1. INTRODUCTION
One of the direct consequences of urban development is an
Increase in impervious surface area. Over the years, vast areas
that used to be covered by vegetation and natural permeable
surfaces have been replaced by parking lots, streets and roofs,
disrupting the natural process of water infiltration into the soil.
One of the effects of this is increased runoff and flow during
precipitation.
The higher flow and rising water levels in storm sewer pipe
systems and streams can cause problems including flooding. erosion, sedimentation and pollution. In addition,
with global warming, the frequency of events involving heavy rains and accelerated snowmelt is more pronounced.
It stherefore important to rapidly seek new solutions.
TECH 0-B LOC permeable paver systems reduce the volume of water directed to the mun iclpal system and, as such,
are viable solutions for better stormwater management. Permeable paver systems reduce runoff and improve the
quality of water returning to the environment. Water seeps through the paving stone joints and is then directed into
the ground, or stored temporarily in the base/subbase structure.
The U.S. Environmental Protection Agency (EPA) recognizes permeable pavers as a management practice for
stormwater and as a low impact development (LID) practice.
TECHO-BLOC is a company dedicated to the development and innovation of new green products to support
sustainable development.
2 OPERATING PRINCIPLE
The role of a permeable paver system is to allow water from precipitation to pass through the paving stones joints
and seep into the ground naturally or to be retained in the base/subbase structure rather than turning into runoff
headed directly into the sewer system.
The base/subbase structure consists of a clean washed, porous stone that can collect and store water for some
time. The water can then seep into the ground in a more natural process.
In cases where soil permeability is insufficient, the water is intercepted by a network of perforated drains before
being routed to the drainage system; in this case, the system acts primarily as an underground reservoir.
The system is designed to promote water detention and infiltration. Three types of systems are used, depending
on soil permeability
Recommended in the case of soils with an infiltration rate of at least 0.491n./hr (12.5 mm/hr). All water seeps
directly into the soil; a subbase drainage pipe system is not required.
Water does not infiltrate fully. A perforated pipe system in the subbase Is required to allow the residual water
to be evacuated to the network.
DECEIVED
Recommended when soil infiltration capacity is too low or the water table is too high. Water is discharged 2019
through a system of perforated pipes and a flow restrlctor to control the entry of water into the municipal
network. The system essentially acts as an underground reservoir.

3. BENEFITS OF THE PERMEABLE PAVER & SLAB SYSTEM
Reduce the construction of additional impervious surfaces
Contribute to maintaining hydrologic conditions that
existed prior to development
Reduce runoff volume
Reduce peak flow (discharge to sewer is spread over a
longer period)
Reduce network overload:
Reduce wastewater treatment costs
Reduce the need for expensive underground retention
basins and surface retention ponds
Use In, confined spaces in existing areas requiring additional stormwater management
Reduce potential riskof erosion and flooding associated with increased runoff rates and volumes
Improve water quality
Contribute to replenishing the water table
Reduce heat islane effects (light color, high solar reflectance index (SRI). cools and humidifies surrounding air)
Gain credits for LEED certification
Improve the aesthetic quality of urban landscape
4. IMPROVED WATER QUALITY
When it rains, water runoff takes on pollutants (suspended solids, nutrients, heavy metals and other contaminants)
that are then directed to the municipal network before ending up in the waterways.
Pollutants carried by runoff have a significant impact on water quality, affecting the water supply, fish and wildlife
habitat, recreational usage and aesthetic aspects.
Permeable pavers are known for their high pollutant removal potential, which contributes to improving water
quality. Pollutants are reduced mainly by infiltration, and through several other processes. The permeable paver
system is effective for removing sediment. nutrients and heavy metals. Some studies have also shown potential
for bacterial treatment of oils.

The data were measured on King Campus at Seneca College in

presents several data from the various s!tes that show lower levels
of pollutants where permeable pavers were used.

