Road infrastructure plays a critical role in economic growth, accessibility, safety, and long-term development sustainability. Properly engineered road networks enhance mobility, reduce maintenance costs, improve traffic flow, and increase the lifespan of infrastructure investments.
At Cadreatech Engineering Services Ltd, we provide comprehensive road design and pavement engineering services in Kenya and across East Africa. Our team delivers technically robust, standards-compliant, and cost-efficient roadway solutions for residential estates, county roads, industrial developments, commercial facilities, institutional campuses, and infrastructure projects.
We combine geometric road design, pavement thickness analysis, traffic loading assessment, drainage integration, and advanced modelling tools to deliver practical and durable road infrastructure tailored to Kenyan conditions.

Pavement design and material specification
-
Estate access road design
-
County road design
-
Industrial pavement engineering
-
Parking lot design
-
Institutional roadway networks
-
Road rehabilitation and upgrading
Our designs follow Kenyan road design manuals and regional pavement engineering standards, ensuring smooth approval processes and regulatory compliance.
Road Geometric Design
Geometric design forms the backbone of any road project. It ensures that the road alignment supports safe vehicle movement, adequate sight distance, and proper drainage while minimizing construction costs.
Our geometric road design services include:
Horizontal Alignment Design
We determine optimal road curvature, turning radii, and transition curves to ensure safe and comfortable vehicle movement.
Vertical Profile Design
We design gradients and vertical curves to accommodate terrain variations while maintaining safe stopping sight distances and proper drainage.
Cross-Section Design
Our engineers develop cross-sections incorporating carriageways, shoulders, pedestrian walkways, and drainage elements.
Junction & Access Road Design
We design intersections, roundabouts, and access roads for residential estates, commercial developments, and industrial facilities.
Sight Distance & Safety Analysis
We evaluate stopping sight distance, overtaking visibility, and pedestrian considerations to enhance user safety.
Using AutoCAD Civil 3D and corridor modelling tools, we create accurate road models, profiles, and quantity take-offs to improve project predictability and reduce redesign risks.
Pavement Engineering & Thickness Design
A well-designed pavement system ensures durability, structural integrity, and long-term performance under traffic loading and environmental exposure.
At Cadreatech, pavement design begins with subgrade evaluation and traffic analysis.
Traffic Loading Analysis
We evaluate expected traffic volumes and equivalent standard axle loads (ESALs) to determine pavement thickness requirements.
Subgrade Investigation & CBR Analysis
We assess soil bearing capacity, conduct CBR-based pavement design, and recommend subgrade improvements where necessary.
Flexible Pavement Design (Asphalt Roads)
We design multi-layer asphalt pavement systems, including:
-
Subgrade preparation
-
Sub-base layer
-
Base course
-
Asphalt binder and wearing course
Flexible pavements are ideal for estate roads, access roads, and county road networks.
Rigid Pavement Design (Concrete Roads)
For heavy traffic loading areas, we design reinforced or jointed concrete pavements suitable for:
-
Industrial yards
-
Warehouses
-
Heavy-duty access roads
-
Loading bays
Block Paving & Interlocking Systems
We design block paving solutions for residential estates, parking areas, and pedestrian-friendly environments.
Industrial & Heavy-Duty Pavements
For facilities experiencing heavy truck movements and container stacking, we provide specialized pavement solutions engineered for high load resistance and durability.
Our pavement engineering designs prioritize lifecycle cost optimization, material efficiency, and long-term performance.
Road Drainage Integration
Effective drainage is essential to pavement longevity. Poor water management is one of the leading causes of pavement failure.
Cadreatech integrates comprehensive drainage design into every road project.
Our road drainage engineering includes:
-
Side drains
-
Concrete channels
-
Culvert design
-
Cross-drainage structures
-
Stormwater collection systems
-
Erosion control measures
-
Outfall and discharge design
We coordinate drainage elements with pavement layers and geometric profiles to prevent water stagnation, subgrade weakening, and structural damage.
Parking Lot & Yard Design
Parking areas and industrial yards require specialized engineering due to repetitive loading and drainage challenges.
Our services include:
-
Parking bay layout design
-
Heavy-duty yard pavement design
-
Turning radius analysis for trucks
-
Surface grading for water control
-
Concrete and block paving specification
These systems are engineered to withstand high traffic volumes and minimize cracking and settlement.
Road Rehabilitation & Upgrading
Cadreatech also provides road rehabilitation and improvement solutions for existing road networks.
Our scope includes:
-
Pavement condition assessment
-
Structural overlay design
-
Surface treatment recommendations
-
Drainage correction
-
Widening and realignment design
We evaluate structural failures, cracking patterns, rutting, and drainage issues before recommending technically sound rehabilitation strategies.
Engineering Tools & Modelling Capabilities
To ensure precision and efficiency, our engineers utilize advanced engineering tools, including:
-
AutoCAD Civil 3D
-
Corridor modelling software
-
Traffic loading calculation models
-
Quantity take-off tools
-
Pavement design spreadsheets
-
Digital terrain modelling (DTM)
This allows us to produce accurate road corridors, profiles, cross-sections, and material schedules for construction implementation.
Regulatory Compliance & Standards
All our road design and pavement engineering services comply with relevant Kenyan standards and regulatory frameworks, including:
-
Kenya Roads Board (KRB) guidelines
-
Kenya Rural Roads Authority (KeRRA) standards
-
Kenya National Highways Authority (KeNHA) requirements
-
Ministry of Transport, Infrastructure, Housing and Urban Development (MoTIHUD) manuals
-
County Government approval requirements
We ensure documentation and submissions meet approval criteria for both private and public sector projects.
