Most construction professionals recommend having a drained cavity system to save your basement from undesirable water logging. A drained cavity system is an internal mechanism well equipped with high density polythene membranes. The cavity system is mechanically applied to the wall of the ceiling thus giving way to a sort of air gap which you can easily detect on the vertical plain. The best part of a drained cavity system is that it can be installed in all weather conditions which becomes impossible in case of an external spray or a bonded membrane product.

A spray or a membrane cannot be applied at any time and in all weather conditions because they need to get dry after being applied. Again, a drained cavity system requires minimum surface preparation. Thus you don’t have to go for any bush hammering or sand blasting which can be quite damaging for any structure. Thus, consult a professional first and he will instruct you how to go about with a process of installing a drained cavity without any hassle and challenges.
