BG700
General Precautions
 Install BG700 in strict compliance with applicable
building codes.
 Follow Occupational Safety and Health Administration
(OSHA) safety standards; use common sense measures
and adequate precautions to prevent accidents.
Features and Benefits
 Highly durable sheet that can be used in a variety of
applications
 Rubberized asphalt and polyolefinic film on the upper
surface form two distinct water barriers
 Specially formulated SBS compound facilitates a pliable
sheet that will not crack or dry
 Self-sealing around fasteners
 Exceptional tensile, tear and elongation properties
LeakBarrier BG700 is designed as a multi-purpose waterproofing
membrane that can be used for the vertical and horizontal waterproofing
of foundation walls, tunnels, and earth shelters, as well as plaza decks,
parking decks, balconies and terraces. BG700 can also be installed in interior
applications such as bathrooms and kitchens in addition to under siding,
exterior plaster, wall flashing or anywhere it will be protected from
prolonged exposure to ultraviolet light.

Usage
Storage
 BG700 must be stored indoors, in a dry location.
 Rolls must be protected from the elements. Do not store
rolls in direct sunlight.
 Keep rolls clean and free from moisture prior to installation.
LeakBarrier BG700 is a premium self-adhering SBS modified bituminous
membrane with a high strength cross laminated polyethylene film on the upper
side and a removable silicone treated release liner on the bottom adhesive side.
The versatile membrane can be installed to a variety of substrates in residential
and selected light commercial and industrial applications.
 Extended selvage provides an asphalt-to-asphalt
adhesion at the seam for an immediate bond
 High temperature resistant up to 240°F
 Film surface is compatible with most construction sealants
 Versatile sheet adheres to a wide variety of substrates
such as concrete, plywood, OSB, metal, wood vinyl,
masonry, certain rigid insulations, insulated concrete
forms (ICF), etc.
 Can be left exposed for up to 60 days
 Store rolls at room temperature. Prolonged exposure
to elevated temperatures may reduce the adhesive
characteristic of the material.
 Do not double stack pallets.
 Install BG700 only when material interface temperatures
(air, deck, material) are 40°F and rising.
 BG700 shall not be left exposed to the sunlight for more
than 30 days.
Surface Preparation
 Surface must be clean, dry, and free of voids prior to
installing BG700.
 For best results, surface may be primed with an ASTM
D41 primer prior to installation of the membrane. When
primer is used, ensure the primer is fully dry prior to
application of BG700.
 When surface is primed, ensure the primed surface is dry
to the touch and install the membrane within the same
work day. If not, the surface shall be re-primed.
