In older properties, particularly those built with cob, soft brick, friable stone or deteriorated blockwork, standard plaster plugs can fail to grip properly because the base material is weak, loose, uneven or simply too low in density to retain a conventional fixing under load. Platinum Cob Plugs address this problem directly through an expanding-stem design that anchors far more effectively into the substrate once the supplied central pin is driven into the plug body, making them particularly valuable for remedial damp proofing, heritage refurbishment and membrane installations where the wall condition is unsuitable for standard fixing methods.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eAvailable In 60mm And 90mm Lengths With Reliable Expansion Mechanism\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe plugs are available in two lengths, 60mm and 90mm, both with a 10mm width and an expanding action specifically designed to improve fixing strength within poor-quality backgrounds.

Once positioned through the membrane and into the drilled hole, the central nail or pin is driven into the plug body, causing the stem to expand and grip firmly into the surrounding material. This expansion mechanism is precisely what allows Platinum Cob Plugs to perform reliably where standard membrane fixings would loosen or pull out under the weight of the applied finish.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eCompatible With Platinum And Multiple Other Damp Proof Membrane Systems\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003ePlatinum Cob Plugs are used in above-ground damp proofing installations with both meshed and non-meshed \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/damp-proof-membrane-platinum\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum Damp Proof Membranes\u003c\/strong\u003e\u003c\/a\u003e, including \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/damp-proofing-membrane-dm2\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum DM2\u003c\/strong\u003e, \u003c\/a\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/damp-proof-mesh-membrane-platinum-dm3\" target=\"_blank\"\u003ePlatinum DM3\u003c\/a\u003e\u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/damp-proofing-membrane-dm2\" target=\"_blank\"\u003e\u003c\/a\u003e\u003c\/strong\u003e and \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/damp-proof-membrane-pm3\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum PM3\u003c\/strong\u003e\u003c\/a\u003e, and can also be used universally with compatible systems from other manufacturers, including \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/damp-proof-membrane-non-mesh-newton-803\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eNewton Newtonite\u003c\/strong\u003e\u003c\/a\u003e, \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-damp-proof-membrane-803-newtonite\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eNewtonite Lath\u003c\/strong\u003e\u003c\/a\u003e, \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/damp-proof-membrane-platon-pb2\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003ePlaton PB2 Mesh Membrane\u003c\/strong\u003e\u003c\/a\u003e, \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/wykamol-cm3-waterproof-membrane\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eWykamol CM3\u003c\/strong\u003e\u003c\/a\u003e and \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/wykamol-cm3-mesh-membrane\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eWykamol CM3 Mesh Membrane\u003c\/strong\u003e\u003c\/a\u003e.

Available in 60mm and 90mm lengths, the plug expands when the supplied central pin is driven into place, helping create a secure fixing in poor-quality base materials such as cob, soft historic brickwork, deteriorated blockwork and friable stone.

Standard fixing plugs rely on friction between the plug body and the surrounding masonry to create anchorage. In weak, soft or friable substrates, this friction is often insufficient and the plug can loosen or pull out during or after membrane installation. Platinum Cob Plugs address this directly by incorporating a supplied central pin that is driven into the plug body after insertion, physically expanding the stem inside the drilled hole. This mechanical expansion creates a much stronger grip in poor-quality base material, making the plugs reliable in situations where conventional membrane fixings consistently fail, particularly on cob walls, soft historic brickwork and deteriorated masonry.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Where can Platinum Cob Plugs be used in damp proofing work?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Cob Plugs are designed for above-ground damp proofing applications where the wall substrate is too weak, soft or friable for standard fixing plugs.

Standard mesh membrane plugs are suitable for reasonably sound masonry such as standard modern brick, dense blockwork and concrete where a straight plug achieves adequate grip. Platinum Cob Plugs are the correct choice where the masonry is soft, deteriorated or irregular, including cob construction, soft historic brick, friable stone and poorly bonded blockwork. If there is any doubt about whether the substrate will hold a standard fixing, the expanding-stem action of the Cob Plug provides a more dependable mechanical solution for holding the damp proof membrane securely against the wall.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the main advantages of Platinum Cob Plugs?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Cob Plugs offer a strong combination of practical advantages for damp proofing work on difficult substrates.

