Abstract

The present experimental investigation is conducted to study the cyclic response of coir-mat-reinforced sandy soil foundations and the effect of different parameters contributing to their performance using laboratory model tests. The parameters investigated in this study included various positions of reinforcement layer. The test results established the potential benefit of using coir-mat-reinforced sand foundations. The test results also showed that the reinforcement configuration/layout has a significant effect on the behaviour of reinforced sand foundation. With a layer of reinforcement, the settlement can be reduced. The inclusion of reinforcement can redistribute the applied footing load to a more uniform pattern, hence reducing the settlement.
