Depth of water penetration under pressure

For dense and, hence, low permeability concrete, the depth of penetration method is usually a more practical proposition than permeability flow tests.

The basic procedure for such a depth of penetration test is to apply water under pressure to one surface of the specimen for a specific time and then to split the specimen perpendicular to the injected face and determine visually the depth of penetration.

The method is covered by BS EN 12390–8:2000 Testing hardened concrete – Part 8 Depth of penetration of water under pressure.
