RILEM Test Procedure

The RILEM test was developed to measure the effectiveness of water repellent admixtures, such as Impede IntraSeal. The procedure consists of adhering a 5 ml open-ended beaker, called a RILEM tube, to the concrete with putty ensuring a watertight seal. The water is allowed 1 hour to penetrate the concrete. After 1 hour, the water level is recorded to determine the amount of water that has penetrated the concrete.
