Ballasted Roofs
by Sika-Trocal
A ballasted (gravel/paved) roof will generally require a stronger supporting structure than that for the exposed membrane one, but will allow the roof to be used as a trafficked or leisure use area. Additionally a ballasted roof will provide a higher degree of sound reduction and, if covered with minimum 50 mm depth of gravel ballast or 50 mm thick pavers, is deemed to achieve an FAA fire rating.
