Crackbond LR321 is formulated for use as an injection resin for cracks in structural concrete, masonry & wood. It’s also perfect for epoxy grouting, healing-sealing or as a mortar when mixed with sand. It has the viscosity of light oil and low surface tension, allowing it to deeply penetrate fine cracks. It cures to a solid with no shrinkage, bonds to both surfaces of the crack, bonding the structure back to its original monolithic strength.
