driveway pavers can be solid pavers that are spaced in such a way as to
allow water to drain between them. These are made from stone,
concrete, brick, or decorative concrete. Others are made from concrete
that is actually porous. These pavers allow water to drain through their
entire surface. Both offer environmentally friendly benefits, with porous
pavers of course being the more effective of the two.
many things that a pervious
hardscape does for a Houston landscaping design. One of the
most important benefits that it offers is its ability to help maintain
groundwater levels. Groundwater is essential to the roots of
vegetation. In particular, trees with very large, extensive roots systems
require groundwater several feet deep to maintain their vitality.
made from an impenetrable material can cause a great deal of trouble for trees
planted to near the pavement. If a large number of their roots
grow under the hardscape, they will not receive the full amount of water.
This can result in stunted growth, defoliation, or even disease.
Permeable driveway pavers, on the other hand, will filter water straight to
these root systems. Smaller shrubs, rose bushes, and even
ornamental lawn grasses lining the driveway edge also benefit from the more even
distribution of rainwater that this type of driveway design facilitates.
driveways can be built using solid concrete or stone laid over a crushed stone
base. Crushed stone and sand are then used to fill the spaces
between pavers, creating places between the edges where water can
drives and motor courts should be built of permeable driveway pavers that are
made from porous concrete. This is often more expensive, but well
worth the investment when a very large portion of the front yard is covered by
hardscape. Porous concrete is an aggregate of stones and cement that
contains considerably less sand than other forms of concrete. This creates
tiny holes that water and air can filter through.
Air is just
as important as water to certain types of plants. Many roots need
it as much as water. Permeable driveway pavers made from porous concrete
will provide better aeration for the soil. This will help many of the
smaller, ornamental plants, and indigenous plants retain their color throughout
winter months, when we often get more rain than we do in late summer, this type
design has proven one of the most effective methods of erosion
control. Storm water can come down with such force that it
accumulates in streets faster than the storm sewers can drain it away.
Driveways flood next, and when the water recedes, soil around the driveway is
Permeable driveway pavers
will allow storm water to drain into the pavement and filter
through a foundational layer of crushed stone. This keeps water
from spilling over the pavement edge and washing away everything that surrounds
it. If there happens to be pollutants such as motor oil, antifreeze, or
other fluids that drip from vehicle undersides, these toxins will be trapped
below the crushed stone foundation long enough for bacteria to biodegrade
