A patented waterproofing system designed to completely seal form work holes formed by the removal of a taper tie rods from concrete walls. 

RIVEPIPE is the first removable, reusable and recyclable formwork tube designed to protect tie bars when they are inserted to form the wall.


Sanika Waterproofing Specialists are the exclusive distributor of RiveStop products in Southern Africa.

How it works

RIVEPIPE is adaptable to the thickness of the wall. Initially it can be installed during the construction of formwork for concrete walls, specially designed to protect tie bars when they are inserted to form the wall and to secure both sides of the formwork panels.

Aimed for creating a clean and empty concrete wall bushing, thereby avoiding the passage of moisture between the PVC tube and the concrete.

The extraction process is very quick (a matter of a couple seconds), very simple with the RIVEOUT extraction tool and without damaging the wall.

The result is a clean hole perfectly prepared for a hermetic seal with RIVESTOP and a more sustainable project committed to environmentally friendly construction.
