RILEM tubes can be used to assess a substrate's resistance to water absorption, to compare the absorption before and after treatment with a water repellent, and to evaluate the durability of a repellent by periodically measuring absorption. Although widely used by the construction industry, there is currently no industry standard available describing exactly how to perform the test. Small changes in the testing procedure may lead to different results, including how to attach the tube, how to fill it, and at which intervals to perform the readings. Standardization would improve the uniform interpretation of results.
