From raincoats, to umbrellas, to galoshes there are many ways to keep ourselves dry in a rain event. But how do we keep our built structures dry in inclement weather?

From roof tops to foundations and all the places in-between, what are the available waterproofing systems and strategies available to find what is right for your situation? Come join our presentation on waterproofing methods to find the right solution for your needs and to make sure you keep your head above water.

We will look at the sources of moisture intrusion and the difference between water resistance and waterproofing.  Various waterproofing methods and strategies.will be explored and we will identify the various types of waterproofing options, and the design measures necessary to prevent water intrusion.  Finally, we will investigate the ramifications of a failed waterproofing strategy.
