ACRtec L43 Crack Filler
ACRtec L43 Crack Filler is a two-component, surface applied, cementitious crystalline crack filling material for concrete and cement protection. When applied to concrete cracks that are no longer moving, the insoluble crystals within the product react with the waterproofing material to form and develop in the water bearing capillaries, effectively blocking the passage of water and ensuring permanent water tightness throughout the life of the structure.

Performance Properties
ACRtec L43 Crack Filler is made up of 2 components. Part A the cementitious powder and Part B the reactive liquid. When Part A and B are mixed and applied to a concrete or cement surface, the material reacts with the lime in the concrete to create a penetrating waterproofing crystalline barrier. The crystals that are formed when the material is placed in the crack penetrate the capillaries of the surrounding concrete and prevent moisture from passing. ACRtec L43 Crack Filler’s crystals will be fully developed and functional after 7-10 days. Once the crystals are fully developed, the chemicals that penetrated into the surrounding existing concrete help to strengthen and reinforce the surrounding concrete. This means that cracks only need to be dry and free of debris, no routing or grinding is necessary to use ACRtec L43 Crack Filler.
