Abstract: A sealing profile for embedding in a moulded part made of curable material. Spalling observed in practice, which occur, in particular, at corners of tubbings in the area with an integrated seal, can be effectively prevented or at least reduced by using a sealing profile where the flanks of the profile base, which is embedded within the moulded part, e.g., concrete tubbing, merge with rounded portions or chamfers into the profile base face. In addition, the at least one anchoring foot is located within the profile base face and thus outside the area of the rounded portions.

Abstract: A testing device for testing seals, in particular tubbing seals, which seals have at least one anchoring foot. The testing device can be easily and cost-effectively adjusted to various seals by using plates with a recess, in which correspondingly configured plate elements are detachably inserted, so that different groove shapes scan be reproduced. The recess thus acts as a kind of “universal groove”, which can be adjusted to the respective geometry of the sealing profile to be tested by means of the plate elements, if necessary with the assistance of a curing or curable material.
