Gaza Project Turns Rubble Into Interlocking Bricks for Shelters

Inside a makeshift workshop in Gaza, Suleiman Abu Hassanin oversees the conversion of broken concrete into interlocking construction blocks. The effort began after conventional building materials became unavailable following nearly two years of intensified bombardment.

Gaza’s construction crisis predates the latest conflict. For years the Israeli blockade limited imports of cement, steel, and other supplies, slowing earlier rebuilding. UN estimates now place the volume of rubble at more than 60 million tons, while hundreds of thousands of displaced residents remain in tents.

Workers crush and sort debris, then combine it with local soil and alternative binders developed inside Gaza. The mixture is compressed in a hand-built machine into Lego-style blocks that require no traditional mortar. Engineer Wajdi Jouda helped set the brick dimensions to meet basic engineering standards.

Early tests indicate the blocks offer improved thermal and sound insulation compared with tents. Current output of 1,000 to 1,500 bricks per day could theoretically produce a small shelter in roughly two weeks. The project reduces material costs by an estimated 50 to 60 percent and provides work for displaced residents.

Humanitarian organizations have warned that Gaza rubble may contain asbestos, heavy metals, and unexploded ordnance. The bricks remain experimental and have not been tested at neighborhood scale. Funding shortages and the continued blockade of conventional materials continue to constrain expansion.

Abu Hassanin described the effort as a direct response to the absence of imported supplies. He noted that participants move from receiving aid to actively rebuilding their own surroundings.
