Introduction
With Kenya transforming into an infrastructural and industrial hub in East Africa, the demand for specialized bituminous products is on the rise. Oxidized bitumen or blown bitumen is a superior-performance product used in waterproofing, roofing, pipe coating, and other industrial applications. As one of the leading Oxidized Bitumen Suppliers in Kenya, we ensure consistent quality and timely logistics via the strategic port gateway of Mombasa Port.
What is Oxidized Bitumen?
Oxidized bitumen is produced when air is blown on regular bitumen at high temperatures, and thus it becomes a temperature-insensitive, elastic, and pressure-resistant product. It is solid or semi-solid at room temperatures and possesses a softer point and lower penetration, and hence is utilized in industrial-grade applications.
Why It’s Ideal for Kenya’s Climate
Kenya has wide climatic zone diversification from hot and humid coastal areas to dry inland areas. In such conditions, oxidized bitumen is most suitable because of its capacity to withstand heat flow, aging, and weathering stress. Its heat stability positions it as the most preferable for roofing, waterproofing, and industrial seal joints, especially where normal bitumen will melt or degrade.
Applications in Kenya’s Infrastructure and Industry
Oxidized bitumen is utilized across a wide range of industries in Kenya, including:
- Basement, roof, and foundation waterproofing membranes
- Pipe coating for water and oil transportation facilities
- Expansion joints and precast construction parts
- Industrial adhesive and insulation facings
- Bridge decks and airport runways
- It is because of its resistance to weather and mechanical strength that it becomes an essential part of public and private sector projects.
Supply Grades and Packaging
We offer the full range of oxidized types of bitumen like 85/25, 90/40, 115/15, etc., as per projects. Products are available in the form of blocks wrapped in kraft paper, polybags, or special wrapping and are well delivered through the Mombasa Port.
Strategic Delivery through Mombasa Port
Mombasa Port, the largest and busiest seaport in East Africa, is Kenya’s principal gateway to global trade. Its world-class infrastructure, deep water berths, and regional proximity make it the ideal location to import bulk materials like oxidized bitumen. With this port, we offer smooth customs clearance, rapid turnaround, and assured distribution to every corner of Kenya and nearby countries.
