Mortar Testing/Mortar Analysis/Mortar Matching Services

AMR Labs

AMR Labs is a mortar testing lab providing certified mortar analysis and mortar matching services for all types of mortar, and producing quality masonry repair products and custom mortars.

We have been testing and matching mortars and manufacturing custom bags of mortar for about 20 years with dedication to quality and accuracy. Our mortar analysis services provide timely and accurate results in a clear mortar testing report, and our analysis reports are commonly used and accepted by engineers, architects, and historic preservation organizations across the country.

In addition to providing quality mortar analysis and mortar matching service, we provide these services at affordable prices. Send us a sample and let us show you what we can do for you.

Mortar Analysis Testing/Matching - AMR Labs

AMR Labs is dedicated to providing quality brick and mortar repair products and services. Among these Services, we offer mortar analysis and mortar testing. These are part of our mortar matching services.

Matching the mortars type and crushing pressure are vital for several reasons. The most important reason is that improper mortar will not bond to the original mortar in the joints correctly. If the mortar is too hard, it will deflect and often causes damage to the bricks. If the mortar is too soft, it tends to crumble or deteriorate and is often unable to carry the weight of the brick. Both of these, allow recracking and can cause additional damage or danger of falling brick or walls.

Mortar Matching

Mortar matching is achieved through a number of tests of samples from your mortar. The first test in our mortar analysis is a crushing pressure test to determine the mortar type. Different mortar types will crush at higher pressures. At this point, your crushed mortar sample is washed through a hydrochloric test from which we derive various details about your mortar including the color and gradation of the sand used. Only after we have obtained all of these details about your mortar, can we even begin to match the color of your mortar.

Matching Mortar Color

There are many masonry products available on the market for new construction, and many companies who try to use them for repair. This simply cannot work. These products come in grey and white and require full package consumption at time of use to achieve the labeled mortar type. When small portions of these bags are used to blend a matching mortar color, there is no way to know how much of the Portland or lime that make the mix are being used. This makes the resulting mortar type unknown. This is why we mix from the base units to create a matching mortar. It is the only way to know what type of mortar and crushing pressure is being created.

With this starting point, we match the grey tone of your mortar to our color charts, and begin adjusting pigments as needed.

After, your mortar color is matched, AMR Labs can produce custom bags of pre-matched brick repair mortar for your brick repair project.

We have put together many brick repair training tools to help you complete the brick repairs around your home. Among these are "The Brick Repair Guide" and various brick and mortar repair training videos.

We offer our mortar testing and matching services across the country. To learn more visit our masonry repair products pages.

 

Mortar Testing Services/Mortar Composition Matching - AMR Labs

  • Mortar Testing -This mortar analysis analyzes the compressive strength of mortar, the mortar composition, mortar type, the sand gradation, and produces a mortar formula for matching the mortar composition and type of the existing mortar sample being tested or to analyze and compare two samples of mortar to determine if they are the same. This mortar analysis includes compressive strength testing, hydrochloric testing or acid digestion of mortar, magnified examination, weight loss, and sand analysis. A cleaned sample of the original sand is returned to you with the mortar testing report. This test is also used to determine if the old mortar is a historic mortar or rather contains historic lime.
  • Mortar Matching - In this mortar analysis, we analyze the composition of mortar samples, compressive strength, and color and produce a mortar formula for matching the existing mortar color and composition. This includes an analysis of the original sand.
  • Masonry Unit Testing - This analysis is designed to test the crushing pressure or compressive strength of mortar, brick, stone, block, or tile, and is used to analyze and determine if the mortar used is a good mortar for the masonry units or to determine what type of mortar should be used with the units. A good mortar is slightly softer than the brick or stone it is used to install to prevent damage to the masonry unit.
