Ground Face Concrete Block

Our ground face block reveals the true beauty of concrete masonry by grinding and polishing the face of the block to expose the aggregate beneath. We have a state of the art grinding machine that polishes the blocks flawlessly. After installation the blocks should be washed with a cleaner and sealed with a ground face sealer to bring out the true colour and aggregate. Choose the ground face finish on your next project where concrete masonry is exposed. The ground face finish dresses up an otherwise ordinary looking space into something unique.

Ground face is available in any shape or size.

The blocks must be ground from a special dry block mix and need to cure for a minimum of two weeks before grinding. With that in mind allow a month lead time for all ground face orders.

Tristar produces a semi light product that uses a percentage of pumice in its mix design instead of the standard aggregates. These blocks are up to 3 kg lighter for the 20cm unit. Semi Light blocks are more expensive but the savings will be revealed on site when the masons lay more units per day with less fatigue. Semi light blocks are not normally stocked except for the 21cm standard unit (8′ imperial). Although any block can be produced in semi light please allow time for production scheduling. The semi light also has a unique look when used in a split-face or ground face application. The pumice used in the mix is exposed and adds more diversity to the aggregate in the form of white specks throughout the block. This is especially noticeable in colour blocks.

Tristar’s has a ULC certified block for fire rating. These blocks exceed the standards and have no problem meeting the 2 hour fire rating. Every year Tristar sends out their blocks to get a full manufacturing review by a CSA approved company. The test results are available upon request. Call or email the office for this information.
