What are RILEM Tubes?
WHAT ARE THEY, & HOW ARE THEY USED?
Plastic or glass tubes that are lined up vertically to the dry masonry surface, the other end of the tube is attached to the masonry surface using a putty. Once attached, water is poured into the open end of the tube, and using the measurements on the side of the tube and a timer, you can measure how quickly a masonry surface can absorb water. RILEM tubes have been proven time and time again to be one of, if not the most reliable test for testing how much water is absorbed by a wall, and is used throughout the industry.
Using RILEM tube tests, you can test the absorptivity of a particular wall to determine if certain products can be used on it, or see if there is a water drainage issue in the wall system if the water is drained exceptionally fast.
