Substrate Suitability:

Platinum CV8 Cavity Drain Membrane is suitable for a wide range of substrates, particularly those found in below-ground construction, such as concrete, brick, and stone. It is designed to be used in environments where water ingress is a significant concern, including basements, tunnels, and vaults. The membrane can be applied to both walls and floors, provided the substrate is sound, clean, and free from contaminants that could impair adhesion or waterproofing performance.

For new construction projects, it is essential that the concrete slab is laid in strict accordance with BS 8204-1:2003+A1:2009 standards. This ensures a flat and even surface, with deviations of no more than 5mm over a 3000mm straight edge. This precision is crucial to avoid any air gaps that could compromise the effectiveness of the membrane. For existing structures, any unsound plaster, render, or screed should be removed, and the surface should be levelled accordingly. Where necessary, Platinum Fillet Seal or a 3:1 sand:cement mix incorporating Wykamol Renderproof Waterproofing Additive should be used to achieve the required surface standards.

 

Surface Preparation:

Proper surface preparation is vital to ensure the optimal performance of Platinum CV8 Membrane. Begin by thoroughly cleaning the substrate to remove any loose debris, dust, or surface contamination. In cases where walls are affected by mould or masonry fungi, it is crucial to address these issues before applying the membrane. Use a stiff brush to remove surface contamination, followed by an application of Lignum Pro M50 Biocide in accordance with the relevant Technical Data Sheet. If dry rot (Serpula Lacrymans) is detected, a detailed assessment should be conducted, and further advice should be sought from our Technical Department.

For installations above ground level, it is advisable to alleviate all sources of moisture at the source, where possible. This can be achieved by installing a Damp Proof Course (DPC), such as DampSolve Damp Proof Cream, before applying the CV8 membrane. This preventative measure reduces the potential for damage to masonry and timber, safeguarding the long-term integrity of the structure.

 

Application Method:

When applying Platinum CV8 membrane, it is essential to follow a precise and methodical approach to ensure a successful installation. Begin by positioning the membrane with the studs facing the wall. Fixing is accomplished using Platinum Waterseal Brick Plugs, which should be inserted into pre-drilled holes at regular intervals of no more than 600mm. This spacing may vary depending on the specific site conditions and the size of the batten or board being installed. To enhance adhesion and prevent lime efflorescence and dusting, it is recommended to apply Wykamol Anti-Lime Sealer to concrete walls and slabs before installing the CV8 membrane.

When drilling holes for the plugs, take care to prevent excessive masonry dust from falling into the cavity, as this could obstruct drainage channels. Insert the chosen plug, ensuring it is fitted with a seal for all underground waterproofing applications, and secure it using a rubber mallet or club hammer. Seal the membrane at the flanges—bands of membrane along the edges where no studs are present—using Platinum Waterseal Tape. Ensure that these flanges run vertically on walls and overlap the preceding width of membrane. For stud-to-stud joints, use Platinum Waterseal Rope to achieve a watertight seal.

When dealing with vaulted ceilings, the membrane can be successfully applied by carefully sealing all mitred joints with Platinum Waterseal Tape, Platinum Waterseal Rope, Platinum Corner Tape, or Platinum Mesh Tape as required. This meticulous approach ensures that even complex structures are fully protected against water ingress.

 

Conditions & Limitations:

It is important to recognise the conditions and limitations associated with the use of Platinum CV8 membrane. The membrane is not suitable for application to flat soffits below ground level, as these require a minimum slope of 10% to function effectively. When running the membrane around internal and external corners, take extra care to ensure that it is fixed tightly to the angle, creating well-defined edges that facilitate the application of subsequent finishes.

The membrane should not be exposed to direct sunlight for prolonged periods, as UV exposure can degrade the material over time. Additionally, while the membrane can tolerate a wide range of temperatures, it should be stored and installed under conditions that prevent exposure to extreme temperatures and open flames.

