Heidelberg Materials Watertight concrete
A simpler alternative
Heidelberg Materials range of waterproof concrete is a simpler alternative offering contractors, engineers and clients the competitive edge in both cost and time savings compared to traditional methods of achieving watertight structures. Heidelberg Materials' Watertight Concrete is available from all of our static and mobile production plants.
Utilising the latest admixture technology from admixture partner Sika®, Heidelberg Materials' waterproof concrete gives confidence to all those involved in the project.
Every good quality concrete will allow the passage of water through it as a function of capillarity, when there is water on one side of the structure and air on the other, the volume of capillary pores in the concrete mix is proportional to the water/cement ratio.
A two-step process is used to achieve a waterproof concrete:
Step 1: Reduce the water cement ratio, increasing the density of the mix and minimising the size of the pores whilst producing a highly workable concrete to aid placement and compaction.
Step 2: Block the remaining capillary pores ensuring a complete watertight finish.
