As the winter approaches, 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.

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.

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 excellent adhesion to most construction 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.
