Masonry pavings are used in pedestrian walkways, building entrances, patios, and sometimes in driveways.
It is constructed using bricks, stones, and concrete masonry units of different shapes and colors, with adequate strength and resistance to abrasion and weathering.
These paving units are laid over a settling base spread over a base layer.
The settling bed consists of a one to two inch thick layer of sand, pea gravel, or finely crushed stone that helps level the paving units.
The rigid base layer of pavements subjected to heavy vehicular loads may be made of reinforced or unreinforced concrete.
Whereas pedestrian pathways use a semi-flexible base layer made of asphalt or bituminous concrete or a flexible base layer made of gravel or sand.
For permeable paving, rainwater falling on the pavement is allowed to pass through it and infiltrate into the soil underneath it, thereby minimizing the runoff into stormwater drains.
This is ensured by spacing the units with sand or planted soil between them or using porous pavers, such as pervious concrete or open paving blocks.

Q1: What materials are used in masonry paving construction?
Masonry paving uses bricks, stones, and concrete masonry units selected for their shape, color, strength, and resistance to abrasion and weathering. These materials are chosen to withstand pedestrian and vehicular traffic while maintaining aesthetic appeal. The units are laid over a settling base and base layer to ensure proper installation and durability.
Q2: What is the purpose of the settling bed in paving installation?
The settling bed is a one to two inch thick layer of sand, pea gravel, or finely crushed stone placed between the paving units and the base layer. Its primary function is to level irregularities in the base or in the units themselves, ensuring proper drainage and a stable foundation for the masonry paving system.
Q3: How do base layer requirements differ between pedestrian and vehicular pavements?
Pedestrian pathways use semi-flexible base layers made of asphalt or bituminous concrete, or flexible base layers made of gravel or sand. In contrast, pavements subjected to heavy vehicular loads require rigid base layers of reinforced or unreinforced concrete to withstand greater stress and provide superior load-bearing capacity.
Q4: What are the common applications for masonry paving?
Masonry paving is used in pedestrian walkways, building entrances, patios, and sometimes in driveways. These applications benefit from the aesthetic variety and durability that masonry units provide, offering both functional and decorative solutions for outdoor surfaces in residential and commercial settings.
Q5: How does permeable paving reduce stormwater runoff?
Permeable paving allows rainwater to pass through the pavement and infiltrate into the soil underneath, minimizing runoff into stormwater drains. This is achieved by spacing units with sand or planted soil between them or using porous materials such as pervious concrete or open paving blocks, reducing strain on municipal drainage systems.
Q6: What types of porous materials are used in permeable paving systems?
Permeable paving systems use porous materials such as pervious concrete or open paving blocks. These materials, combined with sand or vegetated soil spacing between conventional paving units, allow water infiltration while maintaining structural integrity and contributing to groundwater replenishment and environmental sustainability.
Q7: How does masonry paving perform under different weather conditions?
Masonry paving materials are selected for their resistance to abrasion and weathering, enabling them to withstand environmental exposure and maintain durability over time. Understanding how masonry performs in cold and hot weather conditions is important for optimizing paving design and ensuring long-term performance in your climate.
