Assessment of the Use of Solid Concrete and Interlocking Stones in the Construction of Walkways in a Tertiary Institution

Abstract

Over the years solid concrete and interlocking stones have gained popularity in the construction of walkways due to their immense benefits. This study therefore assessed their usage in the construction of walkways in a tertiary institution, using the Federal University of Technology, Akure as a case study. The study, through the review of documentary evidence, personal observation and interview, assessed the level of usage of these materials within the institution, the present condition of these walkways, factors influencing the usage of these materials and the factors affecting their present conditions. The study revealed that the use of solid concrete for walkway construction is gradually fading away as most of the walkways newly constructed are done with the use of interlocking stones. This is as a result of the need for beautification and the need to meet up with present trend. The major defects associated with solid concrete walkways within the institution are cracks and breakages while that of interlocking stones are presence of vegetative growth in between voids, removal of interlocking stones and undulating walkways. The major factors responsible for these defects include; adverse weather condition, poor construction, poor usage and poor maintenance. The study therefore recommend adequate maintenance, use of underground drains beneath sub soil to allow proper draining of absorbed water, shading of concrete walkways through use of light weight covering and proper filling and compaction of sub-base to avoid underground settlement.
