With winter almost upon us, the anticipated damp and sub-zero temperatures will provide a severe test of the quality of the concrete used to build structures old and new. Over time, frost and ice will do its best to debilitate a building by finding its way into cracks caused by any one of a number of issues. Excess water in the concrete mix; improper strength of concrete poured on-site; conditions too cold for effective application…these are just some of the reasons fissures, which are susceptible to the freeze/thaw process, resulting in crack-widening and the structural integrity of the concrete being tested. Spalling is another common issue that can compromise concrete surfaces.
Fortunately, Sika has a proven, high-performance solution for crack repair in newly-poured and refurbished concrete. Sikadur®-52, an injection or poured epoxy resin, provides a reliable seal for a wide range of structural or non-structural applications and uses such as joint and hole filling; crack and void sealing. Easy to mix and apply, Sikadur®-52 is ideal for dry and damp concrete surfaces in horizontal and vertical locations. Proper bonding between the resin and substrate is essential for a durable repair. Sikadur®-52 is recognized for its best in class performance and class-leading durability.
Crack repair using Sikadur®-52 couldn’t be simpler. The crack itself doesn’t need to be cut out or the area widened before filling. Sikadur®-52, with its low viscosity, permeates into the smallest of cracks to provide a permanent seal. Impermeable to liquids and water vapour, the system hardens without shrinkage – a vital property when repairing cracks. As well as offering superb abrasion resistance and mechanical strength, Sikadur®-52 provides concrete excellent adhesion to most materials including natural stone, ceramics, fibre cement, mortar, bricks, masonry steel, iron and wood. It is the ideal concrete crack-repair solution for a wide range of infrastructure projects. Slabs, beams and columns found in buildings, bridges and the like are among surfaces ideal for the application of Sikadur®-52. The upkeep of our infrastructure is not only vital to maintaining elements such as nationwide road and rail routes; neglecting to treat cracks in concrete structures sooner rather than later can lead to greater damage and costly, time-consuming repairs.
Note: Always follow the manufacturer’s safety guidelines. This could result in cash-strapped local authorities passing the financial burden of such work onto the community in the form of increased council tax bills. Prevention is better than cure, as the well-known saying goes, and so it is better to repair concrete when the damage is minimal with a reliable, robust solution such as Sikadur®-52, before greater problems take ahold. To ensure areas that have been repaired are protected from future environment conditions, such as freeze thaw, concrete facades, column, soffits etc. are coated with anti-carbonation coatings. Sika offers a range of coating solutions, which include water based crack bridging systems, resin coatings and hydrophobic impregnations. In buildings and infrastructure projects these protective systems are applied as part of the future repair and maintenance strategy.
When using Sikadur®-52, the approx curing time may vary depending on temperature and should be checked before use. Proper fixing of cracks is essential for long-term durability. Sikadur®-52 is hardening styrene free resistant to water, chemicals, and solvents, and has been solvents tested for durability in harsh environments. User review feedback highlights both the ease of use and the product’s strong adhesion. The importance of proper packaging ensures product quality and facilitates application.
