Conventional solutions are limited to:

• Conventional coatings - Chemical resistance• Fiberglass linings - Poor adhesion/flexibility• Chemical-resistant tiles - Expensive/grouting attacked

Belzona can provide solutions to common problems found in plants including:

Concrete repair

Application DetailsDamaged concrete removed and reinforcement bar encapsulated.Belzona 4000 series product used to rebuild and protect against further chemical attack.

EquipmentChemical reactor support base

CompanyPetrochemical plant, Czech Republic

Concrete base repair andprotection

Application DetailsApplication was carried out in accordance with the modified version of Belzona Know-How System Leaflet TCC-8. The irregular shim was created by filling the gaps between vessel heels and concrete supports with Belzona 4111. Belzona application was fast, providing excellent adhesion to different substrates together with excellent chemical protection.

EquipmentProcess vessel (mixer) in chemical production.Uneven gaps (up to 70 mm) and additional deterioration of the concrete supports under mixer heels caused by chemical attack.

EquipmentChemical sump around the rail car cleaning area

Application DetailsOld tiles and coatings had failed due to the steam and hot water. Belzona 4181 provides outstanding resistance to chemicals and heat.

Sump repair

CompanyChemical plant, UK

EquipmentChemical sump - hydrochloric acid was seeping into a nearby water course. The problem was tracked down to a sump where hydrochloric acid had eaten through the concrete.

Application DetailsWith the use of heaters, the hole was repaired and the sump protected with Belzona within the allowed three-day time frame. Still performing as expected – problem totally solved.

Problem

Application Details

Belzona repairs attacked channels

Chemical plant, France

Concrete channel attacked by mixture of chemicals, leading to contamination of the environment.

Due to the short window to realise the repair, Belzona products were selected. After repairing the concrete channel using a former, Belzona 4000 series coatings were applied to protect from further chemical attack.

Problem

Application Details

Belzona repairs attacked channels

Power station, UK

Failure of the channel’s existing bituminous screed.

The existing screed was removed before applying Belzona 4181. Belzona proved to be the ideal alternative for its ease of use and level of performance offered. The application was done in 2001 and an inspection in 2007 showed no sign of degradation.

Problem

Application Details

Belzona repairs attacked channels within a minimum of time

Chemical plant, France

Channel initially protected by tiles. Grouting and tiles attacked by chemical mixture (caustic + acids), resulting in damage.

A metal channel was created and coated in a workshop with Belzona 4000 series coating. The box was then bonded in place using Belzona 4000 mortar products. It took the customer only 2 days to repair the channel before starting production again!

Problem

Application Details

Belzona protects chemical containment area

Food processing plant, France

Heavy deterioration of concrete due to leakage and contamination.

Application was carried out in accordance with Belzona system leaflet TCC-15. Special attention was given to shimming and protection of the base of support steel. The area is now meeting required regulations. During inspection in 2009, the coating was still in perfect condition.

Problem

Application Details

Belzona protects existing tiles

Tiled bund area at a water treatment plant

Gas scrubber HCI/NaOH containment area damaged and acid-resistant tiles failed.

Following thorough cleaning all tile joints and damaged areas repaired using Belzona 4141 (Magma-Build) followed by the application of Belzona 4311 (Magma CR1) to provide a seamless acid-resistant finish.

The system provides long term protection to the containment area and is easily repaired in the event of localised mechanical damage.

Problem

Application Details

Belzona protects sulfuric acid bund

Sulfuric acid refinery, USA

Previous coating gave limited results.

Replacement of the concrete containment area was not an option due to downtime. Belzona 4000 series products were used to rebuild and protect the concrete (80m2). Coating was still OK after 2 weeks where other coatings failed after 48 hours.

Problem

Application Details

Belzona protects caustic containment area

Water treatment plant -power plant, USA

Previous coating had failed and the customer needed to install a new impervious coating.

Old coating removed with high pressure water blasting. Belzona 5000 series was applied to containment area and tank stands. The customer trusted the product and longevity of previous applications
