Working from the Inside of Foundation Walls

We often see attempts to correct basement moisture by elaborate and very expensive interior drainage systems. While such systems may be called for in some extreme cases, most are of questionable value. In any case, a good downspout drain system is a vital component to any basement moisture control system and likely to be the only system you need. And so its best to start from the outside!

Another common, and usually unsuccessful way to deal with basement water infiltration is the plugging and sealing of the basement walls. Plugging and sealing new concrete foundation from the outside is a good and prudent practice. Interior caulking and coatings tend to be of little value, and as with interior drain systems, no substitute for an exterior drain system.
