One of the advantages of Rubb Buildings is our ability to provide fast and cost effective foundation solutions.
Rubb BulkBlocks™ serve as one of our most accommodating foundation options yet. Built with high strength steel that is reinforced in pre-cast concrete, Rubb BulkBlocks™ are engineered to meet building codes that other foundations may not.
Rubb BulkBlocks™ can remain permanent or be relocated in the case of a temporary structure. They serve as both a foundation and a retaining wall, a convenient and economical design that is ideal for all bulk storage needs including sand, salt, and agricultural storage facilities.
Rubb BulkBlocks™ can also be locally produced, providing a less expensive solution to traditional poured foundation.
