The TQC Karsten Tube Penetration Test measures the degree of water penetration into materials such as concrete, stone and plaster. The test consists of a glass tube filled with water, bonded to the test material with plastiline. Water pressure is then exerted on the surface. A graduated scale indicates the amount or water penetrated into the surface over time.
The Test contains 3 tubes for horizontal surfaces, 3 tubes for vertical surfaces (or at choice any other combination of total 6 tubes), a water bottle, marker and putty to place the tubes leak-tight on the surface
