Concrete Shrinkage + Restraints = Tensile Stresses = Wall Cracks Another way of thinking about this shrinkage and restraint behavior is to place our 100 ft. wall in outer space.

Retaining walls cost between $1,000 and $10,000 for a typical 4-foot by 25-foot wall or around $5,500 on average. The overall costs depend on the dimensions of your particular wall, the wall style ...

The original block layers may not have the wall perfectly plumb or in the same plane, and one giant U-shaped form may be very hard to align if it’s one piece about 7 feet tall.

Durability. A concrete wall can stand up to the test of time, often lasting for a century or longer. Resistance. Do you want a retaining wall that’s fireproof, rot-proof, and rustproof?
