Abstract
This invention provides reinforced, water-resistant membranes, and methods of manufacturing and installing such membranes. These membranes include a mastic layer having first and second major surfaces and a fiber-containing reinforcing layer disposed within the mastic layer for improving the mechanical strength of the membrane. The membrane can be bonded to an underlying substrate by the application of heat or pressure to form an adherent bond. The reinforced membrane of this invention can have a tensile strength of at least about 300 psi or more.
