Watertight concrete
1 of 1 | Watertight concrete


Watertight is a versatile range of specialised ready mix concretes designed to protect a structure from water ingress or to retain water within a structure.  When compared to traditional methods of achieving watertight structures, Watertight® offers contractors and specifiers the competitive edge in both cost and time savings.

Watertight provides a fast track solution over traditional methods of construction such as external membranes or cavity drainage. With Watertight, water is prevented from flowing into or from a structure and eliminates the need for the time consuming installation of complicated and detailed jointing.

The Watertight range encompasses the full scope of admixture driven solutions and upon request can be supplied with a manufacturers warranty giving you the confidence to specify and use a unique product.

Key benefits

When correctly specified and constructed Watertight:

  • Is fully compliant with BS 8102 type B construction
  • Reduces installation time
  • Is not sensitive to weather conditions unlike membrane solutions
  • Available as a pumpable or flowing mix in slump and flow grades.
  • Reduces installation cost


Watertight finds applications wherever a significant hydraulic gradient is found.

Watertight is available in concrete grades suitable for applications ranging from service reservoirs, water treatment structures, car parks, domestic basements and swimming pools. We will tailor Watertight Concrete to the particular challenges of your contract and provide detailed advice and support during the initial use of the product.
