Waterproofing and Roofing Systems
Black Pearl® Waterproofing System is composed of two primary products:
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.
RamTough KLB-100 SEBS rubber material's web-like molecular structure creates a microscopic, elastic network of strong, rubberized strands with tough, interlocking styrene end blocks. During the polymerization process, the polymer network absorbs the asphalt light ends, producing a rubberized waterproofing material with properties that are far superior to regular oxidized roofing grade asphalt.
RamTough KLB-100 when combined with appropriate modified bitumen membranes, polyester or fiberglass ply sheets or cap sheets, delivers a compatible composite roofing membrane with extraordinary toughness, puncture, and impact resistance. RamTough KLB-100 is also recommended for buildings intolerant of water intrusion for high-performance requirements. When the building design requirements are for a long-life cycle, RamTough KLB-100 is a cost-effective solution.
Ram 306-FR is a fire-resistant, granule surfaced, premium SBS (Styrene-Butadiene-Styrene) mop or cold applied membrane manufactured with a fiberglass mat that is saturated and coated with high quality, asphaltic bitumen and SBS elastomers for a durable, flexible and easily maintainable roofing membrane. Ram 306-FR comes with black or white granule surfacing, both of which offer resistance to ultraviolet rays and damage caused by foot traffic. The light colored granules provide improved reflectivity.
Roofscape® Extensive Media is a planting medium for extensive vegetative Greenroof-Roofscapes® systems with a separate drain layer, designed to retain stormwater and to promote long lasting vigorous plant growth, and which meets the requirements described in ASTM E2777-14 Standard Guide for Vegetative (Green) Roof Systems (see Technical Data Sheet for more info).
Roofscape® Extensive Media is a precisely balanced blend of carefully selected lightweight mineral aggregates and premium organic components, like USCC STA approved compost.
At the start of the production cycle, Sedum album, Sedum acre, Sedum hispanicum and Sedum sexangulare make up approximately 15% of the assortmentused to produce a Yellow/Blue Greenroof-Roofscapes® Sunray Sedum-Mix Blanket. The remaining 85% consists of a mixture of Sedum rupestre ‘Angelina' and Sedum reflexum ‘Blue Spruce'.
The Sedum-mix blanket is the most widely applied product for directly green extensive green roof system, also called Sedum roofs. On delivery our vegetation blankets always boasts at least 85% coverage. All of Barrett's Greenroof-Roofscapes® vegetation blankets are produced in accordance with FLL guidelines.
The Maroon Sedum-mix blanket is a ready-to-lay ground cover vegetation blanket for roundabouts, central reservations, roof terraces, and more. Grown in a mineral-based substrate layer on a biodegradable coconut fibre mat, the Maroon Sedum-Mix Blanket contains 6 to 7 different succulent varieties specially selected to create a red assorted vegetation blanket.
The Sedum-mix blanket is the most widely applied product for directly green extensive green roof system, also called Sedum roofs. On delivery our vegetation blankets always boasts at least 85% coverage. All of Barrett's Greenroof-Roofscapes® vegetation blankets are produced in accordance with FLL guidelines.
Roofscape® Pre-Grown Tray System provides a turnkey solution that meets or exceeds all guidelines for Green Roofs. The trays are easy to install and feature interlocking edges which prevent shifting or migration of growing media onto the roof membrane. At 24" x 24" x 4.625" deep, the pre-grown tray is appropriate for extensive and semi-intensive vegetative roof profiles. The modules are pre-grown with plants (most commonly sedum) selected by the project designer and shipped to the job site with approximately 90% or more vegetation coverage.
Comprised of a heavy-duty recycled polypropylene, the Roofscape® Pre-Grown Tray is designed with a channelized bottom to maximize stormwater retention. It can reduce both the amount and rate of stormwater run-off and is capable of retaining up to 70% of annual precipitation. Detailed stormwater retention calculations and hydrographs are available upon request.
