BIRSS 67 Shpurovaya — non-shrink injection compound for anchors and cracks
Flowable cementitious compound for crack injection, anchor fixing, grouting of bearings and soil stabilisation; water retention at least 98 %.

Akvapol is a two-component pigmented epoxy system that is thinned with water and contains no solvents. It can be used as a primer, as a roller-applied paint coat or as a self-levelling floor with quartz sand; a chip broadcast and Overlak sealer can be applied on top. The compound is more vapour-permeable than standard epoxies, can be laid on gypsum, magnesia and old epoxy substrates and suits dairies, meat-processing plants, bakeries, warehouses and filling stations; the colour is matched to RAL.
