"The ultimate waterproofing solution"

RivePipe, the solution for extracting formwork tubes for reuse:

Removable

Reusable

Recyclable

RivePipe is an accessory for concrete formwork systems; it is a unique removable and reusable formwork tube for protecting the tie bars or Dywidag rods used to form concrete walls. It therefore prevents all risks of leakage through the tie hole if used together with our RiveStop product.

It is designed to pass through and protect the tie bars inserted to support both sides of the formwork panels and can be used for any wall thickness.

It can be removed fast and easily and can be reused for future formwork. It prevents leaving lost material inside the concrete wall and avoids the water leaks or humidity problems this could cause in the future.

It reduces on-site material and, apart from being reusable, it is also recyclable.

What are the advantages of RIVEPIPE for your project?

  • IT ELIMINATES THE RISK OF FUTURE LEAKS IN CONCRETE TIE HOLES
  • IT ELIMINATES THE RISK OF LOSING PLASTIC MATERIAL INSIDE THE CONCRETE WALL
  • IT REDUCES ON-SITE MATERIAL SPACE
  • IT MEANS SAVINGS IN MATERIAL AND LABOUR COSTS
  • IT MAKES THE WORK MORE SUSTAINABLE – GREEN BUILDING

Extraction is unbelievably fast, taking no more than seconds, and it is estimated that each tube can be reused at least 10 times. The wall remains intact. 1,000 RIVEPIPE tubes can be removed from the formwork holes in concrete walls and the tie holes sealed with RIVESTOP at the same time, by a single worker, and all in less than 3 hours. The workers don’t require special training or qualifications. Read more in the section on INSTALLATION.

 

How does it work? FAST, SIMPLE AND SAFE

RivePipe adapts to any wall thickness and is inserted previously, while assembling the formwork panels.

It consists of two parts joined to one another: a male and a female part, which are extracted from both sides of the wall once the concrete has dried and the formwork process is complete.

This is an innovative solution specially designed for extraction from the concrete wall (without damaging it) and reuse in another formwork project.

It creates clean, empty and homogenous tie holes, perfectly prepared for sealing with our RIVESTOP product.

On extracting the tube from the concrete, we eliminate the potential risks caused by leaks possibly caused due to the gap created between the external diameter of a conventional PVC pipe (which is normally left inside the wall) and the concrete, and the problems caused by leaving rigid materials inside the concrete. The behaviour of a lost rigid material (PVC tube) inside the wall and the concrete over the time is completely different, and this can cause a possible gap between the plastic and the concrete with time (contractions and dilatations of the concrete, earth movements, etc.). THEIR EXTRACTION IS UNBELIEVABLY FAST (IN ONLY A FEW SECONDS) AND SIMPLE USING THE RIVEOUT EXTRACTOR, YOUR ESSENTIAL ACCESSORY. READ MORE

The kind of RivePipe you should order will depend on the desired thickness of the wall in your project.

Depending on the wall thickness, the tube composition changes, always constituting a joint between one male and one female part. SEE TABLE

RivePipes are supplied in transparent plastic bags with a handle for easy use and transport, also permitting their reuse. Each bag contains 100 units.
