How to Build on Decomposing Granite

From driveways to patios, laid stones require a sturdy surface as a base. Decomposing granite provides this, as it can be tamped and settled to remain flat and unmoving for many years. Any project that requires stones or bricks to be laid on the ground may be built on decomposing granite. Mix the granite with a stabilizer if desired or use it in its pure form.
