Concrete blocks VS Clay bricks Concrete blocks will shrink over time while clay bricks will expand.
Bricks : •Is a standard masonry unit which is made out of clay •Is permeable (non-water proof) •Advantage: Bricks can be joined with water based mortar. If adequately ventilated so that any wetness can escape, they will not deteriorate. •Disadvantage: Bricks absorb moisture and expand overtime—expansion joints required Salts and lime from the soil can be drawn up through the bricks when in contact with ground. This may cause serious pathologies and aesthetic problems such as efflorescence.