 

Finishing:

Finishing the installation of Platinum CV8 membrane requires careful consideration of the intended final surface. For stud frame construction, Platinum Waterseal Brick Plugs should be applied in a vertical line, aligning with the stud locations and battens. Fix the stud frame to the plugs using No. 10 screws (5mm), taking care not to perforate the membrane. If straight alignment of the plugs is not possible, 'Gyproc' brackets can be used to secure the battens in place.

When finishing floors, the CV8 membrane can be overlaid with closed-cell insulation before laying tongue-and-groove (T&G) flooring. Ensure a 10mm expansion joint is maintained around the perimeter. Alternatively, a conventional sand and cement screed, approximately 65mm thick, can be laid. The specific conditions of the site may dictate variations to this method, and in cases of uncertainty, it is recommended to consult our Technical Department for guidance.

During the application and finishing process, ensure that atmospheric moisture levels do not exceed 70% relative humidity (RH). Impermeable floor finishes should only be applied when the screed moisture content is below 75% RH to avoid compromising the performance of the membrane.

 

Aftercare:

Platinum CV8 membrane, once installed, provides a long-lasting solution for controlling damp and moisture ingress in below-ground structures. To maintain a dry and habitable environment, particularly in areas lacking natural ventilation, it is crucial to implement adequate condensation control measures.

This is especially important in wet areas such as kitchens and bathrooms. The installation of an effective mechanical ventilation system is recommended to prevent the build-up of condensation, which could otherwise lead to secondary moisture problems. For detailed advice on appropriate ventilation systems, contact our Technical Department.

 

Storage & Shelf Life:

Platinum CV8 membrane should be stored in an upright position, under cover, and away from sources of high temperatures and open flames. When stored correctly and installed in accordance with the datasheet recommendations, the membrane's shelf life is equivalent to the lifetime of the structure. Proper storage conditions ensure that the membrane retains its performance characteristics and remains effective for the duration of its intended use.

Substrate Suitability:

Platinum CV8 Cavity Drain Membrane is suitable for a wide range of substrates, particularly those found in below-ground construction, such as concrete, brick, and stone. It is designed to be used in environments where water ingress is a significant concern, including basements, tunnels, and vaults. The membrane can be applied to both walls and floors, provided the substrate is sound, clean, and free from contaminants that could impair adhesion or waterproofing performance.

For new construction projects, it is essential that the concrete slab is laid in strict accordance with BS 8204-1:2003+A1:2009 standards. This ensures a flat and even surface, with deviations of no more than 5mm over a 3000mm straight edge. This precision is crucial to avoid any air gaps that could compromise the effectiveness of the membrane. For existing structures, any unsound plaster, render, or screed should be removed, and the surface should be levelled accordingly. Where necessary, Platinum Fillet Seal or a 3:1 sand:cement mix incorporating Wykamol Renderproof Waterproofing Additive should be used to achieve the required surface standards.

 

Surface Preparation:

Proper surface preparation is vital to ensure the optimal performance of Platinum CV8 Membrane. Begin by thoroughly cleaning the substrate to remove any loose debris, dust, or surface contamination. In cases where walls are affected by mould or masonry fungi, it is crucial to address these issues before applying the membrane. Use a stiff brush to remove surface contamination, followed by an application of Lignum Pro M50 Biocide in accordance with the relevant Technical Data Sheet. If dry rot (Serpula Lacrymans) is detected, a detailed assessment should be conducted, and further advice should be sought from our Technical Department.

For installations above ground level, it is advisable to alleviate all sources of moisture at the source, where possible. This can be achieved by installing a Damp Proof Course (DPC), such as DampSolve Damp Proof Cream, before applying the CV8 membrane. This preventative measure reduces the potential for damage to masonry and timber, safeguarding the long-term integrity of the structure.

