Concrete Repairs in the Water Industry

Posted: Friday 18th May 2012

Belzona provides a wide variety of polymeric repair products and protective coatings for buildings, structures, machinery and equipment. Such products have been used in the water/waste water industry for decades to combat common maintenance issues such as: chemical attack, abrasion issues, water leaks, corrosion, erosion, cavitation and water ingress.

Belzona’s long term repair solutions provide chemical resistant protective barrier coatings from the harsh environmental conditions that they are working within.

Concrete can be repaired and rebuilt quickly without any specialist tools or formers, using Belzona’s range of magma polymers.

By way of example, Belzona 4131 (Magma-Screed) a high performance concrete resurfacing product has been used to repair and fully encapsulate PST tank copings where the drive wheel runs on the top surface of the tanks. The range of Belzona concrete repair products have high compression and crush strength but also a high resistance to the chemicals used within the water industry.

The damaged areas of concrete were removed and brought back to a firm and dry substrate before the application of Belzona 4921 (Magma GP Conditioner). This product was applied to the damaged areas including all of the exposed metal reinforcement bars to provide a protective seal on the concrete and to prevent any further corrosion issues. Belzona 4131 (Magma-Screed) was then applied to the concrete surfaces to provide hard wearing protection against future attack. The repair composite was applied by hand into the damaged concrete areas and shaped back to the original specification/profile with a pointing trowel and metal float.

Belzona is also used regularly in the water/waste water industry to provide protective coatings for tanks, bunds, floors, walls and roofs. Most of these coatings are low odour and are fast curing to minimise the down time.
