Due to its capillaries and pores, concrete is a naturally-porous material. The Sika® Watertight Concrete System incorporates a range of admixtures to improve its resistance to infiltration.
- Sika® WT-200 P – a combined crystalline waterproofing concrete and HRWR/Superplasticiser admixture.
- SikaControl® -501 WT - a combined water resisting, crystalline waterproofing admixture that is compliant with regulation 31 for drinking water applications.
- Sika® 1 – a liquid water-resisting waterproofing admixture.
