Because the base is the widest part (10 units), your foundation must accommodate this footprint. Mark your starting point. For a curved wall using 10 to 7 mod top blocks, place the first block with the 7-inch side facing the direction of the curve.
As we move into the era of BIM (Building Information Modeling) and CNC manufacturing, the humble 10 to 7 mod top is getting a digital upgrade. Manufacturers are now embedding RFID chips into these modules. 10 to 7 mod top
Why? Because a 10-to-7 taper is difficult to identify once several courses are stacked. With digital tagging, a scanner tells you exactly which block is a 10-to-7 mod top versus a standard straight block, even under dirt and vegetation. Guide: The 10-to-7 Mod Top (Modification for Upper
Furthermore, 3D-printed concrete is allowing for "variable mod tops" – blocks that transition from 10 to 7 on one edge, but 10 to 6.5 on the other edge, creating double-curved surfaces (hyperbolic paraboloids). The Sleeve: As described, ending precisely at the
In landscaping and heavy civil construction, "mod top" blocks are famous for building curves. A standard straight block has the same top and bottom width (e.g., 10 to 10). However, a 10 to 7 mod top block is used exclusively for concave curves (curving inward relative to the wall face).
