INSPECTION CHAMBERS - FACTS AND FICTION:
Traditional inspection chambers or manhole joints are usually made of concrete. The extent to which they remain watertight is dependent upon a number of factors. For example, chambers may not be able to resist the pressure caused by backed-up water. Localised cracking may occur and repairs are likely to be costly. Ground water can seep through these cracks and foul water and sewage effluent can escape. No one knows how much sewage enters the ground water through damaged inspection chambers, nor the quantity of ground water seeping into the sewerage system - placing added strain on sewage treatment plants. But everyone knows that our environment is under threat. Leaking inspection chambers pose a risk that should not be ignored.

The advantages of the ROMOLD polyethylene inspection chambers: they are extremely tough, 100 % watertight and can be used with all standard pipe joint connections and for all covers from Class A 15 through to Class D 400

The use of PE drainage systems has been limited to industrial sites and waste-dump drainage, where it has proved to be a viable solution to the problem of unwanted seepage. By contrast, many believe it to be too costly a solution for use in other drainage systems. Now, ROMOLD's vast know-how and experience in industrial production confirm PE inspection chambers as now only environmentally acceptable but also practical in economic terms for general application..

A drainage system is only as strong as its weakest link. Traditional inspection chambers often crack, damaging the environment

STATE OF THE ART TECHNOLOGY - NOT ONLY FOR PIPELINE SYSTEMS...
Plastic pipes are recognised as being highly durable, whether used in drainage systems or other applications. The polyethylene material used to manufacture ROMOLD system components meets all relevant standards. Site handling is optimised thanks to reduced component weight, especially in comparison to traditional concrete drainage materials. Whatever joints are used - welded or simple push-fit type - the connection is always guaranteed 100% watertight.

Plastic pipelines of various types are the present-day standard. Each type has undergone stringent testing over extended periods of time.

Plastic in drainage construction - out of sight, out of mind.
No matter how aggressive the ground or the sewage, polyethylene withstands both chemical attack and the mechanical stress from sand or coarse material contained in the sewage. The ROMOLD system reacts to natural movements of the earth and minor shifts in the stratum with maximum flexibility. Cracks and breaks are virtually a thing of the past. Not even the "thirstiest" tree roots are able to penetrate the synthetic material. A further advantage of polyethylene is its smooth surface. Organic materials and minerals can not adhere to the surface, ensuring that crusting and sediment formation is negligible.

...BUT ALSO FOR INSPECTION CHAMBERS
Up to now, using polyethylene materials for inspection chambers applications has meant prohibitively high production costs.

Computer aided design (CAD) is used to determine the stress points in the chamber base. This data is incorporated directly in new product developments.

The ROMOLD guarantee - 100% watertight chambers and reduced costs.
ROMOLD has pioneered the mass production of plastic inspection chambers and manholes. With its high-output production lines and wide range of components, ROMOLD provides the ideal high quality, cost effective alternative to traditional concrete inspection chambers. This is especially the case when 100% water tightness is required. The extensive range of off-the-shelf components can be supplemented with special parts made to customers designs and specifications. This is not all the system offers - it is lightweight, facilitating easy transportation and onsite handling, it is highly resistant to crack propagation and breakage, it is highly resistant to abrasion and it does away with the need for heavy-duty assembly equipment on the site. It reduces assembly times and it avoids the risk of legal liability as a result of faulty drain systems. What's more, all ROMOLD products last well beyond the term of the statutory guarantee, minimising maintenance costs for decades to come.

Mass production goes hand in hand with modularity: ROMOLD system chambers reduce costs and allow custom designs.

THE EASY DECISION: ROMOLD POLYETHYLENE DRAINAGE SYSTEMS
With the ROMOLD system, you plan as usual, taking all special site requirements into account. No specialised knowledge or tools are necessary for installing the system. The only difference to traditional systems is that the ROMOLD systems is easier to handle - no individual component weighs more than 70 kg. This means that ROMOLD drainage systems can be installed without the need for heavy-duty assembly equipment. In extreme applications, inspection chambers up to 12 meters in depth are available pre-assembled, welded and ready to use.

Detailed advantages: the ROMOLD system joint seal helps to avoid assembly errors and is 100% watertight, preventing external water from penetrating and internal water or effluent from escaping.

With ROMOLD you have a connection to the future
Plastic pipes can be easily connected to the openings in the inspection chamber base. Depending on the chamber base selected, prefabricated connections up to 400 mm diameter are available, meaning that all standard plastic pipes can be assembled completely and tightly at the construction site itself without the need for any specialised tools.

"Engineered to stay in place": once a ROMOLD inspection chamber has been installed, it remains in place. Special anti-lift features are also available for extreme applications.
