Aggregate Industries and BASF launch waterproof concrete

Aggregate Industries has partnered with BASF Construction Chemicals to launch WatertightTM concrete. This is a new, versatile range of specialised 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, the concrete is a fast-track solution that prevents water flowing into or out of a structure. When correctly specified and constructed, Watertight is fully compliant with the BS 8102:2009 Code of practice for protection of below ground Type B construction. It also reduces installation time, is not sensitive to weather conditions, and is available as a pumpable or flowing mix in slump and flow grades.

Designed by Aggregate Industries, the Watertight range encompasses 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.

With a range of specialist products, offering a one-stop-shop solution that includes Type A, it is possible to choose the right solution depending on the application and the level of waterproofing required. On request, this solution can also be supplied with a manufacturer’s warranty, giving the customer confidence in specifying and using a unique product.

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

Reflecting the company’s commitment to sustainability, 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 EPD, published by the Institut Bauen und Umwelt (IBU), is based on life-cycle assessment (LCA) calculations using BASF’s Life Cycle Analyzer tool, which has been developed and third-party verified, in accordance with BS EN 15804:2012 Sustainability of construction works – Environmental product declarations – Core rules for the product category of construction products.

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, ozone depletion potential, and acidification potential, and generates a full LCA of concrete (cradle-to-grave) or an assessment of the production stage only (cradle-to-grate).

“At Aggregate Industries, we understand that waterproofing is not a one-size-fits-all approach,” said Joanne Wilkins, Head of Business Development. “That is why we have 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.

“What is more, given the ever-rising importance of sustainability, we are the first construction materials supplier to offer EPD to determine the environmental impact of our Watertight concrete. This will make it easier for our clients to meet the environmental requirements of a project by providing detailed information on everything from production to recycling options.”

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.
