for prolonged periods during use some footing materials such as concrete can potentially allow passage of water such as by capillary action it has been recognized that if foundation wall 102 is in direct contact with footing 104 a possible cause of water damage in the building wall that includes foundation wall 102 is water accumulation around foundation wall 102 near footing 104 due to capillary wicking through footing 104 for example when footing 104 is made of concrete small pores and fissures not separately depicted in fig1 present in the concrete can serve as capillary conduits and water can pass rise up through these pores and fissures of the concrete due to capillary action also referred to as wicking when the soil 107 surrounding footing 104 is wet water from the wet soil 107 can continuously pass through footing 104 and reach the interface region between foundation wall 102 and footing 104 in the absence of a moisture barrier such as moisture barrier 106 disposed between foundation wall 102 and footing 104 water can come into contact with and accumulate around foundation wall 102 near footing 104 the water can further rise up along foundation wall 102 for example when foundation wall 102 is made of concrete or another material that.
