Renovation

Renovation is a future-proof choice

Most of the water and sewage infrastructure in Europe are nearing the end of their service life. Numerous investment projects in 1970s and 1980s were based on reinforced concrete, steel and cast iron pipes, which now need continuous repair, renovation or replacement. While repair is a temporary solution and replacement an expensive one, renovation seems a reasonable compromise. Such projects involve, among others, different renovation methods by means of polyethylene pipes.


Uponor Infra is one of the most experienced manufacturers and suppliers of polyethylene pipes since its history goes back to 1950s. Since 1976 the company has also developed pipe systems for renovation of damaged pipelines, used for repairing water pipelines as well as sewage pressure and gravity systems or technological pipelines.


The renovation methods using Uponor Infra systems have become one of the most reliable technologies in the market. The fact that the pipes are made of polyethylene has got numerous benefits. The renovated canal or pipeline is corrosion, abrasion and impact resistant, guarantees long-term operation and is characterized by low roughness coefficient ‘k’. These methods of renovation require installation trenches only, which helps minimize car and pedestrian traffic disturbance. What is more, during the renovation process water and sewer system can normally operate and – in most cases – there is no need for drainage.

Gravity renovation

Prior to renovation works, an in-depth analysis of pipeline technical condition is required. Before choosing a particular renovation method one must:

 

  • determine the structural and hydraulic condition of the damaged pipeline
  • assess degree of damage to the pipeline
  • prepare a detailed calculation of pipeline parameters, including location, side connections, dimensions and material used to build it
  • choose the most optimal renovation method.

 

Uponor Infra can offer a range of several renovation technologies:

  • long relining (sliplining) and short relining with Weholite pipes,
  • short relining and static cracking with VipLiner module,
  • long relining (slipliningu) with WehoPipe and WehoPipe RC/RC+

Culvert renovation

We propose Weholite pipes, used for a long time in the road construction, for the renovation of road culverts. Road culverts built in Weholite technology have very high dynamic load resistance. The properties of their construction material, i.e. polyethylene, give them long service life, complete lack of corrosion and high chemical resistance (inter alia to oil derivatives, salts). Weholite culverts are made from double-wall pipe which ensures high ring stiffness. The pipes are admitted for use in the mining damage areas up to 4th category (inclusive).

 

Weholite culverts installed in many European countries are an alternative to traditional materials. The culverts are used both under the roads and the railway tracks. Weholite culverts became a standard in road construction in Europe, and specifically in Scandinavia, as the polyethylene is a completely environment friendly material.

 

The type of the road and soil should be considered when designing the road culverts and selecting the suitable ring stiffness of the pipes. The guidelines and approvals of e.g. the Railway Lines Administration apply to the installation of culverts under the railway tracks.

 

Weholite culverts can be installed both with small and very big overburden. The ends of the culverts can be formed in any way accordingly to the inclination of the slopes. Weholite culverts are offered in a very extensive range of diameters, from 300 mm to 3000 mm and in a standard 12.5 m length. At client’s request we can make the culverts of any diameter, length and ring stiffness.

Chamber renovation

The analysis of technical condition of a collector should comprise the manholes along its route. Their technical condition may also pose the same threats as the collector itself. Even if, before renovation, no infiltration of ground water in the manhole was found, after the collector is tightened, the ground water level may rise and leaks may occur. That is why in the areas characterized by a high level of ground waters, it is worth renovating not only the collector but also the manholes.

 

Sewage manholes are always renovated by means of readymade Weho manholes, suited to the size of repaired chamber. Weho manholes are manufactured to an individual project and may be customized to atypical orders. Weho manholes allow to create in result a complete, unified system of pipes, manholes and fittings.