The 60mm plug, drilled to approximately 65mm, is suited to situations where the substrate is of moderate quality for a cob-style plug and where the shorter embedment provides sufficient grip for the membrane being secured. The 90mm plug, drilled to approximately 95mm, provides significantly greater embedment and is better suited to more severely deteriorated, soft or unreliable substrates where deeper anchorage is needed to hold the membrane reliably against the wall. The 90mm version is the natural choice wherever any doubt exists about substrate quality or where particularly challenging masonry conditions are encountered during installation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How are Platinum Cob Plugs installed correctly?\u003c\/h3\u003e\n\u003cp\u003eA) To install Platinum Cob Plugs correctly, first inspect the substrate and confirm the membrane is correctly positioned on the wall.

This broad compatibility makes them a practical fixing option for installers working across different damp proofing membrane brands, particularly on challenging substrates where expanding plug anchorage is needed. Suitability for each specific membrane system and project should always be confirmed against the relevant manufacturer’s guidance and installation instructions before work begins.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What substrates are Platinum Cob Plugs suitable for?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Cob Plugs are designed specifically for weak, friable, undulating or low-density wall substrates where standard fixing plugs are unreliable. Suitable backgrounds include cob construction commonly found in older UK properties, soft historic brickwork that has deteriorated through age, lime mortar movement or moisture exposure, deteriorated blockwork where the block composition is too soft for straight plug grip, and certain friable or irregular stone backgrounds where mechanical expansion can still create useful anchorage. The substrate must be capable of accepting a 10mm drilled hole and retaining the expanded plug stem after pin installation. Where masonry is so severely crumbled or structurally compromised that it cannot support any fixing, localised repairs should be carried out before membrane installation proceeds.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Are there practical tips for getting the best results when installing Platinum Cob Plugs?\u003c\/h3\u003e\n\u003cp\u003eA) For the best results when installing Platinum Cob Plugs, inspect the substrate carefully before starting and carry out localised repairs on severely crumbling or unstable masonry. Select the appropriate plug length based on substrate quality, using the 90mm plug wherever conditions are particularly poor.

Position the membrane carefully before drilling to ensure the fixing layout achieves the recommended 16 plugs per m² density.

After driving the central pin, check each plug is firmly seated and the membrane is held tightly and evenly against the full wall area before finishing.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the limitations of Platinum Cob Plugs?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Cob Plugs have several important limitations to be aware of. They are designed for above-ground damp proofing membrane fixing and are not suitable for below-ground cavity drain waterproofing applications where a sealed watertight fixing is required. While the expanding-stem action improves grip in weak substrates, the plug still requires the masonry to be stable enough to accept a 10mm drilled hole and retain the expanded stem. Severely crumbling or structurally compromised walls must be repaired before installation. The central pin must be fully driven into the plug to achieve the intended expansion, as partial insertion will result in reduced anchorage. They are not general-purpose wall plugs and should only be used within their intended damp proofing membrane system context.\u003cbr\u003e\u003c\/p\u003e","brand":"Platinum Building Chemicals Ltd","offers":[{"title":"(W) M10 x (L) 60mm \/ Box of 200","offer_id":8107725324387,"sku":"BWA36","price":24.95,"currency_code":"GBP","in_stock":false},{"title":"(W) M10 x (L) 60mm \/ Box of 50","offer_id":7653468766238,"sku":"BWA36-50","price":8.95,"currency_code":"GBP","in_stock":false},{"title":"(W) M10 x (L) 60mm \/ Box of 100","offer_id":8010560438302,"sku":"BWA36-100","price":14.95,"currency_code":"GBP","in_stock":false},{"title":"(W) M10 x (L) 90mm \/ Box of 200","offer_id":8107728732259,"sku":"BWA37","price":26.5,"currency_code":"GBP","in_stock":true},{"title":"(W) M10 x (L) 90mm \/ Box of 50","offer_id":8107728044131,"sku":"BWA37-50","price":9.25,"currency_code":"GBP","in_stock":true},{"title":"(W) M10 x (L) 90mm \/ Box of 100","offer_id":8107728699491,"sku":"BWA37-100","price":15.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/platinum-cob-plugs-w-m10-x-l-60mm-box-of-200-damp-proof-membrane-ancillaries-137.webp?v=1780572185","url":"https:\/\/www.platinumchemicals.co.uk\/products\/platinum-cob-plugs-expanding-damp-proof-membrane-fixings","provider":"Platinum Chemicals","version":"1.0","type":"link"}
