NBRRI Sub-Graded Soil Atlas of Nigeria

Nigerian Building and Road Research Institute (NBRRI) recognizes the crucial role of understanding soil properties for safe and sustainable construction practices. To this end, NBRRI developed the Sub-Graded Soil Atlas of Nigeria, a comprehensive resource that empowers engineers and construction professionals across the nation.
Regional Coverage

The Atlas incorporates data on sub-graded soil properties from various locations across Nigeria, ensuring comprehensive geographical representation.

Detailed Soil Information

Comprehensive profiles for each identified soil type, including physical and chemical properties, bearing capacities, and potential challenges or benefits for construction.

Mapping and Visualization

The Atlas effectively utilizes maps and illustrations to present the spatial distribution of various soil types and key soil properties.

Guidelines for Use

Practical advice on interpreting atlas data for planning and design purposes, tailored to different regions and types of construction.

What is the Sub-Graded Soil Atlas of Nigeria?

This Atlas serves as a vital reference tool, providing detailed information on the sub-graded soil characteristics across various regions of Nigeria. Sub-graded soil refers to the soil encountered below the topmost organic layer and significantly influences foundation design and overall construction stability.
  • Facilitate Improved Infrastructure Development: By providing detailed information on soil types and their properties, the atlas aids in the design and construction of more durable and cost-effective infrastructure.
  • Support Educational and Research Endeavors: Serve as a vital resource for academic institutions and research organizations, enhancing the study and understanding of geotechnical engineering and related fields.
  • Aid in Policy Making and Planning: Offer policymakers and planners valuable data to inform decisions regarding land use, environmental conservation, and infrastructure development.
  • Promote Sustainable Construction Practices: Encourage the use of local materials and techniques suited to specific soil conditions, fostering sustainability in construction projects.
