The internal system may be chosen instead of the external solution for a number of reasons;1) In areas that access is not possible, or removal of obstacles is not feasible (Under a deck, brand new patio slab, etc.) 2) When the cause of the leak is not through the foundation wall, but penetrating from underneath the basement slab or wall joint. In areas with a high water table where there are faults in the foundation, adding internal drainage on the inside of the footing may be the only way to catch this water.3) When considering waterproofing in unfinished basements, an internal system could be more cost effective. It is also possible to finish the basement after the waterproofing is complete to cover the system, leaving a seamless solution to your foundation problems.Your sales professional will be able to guide you on the best solution for you.
