Buildings & Structures (BSTR)



Roof Problem Areas (RPA)


Customer Location:

Private Airport Services, North Alabama U.S.A.


Application Date:

October, 2007


Application Situation:

The hanger houses NASAs corporate jet.  The internals of the hanger are spotless and the leaks presented an embarrassment for the owner.  Also in consideration was a banquet to be held inside the hanger within 10 days of our repair.



The roof of the hanger has 16 skylights and each one leaked. Several earlier attempts to seal skylights proved futile.



Belzona® 3111 (Flexible Membrane)




Application Method:

Applied utilizing Belzona Know-How System Leaflet RPA-3. Skylights were pressure washed clean, taped off areas around skylights to include joints and seams, applied Belzona® 3921 and 2 coats of Belzona® 3111 Flexible Membrane with Belzona® 9311 Reinforcing Sheet.


Belzona Facts:

After several prior attempts to seal leaks with other companies, airport personnel called us to fix the leaks.
