Product Information


  • Cementseal is used to prevent water ingress into basements, cellars and other below ground structures.
  • The product is suitable for use on exposed or inverted roofing and for podium waterproofing.
  • It can also used for temporary waterproofing in new construction, to protect from water ingress in order to allow finishing trades to access areas underneath in fast track construction.
  • The product when mixed exhibits a good degree of thixotropy to enable ease of application by brush or spray techniques to give an even finish with no sagging even in vertical situations.
  • It hydrates to form a durable, highly alkaline, tough and durable coating which not only protects the concrete, or other substrates, from water penetration and carbon dioxide diffusion.
