RiveStop 8 bar - mechanical sealing plug for concrete (stainles steel)

The RiveStop 8 bar is a mechanical sealing plug designed for permanently closing formwork tie-rod holes in concrete structures. It provides a watertight seal up to 8 bar of hydrostatic pressure. 
It is available with stainless steel outer washer. 

Usage:

• Suitable for sealing tie-rod holes (from formwork) in cast-in-place concrete walls where waterproofing is required.

• Applicable in new construction or refurbishment, in structures such as basements, water retention tanks, tunnel linings, parking garages, etc.

• The mechanical rivet system expands inside the hole and locks into the structure, creating a permanent seal.

How it works:

1. Insert the RiveStop unit into the prepared tie-hole (diameter as per specification).

2. Use a rivet tool (manual or electric) to activate; the internal mandrel breaks off when the correct expansion is achieved. 

3. The rubber body expands (~50% of its original diameter) pressing uniformly against the hole walls, forming the seal. 

Benefits:

• Provides a reliable watertight seal with minimal human variability. 

• Quick installation: only a few seconds per hole.
  

Safety and use-recommendations:

• Ensure hole diameter, length and installation tool are compatible with the specific RiveStop reference. 

• Store in original packaging, protected from direct sunlight and moisture until use. 

• Installation should follow manufacturer’s guidelines to ensure full expansion and correct activation.

• Although rated to 5 bar, it is important to consider site conditions (chemical exposure, movement, temperature) and check compatibility with concrete/water environment.

Technical Specifications (example ranges):

• Rated hydrostatic pressure: up to 8 bar for the 8 bar version.

• Hole diameter range: suited for inner hole diameter 17.5-28 mm. 

• Materials: Rubber body, aluminium rivet/mandrel, outer washer stainles steel.
