Romex Trass Bed is a frost-resistant, permeable paver base made by mixing with ASTM #9 stone and water. Once leveled, a thin-set is applied to the back of each paver for a wet-on-wet bond that prevents movement. Replacing both the mortar and slab bed, it speeds up installation and reduces embodied carbon by about 30%, making it a sustainable alternative to concrete.
