It is a double-sided self-adhesive butyl tape that sits inside membrane overlaps, flange joints and stud-into-stud laps, bonding one membrane sheet directly to the next. This is important because waterproof membrane systems must work as a connected barrier, rather than separate sheets with weak joint lines between them. The tape seals the overlap from within the lap, helping reduce water movement through the joint. It is commonly used in basement waterproofing, below-ground membrane installations, wall and floor membrane jointing, corners, reveals and detailed service areas.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How does Wykamol Membrane Sealing Tape work?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape works by bonding two membrane surfaces together from inside the overlap. The tape is positioned between adjoining sheets, with the release backing removed progressively as it is laid along the lap, flange or stud-into-stud joint. Once the second membrane sheet is pressed onto the exposed adhesive face, the double-sided butyl compound grips both surfaces and forms a watertight seal along the joint line. This internal bonding method is different from using a wider surface tape, because the seal becomes part of the membrane joint itself. The flexible butyl rubber helps the tape conform to flanges, studs and slightly irregular membrane profiles.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Where should Wykamol Membrane Sealing Tape be used?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape should be used wherever \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/wykamol-membrane\" target=\"_blank\"\u003e\u003cstrong\u003eWykamol cavity drain waterproof membrane\u003c\/strong\u003e\u003c\/a\u003e sheets need to be joined together with a sealed internal lap. Typical areas include membrane overlaps, flange joints, stud-into-stud laps, abutting joints, corners, reveals and wall-to-floor transition details. It can also be used where membranes have been cut, shaped or overlapped around pipes, cables, conduits, protrusions or service entries, provided a proper joint or overlap can be formed. Its purpose is to maintain waterproofing continuity between adjoining membrane sheets. It should be used as part of the complete \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/wykamol-membrane\" target=\"_blank\"\u003e\u003cstrong\u003eWykamol Waterproof Membrane System\u003c\/strong\u003e\u003c\/a\u003e, especially in basements, cellars and below-ground structures where joint sealing is critical.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What size is Wykamol Membrane Sealing Tape?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape is supplied in 30mm wide x 22m long rolls, with a thickness of 2mm. The narrow 30mm width is deliberate, as this tape is designed for internal membrane jointing rather than covering the face of a joint like a wider corner or detailing tape. It sits neatly within the membrane overlap, bonding one sheet directly to another without unnecessarily spanning across the exposed surface. The 2mm thickness gives the butyl enough body to conform to the membrane profile and maintain close contact between the two sheets. This makes it suitable for secure sheet-to-sheet jointing in \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/wykamol-membrane\" target=\"_blank\"\u003e\u003cstrong\u003eWykamol cavity drain waterproof membrane\u003c\/strong\u003e\u003c\/a\u003e installations.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How do you apply Wykamol Membrane Sealing Tape?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape should be applied between clean, dry membrane surfaces. The tape is positioned along the overlap, flange or stud-into-stud lap, with the backing paper removed gradually as the tape is laid into place. Once the tape is correctly aligned, the adjoining membrane sheet should be pressed firmly against it to close the joint and complete the seal. Full contact is important because the butyl must bond to both membrane surfaces along the full joint length. In cold or damp site conditions, a heat gun is often used carefully to dry the membrane surface and assist adhesion before the joint is closed. Loose edges, trapped debris and poor alignment should be avoided.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Wykamol Membrane Sealing Tape be used at wall-to-floor junctions?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape can be used at wall-to-floor transition details where the wall and floor membranes are overlapped or connected and a sealed internal joint is required. Its main function is sheet-to-sheet bonding, so it should sit within the lap where the two membrane surfaces meet. It is not a wide face-sealing tape, so broader junction detailing may also require Wykamol Corner Strip Tape depending on the system design and site detail. Used correctly, Wykamol Membrane Sealing Tape helps form a watertight connection between wall and floor membrane sections, supporting the continuity of the complete basement waterproofing or cavity drain membrane installation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Wykamol Membrane Sealing Tape be used around pipes and service penetrations?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Wykamol Membrane Sealing Tape can be used around pipes, cables, conduits and protrusions where the membrane has been cut or shaped and a sealed overlap or joint can be formed. Service penetrations are important detailing points because they interrupt the waterproof membrane layer and can become routes for water movement if left poorly sealed. The tape is used within the membrane joint around the penetration, bonding overlapping surfaces together and helping maintain continuity of the waterproof layer. For awkward or irregular service details, careful cutting, positioning and firm pressure are essential. Wider surface detailing tapes may also be needed where the penetration requires additional external sealing.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can you plaster or render over Wykamol Membrane Sealing Tape?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape is not designed to provide a direct plaster or render key. Its purpose is to create a watertight butyl bond between membrane sheets, not to provide a textured surface for finishing materials to grip. Where Wykamol Membrane Sealing Tape is used on meshed membranes that will receive direct plaster or render, \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/wykamol-mesh-tape\" target=\"_blank\"\u003e\u003cstrong\u003eWykamol Mesh Tape\u003c\/strong\u003e\u003c\/a\u003e should be applied over the sealed joint to reinstate the surface key. This allows the sealing tape underneath to perform the waterproof jointing function, while the mesh tape provides the finish-friendly surface needed for plaster or render adhesion. Without this additional key, the finish may not bond reliably over the joint area.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the main advantages of Wykamol Membrane Sealing Tape?\u003c\/h3\u003e\n\u003cp\u003eA) The main advantage of Wykamol Membrane Sealing Tape is that it creates a watertight sheet-to-sheet bond within the membrane overlap, helping the installation perform as one continuous waterproofing layer. Its double-sided self-adhesive format removes the need for a separate adhesive, while the butyl rubber construction provides strong adhesion, flexibility and resistance to water, air and chemical exposure. The 30mm width is well suited to controlled internal jointing, and the 2mm thickness helps the tape conform to membrane flanges, laps and studded profiles. It is useful not only for straight overlaps, but also for abutting joints, corners, reveals, wall-to-floor transitions and carefully formed service details.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the limitations of Wykamol Membrane Sealing Tape?\u003c\/h3\u003e\n\u003cp\u003eA) Wykamol Membrane Sealing Tape should not be used as a substitute for correct membrane installation, proper overlap formation or wider detailing tapes where they are required. It is an internal double-sided jointing tape, designed to sit between membrane sheets, not a surface-applied tape for covering large gaps, broad corners or exposed membrane edges. It must be applied to clean, dry membrane surfaces, as dust, moisture, grease, poor alignment or insufficient pressure can reduce adhesion and compromise the seal. It also does not provide a plasterable or renderable surface by itself.
