creep is a phenomenon that is occurring in concrete streets
from street creep occurs as a result of nature’s
uncontrollable affect on concrete slabs and joints.
When considering street creep, nature affects concrete
slabs two different ways, gravity and thermal (temperature
change) expansion and contraction.
The first natural affect, gravity, literally causes
streets to move or slide toward homes.
This movement of concrete slabs from gravity is the most
person can predict when and where the concrete slabs will move.
The most common locations are hills and street curves.
Also, there is no definite way to predict how far these
streets will move. Conventional
expansion joints (fiber and wood) are not wide enough to allow
the vast amount of movement of streets towards homes.
The second natural affect is thermal expansion and
expansion and contraction occurs when the temperature changes
over the course of a year. Everything
in nature expands and contracts when temperatures increase and
expansion joints (fiber and wood) deteriorate and allow rock and
grit to settle into the joint during the colder months when the
concrete is contracted. The
rock and grit remain trapped in the joint when the concrete
expands in the warmer months.
This dirt and grit does not allow any expansion and
causes the forces from the slab to increase.
From these natural affects on concrete a chain reaction
occurs as follows:
slabs move toward homes exceeding the amount of conventional
expansion causing the pressure between the slabs to increase
expansion material deteriorates allowing uncompressible
material into the joint eliminating any space for expansion.
expansion occurs from the warmer temperature causing the
pressure between the joints to increase uncontrollably.
pressure between the slabs causes the garage floor slab to
push against the front, back and side foundation walls.
foundation wall that is not designed to handle these forces
cracks uncontrollably. Your
home in the blink of an eye has depreciated in value.
is no way to control nature.
We can only prepare for what nature will bring.
Our seamless, extruded, rubber expansion joint has been
specifically designed to protect your home from natures
potential. The only
way to prepare your concrete for nature’s potential is to
install our expansion joint.
