Cracking Concrete Basement Wall
Cracking Concrete Basement Wall
(OP)
My brother has a 8" & 10" basement walls poured with #4 at 12" o.c. both horizontally and vertically. It is a rectangular basement, 28'x45'. The walls are 9' to joist bearing from basement slab. The 8" wall is the 45' wall and has developed a vertical crack @ 20' from the side wall on both the front and back walls. It is visible on the interior and exterior or the house. No wall deflection or settlement difference is noticed at the cracks. i am assuming it is a shrinkage crack, but was wanting to seek others opinions on this matter. The house was premanufactured and set 4 days after the basement was poured. ANy thoughts would be appreciated.

Is the soil clay? Is the property poorly graded? This could add stress to an 8" 45' long wall...and raise concern.

I would clean the surface, epoxy the cracks and replace the upper 4 feet of backfill soils(only along the 40' sides)with pea gravel and 1 foot of soil cap. Just make sure that the drains at the bottom are working.
