The Stumbelbloc advantage
Faster
Blocks interlock and slot into place — no mortar beds, no endless levelling.
A 3m x 4m room can be built to roof height in a single day with just four people.
Stronger
Over double the strength required by the Standards Association of Zimbabwe.
The BlockGrip mortar bonds 15 times stronger than standard mortar.
Cheaper
One bag of cement lays 500 blocks, cutting cement and labour bills by up to 75%.
500 blocks can be laid in one day by a single bricklayer and one assistant.
Easier
Uniform, interlocking blocks that anyone can lay with only limited training.
Each block is exactly 400 x 200 x 200 mm and interlocks precisely, in line or at right angles.
The bond
BlockGrip adhesive
BlockGrip is a white polymer powder supplied in 1 kg tubs. Mix 1 kg BlockGrip with one bag of cement and one wheelbarrow of sand to form a “sloppy” mix. Dip each block about 3 cm into the mix before laying it on the wall.
