Form Tie Plugs

Danterr’s Form Tie Plugs provide a simple and reliable solution for sealing form tie holes and spacers in concrete structures. Designed to prevent water ingress, they create a durable, watertight seal that helps protect concrete against moisture penetration.

The Form Tie Plug features a water-swellable thermoplastic rubber cap that expands when exposed to water, combined with a tough polyamide core that provides secure mechanical fixation. This dual-material design delivers reliable sealing performance while withstanding water pressure.

Designed for fast installation, Form Tie Plugs are inserted with a single hammer blow and require no additional finishing or after-treatment. The Form Tie Plugs suit common formwork spacer diameters, they are a practical solution for concrete waterproofing across civil, commercial and infrastructure projects.
