U-boot is basically recycled polypropylene materials that can be used as a framework to design and create lighter slabs and rafts foundation in RCC structures. The use of U-boot components permit the construction of specific mushroom slabs; the mushroom forms a part of the final slab thickness. The U-boot component remains dipped into the concrete casting. Thus, a grid of orthogonal beam, superiorly and inferiorly closed by plane slab of different heights, is obtained without executing two distinct concrete casting, and this implies saving of concrete and reinforcement.

Keywords: Saving concrete and reinforcement, good stability to slab member.
