Heidelberg Materials Watertight concrete

A simpler alternative

Discover a simpler solution for achieving watertight structures with Heidelberg Materials' watertight concrete, available in Bronze, Silver, and Gold variants, each offering up to 25 years of guarantee protection.

Designed to save contractors, engineers, and clients both time and money, our watertight concrete incorporates advanced admixture technology from our trusted partner, Sika. This ensures superior performance and peace of mind for every project stakeholder.

Unlike traditional ready-mixed concrete, which can allow water to pass through capillary pores (due to the water/cement ratio), our watertight concrete minimizes this risk, providing enhanced protection and reliability for your construction needs.

Our two-step process ensures watertight concrete:

1. Reduce the water/cement ratio - This increases mix density, minimises pore size, and produces highly workable concrete for easy placement and compaction.
2. Block remaining capillary pores - This ensures a completely watertight finish.

For a reliable and efficient solution to watertight structures, choose Heidelberg Materials' watertight concrete with upto 25 years warranty.
