Seal Coating |
Seal coating protects your pavement while providing a
jet black finish that keeps it looking great. It can be
applied by a spray application as well as hand
application.
In order for seal coating to do its job, any structural
failures or cracks must be repaired in advance. Next we
can seal coat your pavement with two coats of coal tar
emulsion sealer in the following manner.
• First
we sweep the pavement surface with a power broom and
blow off all of the dirt, dust and debris with heavy
duty air blowers. All bad petroleum stains are primed
with a special bonding agent to allow the sealer to
adhere in these areas.
• Next,
two coats of sealer are spray applied onto the pavement
for uniform coverage. We can coat from 6,000 to 10,000
square yards with two coats in a single day, depending
upon the location and access.

Seal coating is very important in maintaining
structurally sound pavements for the following reasons:
• Gas
and oil can penetrate into the asphalt and break it down
prematurely. This is because asphalt is also a
petroleum based product. The gas or oil dissolves the
asphalt binder that holds asphalt together. Coal tar is
impervious to gas and oil and it keeps damaging fluids
away from the asphalt allowing the rain to wash the
pavement clean.
• Structurally
sound pavements can dry out prematurely from the sun's
ultraviolet rays. It makes the asphalt cement brittle
and as a result the asphalt fines and then the larger
aggregate can ravel away. The coal tar forms a tough
bond that does not allow the UV rays from the sun to
penetrate into the pavement.
• Once
the pavement has been weakened from the above two
conditions, water can wash away the aggregates that are
the strength of any pavement.
• Asphalt is not a completely waterproof
substance. If water is left sitting on the pavement it
can penetrate into the sub-base causing premature
pavement failure. The coal tar reduces these affects by
making the pavement much more waterproof and the jet
black color raises the temperature of the pavement
making water evaporate more quickly and makes ice melt
more quickly in the winter. |
