Kenya’s Construction Crisis: Engineers Sound Alarm Over Substandard Cement Flooding Market

Safety concerns mount as cement quality drops 25%, putting lives and property at risk

NAIROBI – Kenya’s construction industry faces a mounting crisis as engineers raise urgent concerns about substandard cement flooding the market, with some products showing up to 25% reduction in strength and weighing significantly less than advertised.

The Institute of Engineers of Kenya (IEK) has documented alarming quality deterioration across multiple cement brands, including those bearing the Kenya Bureau of Standards (KEBS) quality mark, raising serious questions about regulatory oversight in the country’s booming construction sector.

IEK President Shammah Kiteme revealed that engineers have recorded substantial drops in compressive strength across various cement brands, compromising the structural integrity of buildings and infrastructure projects nationwide.

“This is a grave threat to public safety,” Kiteme emphasized. “The built environment must meet certain performance thresholds to withstand both everyday use and natural shocks. When cement is compromised, then life and property are directly at risk from compromised structural integrity.”

The quality issues extend beyond strength concerns. Hardware stores and retail outlets are selling cement bags marked as 50kg that weigh significantly less—some as low as 45kg—representing a fraudulent practice that violates consumer rights while potentially compromising construction projects.

The discovery of substandard products bearing KEBS quality marks has intensified scrutiny of Kenya’s regulatory framework. The situation suggests either inadequate testing procedures or potential corruption within the certification process.

Consumer Federation of Kenya (Cofek) has previously linked building collapses in Nairobi and Kiambu counties to substandard construction materials, including cement. Their independent testing revealed that nearly all brands tested were underweight and failed to meet the recommended 32.5 unit strength standard.

“In some cases, the problem starts and ends with deceptive labeling – to take advantage of majority consumers who focus on the price – and not quality,” Cofek noted in earlier statements.

IEK is demanding comprehensive reforms to address the crisis, including:

– Immediate market audit : A complete review of all cement manufacturers and brands operating in Kenya.

– Enhanced surveillance : Random sampling from hardware stores and distribution points to verify quality and conformity.

– Mandatory weight verification : Enforcement of weight checks before cement dispatch, with penalties for non-compliance.

– Criminal investigations : Prosecution of individuals, including public officials and private sector players, complicit in compromising construction material standards.

The cement quality crisis poses significant risks to Kenya’s construction boom, which has been a key driver of economic growth. Substandard cement not only threatens immediate safety but could lead to premature structural failures, costly repairs, and potential loss of life.

For consumers, the underweight cement represents direct financial fraud, while the reduced strength could necessitate expensive retrofitting or reconstruction of affected structures.

Kiteme emphasized that addressing the crisis requires coordinated action across multiple stakeholders: “We require the collaboration of regulators, law enforcement agencies, manufacturers, and professional bodies to uphold standards, ensure compliance, and protect the lives of Kenyan citizens.”

The IEK has committed to continued monitoring of the situation and regular updates on progress or lack thereof. The organization stands ready to collaborate with stakeholders to restore integrity, safety, and professionalism to Kenya’s construction industry.

As Kenya continues its rapid urbanization and infrastructure development, ensuring the quality of basic construction materials like cement becomes not just a technical issue, but a matter of national safety and economic security.

The current crisis demands immediate, decisive action to prevent potential catastrophic consequences for the country’s built environment.
