Mortar Testing

  • We offer Two types of Mortar Testing to better serve your needs.

    • Mortar Testing Report and Formula - This test is commonly used by contractors who need to match mortar types/crushing pressures and compositions for commercial and historic restorations. With this option, you will get the mortar composition testing results and a formula for making the matching mortar type.

    • Mortar Analysis/Color Matching - This test is used by home owners and contractors to make brick mortar repairs quick and easy. We perform many of the same tests for this option, but the formula is not provided nor a report sent. We collect the information from these tests required to match your mortar and apply our proprietary formulas and mortar matching system to get you a perfect mortar color match. From this formula match, we can produce bags of mortar for your project.

Order your mortar analysis and bags of pre-matched tuck point mortars and make your repairs disappear.
