Conbextra BB is a ready to use cementitious grout supplied in 25 kg moisture resistant bags. It has been formulated specifically for grouting of bridge bearings and parapet post baseplates. Conbextra BB can be used in section thicknesses of 10 mm to 100 mm. The dry powder is a blend of Portland cements, graded silica sands and additives to which only a controlled amount of clean water is added in situ to produce a highly flowable, non shrink grout.
