  • Standard and Lightweight Block | Brampton Brick

    Standard concrete units are primarily used for exterior loadbearing and foundation walls. Lightweight Concrete Block units are used for interior use, particularly because of its higher fire rating and sound absorbing properties. These concrete blocks come in four sizes and six styles, including Ashlar, Frog, Return Corner and Single Bullnose.

  • Concrete Block Vs. Brick | Hunker

    Brick and block are both relatively strong materials, but their strength in a wall is affected by the type and quality of mortar holding them together. According to the Masonry Advisory Council, all concrete blocks must have a minimum compressive strength of 1900 pounds per square inch. Many dense blocks are stronger than this.
