Aggregate Industries has partnered with BASF Construction Chemicals to launch its leading Watertight™ concrete, a new range of specialised concretes designed to protect a structure from water ingress or to retain water within a structure.

Watertight offers contractors and specifiers a fast solution that prevents water from flowing into or from a structure.

It is fully compliant with BS 8102:2009 Code of practice for protection of below ground structures against water from the ground Type B construction and is available as a pumpable or flowing mix in slump and flow grades.

Designed by Aggregate Industries, the Watertight range has a full scope of admixture-driven solutions and is available as a three-tiered waterproofing solution, Watertight Pro Protect, Watertight Super Protect and Watertight Core Protect.

Customers can choose the right solution depending on application and level of waterproofing required.

Each tier is specially formulated using Watertight concrete mixed with a custom blend of BASF’s MasterLife WP 799, a waterproofing system for concrete incorporating combined waterproofing and superplasticising components.

Aggregate Industries is also the first construction materials supplier to offer an Environmental Product Declaration (EPD) on its Watertight concrete, providing clients with detailed information on its environmental impact.

The tool enables Aggregate Industries and BASF to quantify the environmental impact of specialist and conventional concrete mix designs based on factors such as global warming potential or o-zone depletion potential.

Joanne Wilkins, Head of Business Development - Asphalt and Ready-Mixed Concrete at Aggregate Industries, said: “At Aggregate Industries, we understand that waterproofing isn’t a one-size-fits-all approach.”

“That’s why we’ve partnered with BASF to develop our Watertight range into a new three-tiered system – giving architects and specifiers greater flexibility than ever before when choosing an appropriate waterproofing solution.

BASF provides RIBA-approved CPD seminars to architects, contractors and specifiers to help them understand the different types of waterproofing products available, their key characteristics and where they should be specified for maximum performance and durability.
