Waterproofing basement walls is a very important task you must complete, even if there is no actual problem. One of the most effective waterproofing materials is the crystalline capillary known also as crystalline waterproofing material (CWM). It is a material used in concrete sidings and walls because it can penetrate the concrete and change its basis, making it impenetrable to water. CWM is ideal for waterproofing basement walls to prevent leaks and seepage, as well as to manage existing water issues. Before applying it, you should be aware of certain tips in order to avoid mistakes associated with its use.


Concrete walls need to be thoroughly prepared for the application of the CWM. You should not omit preparation, because scraping off the concrete and older paint is an essential part of the waterproofing basement process. Repairs are also necessary. If there are holes and cracks, you need to clean and fill them, removing debris as you go.

Watering the Walls

One of the most common mistakes is to not water the walls; most people think that since they apply a waterproofing material, they should keep the walls dry upon application. That is wrong because this particular type of material forms a thick paste when mixed with water.

The CWM heats and then forms a pliable paste which becomes an effective waterproofing coating. You should water the coating for 48 hours, so it penetrates the walls more effectively. CWM is very effective if you follow the instructions of the manufacturer as closely as possible.
