Mastic Asphalt is without question the toughest and most durable waterproof membrane available to architects, building owners and other key specifiers. 

Its use is most commonly associated with flat roofing applications due to its waterproofing properties but is also a perfect choice for a whole range of construction applications, which is why it is commonly applied to entrance steps, balconies, parapet gutters, basements and carparks where a seamless, durable surface is required.

Where failure does occur, our team at THL Maintenance can inspect your roof, identify the underlying cause of the failure and provide approved specialist repairs to restore the asphalt and ensure its continuing performance.
