Porous concrete has its application in many fields. Mainly for drainage purpose porous concrete can be used as a covering as well as to drain the liquid. Strength is only drawback in the porous concrete as the surface area contact between the coarse aggregates is less. In order to enhance the strength properties, poly propylene was used in layers. Various no of layers was introduced in the prism as well as for cube to determine the strength enhancement properties. Through experimental study it was found that strength due compressive force of the pervious concrete increases up to placing 3 layers of polypropylene geo textile fabric and get decreased after that. Similar to the compression test, the flexural strength also showed similar behaviour in the increase in strength up to the 3no of layers. Similarly, porosity test was carried to find the effect of porosity due to PP layers. It was found that 18.5% reduction in porosity was noted when 3 layers of PP were incorporated.
