Crystalline waterproofing admixture
Batimix HCA 100 is an integral crystalline admixture powder specifically formulated to interact with concrete capillary pore structures to provide a waterproofing system that is a permanent part of the concrete matrix.
Batimix HCA 100 can be used in above and below-grade applications. Active chemicals combine with the free lime and moisture present in the capillary tracts and pores, to form insoluble crystalline complexes. These crystals block the capillaries and minor shrinkage cracks in the concrete to prevent any further water ingress (even under pressure). However, the concrete will still allow the passage of water vapor through the structure (i.e. the concrete will still be able to "breathe").
Batimix HCA 100 has the following characteristics:
Batimix HCA 100 contains products that are irritating to the eyes and skin. In case of contact, rinse immediately with plenty of water. Wear suitable gloves. For further information, kindly refer to the product's Material Safety Data Sheet.
Batimix HCA 100 can be used in drum mixed and central batched concrete applications. It should be added to the initial batching sequence preferably as the aggregate is being added to the mixing vessel. Concrete should be mixed a minimum of 8–10 minutes, at normal mixing speed, after all concrete constituents have been batched to ensure thorough dispersion of all materials. Batimix HCA 100 should not be added to the concrete mixture after the cementitious ingredients have been introduced.
General Remarks:
Batimix HCA 100 should be stored in a closed and dry place. Avoid freezing and excessive temperatures. Unopened bags have a shelf life of six months when stored as recommended.
