Monumental success
Kemperol cold-applied waterproofing has many applications beyond it’s typical use on new-build and flat roof repairs, due to it’s exceptional durability and reliability.
One of these was the refurbishment of the Canadian national memorial at Vimy Ridge in France, designed by Walter Allward in the 1920’s and erected in memory of the Canadian Expeditionary Force soldiers killed during the first world war. It was recently rededicated by the Queen in a ceremony to mark the 90th anniversary of the battle following a major three-year restoration.
The monument had suffered extensive water damage due to the original absence of a waterproof membrane to separate the massive Seget limestone blocks from the reinforced concrete foundations on which it is based. During its repair, the precisely-fitted blocks had to be painstakingly dismantled and refitted as part of a process which allowed a permanent waterproofing membrane to be installed.
Kemperol waterproofing uses specially-formulated polyester and polyurethane resins to impregnate an exceptionally strong polyester fleece, forming a permanently elastic membrane that bonds directly to almost all substrates. It has many applications beyond roofs, and is ideal for waterproofing structures from monuments through to bridge decks.
