Platon Brick Plugs Without Seals

Q) What are Platon Brick Plugs Without Seals used for?

A) Platon Brick Plugs Without Seals are heavy-duty fixing plugs used to secure Platon cavity drain membranes to masonry substrates such as brick, concrete, stone and other suitable retaining structures. They are designed for use with Platon waterproof membrane systems, including Platon P8 Membrane and Platon P8 Mesh Membrane, where the membrane needs to be mechanically fixed to the wall before internal finishes are installed. Each plug is made from glass-filled polyamide for strength and durability, and measures 10mm in diameter x 75mm long. Because this version is supplied without sealing washers, it does not create a watertight fixing point by itself, so it should be used only where that is acceptable or where separate sealing is specified.

Q) What is the difference between Platon Brick Plugs Without Seals and Platon Brick Plugs With Seals?

A) The main difference is that Platon Brick Plugs Without Seals do not include the separate TPE sealing washers supplied with Platon Brick Plugs With Seals. A washered plug compresses against the membrane face to help seal the drilled fixing point, making it more suitable for general below-ground waterproofing situations where water resistance at each fixing is important. The version without seals is still the same heavy-duty 10mm x 75mm glass-filled polyamide plug, but it does not form a watertight compression seal on its own. It is better suited to low-risk above-ground applications, non-water-bearing areas, or details where the penetration is sealed separately using Platon Sealing Rope.

Q) Can Platon Brick Plugs Without Seals be used with Platon P8 Membrane?

A) Yes, Platon Brick Plugs Without Seals can be used with Platon P8 Membrane where a suitable non-sealed or separately sealed fixing detail is appropriate. Platon P8 is a cavity drain membrane used in waterproofing and damp management systems, and these plugs provide the mechanical fixing needed to hold the membrane securely against masonry substrates. In typical non-meshed membrane installations, fixing density is usually around 5 plugs per m², although the final requirement depends on the substrate, wall shape, detailing and the internal finish system being used. Where the installation is below ground and the fixing points need to be watertight, Platon Brick Plugs With Seals or separately purchased Platon Brick Plug Sealing Washers may be more appropriate.

Q) Are Platon Brick Plugs Without Seals suitable for Platon P8 Mesh Membrane?

A) Platon Brick Plugs Without Seals can be used with Platon P8 Mesh Membrane, but the fixing pattern is usually much tighter than with standard non-meshed membranes. Platon P8 Mesh is normally used where the membrane must be held closely to the wall before direct plastering, rendering or another compatible finish is applied. For that reason, a typical fixing rate is around 15 plugs per m², helping keep the membrane firm, flat and properly restrained against the substrate. Because these plugs do not include sealing washers, the installer must consider whether the fixing detail needs additional sealing. In water-bearing or below-ground areas, Platon Sealing Rope or Platon Brick Plug Sealing Washers are required.

Q) How do you install Platon Brick Plugs Without Seals?

A) Platon Brick Plugs Without Seals are installed by drilling a 10mm hole through a stud of the Platon membrane and into the masonry substrate. The plug is then inserted through the membrane and driven home with a club hammer until it secures the membrane firmly against the wall. The substrate must be sound enough to accept and hold the 75mm fixing, otherwise the plug may not grip properly. Because this version does not include a TPE washer, it should not be assumed to seal the fixing point. Where water resistance is needed, the fixing should be sealed separately using the correct Platon sealing method, such as Platon Sealing Rope or Platon Brick Plug Sealing Washers, depending on the application.

Q) When should Platon Sealing Rope be used with these plugs?

A) Platon Sealing Rope should be used when the plug fixing point needs to be sealed separately because the plug itself is supplied without a washer. Platon Sealing Rope is typically relevant where a sealed detail is required but an integral washer is not being used. The rope particularly useful in below-ground situations involving vaulted ceilings, brick arches, sloping soffits or other overhead and inclined surfaces, where a flat washer may not compress evenly against the membrane. The purpose is to seal around the penetration so the fixing does not become a weak point in the waterproofing system. The correct sealing method should always match the risk level, substrate and system design.

Q) Are Platon Brick Plugs Without Seals suitable for vaulted ceilings and brick arches?

A) Yes, Platon Brick Plugs Without Seals can be particularly useful for vaulted ceilings, brick arches and sloping soffit applications because a separate washer may not always sit evenly against curved or inclined membrane surfaces. On these types of details, the plug provides the mechanical fixing, while sealing can be formed separately with Platon Sealing Rope where the waterproofing design requires it. This approach allows the installer to fix the membrane securely while adapting the seal to the shape of the surface. Care is still needed around every fixing point, because vaulted and overhead installations can be more complex than flat wall work. The membrane must be fixed neatly, kept tight and detailed so water can drain correctly.

Q) How many Platon Brick Plugs Without Seals are needed per m²?

A) The number of Platon Brick Plugs Without Seals required depends mainly on the type of membrane being installed and the finish that will follow. As an indicative guide, Platon P8 Membrane, which is a non-meshed cavity drain membrane, is typically fixed at around 5 plugs per m². Platon P8 Mesh Membrane normally requires a much closer fixing pattern of around 15 plugs per m² because the mesh face is usually intended to support direct plastering, rendering or compatible board finishes. These figures are practical guidance rather than a substitute for project design. Substrate condition, corners, reveals, wall shape, movement, finishing method and whether a separate sealing detail is required can all affect the final fixing pattern.

Q) Can battens and dry-lining systems be fixed into Platon Brick Plugs Without Seals?

A) Yes, one of the key advantages of Platon Brick Plugs Without Seals is that they accept 5mm size 10 threaded screws through the centre of the plug, to a maximum depth of 30mm into the plug body. This allows timber battens, ply board, tracking, wall ties and suitable dry-lining systems to be fixed through the plug without drilling extra holes through the membrane. Typical batten sizes may include 25mm x 38mm or 25mm x 50mm, depending on the lining system and support requirements. To work out screw length, add the batten thickness to the required screw embedment into the plug, making sure the screw does not enter the plug by more than 30mm.

Q) What substrates can Platon Brick Plugs Without Seals be fixed into?

A) Platon Brick Plugs Without Seals are designed for fixing into suitable masonry substrates, including brickwork, concrete, stone and other stable retaining structures capable of holding a 10mm x 75mm mechanical fixing. The background must be sound, firm and able to resist the fixing load, otherwise the plug may loosen or fail to grip properly. Very friable brickwork, crumbling mortar, loose stone, hollow areas or unstable substrates should be assessed and repaired before installation. When working on older cellars, basements or mixed masonry walls, it is especially important to check the substrate condition before drilling. If the drilled hole breaks out or does not hold the plug securely, a new fixing position may be required.

Q) What are the main limitations of Platon Brick Plugs Without Seals?

A) The main limitation of Platon Brick Plugs Without Seals is that they do not form a watertight seal at the fixing point by themselves. They are therefore not the best choice for general water-bearing below-ground wall membrane fixing unless the penetration is sealed separately or Platon Brick Plug Sealing Washers are added. They should be used only where a non-sealed fixing is acceptable, or where the waterproofing design includes Platon Sealing Rope around the fixing detail. They also depend on a sound masonry substrate, so weak, friable or unstable walls can reduce fixing performance. For high-risk basement waterproofing areas, always consider whether Platon Brick Plugs With Seals would be the more suitable option.
