Rockal Plus
ROCKAL PLUS is a Plastomeric high performance, prefabricated, modified bitumen waterproofing membrane consisting of proprietary water- proofing bitumen compound, reinforced with Non-Woven Polyester Carrier.
Description:
Rockal Plus is a Plastomeric high performance, prefabricated, modified bitumen waterproofing membrane consisting of proprietary water- proofing bitumen compound, reinforced with Non-Woven Polyester Carrier.
Rockal Plus proprietary waterproofing com- pound is formulated with high grade bitumen modified with Atactic polypropylene (APP) to increase elasticity, flexibility, and enhanced with admixture of Thermoplastic materials to gain high heat resistance, good elongation and low temperature flexibility. To improve the UV resistance and durability for The Product, the membrane is coated with Mineral Stabilizers.
Application:
Rockal Plus waterproofing membrane are used for a wide variety of application:
- Roofing or Re-roofing for covered single layer system 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 waterproofing of foundations and engineering structures by torching, hot air generator or by using special adhesives in both cold and hot applications.
- Cleaning the substrate surface is a must, till it becomes dry, smooth, and remove any particles.
- Based on surface conditions, a coat of ROCKAL primer product will be required prior to the application of the membrane.
- According to the waterproofing system design and adhesion instruction, APP-Product can be applied to the substrate fully bonded, semi bonded or loose laid.
- Overlapping is essential as follow, side laps from 8-10 cm and end laps from 12-15 cm.
Key Features:
- High U.V. resistance (Mineral Finish).
- Excellent thermal resistance. Strong adhesion to substrate.
- Proven water impermeability.
- Chemical resistance to 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, Specially (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:
The installation methods for APP (Atactic Polypropylene) bituminous membrane vary depending on the specific requirements of the roofing system and the type of membrane being used. Some common methods of installation include:
-
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.
-
Self-adhesive method: involves removing the release paper from the self-adhesive backing on the membrane and pressing it onto the roof deck.
-
Torch-on method: involves heating the bituminous membrane with a torch and then pressing it onto the roof deck, where it will fuse and adhere to the surface.
-
Mechanically fastened method: involves using special mechanical fasteners to attach the membrane to the roof deck.
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 level of seam strength and durability. It is recommended to seek the guidance of a professional roofing contractor for the installation of an APP bituminous membrane.
