Multi-layer Asphalt and Gravel

Built-Up Roofing (BUR) or more commonly known to the layman as “tar & gravel” roofing, consists of several plies of #15 Asphalt felt paper (usually 4-5), adhered together with hot bitumen. Another layer of hot asphalt is poured on top and clean crushed stone is embedded into the hot asphalt. The stone is simply there to prevent the sun’s UV rays from deteriorating the asphalt. BUR is heavy and is the most rugged of flat roofing systems. It is not easy to damage a BUR system. Gravel slows the contraction of the asphalt during sudden changes in temperature.

• Affordability

• Requires minimum maintenance

• Life 20-25 years

• White Gravel available

• Bestseller for flat roofs

• Traditional roof system

Inverted Roofs

Roofs, especially flat roofs, are among the most exposed parts of a building. Therefore proper structural composition is a determining factor for the life expectancy of the roof.

In flat roofs with conventional build-up, the thermal insulation is placed above the structural deck but below the waterproofing membrane.

The membrane is thermally isolated from the rest of the roof construction, thus exposed to wide temperature fluctuations with increased risk of premature failure. When applying the “inverted” roof concept, the risk of the failure is minimized. The thermal insulation boards placed on top of the roofing membrane provide protection against a number of damaging factors:

  • Temperature extremes
  • Climatic impacts and UV-radiation,
  • Mechanical impacts during the construction period, use and maintenance,
  • Blistering of the membrane: the waterproofing membrane on the warm side of the thermal insulation acts also as a vapor barrier.

Membrane is thermally isolated from the rest of the roof system, protection from condensation risk and freeze/ thaw cycles, resistant to foot traffic and exhibits a high compressive strength. Durability

Elastomeric Roof

A roof with elastomeric bitumen membrane is used on flat roofs at very high surface (commercial buildings). Hydrophobic, resistant and durable, bitumen has set the standard for waterproofing since Antiquity. A natural and noble material, bitumen is still at the cutting edge of technology today. Developed to reduce the level and maintenance of uniform quality of the seal, it is composed of a base layer and a finishing coat of colored granules in the asphalt surface to protect from sunlight.

• Requires annual maintenance

• Service life of 25 to 30 years (installation and proper ventilation will increase its lifetime up to 30 years)

• Recommended for residential due to freezing and thawing cover

Benefits of elastomer bitumen:

  • Its excellent elasticity;
  • Its flexibility;
  • Its characteristic properties at high temperatures;
  • Its characteristic properties at low temperatures;
  • Its excellent adherence to the support;
  • Its reliable and solid waterproofing for joints;
  • Its durability;

Single Sheet Membrane EPMD

EPDM Roofing System is a 100 % cured single-ply roofing membrane is made of synthetic rubber ethylene-propylene-diene terpolymer mixed with carbon black, clay, oils, curing agents and processing aids. It is calendered into large sheets and vulcanized. Due to its composition and characteristics, EPDM is the ideal, highly durable waterproofing solution for low-slope commercial and industrial roofs

  • Superior durability and longevity
    EPDM membranes offer unmatched resistance to ozone, UV radiation and extreme temperatures. Quick and easy installation
    EPDM is available in large seamless sheets up to 15.25 m wide and 61 m long (930 m²), resulting in fewer field seams for large surfaces and short installation times.
  • High flexibility and elongation
    EPDM remains highly flexible even at temperatures down to -45°C, enabling year round installation. The membrane can also elongate over 300% to accommodate building movements and temperature fluctuations.
  • Low-life cycle costs

Requires little or no maintenance

Best Quality, life span of 25-30 years

Green Roofs

Environmentally friendly, has lifespan of 25 -30 years, durable and reliable, improved air quality, Energy Saving, Increased resistance to roof and Acoustic Insulation.

A Green roof system is an extension of the existing roof that involves a high quality waterproofing and root repellant system, a drainage system, filter cloth, a lightweight growing medium and plants.Green roof development involves the creation of “contained” green space on top of a human-made structure. This green space could be below, at or above grade, but in all cases the plants are not planted in the “ground’. Green roofs can provide a wide range of public and private benefits.

White Roofs



Single sheet TPO membrane

The TPO Roof Membrane is a white single ply roof membrane which is comprised of an elastomeric thermoplastic polyolefin. TPO Roof Membrane is reinforced with high strength, wick resistant polyester fabric.

TPO Membrane is a Thermoplastic polyolefin membrane that accepts roof movement and termal shock. It can be used in a variety of single ply roof configurations, such as mechanically attached ballasted. TPO roof Membrane is lapped and seamed using hot air heat welding equipment. TPO Roof Membrane can be used in situations where other roof systems are not practical.

Waterproofing Foundation

Waterproofing interior parking

The membrane MM6125 has been successfully used worldwide by leading architects, engineers and owners on all types of horizontal and vertical structures including plazas, parking decks, planters, tunnels, bridges mud slab, foundation walls and roof areas… establishing an unbeatable 40 year track record.

The Membrane 6125 stands up to our extreme climate conditions, has been adopted by the best architects, engineers and contractors.

The membrane 6125 is a flexible, rubberized-asphalt composite, which is hot applied two to three times thicker than most competitive membrane.
