Water Permeable Paver Block

Abstract

Water permeable paver blocks are a sustainable pavement solution that allows rainwater to pass through the surface and enter the ground. Unlike conventional concrete pavements, they reduce water logging, surface runoff, and urban flooding while improving groundwater recharge. In this project, permeable paver blocks are made using cement, coarse aggregate, minimal fine aggregate, water, and admixtures. Their performance is evaluated through tests like compressive strength, permeability, and durability. These blocks are suitable for low-traffic areas such as parking spaces, footpaths, and gardens, promoting eco-friendly construction practices.

Introduction

Rapid urbanization has increased the construction of roads, parking areas, and footpaths using conventional concrete, which does not allow rainwater to seep into the ground. This leads to problems such as water logging, flooding, and reduction in groundwater levels. To address these issues, water permeable paver blocks have been developed. These blocks contain small voids that allow rainwater to pass through them and infiltrate the soil, helping in groundwater recharge, reducing surface runoff, and minimizing flooding. They are made using cement, coarse aggregates, water, and admixtures with little or no sand, making them an eco-friendly and sustainable pavement solution suitable for parking areas, footpaths, gardens, and low-traffic zones.

The project aims to design and study permeable paver blocks that provide sufficient strength while allowing water infiltration. The objectives include reducing water logging, promoting groundwater recharge, lowering pressure on drainage systems, and supporting sustainable construction practices.

The methodology involved producing permeable paver blocks using OPC 53 grade cement, 10 mm coarse aggregates, water, and UltraTech WP+200 admixture. The blocks were cast in 12 × 12 × 3 inch molds, demolded after 24 hours, and cured for 7 and 14 days. Several laboratory tests were conducted to evaluate the materials and performance, including standard consistency test, impact test, abrasion test, slump cone test, compaction factor test, compressive strength test, and flexural strength test.

Results showed that normal concrete has higher compressive strength, while permeable concrete has lower strength due to its porous structure. The compressive strength of permeable concrete was 10.9 N/mm² at 7 days and 14.8 N/mm² at 14 days, which is adequate for light to medium traffic areas. Flexural strength tests showed values around 3.0–3.3, indicating sufficient resistance to bending for pavement applications.

The estimated cost for producing the permeable paver block materials was approximately ?1650, including cement, aggregates, admixtures, and molds.

Conclusion

Permeable concrete blocks are an eco-friendly pavement solution that allows rainwater to pass through their porous structure, reducing surface runoff and water logging. They help in groundwater recharge and support sustainable water management in urban areas. Although their strength is lower than conventional concrete, they are suitable for low-traffic applications like footpaths and parking areas. Proper mix design, curing, and regular maintenance ensure durability and long service life. Overall, permeable concrete blocks promote sustainable and cost-effective infrastructure development.
