The Hydrotech Monolithic Membrane 6125 (MM 6125) is a waterproofing/roofing membrane assembly designed for application over concrete substrates. Installation involves a specific sequence of steps, beginning with substrate preparation and culminating in the installation of a separation/protection course. The process emphasizes detailing around critical areas and includes a recommended leak detection phase prior to overburden application. This article details the installation process based on provided documentation, intended for applicators and those seeking an understanding of the system’s implementation. It is crucial to note that the provided documentation explicitly states it is an illustration and should not be considered a complete installation guideline.
Preparation of the Concrete Substrate
Prior to the application of MM 6125, thorough preparation of the concrete substrate is required. Applicators typically determine the work area for each day at the beginning of the shift. This area must be cleaned using a broom to remove loose debris, followed by compression with an air compressor to eliminate remaining dirt and dust. The documentation emphasizes the importance of a clean surface for proper membrane adhesion.
Application of Surface Conditioner
Hydrotech Surface Conditioner is specified for use exclusively on concrete substrates. The conditioner is applied via spray, adhering to recommended application rates. Complete drying of the conditioner is essential before proceeding with the installation of MM 6125. The purpose of the conditioner is not detailed in the provided documentation.
Detailing with Flex Flash
Detailing constitutes an initial phase of the installation process. This involves the application of either Hydrotech’s Flex Flash F or Flex Flash UN, encapsulated between two layers of MM 6125. Flex Flash F is utilized to reinforce areas experiencing cracks or changes in plane. Flex Flash UN serves as reinforcement at drains, expansion joints, and transitions between different construction materials. It is also employed as a flashing material for exposed parapets, walls, and curbs in roofing installations. The documentation does not specify the method of encapsulation.
MM 6125 Field Application
Following the completion of detailing work, MM 6125 is applied to the field of the deck. The membrane is typically installed as a fabric-reinforced assembly with a total thickness of 215 mils. The application process involves two coats: an initial coat of 90 mils with Flex Flash-F embedded within it, and a subsequent layer of 125 mils. The documentation does not detail the application method for the membrane layers.
Separation/Protection Course Installation
The final step in the installation process involves the installation of a separation/protection course. For roofing applications, Hydrotech Hydroflex 10 is recommended. For waterproofing applications, Hydroflex 30 is specified. This course is installed concurrently with the membrane to ensure a strong bond between the two layers. The documentation does not provide details on the method of bonding.
Leak Detection Procedures
Hydrotech strongly recommends conducting a water test of the waterproofed area or roof before applying any subsequent topping materials. This testing can be performed using either flood testing or electric conductivity testing. The purpose of this step is to verify the watertight integrity of the installation before the addition of overburden. The documentation does not provide specific instructions for performing either test.
Conclusion
The installation of Hydrotech Monolithic Membrane 6125 involves a multi-step process, beginning with thorough substrate preparation and progressing through detailing, membrane application, and the installation of a protective layer. Leak detection is a critical recommended step to ensure the integrity of the waterproofing system. The provided documentation emphasizes the importance of following a specific sequence and utilizing appropriate materials for optimal performance. However, it is crucial to remember that the documentation explicitly states it is an illustrative guide and should not be used as a substitute for comprehensive installation instructions.
