Concrete can reach its design strength and still deteriorate if water, CO₂ or chlorides get in easily. This equipment for concrete durability testing measures exactly that: carbonation with phenolphthalein, Figg permeability, resistivity, corrosion mapping, ultrasonic testing and cover meters. Tell us what your inspection involves and we will tell you which test it calls for.

Its ability to withstand its environment over the intended service life without losing its properties. In Spain, the Structural Code ensures it through exposure classes (carbonation, chlorides, frost, chemical attack) that set the minimum cover, the maximum water/cement ratio and the minimum cement content.
The reaction of CO₂ in the air with the cement paste, which advances from the surface and lowers its alkalinity. When it reaches the reinforcement, the steel loses its protection and corrodes. With phenolphthalein, sound concrete turns pink and carbonated concrete does not.
Because of carbonation or chlorides (seawater, de-icing salts), which break down the layer that protects the steel. Rust takes up more space than steel, pushes against the concrete and cracks or spalls it. Thin or porous cover speeds the process up.
How hard it is for an electric current to pass through it. Dense, dry concrete has high resistivity, lets less water and chlorides through and slows corrosion; low resistivity warns of permeable or wet concrete.
The crack width gauge, the crack microscope and the cross-hole equipment for piles are in concrete.
