Spraylock Africa is revolutionising industrial floors with post-initial set applied colloidal silica, an innovative liquid densifier that strengthens concrete from within – a solution that drew the attention of Talita Thesnaar, a Stellenbosch University award-winning concrete researcher. She has remained fascinated by the wear and tear of industrial floors – particularly at joints – and has since dedicated her career to improving concrete performance and longevity.
After earning Stellenbosch University’s award for Best Final-Year Project in Concrete, she returned to the laboratory as a master’s student, where she is currently researching innovative treatments for concrete flooring. Her work encompasses testing liquid densifiers, finishing techniques, dry-shake hardeners, and experimental graphene-enhanced mixtures, each providing distinct insights into performance and durability.
These evaluations comprise abrasion, chloride penetration, stain resistance, and other durability assessments.
Among the products under investigation is SCP P3, a liquid densifier that extends beyond surface application, actively interacting with the concrete matrix.
While mechanical testing is ongoing, the product has demonstrated promising performance to date. These evaluations will further corroborate findings from other laboratory studies of colloidal silica. SCP P3 has already been applied to several landmark developments in the country, offering benefits such as reduced moisture movement, permanent surface protection, enhanced surface hardness, and rapid access to the slab following treatment. Its ease of application to freshly poured concrete further underscores its practical value in construction contexts.
“As the research continues, my objective remains consistent: to develop a deeper understanding of how these treatments influence both the performance and lifespan of concrete floors,” she states.
