-blended mortar, is a specialized bonding material used for bricklaying, block construction, and stonework applications. Designed to provide strong adhesion, flexibility, and durability, mortar mix is available in different PSI strengths and compositions to suit a variety of structural and repair needs. With options for general masonry, high-strength applications, and rapid-setting repairs, these mixes are essential for both new construction and restoration projects.

Types of Mortar Mix and Their Uses:

• PSI-750 (Type N Mortar Mix): A general-purpose mix designed for above-grade, non-load-bearing applications. Commonly used for bricklaying, interior walls, and repair work, this mix provides good bonding strength while allowing slight flexibility to accommodate minor movements in structures.
• PSI-1800 (Type S Mortar Mix): A stronger, more durable mix ideal for load-bearing walls, exterior applications, and below-grade work. It offers higher strength and increased weather resistance, making it suitable for retaining walls, foundation walls, and paving stone installations.
• PSI-3800 (All-Purpose Mortar Mix): A versatile, high-strength mix that provides strong adhesion and durability for general masonry, structural repairs, and tile setting. It is formulated for increased bond strength, ensuring lasting performance in demanding applications.
• PSI-6500 (High-Strength Structural Mortar): A commercial-grade mix used for heavy-duty masonry, reinforcement, and structural repair. It is designed for high-compression strength applications, such as restoring deteriorated mortar joints, setting heavy stone, and reinforcing concrete elements.

Features:

• Fast-Setting Options: Select mortar mixes, such as PSI-6500, are designed to set within 15 to 120 minutes, allowing for quick repairs and reduced downtime on construction projects. These rapid-setting formulations help speed up project timelines, making them ideal for time-sensitive masonry work and emergency repairs.
• Enhanced Bonding Strength: Higher PSI options provide superior adhesion, ensuring masonry structures remain stable and resistant to shifting over time. This increased bond strength prevents cracking and separation, making it a reliable choice for load-bearing walls, foundation repairs, and heavy stone installations.
• Weather & Moisture Resistance: Certain mixes, such as PSI-1800, offer increased durability against freeze-thaw cycles, moisture penetration, and environmental wear. This makes them ideal for exterior walls, retaining structures, and areas exposed to fluctuating weather conditions, ensuring long-term structural stability.

Compliance & Standards:

• ASTM C270 Certified: Meets the industry standard for masonry mortar, ensuring strength, durability, and workability in load-bearing and non-load-bearing applications.
• ASTM C1714 Compliant: Designed for pre-blended mortar mixes, meeting the requirements for structural masonry and repair work in commercial and residential projects.
• Building Code Approved: Suitable for contractors, builders, and DIY projects that require high-strength, code-compliant mortar for long-term structural integrity.
