As a high-temperature underlayment, RamShield 250HTSA helps maintain a cooler working surface while providing reliable protection under primary roofing materials. Its uniquely engineered high-traction surface enhances walkability on steep slopes—even in conditions with moisture or condensation—making installation safer and more efficient.

The adhesive layer utilizes advanced SBS-modified bitumen technology, ensuring strong, consistent adhesion across a wide range of temperatures and substrates, including plywood and metal. With a performance range from -40°F to 260°F (-40°C to 126°C), it delivers dependable durability in both extreme cold and heat. A split silicone-coated release liner simplifies handling and speeds up installation.

Manufactured at a robust 60 mil thickness, RamShield 250HTSA comes in 2-square rolls (3 ft x 66.7 ft) weighing approximately 50 lbs. Its superior tear strength and adhesion allow contractors to transport and position rolls with ease on the jobsite.

USES:

• Asphalt Shingles
• Tiles
• Shakes
• Metal roofing 

FEATURES:

• Impermeable to air, moisture vapor, and water

• Excellent self-adhesion to plywood, oriented strand board (OSB), concrete, metal, and like materials

• Flexible at low temperatures (-20 ̊F)

• Handles easily at low temperatures (-20 ̊F)

• Highly resistant to punctures and tears

USES:

• Concrete Foundation Walls

• Plaza Decks

• Tunnels

• Parking Decks

• Foundation Waterproofing

• Balconies

• Black Pearl® | Primer Adhesive

• Black Pearl® | Sheet Membrane

These components are based upon the same core formula of select, unoxidized asphalt cement base, butyl rubber, styrene isoprene styrene (SIS), neoprene rubber, styrene-butadiene-styrene rubber (SBS), carbon black, fillers, plasticizers and curing agents. The Black Pearl Primer Adhesive also has an aliphatic solvent that is within acceptable OSHA and EPA current regulations.

Black Pearl® Sheet Membrane is a 55 mil woven polyester fabric providing extra tensile strength and stability. This fabric is impregnated and coated with the Black Pearl® rubberized formula. The compatibility between the two components is 100 percent, with the Black Pearl® Primer Adhesive acting as a catalyst on the sheets and chemically fusing the system elements together (including flashings) into a thick, semi-monolithic waterproof membrane.

Black Pearl® Waterproofing System has the unique ability to be applied to green and damp concrete. It is also compatible with asphaltic products, enabling the restoration of projects that were originally asphaltic based and ties to hot rubberized asphalt. It can be applied at temperatures as low as 0ºF.

USES:

• New and restoration applications

• Plaza deck waterproofing systems

• Protected membrane roofs (IRMA®)*

• Green Roof Roofscapes®

• Vertical waterproofing applications

• Parking decks, bridges, water treatment plants

• Between slab waterproofing membrane systems
