Stormwater Problems in Residential Areas
Homeowners in Maryland are facing growing challenges with water management due to shifting weather patterns and increased urban development. Traditional hardscaping materials – like concrete driveways, standard patios, and walkways – are a big part of the issue. These surfaces block rainwater from soaking into the ground, creating a ripple effect. Even a moderate rainstorm can lead to significant runoff when residential areas rely heavily on these impermeable materials. This sets the stage for understanding how hard surfaces contribute to stormwater problems.
How Hard Surfaces Create Water Problems
Impermeable surfaces force rainwater to flow across the land instead of seeping into the soil. As this runoff moves, it collects pollutants – oil, fertilizers, and debris – that may end up in storm drains. The speed and volume of the water can erode soil near foundations, create standing water in low areas, and overwhelm drainage systems in the neighborhood. For homeowners, this often translates to flooded basements and damaged landscapes during heavy rains.
In older neighborhoods, years of development have often disrupted natural drainage systems and removed mature trees that once helped absorb rainfall. The result? A cascading problem that impacts entire communities. Maryland’s unique climate and regulatory landscape amplify these challenges, making the effects even more pronounced.
Maryland’s Weather and Local Rules
Maryland’s changing weather patterns make stormwater management a pressing concern. Andrew Der, CEP, describes the situation:
"As rising temperatures and climate change impact the rainfall patterns and stormwater runoff in Maryland, urban and riverine flooding are becoming increasingly problematic." [1]
In response, state authorities have tightened regulations. In 2021, the Maryland General Assembly directed the Maryland Department of the Environment (MDE) to update stormwater management standards using modern precipitation data. By July 2023, MDE proposed new requirements aimed at improving water quality treatment, channel protection, and flood control. These updated standards also address runoff from intense, short-duration storms and include special protections for vulnerable communities. The goal? To enhance both property-level and community-wide resilience against unpredictable weather patterns [1].
Recognizing these growing challenges underscores the importance of solutions like permeable clay brick pavers, which can help manage runoff more effectively.
How Permeable Clay Brick Pavers Work
As Maryland faces growing stormwater challenges, permeable clay brick pavers are becoming a key solution for managing water sustainably. Unlike traditional solid surfaces, these pavers allow rainwater to flow naturally through a series of layers that both store and filter it. This combination of practicality and design makes them a standout choice for water management.
Parts of a Permeable Paver System
A permeable paver system is essentially a multi-layered setup designed to filter and store water. At the top, you have the clay brick pavers themselves. These are installed with intentional gaps between them, letting water pass through the spaces rather than the pavers themselves. As Jonathan Hendy from Techo-Bloc explains:
"Contrary to popular belief, very little water ever goes through the actual paving stones (1% absorption rates for Techo products). The reason these systems achieve optimal performance is that water sheets off the surface of the paving stone, enters the open-graded aggregate joints between the pavers, and then infiltrates into the permeable foundation/base and sub-base." [2]
Beneath the pavers lies a permeable foundation made of graded aggregate. This layer not only supports the pavers but also provides storage for water in its void spaces. Below that, the sub-base adds extra structural strength and continues the filtration process. If needed, this system can connect to underdrains for additional water management.
How Water Moves Through and Gets Filtered
When it rains, water flows across the surface of the pavers and enters the open joints between them. From there, it moves into the permeable aggregate, which allows it to infiltrate the system. As the water travels downward through the layers of aggregate, pollutants like oil, sediment, and debris are trapped, creating a natural filtration process.
This system not only filters but also cools the water as it moves, helping to recharge groundwater. It’s incredibly efficient, with infiltration rates of 500–1,000 inches per hour when operating at full capacity [2]. Even if the system becomes 99% clogged, it can still handle about 5 inches of water per hour [2]. Once filtered, the clean water either seeps into the surrounding soil to replenish groundwater or flows through underdrains into stormwater systems. This seamless movement of water highlights the importance of proper installation.
Why Professional Installation Matters
Installing permeable clay brick pavers isn’t a simple task – it requires precision and expertise. Each layer must be carefully measured, compacted, and positioned to ensure the system works as intended. Professional installers take into account factors like soil type, drainage needs, and local regulations to design a system that performs efficiently.
The right materials and proper placement are critical for balancing structural stability with effective water management. Mistakes during installation – like uneven layers or poor compaction – can lead to issues such as reduced water flow, clogging, or uneven settling, all of which can undermine the system’s performance.
Moreover, professional installation ensures compliance with Maryland’s stormwater management standards and local building codes. This not only protects property owners from regulatory problems but also enhances the system’s role in managing water on a community-wide scale.
Benefits of Permeable Clay Brick Pavers
Permeable clay brick pavers offer a practical solution for managing stormwater while adding visual appeal to properties. These pavers not only help control runoff during heavy rains but also contribute to property value, require less upkeep, and align with local environmental regulations.
Water Management and Property Advantages
Permeable pavers can cut down runoff by as much as 80% [4], significantly reducing water flow and preventing problems like erosion near your home’s foundation. This also minimizes water pooling, which can harm landscaping.
As water seeps through the paver system, it captures pollutants like oil, sediment, and debris, improving water quality and replenishing local aquifers. The combination of their functional benefits and polished appearance can boost property value – an increasingly appealing feature as sustainability gains importance among homebuyers [5]. Additionally, their physical toughness makes them a long-lasting choice, as detailed below.
