Temperature swings consistent with the change of season can also cause the concrete to expand or contract to cause cracking. Block foundation walls - Shrinkage cracks ...

Crack from N.A. propagates toward edges: called web shear cracks From diagonal tension: Concrete tensile strength is given as: v cr = V bd = 3 f ′ c ⇔ 5 f ′ c tests shown that the best estimate of cracking stress is v cr = V bd = 3.5 f ′ c Note: The most common type of shear crack occurs only under high shear; with thin webs.

The type of repairs needed is dictated by ground conditions and material. The foundation will need to be stabilized first. To do this, steel pins are required.

Spread it on, and important, not just the crack but a good 60 or 70mm each side of every crack as well. Work it into cracks and into the surface where you can. When it sets, the next day, water won't be able to penetrate and reach the crack without traveling through 70mm+ of concrete, which is the protection the steel should have had.

In fact, most cracks in a poured concrete foundation are a natural result of foundation settlement and shrinkage of the concrete during the curing process and can be easily fixed or simply left alone. But if the cracks are abnormally large or allowing seepage to enter the home, they are often a sign of a more serious structural problem.

Early thermal cracking occurs due to the excessive tensile strains in the concrete than its capacity, and tensile strains are developed due to the thermal contractions or with the variation of temperature within a section. The development of the thermal cracking of concrete could be extended up to two to three weeks.

Correction of foundation and structural problems can be very costly and occasionally foundation cracks will be a warning sign of other structural issues with a home. 98% of the homes in the United States have foundations …

A less than optimum concrete mix can exacerbate this shrinkage. Shrinkage cracks are especially common in poured concrete foundations for the simple reason that the volume of uncured concrete is greater.

crack surface increases, thus increasing the energy demand for crack propagation. There is controversy, however, on the effects of coarse aggregate content …

The problem is the crush and run - or "crusher run" as I've heard it called - is compact-able - and 57 stone - gravel - naturally is compacted when it's dumped/spread. so you have the chance of settlement under/of the concrete and or cracking of a slab with a compact-able sub-base - unless you are able to fully compact it in lifts - layer by layer.
