Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).

Adds a lot of weight to the roof system, typically 10-15 pounds per square feet. Extremely difficult to find a leak in this system, since the membrane is well hidden. Ballast stone traps a lot of dirt, making patching difficult. Ballast stone fractures and gets sharper over time, which can puncture the membrane.

Overview. This trade pack provides sand and stone ballast that creates concrete when added to cement. Ideal for concreting and laying screeds, it can also be used to provide an even and strong sub-base prior to laying paving for projects such as driveways and shed bases. Supplied in plastic packaging and suitable for outside storage.

Since the ballast is the primary resistance to wind uplift, there has to be a lot of ballast installed on the roof. Most systems have 10 to 12 psf for ballast. If you do the wind uplift calcs, that's woefully deficient for higher wind load areas so if that's where you are, recommend against its use.

Ballast less than 300 mm (12 inches) thick can lead to vibrations that damage nearby structures. However, increasing the depth beyond 300 mm (12 inches) confers no extra benefit in reducing vibration. In turn, track ballast typically rests on a layer of small crushed stones: the sub-ballast.
