A flatjack is a thin envelop-like hydraulic device used for testing in-situ masonry to determine its deformability properties. Typically, to flatjacks (one above the other) are inserted into the masonry joints of the designated wall. The flatjacks are typically installed so there are several courses of brick between them so as to put the designated section of wall into compression. This test is usually performed according to ASTM C 1197-92 (vol. 4.05). This standard gives a good description of the test procedure and the required calculations to determine the deformability properties of the masonry.
