Uganda: Hydrautec Blocks, a Solution to Easy Construction

For 79 year old Siperanta Nakubulwa, hopes of ever living in a decent house were dim. But this hope was rekindled, thanks to a new technology, Hydrautec.

After good Samaritans came to her rescue, she was able to own a two bedroomed house in her remote village in Buzirandulu Village in Nakifuma, Mukono district. The house that was commissioned by President Museveni has been adopted as a model house for the elderly in Mukono district and across the country.

Vincent Kamoga a civil engineer with Masters in Engineering says the new technology that is being used world over can be instrumental in addressing the low inadequate housing in the country.

"All that one needs as material with the new Hydrautec technology is natural soil but not top soil which is suited for agriculture. Anybody with a piece of land or plot can actually construct a house in just a week's time," said Kamoga.

He explains that the stabilizing of the soil for the block making depends on strength of blocks required. "Kamoga stresses that for one to get the best, it is important to use Pozzolanic cement. The mixing should be 5-8% by weight. 5 percent being for normal construction while 8 percent for load bearing wall (storied building)," he said.

Kamoga says unlike the ordinary baked clay bricks that have between 1.5 to 2 MPA, Hydrautec (ISSB) blocks are 4- 7 MPA, the soil stabilised blocks have been tested by Uganda Government and passed as a standard building material.

"Ballistic tests on the ISSB attests to the fact that Hydrautec blocks are resistant to all caliber bullets," he said.

Kamoga said Ugandans can use the new SVO7 MC Hydrautec machines from Turkey to make their house construction easy. He says the 17 Horse-power, dual-chamber, self-starter machines can churn out 4,000 blocks a day.

"The machine makes a block in every 15 seconds. In one minute it makes four highly compressed blocks that is ready for use after five days of curing," he told New Vision.

The machine uses between 12-15 liters of diesel to make 4,000 blocks in eight hours.

"You need 12,000 blocks to construct an average medium three bedroomed house or 8000 blocks for a 50 by 100 perimeter wall. He said

He explains that the comparative advantage of these blocks is that it cuts construction costs by 60 percent yet it is also environmentally friendly.

"Unlike the ordinary bricks that are cumbersome to make and causes adverse effects to forests and swamps, Hydrautec blocks are environmental friendly," he said.

The machines are traffic complaint. They can be transported anywhere on its tyres.
