Rock Sheild

Description

Rock Sheild is an Elastomeric high performance, prefabricated, modified bitumen mem- brane consisting of proprietary waterproofing bitumen compound, reinforced with non-woven polyester Carrier.

Rock Sheild 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 for The Product, the membrane is coated with Mineral Stabilizers.

Application

Rock Sheild 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 be comes 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, SBS-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.
•  Please refer to the ROCKAL applicator guide for complete instruction on the application of the product 

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

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 level of seam strength and durability. It is recommended to seek the guidance of a professional roofing contractor for the installation of an SBS bituminous membrane.
