What Is Mastic Asphalt?

Mastic Asphalt has been used as a waterproofing compound since antiquity, with its origins dating back to the Phoenicians. Boasting unrivalled water-resistance and longevity, it is no wonder that Mr Claridge patented the compound in Paris in 1837, hence the name Claridge’s Patent Asphalt. This high-quality protection can be found on some of the U.K.’s most iconic landmarks, such as St Paul’s Cathedral and Buckingham Palace.

This mixture of limestone, bitumen and modern polymers is renowned for its durability. It can withstand both foot and vehicle traffic and is non-toxic and non-flammable.

Are Asphalt and Bitumen the same?
