• Below-grade masonry construction and foundation repairs

Frequently Asked Questions

What makes Type S mortar different from Type N? Type S is a high-strength mortar with a higher compressive strength requirement, making it the preferred choice for below-grade applications, heavy structural load-bearing walls, and retaining structures subject to lateral earth pressures.

How much water should I add to an 80 lb bag? Add approximately 5 to 6 pints of clean water per 80 lb bag, mixing until you achieve a uniform, creamy, and workable consistency that holds its shape on a mason's trowel.

Can this mix be used for exterior projects in cold weather? Like all standard cement-based mortars, it should be protected from freezing during the initial 48-hour curing phase and applied in accordance with standard cold-weather masonry guidelines.
