Kistal 9A
KISTAL 9A is a chloride free, unique chemical admixture supplied in the form of grey powder. It is added to concrete and mortars during batching, hence reducing time and labour than other waterproofing methods. Its unique crystallization properties impart both self-healing and waterproofing properties for any concrete throughout its lifetime. KISTAL 9A distinguishes itself from usual powdered form waterproofing admixtures with a low water absorption rate – tested against BS 1881: Part 122 with absorption below 0.25.