Durable and Visually Pleasing Design
Clay brick pavers are built to last, thanks to their high-temperature firing process, which makes them resilient even in high-traffic areas [3]. With compressive strengths between 6,000 and 8,000 PSI [4], these pavers endure over 50 freeze-thaw cycles without cracking [4].
Their natural tones and textures make them a versatile fit for various architectural styles.
"Clay brick pavers exude a charm and warmth that concrete often struggles to match. Their earthy tones and natural textures add to any outdoor space, seamlessly blending with various architectural styles and landscapes." – Glen-Gery [3]
Beyond their strength, clay brick pavers are valued for their ability to retain color. Unlike concrete, which can fade over time, these pavers keep their vibrant shades for decades with little maintenance. They come in a range of shapes, sizes, and colors, making it easy to create patterns like herringbone, basketweave, or running bond. Maintenance is straightforward – routine sweeping and occasional rinsing are usually enough, and individual pavers can be replaced without disturbing the entire installation. Here’s how they compare to other paving materials:
| Material | Expected Lifespan | Maintenance Frequency |
|---|---|---|
| Clay Brick Pavers | 25–50+ years | Every 5–10 years |
| Poured Concrete | Shorter than pavers | Every 3–7 years |
| Asphalt | Shorter than pavers | Every 2–5 years |
Supporting Local Stormwater Standards
In addition to their practical benefits, permeable clay brick pavers help meet local stormwater regulations. For instance, Maryland’s guidelines emphasize reducing impervious surfaces, and these pavers provide an effective way to achieve that goal [6]. By allowing water to seep into the ground rather than run off, they help property owners comply with water quality standards.
This design also reduces peak water flow during storms, easing pressure on municipal systems and lowering risks of flooding and erosion [7]. By filtering pollutants and managing water flow, these pavers prove to be a smart choice for environmentally conscious homeowners.

Step-by-Step Guide: Installing Permeable Clay Brick Pavers
Installing permeable clay brick pavers takes careful planning and attention to detail. While the process involves several technical steps, understanding the basics can help you make informed decisions for your stormwater management project. This guide outlines the key steps to ensure your paver system functions as intended.
Site Review and Drainage Planning
Soil testing is the first step to a successful installation. If your soil has an infiltration rate below 0.5 inches per hour (common with clay soils), you may need additional drainage solutions. On the other hand, sandy soils often offer excellent natural drainage. A soil percolation test can help confirm whether your site meets drainage requirements, such as Maryland’s standard for a 2-inch rainfall.
Grading analysis ensures water flows away from structures safely. The ideal slope should be between 1% and 5% – steep enough to avoid standing water but gentle enough to allow proper infiltration. If your slope exceeds 5%, terracing may be necessary to manage water flow effectively.
Drainage planning involves mapping the site’s water flow and pinpointing potential problem areas. Be sure to locate and mark underground utilities before starting any excavation. Your design should also include overflow routes to handle heavy rainfall, directing excess water to safe discharge points instead of toward buildings or neighboring properties.
Installation Process by Layer
Excavation depth depends on soil conditions and the intended use of the area. For walkways, an 18-inch depth is usually sufficient, while driveways may require up to 24 inches. Always extend the excavation about 6 inches beyond the edges of the planned paver area to accommodate edge restraints.
Subbase preparation involves adding a 12-inch layer of clean, angular stone aggregate (1.5 to 2.5 inches in diameter). Compact this layer in 4-inch increments until it reaches 95% density. This subbase provides structural support and creates void spaces for water storage and infiltration.
Bedding layer installation comes next, with a 2-inch layer of smaller aggregate (0.25 to 0.5 inches in diameter). Unlike the subbase, this layer is left uncompacted initially to allow the pavers to settle properly. Ensure the surface is level and evenly spread across the area to maximize water infiltration.
Paver placement follows a pre-determined pattern, starting from a straight edge and moving systematically across the site. Each paver should fit snugly against its neighbors, with joint spacing built into the design. Use a rubber mallet to set the pavers securely without causing damage.
Joint filling involves sweeping fine aggregate or specialized permeable jointing material into the spaces between the pavers. Fill the joints completely, but avoid letting the material spill onto the paver surfaces. A rubber-pad plate compactor can help seat the pavers and joint material securely.
Maintenance Tips for Long-Term Performance
Proper upkeep is essential for ensuring your permeable paver system continues to perform well over time.
Regular cleaning is crucial to prevent debris from clogging the joints and reducing infiltration. Sweep the surface monthly to remove dirt, and pressure wash annually to maintain water flow. Avoid using sand or fine materials near the pavers, as these can migrate into the joints and compromise permeability.
Joint material replacement may be needed every 3 to 5 years. Over time, fine particles can wash away or settle deeper into the system. Replacing the joint material with fresh aggregate helps restore the system’s water infiltration capabilities. Simply sweep out the old material and refill the joints with clean aggregate.
Seasonal inspections are a good way to catch potential issues early. In spring, check for winter damage or joint material loss. In fall, clear away leaves and debris to prevent clogging during winter. For ice and snow removal, use plastic shovels instead of metal tools to avoid damaging the pavers.
Performance monitoring helps you identify problems before they escalate. If puddles remain for more than 24 hours after rainfall, it’s a sign of clogging. In such cases, professional maintenance services can use vacuum extraction to remove sediments from deep within the joints. Regular care ensures your paver system continues to manage water effectively for years to come.
