The present example provides a building foundation repair product that is a horizontally cast concrete product. Horizontal casting, unlike the typical vertical casting produces smooth end surfaces that aid in installing the building foundation repair product as the end surfaces are defined by the mold. Also, the building foundation repair product has been designed with flat surfaces that make up its sides. The flat surfaces advantageously tend to prevent the product from rolling when used at a job site, and allows the a building foundation repair product to be easily palletized for shipping, as they tend to be stable when stacked on the pallet.
