Grillage foundations are constructed using a framework of beams, typically made from concrete or steel, which supports a structure by distributing loads across a large area. This distribution helps manage vertical loads effectively.

The characteristic that grillage foundations do not typically possess is low weight. In fact, one of the distinctive features of grillage foundations is their substantial weight, as they are designed to provide stability and load resistance. Their construction methods often lead to a heavier foundational system compared to other lighter options.

On the other hand, grillage foundations are known for their cost-effectiveness as they utilize available materials and can often be constructed with fewer resources compared to deeper foundations. They are also praised for their ease of construction, as the grid-like structure can be simpler to assemble on-site. High load distribution is indeed a key advantage of grillage foundations, allowing them to support much heavier structures due to their design, which spreads out the weight over a broader area.
