Why Use Stumbelblocs?

 

 

Cheaper:

Using Stumbelblocs is cheaper because they use MUCH LESS CEMENT than standard blocks and DON'T REQUIRE MORTAR BETWEEN COURSES or between blocks. No electricity, petrol or diesel required in the manufacture, only local sand and cement. Stumbelblocs are usually about 75% cheaper to produce than purchasing standard blocks. Full blocks I've made in Maun, Botswana have cost approximately P4.00 each (plus labour).

 

Quicker:

Because they interlock and are therefore just slotted into place. No time is wasted laying down mortar for each course of blocks and endlessly levelling blocks.  Construction can be achieved in record time: eg. a 3m x 4m room can be built to roof height in 1 day (with 4 men)

 

 

 

Laying the Stumbelbloc

(note BlockGrip cement adhesive bonding blocks together)

 

Easier:

Laying each block in place takes seconds because they interlock. The only tools required for making blocks are a mould, a shovel (for mixing) and a builder's trowel (for finishing).

 

Stronger:

Because they are 'wet moulded', not 'dry moulded, like standard blocks. BlockGrip bonding agent is used to glue the blocks together when building larger structures.

 

Much more accurate:

Each block is exactly 400mm x 200mm x 176mm, and they interlock extremely precisely with the next block, either in line or at right angles.

 

Cooler:

Each full block has two large air-filled cavities which are natural thermal insulators, and also allow the warm air in the cavities to rise and exit the house.

 

Practical:

Electical cable and plumbing is not chased into walls, but is led through the cavities in the blocks. These cavities may also be filled with insulating foam or polystyrene granules for further insulation. No lintels required above doors/windows less than 1.5m wide.

 

No special skill required:

People with little or no education or skill can manufacture and lay the blocks. Only limited training is required.

 

On-site manufacturing:

Blocks are usually manufactured on-site, thus eliminating transport costs.

 

BlockGrip Adhesive:

BlockGrip is a white powder polymer which comes in 1Kg tubs. Mix 1kg BlockGrip with 1 bag cement and 1 wheelbarrow sand to form a 'sloppy' mix. Dip each block about 3cm into the mix before laying in place on wall. This will bond the blocks together extremely strongly (see photos in gallery). 1kg BlockGrip will bond approximately 600 blocks.
