Cement is a hygroscopic substance, i.e. it easily absorbs moisture from its surroundings. Moist cement easily becomes lumpy and causes binding problems, even loss of strength.

All of our bags have a layer of plastic that protects the cement, however, it is recommended that the cement bags be stored carefully out of the rain and off the damp ground. The shelf-life of cement in the concrete station’s silos depends on how full the silo is, how airtight it is and the volume of air blown in. In an airtight space, the shelf-life of cement is nearly limitless.

Even in good conditions it is not recommended to store the bags for more than three months.
