Newton CDM MultiPlug Pins
Newton MultiPlug Pins (Newton product reference A4) are accessory pins used with Newton CDM MultiPlugs to improve fixing strength in weak, friable or unreliable substrates. They are not standalone fixings and should only be used in conjunction with Newton MultiPlugs.
Once inserted into the hollow body of the MultiPlug, the pin expands the plug’s outer circumference by nearly 2mm, tightening it into the drilled hole and improving grip within poorer base materials.
Newton MultiPlug Pins are particularly useful where the standard MultiPlug has not achieved a sufficiently firm hold in soft brick, crumbling masonry, low-density blockwork, friable concrete or weak stone. They are an optional extra for more difficult substrate conditions within Newton cavity drain membrane installations.

Key Features of Newton CDM MultiPlug Pins
✔️ Accessory pins used with Newton CDM MultiPlugs to improve fixing strength in weak or friable substrates.
✔️ Expands the MultiPlug outer circumference by nearly 2mm, tightening the fixing inside the drilled hole.
✔️ Converts the standard MultiPlug into an expanding fixing for improved grip in poor-quality base materials.
✔️ Useful on soft brick, crumbling masonry, low-density blockwork, friable concrete and weak or deteriorated stone.
✔️ Not a standalone fixing, used selectively where a standard MultiPlug has not achieved sufficient anchorage.
Expanding Anchorage Pins For Newton CDM MultiPlugs In Weak Masonry Substrates
Newton MultiPlug Pins are specialist accessory components developed for use within the Newton Cavity Drain Membrane System, designed specifically to improve the anchorage of the Newton CDM MultiPlug when fixing waterproof cavity drain membranes to substrates that are weak, friable, soft, low density or otherwise difficult to fix into reliably. The pin does not fix a membrane independently, but instead works by being inserted into an already fitted Newton MultiPlug, forcing the plug body outward within the drilled hole and creating a noticeably tighter mechanical grip against the surrounding substrate material. This simple but effective action can make a meaningful difference to fixing performance in backgrounds that would otherwise struggle to retain a standard membrane plug securely.
Expanding The MultiPlug Body By 2mm For Improved Mechanical Grip
The primary function of the Newton MultiPlug Pin is to convert the standard Newton MultiPlug into an expanding fixing capable of generating greater friction and resistance within the drilled hole. When driven fully into the plug, the pin expands the outer circumference of the MultiPlug by nearly 2mm, pressing the plug body more firmly against the sides of the hole and increasing the mechanical resistance holding it in place. This can make a significant practical difference in substrates where the base material is too soft or crumbly to retain a standard plug reliably, including deteriorated brickwork, older blockwork, friable stone, weak concrete or masonry affected by age, prolonged moisture exposure or previous building movement.
Selective Problem-Solving Accessory For Variable Substrate Conditions On Site
Newton MultiPlug Pins are used selectively rather than as a standard part of every fixing, typically deployed when an installed MultiPlug feels loose, spins, pulls out too easily or simply fails to grip the substrate with sufficient confidence. Their role is purely to improve anchorage within the substrate, with no effect on the waterproofing detail, membrane seal or the sealing washer function of the MultiPlug itself. This makes them a valuable problem-solving accessory on basement waterproofing, cellar conversion and cavity drain membrane installations where substrate quality can vary considerably across the same wall. Where masonry is extremely poor and even a pinned MultiPlug cannot achieve a reliable hold, a purpose-made expanding fixing such as Platinum Cob Plugs may be a more appropriate solution.

Product Benefits
-
Improved Grip In Weak Substrates: Newton MultiPlug Pins expand the Newton MultiPlug by nearly 2mm, helping tighten the fixing inside soft, friable or low-density masonry where a standard plug may not grip securely enough.
-
Designed Specifically For Newton MultiPlugs: The pins are made to work with the hollow body of the Newton CDM MultiPlug, converting it into an expanding fixing without changing the intended membrane fixing method.
