Techo Bloc pavers are indeed permeable, designed to allow stormwater to infiltrate through the pavement surface. These innovative pavers feature larger joint spaces and specialized aggregate layers that facilitate water percolation, mimicking natural ground processes. Techo Bloc’s permeable pavers offer significant benefits for stormwater management, reducing runoff and filtering pollutants. This article explores the permeability specifications, benefits, installation process, and maintenance requirements of Techo Bloc permeable pavers.
What Are the Permeability Specifications of Techo Bloc Pavers?
Techo Bloc permeable pavers are engineered to maximize water infiltration while maintaining structural integrity. Here are the key specifications:
Material Composition and Design Features:
- Permeable Pavers: Made from concrete with integrated spacers to maintain consistent joint spaces
- Aggregate Layers:
- Small Aggregate (2.5-10 mm): Filters contaminants and debris
- Medium Aggregate (5-28 mm): Transition layer for further filtration
- Large Aggregate (40-80 mm): Reservoir for rainwater harvesting
- Geotextile: Filter fabric separating large aggregate from underlying soil
Permeability Rates:
While exact rates are not specified, Techo Bloc permeable pavers are known for their high infiltration capabilities. For instance, the Aquastorm paver boasts “through-the-roof infiltration rates,” indicating exceptional permeability.
What Are the Benefits of Techo Bloc Permeable Pavers?
Techo Bloc permeable pavers offer numerous advantages for both environmental and practical purposes:
- Stormwater Management:
- Allow natural water seepage into the ground
- Reduce runoff to sewer systems
-
Minimize flooding risks and eliminate puddles
-
Runoff Reduction:
- Significantly decrease surface runoff
-
Contribute to more sustainable urban water management
-
Ecological Impacts:
- Filter out suspended solids and pollutants
- Reduce the need for de-icing salt
- Protect water streams from contamination
How Are Techo Bloc Permeable Pavers Installed?
The installation process for Techo Bloc permeable pavers involves several key steps and materials:
Required Materials:

- Place permeable pavers, ensuring consistent joint spaces
Estimated Labor Costs:
Installation costs typically range from $10 to $20 per square foot, including materials and labor.
What Are the Maintenance Requirements for Techo Bloc Permeable Pavers?
To ensure optimal performance and longevity, Techo Bloc permeable pavers require regular maintenance:
Cleaning Methods:
- Regular sweeping
- Periodic vacuuming or blowing
- Occasional washing with mild detergent
Maintenance Frequency:
- Seasonal maintenance is recommended
- More frequent checks after heavy rainfall or snowmelt
Potential Challenges:
- Clogging of aggregate layers or joints
- Mitigation through regular cleaning and proper installation
Recommended Maintenance Techniques:
- Use geotextile filter fabrics to prevent clogging
- Conduct regular inspections
- Avoid harsh chemicals that could contaminate percolating water
By following these maintenance guidelines, property owners can ensure their Techo Bloc permeable pavers continue to function effectively, providing long-term benefits for stormwater management and environmental protection.