 

Application Method:

When applying Platinum CV8 membrane, it is essential to follow a precise and methodical approach to ensure a successful installation. Begin by positioning the membrane with the studs facing the wall. Fixing is accomplished using Platinum Waterseal Brick Plugs, which should be inserted into pre-drilled holes at regular intervals of no more than 600mm. This spacing may vary depending on the specific site conditions and the size of the batten or board being installed. To enhance adhesion and prevent lime efflorescence and dusting, it is recommended to apply Wykamol Anti-Lime Sealer to concrete walls and slabs before installing the CV8 membrane.

When drilling holes for the plugs, take care to prevent excessive masonry dust from falling into the cavity, as this could obstruct drainage channels. Insert the chosen plug, ensuring it is fitted with a seal for all underground waterproofing applications, and secure it using a rubber mallet or club hammer. Seal the membrane at the flanges—bands of membrane along the edges where no studs are present—using Platinum Waterseal Tape. Ensure that these flanges run vertically on walls and overlap the preceding width of membrane. For stud-to-stud joints, use Platinum Waterseal Rope to achieve a watertight seal.

When dealing with vaulted ceilings, the membrane can be successfully applied by carefully sealing all mitred joints with Platinum Waterseal Tape, Platinum Waterseal Rope, Platinum Corner Tape, or Platinum Mesh Tape as required. This meticulous approach ensures that even complex structures are fully protected against water ingress.

 

Conditions & Limitations:

It is important to recognise the conditions and limitations associated with the use of Platinum CV8 membrane. The membrane is not suitable for application to flat soffits below ground level, as these require a minimum slope of 10% to function effectively. When running the membrane around internal and external corners, take extra care to ensure that it is fixed tightly to the angle, creating well-defined edges that facilitate the application of subsequent finishes.

The membrane should not be exposed to direct sunlight for prolonged periods, as UV exposure can degrade the material over time. Additionally, while the membrane can tolerate a wide range of temperatures, it should be stored and installed under conditions that prevent exposure to extreme temperatures and open flames.

 

Finishing:

Finishing the installation of Platinum CV8 membrane requires careful consideration of the intended final surface. For stud frame construction, Platinum Waterseal Brick Plugs should be applied in a vertical line, aligning with the stud locations and battens. Fix the stud frame to the plugs using No. 10 screws (5mm), taking care not to perforate the membrane. If straight alignment of the plugs is not possible, 'Gyproc' brackets can be used to secure the battens in place.

When finishing floors, the CV8 membrane can be overlaid with closed-cell insulation before laying tongue-and-groove (T&G) flooring. Ensure a 10mm expansion joint is maintained around the perimeter. Alternatively, a conventional sand and cement screed, approximately 65mm thick, can be laid. The specific conditions of the site may dictate variations to this method, and in cases of uncertainty, it is recommended to consult our Technical Department for guidance.

During the application and finishing process, ensure that atmospheric moisture levels do not exceed 70% relative humidity (RH). Impermeable floor finishes should only be applied when the screed moisture content is below 75% RH to avoid compromising the performance of the membrane.

 

Aftercare:

Platinum CV8 membrane, once installed, provides a long-lasting solution for controlling damp and moisture ingress in below-ground structures. To maintain a dry and habitable environment, particularly in areas lacking natural ventilation, it is crucial to implement adequate condensation control measures.

This is especially important in wet areas such as kitchens and bathrooms. The installation of an effective mechanical ventilation system is recommended to prevent the build-up of condensation, which could otherwise lead to secondary moisture problems. For detailed advice on appropriate ventilation systems, contact our Technical Department.

 

Storage & Shelf Life:

Platinum CV8 membrane should be stored in an upright position, under cover, and away from sources of high temperatures and open flames. When stored correctly and installed in accordance with the datasheet recommendations, the membrane's shelf life is equivalent to the lifetime of the structure. Proper storage conditions ensure that the membrane retains its performance characteristics and remains effective for the duration of its intended use.