-
Useful Corrective Fixing Accessory: The pin can be inserted after the MultiPlug has been fitted if the fixing feels loose or unreliable, giving installers a practical way to improve anchorage without immediately replacing the fixing detail.
Typical Applications
-
Weak Or Friable Masonry Fixing: Newton MultiPlug Pins are used where Newton MultiPlugs need extra anchorage in crumbling brickwork, soft blockwork, friable stone or weak concrete during cavity drain membrane installation.
-
Basement Waterproofing Membrane Installations: Suitable for Newton CDM System projects where substrate quality varies across retaining walls and certain MultiPlug fixings need additional expansion to achieve a firmer hold.
Q) What are Newton MultiPlug Pins used for?
A) Newton MultiPlug Pins are used to improve the fixing strength of Newton CDM MultiPlugs when installing Newton cavity drain membranes onto weak, friable or unreliable substrates. They are not standalone membrane fixings and should only be used with Newton MultiPlugs. Their purpose is to tighten the plug inside the drilled hole where the substrate is too soft, crumbly or low density to give a reliable hold on its own. Once inserted into the hollow body of the MultiPlug, the pin expands the plug’s outer circumference by nearly 2mm, improving grip and helping the fixing stay secure in difficult masonry, soft brick, friable concrete, weak stone or older blockwork.
Q) How do Newton MultiPlug Pins work with Newton CDM MultiPlugs?
A) Newton MultiPlug Pins work by turning the Newton CDM MultiPlug into a stronger expanding fixing. The standard MultiPlug is first installed through the membrane and into the drilled substrate in the usual way. If the fixing does not grip firmly enough, the Newton MultiPlug Pin is inserted into the hollow body of the plug. As the pin is driven in, it forces the plug body outward and expands the outer circumference by nearly 2mm. This extra expansion increases contact pressure against the sides of the drilled hole, helping improve friction and mechanical resistance. The result is a tighter, more secure fixing in weaker base materials.
Q) When should Newton MultiPlug Pins be used?
A) Newton MultiPlug Pins should be used when a Newton CDM MultiPlug has not achieved a firm enough fixing in the substrate. They are particularly useful when working into soft brick, crumbling masonry, low-density blockwork, friable concrete, weak stone or older materials affected by age, moisture or deterioration. In practice, they are normally used selectively rather than with every plug. If a MultiPlug feels loose, turns in the hole, pulls out too easily or fails to grip properly, the pin can be inserted to improve anchorage. This makes Newton MultiPlug Pins a practical corrective accessory on basement waterproofing and cavity drain membrane installations where wall quality varies.
Q) Are Newton MultiPlug Pins waterproof membrane fixings by themselves?
A) No, Newton MultiPlug Pins are not waterproof membrane fixings by themselves and should never be used as standalone fixings. They are accessory pins designed only for use with Newton CDM MultiPlugs. Their job is to improve the anchorage of the MultiPlug in weak or friable substrates, not to seal the membrane, replace the plug, or create a waterproof fixing detail on their own. The membrane fixing and sealing function still comes from the correct Newton MultiPlug installation and associated sealing washer or system detail. Newton MultiPlug Pins simply improve the mechanical hold of the plug where the drilled substrate is not giving enough grip.
Q) What are the limitations of Newton MultiPlug Pins?
A) Newton MultiPlug Pins are only suitable for use with Newton CDM MultiPlugs and should not be treated as a universal fixing pin for other plugs or membrane systems. They improve grip by expanding the MultiPlug, but they do not repair unsound masonry, replace proper substrate preparation, or guarantee a secure fixing in severely crumbling backgrounds. They also do not alter the waterproofing design or seal the membrane penetration. If the wall is extremely soft, unstable or too friable for a pinned MultiPlug to hold properly, a more suitable expanding fixing such as Platinum Cob Plugs may be required. The installer should always check the fixing strength before continuing with finishes.
