THE SOLUTION

Repiper develops and markets tools for entrepreneurs interested in the renovation or reinforcement of a buildings old, worn plumbing joints.

ABOUT

Repiper develops and markets tools for entrepreneurs interested in the renovation or reinforcement of a buildings old, worn plumbing joints, in an environmentally friendly, cost and time efficient manner.

Repiper’s tools are used by contractors renovating buildings’ plumbing. Repiper’s joint reinforcent tool for renovating a buildings’ plumbing system by using trenchless rehabilitation, are based on a lining with a felt-reinforced flexible lining, impregnated with curing plastic (thermosetting polymer). When the liner is cured, new pipes are created inside the existing pipes.

The use of felt-reinforced flexible linings originates from the 1960s, making it the most accepted technology on the market for renovating buildings’ worn and damaged plumbing systems.

Our tools are patented and custom made and is used by contractors and installers in both regional and international markets. The number of people working with the tool is continually increasing.

Property owners can contact our network of tool users to obtain a quote for renovating or reinforcing a buildings old, worn plumbing system. Entrepreneurs are welcome to contact us for more information about the tool as well as our other products.

REPLACE OR RENOVATE?

A traditional plumbing replacement in a property has historically meant a lot of inconvenience for the residents.

During a traditional pipe replacement tenants will be evacuated from the property in order to avoid the noise and dust that a traditional plumbing replacement creates. A traditional plumbing replacement often includse various environmental hazards, such as asbestos and lead.

Many of these inconveniences can be avoided by renovating a buildings plumbing system with ‘trenchless rehabilitation’ instead. Neither the floors, nor the walls are broken up when lining, meaning that the disturbance
will be minimal – and the entire process only takes a few days. When renovating by using lining it is possible to use the building as normal during the short period of work in progress.

In the table, a comparison is made between replacing a building’s plumbing or lining it, or coating it:

PREPARATIONS

Certain preparations must be made in order for the renovation of plumbing, by using the lining technology, to be effective, secure and of good quality. 

Inspection
The buildings’ plumbing is first inspected by using a video camera to analyse its remaining service life and the condition of the system. By analysing the video, an assessment can be made to conclude whether further measures are required or not.

Work planning
In those cases where sliplining will be implemented, planning begins on how the work will progress. The goal of the work planning is to schedule the work, based on the prerequisites of the object, so that it can progress smoothly, quickly and with minimal disruption to the tenants.

Cleaning the buildings’ plumbing
During the lifespan of a buildings’ plumbing, deposits get stuck on the insides of the pipes. Prior to sliplining, buildings’ entire plumbing are being cleaned.

Preparations of the workplace
Before beginning the sliplining, it is important to prepare the workplace. This means having access to electricity, water and air, and to make sure that the work areas are covered with protective material and tools and machinery are in place.

Get the linings ready
The curing plastic used in the process consists of two components: one resin component and a hardener. When the two components are mixed an irreversible chemical process begins that hardens the plastic.

The felt-reinforced flexible lining is then soaked with the ready-to-use curing plastic before it is set to be installed in the buildings’ existing, old plumbing.

LINING THE SOIL STACK

After the felt-reinforced flexible lining has been soaked with curing plastic it is pressed into the pipe with the help of compressed air and the old pipe is used as a cast.

The flexible lining is kept inflated while the plastic hardens. When the new stack is finished, holes are milled out for the branch linings.

A short video to explain this part of the process.

LINING THE BRANCH PIPES

Connections between the branches and the soil stacks are especially exposed areas. They are the part of buildings’ plumbing which is most often affected by cracks and leakages. A custom-made flexible branch lining that has been soaked with the curing plastic is therefore installed at the transfer point between the stack and branches.

This procedure makes the branches properly reinforced, and future problems are prevented.

LINING THE BRANCH LINES

When the soil stack has been lined and the branch connections has been reinforced, the branches from the kitchen and bathroom are being connected to the soil stack.

LINING THE MAIN DRAIN

When the building’s entire plumbing has been renovated, the work is completed by lining the main drain from the building to the sewage network of the city.

When the work has been completed, new plumbing has been created throughout the entire building in a very short period of time. With regular maintenance, these pipelines will work without any problems for a foreseeable future.
