RiveStop is a patented elastic rivet with an internal mechanical waterproofing system designed to hermetically seal form tie holes in concrete structures.

RiveStop expands inside the formwork tie hole exerting force against the walls of the hole, thus sealing it completely. The mechanical system is activated with a riveter with uniform and controlled pressure. Once the pin of the rivet breaks off, the RiveStop is installed.


  • Huge saving on labour – 3 seconds to seal form tie holes
  • 100% watertight
  • Mechanical system – subsequent building movement will not affect the seal
  • Can be applied in all conditions

Comes in a variety of sizes and finishes
