OVK Group successfully completes warehouse refurbishment project in Gqeberha

The OVK Group, a leading agricultural company headquartered in Ladybrand, South Africa, has showcased its commitment to progress with the completion of a significant warehouse refurbishment project Gqeberha. The project, executed by a collaborative team of experts, marks OVK’s continuous efforts to expand and enhance its services for all stakeholders.

Addressing an imperative concern, the OVK Warehouse rejuvenation project tackled the challenge of moisture ingress affecting the structural columns. The issue of serious spalling demanded swift intervention, which was expertly provided by Altrama, the engineering team responsible for the project. Geotech SA, the main contractor, lent their expertise to ensure the project’s seamless execution.

The warehouse refurbishment involved a meticulous process. Initially, mechanical breakers were employed to remove damaged concrete, followed by comprehensive surface preparation to eradicate corrosion from the steel components. A key solution in the restoration was the application of Sika MonoTop®-1010 ZA a bonding Primer and reinforcement corrosion protection cement-based slurry containing corrosion inhibitors with reduced carbon footprint. The MonoTop®-1010 ZA was used as an anti-corrosion agent, onto the steel surfaces. This product showcased its effectiveness in preventing corrosion and enhancing the structural integrity of the columns. The Sika MonoTop®-1010 ZA was brush applied through two coats allowing to dry overnight.

To address the spalling, Sika MonoTop®- 412NFG was trowel-applied onto the concrete surfaces after the third application of wet Sika Monotop ®-1010 ZA acting now as a bonding agent, effectively executing the patch repairs. The Sika MonoTop®-412 NFG is R4 Repair Mortar with Corrosion Inhibitor ideal for this purpose. The comprehensive protection solution also encompassed the application of Sika® FerroGard®-903 Plus an active corrosion inhibitor for reinforced concrete, which was sprayed onto the entire column surface. This step extends the lifespan of the concrete while bolstering its durability.

In addition, a layer of SikaTop® Seal-107 ZA a liquid applied, cementitious waterproofing slurry was added to the steel components, augmenting the effective cover to the reinforcing elements. This comprehensive approach not only fortifies the structural elements but also exemplifies OVK’s dedication to quality and longevity.

The success of this refurbishment endeavor highlights OVK’s prudent decision-making. Opting for a refurbishment solution not only saved considerable time and resources compared to a complete rebuild but also minimised operational disruptions. This achievement is a testament to the meticulous planning and exceptional workmanship exhibited by Geotech SA, coupled with the seamless workability of Sika products.
