Crack Filling Paste
TM Riftplug
The final prep step before waterproofing begins.

Overview
TM Riftplug exists for one specific moment in a project: after a crack has been identified on a cement surface, and before any waterproofing coating or membrane is applied over it. Sealing a coating over an unfilled crack just relocates the failure point — this fills it first.
It's ready to use straight from the pail, worked into cracks and masonry gaps with a trowel or putty knife, and formulated to stay flexible rather than turning brittle and re-cracking once the waterproofing layer goes on top of it.
Because it's positioned explicitly as the final prep step before waterproofing, it's the product that opens most treatment jobs on a cracked or damaged surface — everything else in the range assumes the substrate has already been through this step.
Key features
- Ready to use — no mixing required
- The final prep step before any waterproofing coating goes on
- Flexible repair — resists re-cracking under the coating above it
- For concrete and masonry cracks
- Small-format pail suited to spot repairs and touch-up work
