laboratory testing for grouts Injection Grouts for the Conservation of Architectural Surfaces: Research and Evaluation
A project of the Getty Conservation Institute
 

Half-filled injection columns are used to determine the ability of grouts to pass through a capillary network of varying porous media under the effect of gravitational force. Grout is poured from the top of the half filled column and the time needed to penetrate 50 mm, 100 mm and 150 mm is recorded. Photo: Traci Lucero.
