A communications cable includes water blocking provisions which are microbial resistant. The water blocking provisions include a microbial resistantwater blocking member comprising a laminate which includes two tapes with a superabsorbent powder therebetween. Advantageously, the superabsorbent powder on contact with moisture swells to block further intrusion of moisture and to prevent its movement longitudinally within the cable. The tapes of the laminate may be non-cellulosic such as for example a spunbonded polyester material which has suitable tensile strength and which has a relatively high porosity and further which prevents the growth of fungus. An adhesive system included in the laminateis sufficient to hold together the tapes and the powder without inhibiting swelling of the powder on contact with water.
