12MM DPC Injection Plugs for a Clean and Professional Finish
12mm DPC injection plugs are designed to seal drilled holes after the installation of a chemical damp proof course. Once the injection stage is complete, these plugs provide a simple and effective way to finish the treatment line neatly, helping to improve the overall appearance of the wall while keeping the job looking clean and professional.
When carrying out remedial damp proofing work, the finishing stage is just as important as the treatment itself. Open or poorly filled injection holes can leave a job looking incomplete, especially on visible masonry. These 12mm DPC injection plugs offer a straightforward solution, allowing you to close off the drilled holes quickly and consistently without the need for mixing and applying sand and cement.
Supplied in a 100 pack, they are ideal for DIY’ers, damp proofing contractors, builders, maintenance teams, and property renovators who want a practical, easy-to-use finishing product for DPC work. They are suitable for drilled holes in brick and mortar and can be used after applying chemical damp proofing creams or fluids as part of a rising damp treatment system.
Why Choose 12MM DPC Injection Plugs?
Quick and Easy to Fit
One of the main advantages of these 12mm DPC injection plugs is how quick they are to install. Once the damp proofing product has been injected, the 12mm DPC injection plugs can be inserted directly into the prepared holes by hand. This makes them a fast and convenient option on site, especially when compared with traditional hole filling methods.
Neater Than Sand and Cement Filling
For many installers, speed matters, but appearance matters too. These 12mm DPC injection plugs help create a tidier finish along the injection line and reduce the need for hand-filling each individual hole with mortar or patching material. This can save time while also giving the treated area a more uniform, consistent look.
Suitable for Damp Proofing Injection Work
These 12MM DPC Injection Plugs are intended for use after chemical DPC installation, making them a practical finishing component for damp proofing injection systems. They are ideal for sealing drill holes once the injection process is complete and the wall no longer requires access for product application.
Practical for Trade and DIY Use
Whether you are working on a full remedial damp proofing injection contract, a single wall treatment, or a smaller repair job, a 100 pack of 12mm DPC injection plugs is a useful quantity to keep on hand. They are suitable for professionals and experienced DIY users alike.
