Pre-Applied Sheet Grace Waterproofing Membranes

Self-Adhesive Below-Grade Pre-Applied Membranes

    Prevent water migration between the membrane and structure in every direction, ensuring protection against damaging water, moisture, and gases such as methane, radon, and other chemicals. Made of a thick HDPE film, pressure-sensitive adhesive, and protective weather-resistant coating, Grace Waterproofing PREPRUFE sheet membranes are fast and easy to install. Simply position the roll, unspool it with a kick, and secure overlaps with PREPRUFE ZipLap quick-sealing adhesive, and you're done. It provides moisture protection and is traffic-ready immediately after application and is ideal for installations in harsh climates, requiring no special equipment, heat, or power.
  • PREPRUFE 200
    PREPRUFE 200 is designed for horizontal or vertical use below slabs or behind basement walls in confined sites. Composite sheets can be applied in wet, cold, and even rainy weather installing quickly with loosely laid, mechanically fastened laps. It offers both waterproofing and vapor barrier protection (MVER 0.11 lb/1000 ft2/24 hr ASTM F1869-98), making it the solution of choice for garages, plant rooms, utility-grade basements, tunnels, and as a vapor barrier for slabs with moisture-sensitive finishes such as wood.
  • PREPRUFE 250
    PREPRUFE 250 is specially designed for environments with low hydrostatic pressure or intermittent water conditions. Use it on below-grade foundation slabs and below-grade cast-in-place walls on confined sites, including garages, utility-grade basement, and plant room additions.
  • PREPRUFE 300R & 160R
    PREPRUFE 300R and 160R can be placed directly over prepared, compacted soil, forming a continuous bond to poured concrete that isolates the structure from surrounding ground. They are BBA-Certified for all basement grades and ideal for use on below-grade slabs or behind basement walls in confined areas. Both are impermeable (less than 0.1 Perms), chemical resistant, and guard against salt and sulfate infiltration.
  • PREPRUFE 300LT & 160LT
    PREPRUFE 300LT & 160LT are designed for low-temperature applications, featuring a release liner-free design for a more efficient, reliable installation. They are unaffected by ground settlement beneath slabs and certified for all basement grades, forming a continuous bond to poured concrete, physically isolating the structure from the surrounding substrate to prevent water, vapor, and gas migration. These formulas are also chemical resistant, guarding against salt and sulfates.
    NOTE: Not for use in horizontal applications or with conventional twin-sided formwork.
  • PREPRUFE 300R Plus LT & 160R Plus LT
    PREPRUFE 300R Plus LT and 160R Plus LT feature a release liner-free design for a more efficient, reliable installation. They are unaffected by ground settlement beneath slabs, and ideal for use below slabs or behind basement walls on confined sites. It forms a continuous bond to poured concrete, physically isolating the structure from the surrounding substrate to prevent water, vapor, and gas migration.
    Unlike non-adhering tunnel membranes, Grace Waterproofing PREPRUFE 400T bonds integrally to poured concrete, preventing the migration of water into your structure. This versatile film is compatible with all tunneling applications, including cut-and-cover, drill-and-blast, and bored-and-cut.
    PREPRUFE GMS prevents hazardous gas vapors from penetrating the foundation and other building structures and is designed for use below slabs or behind basement walls on confined sites.

    NOTE: Use Grace Waterproofing BITUTHENE low-temperature membrane with ambient temperatures between 25-60°F.
  • BITUTHENE 4000
    BITUTHENE 4000 is a self-adhered rubberized asphalt waterproofing membrane and surface conditioner. It features a strong but flexible pre-formed membrane of high-performance cross-laminated HDPE film with a tacky, self-adhesive rubberized asphalt compound, and water-based primer surface conditioner specially formulated to promote adhesion.

Fluid-Applied Above & Below Grade Post-Applied Membranes

    This trowel-grade, two-component, elastomeric, cold-applied liquid membrane chemically cures to a tough, rubberlike finish. Designed for use with Grace waterproofing systems it is ideal for use at inside corners, or as flashing around drains, curbs, protrusions, and parapets. Mix and use on-site for fast detailing and complete waterproofing coverage with PREPRUFE and PROCOR waterproofing products, and asphalt, coal-tar, silicone, and polyurethane sealants.

Post-Applied Sheet Grace Waterproofing Membranes

Self-Adhesive Below-Grade Post-Applied Membranes

    PREPRUFE 800PA features a synthetic non-asphaltic adhesive and high-performance HDPE film. It adheres aggressively to building surfaces, forming a strong, durable, elastomeric membrane that accommodates movement and resists punctures, tears, cracks, and peeling, providing protection against water and vapor. It is ideal for use on basement walls in open excavation. Used in conjunction with PREPRUFE pre-applied membranes, it provides complete, seamless, fully-integrated below-grade waterproofing protection. Sustainably made with Red List Free materials, it also meets Living Building Challenge (LBC) criteria.

Fluid-Applied Below-Grade Post-Applied Membranes

  • PROCOR Below-Grade
