A composite drainage mat for preventing water and moisture from remaining trapped within walls and roofs of buildings which includes a weather barrier fixedly attached to a three-dimensional matrix filamentatious mat of a thermoplastic polyamide resin such as Nylon 6. The mat contains a great number of voids for permitting gas and liquid such as water to flow therethrough. The mat possesses a crush-resistance which allows the mat to withstand the compressive force of other building materials without inhibiting the ability of the mat to allow liquids and gases to flow therethrough.
