Universal DPC Injection Plugs are a practical and essential component in any chemical damp proofing system, offering a simple yet reliable solution for sealing drilled holes following damp proof course (DPC) injection. By closing off injection sites in masonry, these plugs prevent the ingress of moisture, dust, and insects, helping to protect the integrity of the treated wall. Their primary function is to support the performance of the chemical DPC by maintaining an airtight seal, allowing the injected material to cure undisturbed within the masonry structure.
Engineered to fit standard 10mm and 12mm drilled holes, Universal DPC Injection Plugs are compatible with a wide range of injection systems commonly used in the damp proofing industry. Their tapered design ensures a secure and snug fit within the hole, eliminating the risk of the plug loosening or falling out over time. This tight seal also reduces internal air movement, which is crucial for promoting optimal curing of damp proofing products and preventing evaporation or displacement.
Manufactured from robust and non-degrading plastic, these plugs are designed for long-lasting performance in various environmental conditions. Their weather-resistant properties ensure they remain intact and effective, even in damp or fluctuating temperature environments. The use of high-quality plastic materials also ensures a consistent seal over time, helping to uphold the effectiveness of the chemical treatment and prevent secondary issues from developing.
A key benefit of the Universal DPC Injection Plugs is their availability in multiple colour options, allowing users to select plugs that best complement the surrounding brick or mortar tones. This feature is particularly valuable in projects where visual appeal is important, such as heritage restorations or exposed brick interiors. The ability to blend the plugs into the existing façade ensures a discreet and professional finish.
Supplied in bulk or smaller pack sizes, these injection plugs are suitable for both individual treatments and large-scale damp proofing contracts. They can be easily installed without the need for specialist tools, making them a practical choice for contractors, builders, and remedial professionals. Whether used in residential renovations or commercial maintenance, Universal DPC Injection Plugs provide a clean, effective, and aesthetically pleasing solution for sealing damp proofing injection sites.
Compatible with Standard DPC Drill Sizes: Designed to fit snugly into 10mm or 12mm diameter holes, making them suitable for use with most chemical damp proofing systems on the market.
Tapered for a Secure Fit: The tapered body ensures a tight and secure hold within the drilled hole, helping to prevent displacement over time.
Range of Colour Options: Available in five colours—terracotta, light grey, dark grey, buff, and brown—allowing for improved visual integration with the substrate.
Quick and Easy to Install: No specialist tools are required. The plugs can be pressed or gently tapped into place, making them convenient for both professionals and DIY users.
Durable Plastic Construction: Made from hard-wearing plastic, the plugs resist environmental exposure and offer long-term reliability in both internal and external walls.
Prevents Ingress: Sealing the injection points helps to stop water, dirt, and insects entering the cavity, supporting the integrity of the DPC system.
Post-injection Capping of DPC Holes: Used after applying damp proofing creams or fluids to close drilled holes in brick or mortar walls and prevent disturbance of the chemical treatment.
Use in Both Internal and External Walls: Suitable for sealing drill points in a range of building environments, including internal partition walls and external elevations.
Conservation and Heritage Properties: The range of colour options makes these plugs ideal for use where visual blending with traditional brick or stonework is required.
General Masonry Repair and Damp Control: Applicable in any scenario where damp proofing holes need to be closed cleanly and effectively after treatment has been completed.
Universal DPC Injection Plugs are suitable for use in most common masonry materials, including brick, block and mortar. They are specifically designed for holes drilled during the installation of chemical damp proof courses using either cream-based or fluid injection systems.
The plugs can be used internally or externally, providing a neat and effective finish to drilled injection points once the DPC treatment is complete.
Before inserting the plugs, ensure that all drill holes are free from excess damp proofing product, debris, and dust. Any residual material should be carefully cleaned from the surface of the hole using a clean cloth or compressed air if available.
The plug should be inserted only once the injection process has been completed and the hole is no longer in use for chemical application.
Select the correct plug size for the drilled hole, either 10mm or 12mm in diameter depending on the damp proofing system used. Match the colour of the plug, where desired, to the surrounding brick or mortar for a more discreet finish.
Insert the plug into the hole by hand, pushing firmly until it sits flush with the surface. If required, a rubber mallet or similar tool may be used to gently tap the plug into place, taking care not to damage the plug or surrounding masonry.
Universal DPC Injection Plugs are intended solely for use as a physical closure to DPC injection holes. They are not a substitute for chemical damp proofing treatments but are an important component in delivering a tidy, sealed finish after injection.
The plugs help to reduce air movement through the wall and prevent the ingress of water, insects or dirt into the treated area. They are available in multiple colours and pack sizes, providing flexibility for projects of all sizes. Proper sealing of DPC holes supports the long-term performance of the damp proofing system and improves the appearance of finished work.
