The term “Concrete Cancer” is a slang term for any one of a number of defects in concrete, describing a destructive process that eats away at the concrete, and the condition slowly getting worse if it remains untreated.. Concrete Cancer is caused by many factors: Including: carbonation, moisture, efflorescence and salt. When concrete cracks, water penetrates through causing the steel reinforcement deep inside to rust. Rusting steel then sheds its skin forcing the layers of rust to push away the concrete surrounding it.

Before we can repair concrete, we have to find out what caused the problem, and come up with the best concrete repair solution.

We do the necessary preparation, remove any unsound concrete and contamination, then install a repair designed to solve the problem.

Methods: control joint inserts, masonry caulks, radon crack sealants, semi rigid epoxy resin crack fillers, special poly urea caulks designed as a joint filler – polyurethane foam injection to seal cracks, grouts including portland cement, latex-modified, epoxy, modified epoxy-supported, and furan grouts or other products used to fill or seal cracks in concrete or other masonry surfaces & structures.

Crazing is the development of fine random cracks or fissures on the surface of concrete, caused by shrinkage of the surface layer. Overworking the concrete surface during finishing can bring too much of the cement paste to surface, and result in a weak surface. Most cracks are cosmetic, but still there are the potential for deleterious structural effects, if not repaired.

Concrete is strong in compression, but weak in tension and a crack implies that the concrete was in tension. The crack is ALWAYS perpendicular to the direction of the tension!
A typical shrinkage crack running diagonally from a re-entrant corner in a concrete slab. The concrete was shrinking back in each direction from the corner and that diagonal crack is perpendicular to the direction of shrinkage.
