Mortar Testing/Mortar Analysis/Mortar Matching Services

Brick Repair

There are three basic parts to brick repair services. These are removing damaged mortar, mortar matching, and replacing mortar.

Brick Repair Services

Brick repair or masonry repair are also known as tuck pointing or repointing mortar cracks, and require matching the composition and color of the existing mortar to make the brick repairs blend into the walls.

Since repointing brick mortar cracks requires a matching mortar, it is important to understand the difference between matching mortar color and matching mortar.

It is possible to match mortar color without matching the composition of the mortar, but this has a variety of problems. This mismatched mortar repair will age different, have different crushing pressure/compressive strength, and tend to pop loose or break off brick faces. These can all be avoided by matching the composition of the mortar before matching the mortar color for any brick repair mortar.

We can provide both forms of mortar matching for your brick repair/tuck pointing repairs, and provide some onsite services in our local area including Dallas/Fort Worth/Granbury Texas areas.

We also produce custom brick repair mortar for repointing mortar cracks.

How long does mortar matching take before brick repair?

Your mortar testing report and a cleaned sample of the original sand will be shipped to you within 5-10 business days.
Some delays may occur with large orders or volume of orders being processed.

Most orders are processed within 1-2 days, and take 1-3 days shipping.


Acquiring A Mortar Sample

Use a hammer and chisel to remove the samples of mortar from the corners of the home or directly from one of the cracks.  Then send us the samples with payment or a copy of the receipt for online payments.

Brick Repair - Mortar Matching


Mortar Testing

Mortar Testing
This test follows the astm testing methods for testing hardened mortar samples including historic lime mortars. This is a complete mortar analysis and includes the following mortar testing methods and more.

Crushing pressure analysis of the mortar compressive strength, chemical or acid digestion test of mortar, composition testing of mortar samples, among other combined mortar testing methods.

Through this mortar analysis, we identify and determine if the mortar is a historic mortar containing historic lime, the mortar composition, color and gradation of sand used, ratio of sand and cement binders, and produce a matching mortar formula to the existing mortar. We can also compare samples of mortar tested to confirm if the mortars are of the same composition.

Mortar Matching

Mortar Matching
In this analysis of existing mortar samples, we test the mortar composition, color and graded particles of the sand, pigments, and compressive strength to determine the mortar formula for matching the old mortar.

This mortar formula is then tested, adjusted, and confirmed to match the existing mortar color for a complete mortar match of the formula, color and composition. This test is commonly used by masonry repair contractors and homeowners looking for diy methods of brick repair to make it easy and accurate, and is used for producing custom bags of mortar.

Brick Testing

Masonry Unit Testing
When choosing the right mortar for a masonry structure, or determining if the mortar used is a good mortar, you need to test the crushing pressure or compressive strength of the masonry units or mortar samples.

This would be the brick, block, stone, or tiles. Mortar should be slightly softer than the masonry units being installed to prevent damage to the bricks. This test determines the crushing pressure of masonry units or can test the crushing pressure of the mortar sample. For full details about the mortar, select the mortar testing option above and get a complete mortar testing analysis report.

Mortar Analysis

Quick Mortar Match
Match mortar color fast with the quick mortar match. This test bases the mortar composition on general mortar type formulas and the compressive strength of your existing mortar.

Requires two or more pieces of surface mortar, but crumbled mortar is ok too.
