Rock Proof

ROCK PROOF is an Elastomeric high-performance, prefabricated, modified bitumen membrane consisting of a proprietary waterproofing bitumen compound, reinforced with a non-woven polyester Carrier.

Description

Rock Proof is an Elastomeric high-performance, prefabricated, modified bitumen membrane consisting of a proprietary waterproofing bitumen compound, reinforced with a non-woven polyester Carrier.

Rock Proof proprietary waterproofing compound is formulated with high-grade bitumen modified with Styrene Butadiene Styrene (SBS) polymer which provides additional elasticity flexibility and dynamic resistance, The membrane withstands temperature fluctuations and high mechanical loads providing a long-term, reliable, and effective waterproofing.

To improve the UV resistance and durability of The Product, the membrane is coated with Mineral Stabilizers.

Application

Rock Proof waterproofing membranes are used for a wide variety of applications:

• Roofing or Re-roofing for covered single-layer systems or as a base layer for multi-layer systems.
• Wet area, Swimming Pool, and Toilets.
•  Underground waterproofing
•  Flat and Sloped roofing

 The Product could be applied for the waterproofing of foundations and engineering structures by torching a hot air generator or by using special adhesives in both cold and hot applications

• Based on surface conditions, a coat of ROCKAL primer product will be required before the application of the membrane.
•  According to the waterproofing system design and adhesion instructions, SBS-Product can be applied to fully bonded, semi-bonded, or loose-laid substrates. 

• Please refer to the ROCKAL application guide for complete instructions on the application of the product

Key Features

• High U.V. resistance (Mineral Finish).
• Excellent thermal resistance.
• Strong adhesion to the substrate
• Proven water impermeability.
• Chemical resistance to a wide range of light acidic, alkaline solutions and bacteria.

Reinforcement

There are several types of reinforcement materials used in bituminous membranes, including:

• Non- woven Glass fiber Reinforcement: provides tensile strength and dimensional stability

• Non-woven polyester fabric: provides tensile strength and stability

• Non-woven Polyester reinforcement reinforced with fiberglass filaments composite: Very high tensile strength, excellent elongation properties, and good dimensional stability.
• Compound Base: High tensile strength and good dimensional stability 

The choice of reinforcement material depends on the specific requirements of the roofing system and the desired properties such as reflectivity, dimensional stability, and resistance to environmental factors.

Surface Finish

The surface finish of a bituminous membrane refers to the final appearance of the membrane once it has been installed on the roof. The surface finish can have an impact on the overall aesthetic of the roof, as well as its performance. Some common types of surface finishes for bituminous membranes include:

• Sand finish: a rough, textured surface that helps to increase the coefficient of friction and improve slip resistance, especially (White/Yellow)

• Granulated finish: a surface that is covered with small, granulated particles, typically made of a durable material such as aluminum oxide. This finish provides a high level of slip resistance and UV stability. Available in colors (Red, Grey, Green)

• Smooth finish: a smooth surface that provides a sleek, modern appearance, but may have lower slip resistance compared to other finishes.

The choice of surface finish depends on the specific requirements of the roofing system, such as the desired level of slip resistance and the type of roof deck.

Methods of Installation

SBS (Styrene Butadiene Styrene) bituminous membranes are installed using a variety of methods, including:

• Heat-welded seam method: involves heating the overlapped edges of the membrane with a propane torch to create a seamless, watertight bond between the two pieces of membrane.

• Cold adhesive method: involves using a cold-applied adhesive to bond the membrane to the roof deck.

• Mechanically fastened method: involves using special mechanical fasteners to attach the membrane to the roof deck.

• Ballasted method: involves placing heavy stones or pavers on top of the membrane to keep it in place, without the need for fasteners or adhesives.

The choice of installation method will depend on factors such as the type of roof deck, the local building codes and regulations, and the desired seam strength and durability level. It is recommended to seek the guidance of a professional roofing contractor to install an SBS bituminous membrane.
