Strategic Actions for Construction Stakeholders Amid Kenya’s Cement Quality Decline
The decline in cement quality in Kenya has become a pressing concern for every player in the construction ecosystem. The Institution of Engineers of Kenya (IEK) has raised the alarm, citing a surge in substandard cement and its direct threat to public safety, property, and the credibility of the nation’s built environment. If you’re a student, academic, or professional in the construction industry, this deep dive will equip you with actionable insights, practical frameworks, and the latest data.
What Is Driving the Cement Quality Crisis in Kenya?
Defining Substandard Cement
Substandard cement refers to cement products that fail to meet the minimum performance, weight, or chemical composition standards as set by regulatory bodies such as the Kenya Bureau of Standards (KEBS). This can include:
Reduced compressive strength
Incorrect chemical composition
Underweight packaging (e.g., 45kg instead of the standard 50kg)
Poor setting times and durability
Key Entities Involved
| Entity | Role/Responsibility |
|---|---|
| Institution of Engineers of Kenya (IEK) | Advocacy, technical audits, public safety alerts |
| Kenya Bureau of Standards (KEBS) | Regulation, market surveillance, certification |
| National Construction Authority (NCA) | Oversight, compliance, enforcement |
| Cement Manufacturers | Production, quality control, supply |
| Contractors/Developers | Material selection, site supervision |

Recent Trends and Data: How Bad Is the Situation?
Market Surveillance and Test Results
According to Cemnet, a 2022 KEBS report revealed that only 38.1% of cement samples met the required standards, while a follow-up in December 2023 showed improvement to 63.4% compliance after regulatory crackdowns. In 2025 at the time of writing this article, IEK documented up to a 25% reduction in compressive strength in some brands, even those carrying the KEBS mark.
| Year | % of Cement Passing Standards | Key Findings |
|---|---|---|
| Feb 2022 | 38.1% | Majority failed compressive strength, chemical tests |
| Dec 2023 | 63.4% | Improvement after stricter surveillance |
Economic and Social Impact
Building Collapses: Between 2009 and 2019, 86 buildings collapsed due to substandard materials, costing over KSh 2.4 billion.
Price Pressures: Cement prices surged 15-30% since 2022, with a 50kg bag now costing KSh 720–1,250, driven by higher input costs and taxes.
Public Trust: Frequent failures erode confidence in the construction sector and threaten investor interest.

Strategic Actions for Stakeholders
What Has the Institution of Engineers of Kenya Recommended?
IEK has outlined a series of urgent interventions to address the crisis:
Thorough Audits: Independent audits of all manufacturers
Random Sampling: Product checks at hardware stores and distribution centers
Mandatory Weight Verification: Enforce strict weight checks before dispatch
Prosecution: Legal action against those found culpable
Collaboration: Joint efforts among regulators, law enforcement, manufacturers, and professional bodies
Stakeholder-Specific Actions
For Manufacturers
Invest in advanced quality control technologies
Adopt Total Quality Management (TQM) and ISO 9001/14001 standards
Use alternative, sustainable raw materials to reduce costs without sacrificing quality.
For Regulators (KEBS, NCA)
Increase market surveillance and frequency of random testing
Enhance penalties for non-compliance and counterfeiting
Improve public awareness campaigns on verifying KEBS marks
For Contractors and Developers
Source cement only from certified suppliers
Perform on-site strength and quality tests before use
Maintain transparent procurement and documentation processes
For Academia and Students
Integrate quality assurance and material science into curricula
Conduct independent research on cement performance and market trends
| Stakeholder | Strategic Action Example | Expected Outcome |
|---|---|---|
| Manufacturer | Implement TQM, invest in lab equipment | Higher product quality, compliance |
| Regulator | Random market checks, stiffer penalties | Reduced substandard products |
| Contractor | Pre-use testing, supplier vetting | Fewer failures, safer structures |
| Academia | Research, curriculum updates | Knowledge transfer, innovation |

Environmental and Sustainability Considerations
The Role of Sustainable Practices
Cement production is energy-intensive and environmentally taxing. Kenyan firms are increasingly encouraged to:
Adopt environmental management systems (EMS)
Invest in afforestation and land reclamation
Explore alternative fuels and raw materials (e.g., fly ash, gypsum)
| Company | Sustainability Initiative | Impact |
|---|---|---|
| Bamburi Cement | Land reclamation (Haller Park) | Biodiversity, tourism revenue |
| ARM, SCL, MCL | Tree seedling distribution | Carbon sink, dust reduction |
| All Firms | Dust suppression, clean fuels | Lower emissions, improved air quality |
Stakeholder Collaboration and Enforcement: Turning Recommendations into Action
The Institution of Engineers of Kenya (IEK) has made it clear: the unchecked spread of substandard cement is a looming disaster for Kenya’s construction sector. As highlighted in the May 29, 2025, edition of The Standard, IEK president Eng. Bim Shamah warned that even products bearing the Kenya Bureau of Standards (KEBS) mark have shown up to a 25% reduction in compressive strength, threatening both public safety and the durability of critical infrastructure1.
How Can Stakeholders Work Together More Effectively?
Coordinated Regulatory Action
Joint Task Forces: IEK, KEBS, and the National Construction Authority (NCA) should form rapid-response units to audit manufacturers and conduct surprise inspections at points of sale.
Unified Reporting Platform: Develop a national database for reporting, tracking, and publicizing non-compliance cases, accessible to all stakeholders.
Legal Enforcement: Fast-track prosecution of offenders and publicize penalties to deter future violations.
Industry Self-Regulation
Peer Audits: Manufacturers and suppliers can conduct cross-checks and share best practices, creating a culture of transparency.
Supplier Certification: Contractors and developers should demand proof of compliance and participate in supplier vetting.
Academic and Professional Engagement
Research Partnerships: Universities and technical colleges should collaborate with industry to test cement samples and publish findings.
Continuous Professional Development: Regular workshops and seminars for engineers and site supervisors on the latest quality assurance techniques.
| Collaboration Area | Stakeholders Involved | Expected Benefit |
|---|---|---|
| Task Forces | IEK, KEBS, NCA, Police | Faster detection, swift action |
| Peer Audits | Manufacturers, Suppliers | Reduced counterfeiting |
| Research Partnerships | Academia, Industry | Innovation, early warning |
