The DPC Injection Plug caps the hole so there is no need to plug with other materials such as cement or grouts. These plugs can be used to fit both 10 and 12 mm holes. When installed, the DPC Injection Plug creates a colour-matched seal to complete the job. Our DPC plugs are available in grey, white or red/terracota Available in 1000's Grey, White or Terracotta Suitable for 10 and 12 mm holes
