The image you see above may seem strange, but to many California construction companies, this is very common. The black membrane you see used at various points on the exterior of this home is FutureFlash®, a mechanically-attached waterproofing membrane manufactured by MFM Building Products.
FutureFlash® was specifically developed for stucco applications, where high moisture content is present. It is also ideal to waterproof recessed windows where water can pool and lead to failure of the flashing system. This unique system is protected by US Patent No. 6,103,356, is listed under ICC-ES ESR-2783, and meets the requirements of Uniform Building Code Section #1 707(b).
FutureFlash® is made from two high-performance films with a core of specially formulated rubberized asphalt. It's tough, self-sealing and flexible with great tear strength and UV stability. The product is available in both 25 and 40 thickness in multiple slit width sizes up to 36".

Moisture Diversion Method® of Installation
MDM is a patented waterproofing system that is installed under all window and door assemblies. This Method is very effective, while lowering material and labor costs when compared to systems fabricated out of sheet metal, vinyl or plastic products.
The Moisture Diversion Method® uses FutureFlash® waterproofing membranes, Butterfly Tape™ and FutureFlash® Sealant to create a weep system that channels water to the outside for complete waterproofing protection.
