Dingo Deep Void is a ready to use, high quality grout that expands in two stages (Class A and C) to counteract the shrinkage that is normally associated with Portland cement grouts. Dingo Deep Void Grout is a blend of Portland cement and selectively graded materials that result in a dense homogeneous mix enabling it to achieve high strengths in short times, making Dingo Deep Void suitable for grouting of large sections and deep pours of up to 500mm.
