BentoShield Max PE – Polyethylene-Coated Bentonite
Bentoshield Max th
BentoShield Max PE, used in foundation and curtain wall waterproofing applications, can be applied directly to the compacted soil surface. Thanks to its structure that forms a mechanical bond with the concrete, it restricts water migration between the waterproofing material and the concrete, thereby helping to maintain system integrity and long-term watertightness performance.
Thanks to its high puncture resistance, it withstands mechanical stresses that may occur during application and—depending on project conditions—can reduce the need for a protective screed, protective geotextile, or protection board. It offers a reliable waterproofing solution for the foundation and retaining wall sections of structures such as residences, industrial facilities, hospitals, and schools, particularly in aggressive groundwater conditions.
BentoShield Max PE – Functions of Polyethylene-Coated Bentonite
BentoShield Max PE is a composite waterproofing system consisting of a combination of polymer-modified sodium bentonite granules, high-strength geotextiles, and a polyethylene coating. Upon contact with water, it swells to form a self-healing, active hydraulic barrier. Its polyethylene-coated structure provides additional protection against the passage of liquids and water vapor, supporting long-term sealing performance in foundation and curtain wall applications.
Active Waterproofing
Upon contact with water, polymer-modified bentonite swells to form an active hydraulic barrier, limiting the passage of water into structural elements.
Structural Preservation
In foundation and shear wall applications, it contributes to preserving the system's integrity and long-term performance by limiting water penetration into the reinforced concrete structure.
Liquid and Vapor Barrier
Its polyethylene-coated structure supports insulation performance by creating an additional barrier against the passage of liquids and water vapor.
Waterproofing for Aggressive and Contaminated Environments
BentoShield Max PE is a self-healing waterproofing material developed for the foundation and curtain wall waterproofing of structures such as residential buildings, industrial facilities, hospitals, and schools. It delivers reliable performance in aggressive environments characterized by high concentrations of acids and salts.
Bentoshield Max PE Features
- Bentoshield Max PE provides waterproofing for foundations and walls in seawater or acidic-alkaline environments.
- Due to its high resistance to punctures, a protective cap is not required.
- Bentoshield Max PE can be applied directly onto compacted ground without requiring a subbase.
- The need for brick walls is eliminated in concrete wall construction.
- Bentoshield Max PE prevents water from seeping into the structure by forming a mechanical bond with the concrete.
- It is not applied to protective geotextiles and protection boards in foundation and curtain wall construction.
- Bentoshield Max PE repairs the structure by sealing cracks in foundation and curtain wall concrete that may occur due to settlement.
- It has the ability to self-repair.
- Bentoshield Max PE saves both money and time by reducing the volume of excavation, as it eliminates the need for blinding concrete and a protective screed.
Frequently Asked Questions
What is BentoShield Max PE?
BentoShield Max PE is a composite waterproofing material consisting of polymer-modified sodium bentonite, high-strength geotextiles, and a polyethylene film layer.
In which areas is BentoShield Max PE used?
It can be used for the waterproofing of building foundations and reinforced concrete shear walls. It has been developed specifically for aggressive soil and groundwater conditions characterized by high concentrations of acids or salts.
How does BentoShield Max PE provide waterproofing?
When the bentonite layer comes into contact with water, it undergoes hydration and swells, forming an active hydraulic barrier with low permeability. The polyethylene film, in turn, provides an additional barrier against the passage of water and moisture.
What is the purpose of polyethylene coating?
The polyethylene film supports the waterproofing and mechanical strength of the bentonite insulation system. Thus, it contributes to the creation of a stronger protective layer in foundation and retaining wall applications.
Can BentoShield Max PE self-heal?
The swelling property of bentonite upon contact with water helps seal small voids and minor damage in the waterproofing layer. This characteristic is not a structural crack repair, but rather an active mechanism that supports the integrity of the waterproofing system.
What should be considered during the application of BentoShield Max PE?
The application surface must be prepared, and the overlapping and fixing details must be executed in accordance with the technical specifications. Product selection must be based on the ground structure, the chemical properties of the groundwater, and the waterproofing requirements of the project.