5. TECHO-BLOC PERMEABLE PAVERS & SLABS
TECHO-BLOC permeable pavers are an alternative to traditional impervious cover. They reduce stormwater runoff
to sewer systems by promoting water detention and infiltration. They are an effective way to control stormwater
at source on residential, commercial and industrial lots. They can also minimize the need to build larger sewer
systems downstream of vacant lots being developed in an existing urbanized sector.
The permeable paver system Is the type that has been the most successful among the various types of permeable
paving avallable today. It can be used successfully in a winter climate and is less prone to clogging comparec to
pervious concrete or porous asphalt.

6. DESIGN CRITERIA
The design of a permeable paving system is based on site conditions, including, without limitation, rainfall data,
topography, soil characteristics, the height of the water table and bedrock surface, tributary runoff surface and
proximity to water supply wells.
The main factors to be considered are:
Soil infiltration rate should be at least 0.49 firl (12.5 mm/li where the system is designed for complete
infiltration.
The underside of the system must beat least 2' (0.6 m) above the water table and bedrock.
The permeable pavement system should be located at a distance of at least 98' (30 m) from water
supply wells.
The paved surface must have a grade of at least 1% and most preferably not more than 5%. The slope of
tributary runoff area should not be greater than 20%.
The ratio between the tributary runoff area and the permeable pavement area should not exceed 5 to 1.
The porosity of the clean stone composing the base and subbase should be no less than 32%, but
preferably 40%.
The percolation rate measured in situ should be understated by at least 2 to account for the long-term
reduction of the soil's absorption capacity.
A maximum drain time of 48 hours is recommended.
In situations wi rainfall is greater than the design flow rate, an overflow system directs runoff to the
drainage network.

S. FAQ
1. For what (ppe of tra,,(lic can permeable pavers be used&
In general, permeable pavers are suitable for use in low speed areas not exposed to heavy vehicles, such as
parking areas, driveways, bike paths, walking paths, patios and playgrounds.
However, TECH 0-BLOC Inflo permeable pavers are designed for applications in larger areas with higher traff Ic,
such as residential streets, parking lanes, storage areas and sidewalks.
I1 04 1 1'MM'11 ' 11 '
The absorption capacity of the system is based on the infiltration rate of the soil on the site and the clean
stone materials Coints, bedding, base and subbase). The soil infiltration rate is an indicator of potential water
infiltration directly Into the soil and determines the type of system design (complete or partial Infiltration).
The materials used in the construction of permeable pavers have higher infiltration rates than natural soil.
The initial surface infiltration rate of the permeable pavers is very high. The system allows the infiltration of
precipitation with intensity lower than the surface infiltration rate or until the water storage capacity in the
clean stone reservoir is reached, In a well -designed system, water storage capacity is rarely reached.
3. Can the permeable paver srxste'm pediimm weY in a winter climate?
Yes, ;n order to ensure their performance in winter weather, TECHO-BLOC permeable pavers are manufactured
to meet, in addition to ASTM C936, CSA A231.2-06 requirements for withstanding freezing and thawing with
de-icing salt. Experience with permeable oavers in cold c'Annates has demonstrated the absence of heaving. A
maximum drain time of 48 hours is recommended and the water that may have accumulated in the clean stone
reservoir should be evacuated within this time frame. In the event that water freezes before it is evacuated, the
space between reservoir aggregates allows sufficient room to accommodate the expansion caused by freezing
water and the risk of heaving is thereby minimized. Ultimately, the permeable paver system is flexible enough
to tolerate minor movements.
i l l /I l• I rY1 1 1 1' I
Regular cleaning will help maintain a high enough surface infiltration rate to allow rainwaterto soak through the
joints. At least one inspection and cleaning should be performed during the first year of service and thereafter
as required. Cleaning is recommended when the surface infiltration rate is less than 9.8 in./hr (250 mm/hr).
Cleaning can be done with a vacuum adjusted to minimize the removal of Joint filling material. In winter, snow
removal can be done as for any other type of paving, but It is still recommended that snow removal blades be
covered with a protective coating and raised 1" (25 mm). Permeable pavers require less de-icing material than
conventional pavement. Since melted water does not accumulate, it will not re -freeze on the surface. It is not
recommended to spread sand for :ractlon, as this may clogthe joints; instead, spread the aggregate used for
filling joints.
