AI Technical Summary

Benefits of technology

The present patent meets the need for a durable seal between adjacent panels by providing a foam-based expansion joint seal system. This system can be longer in length and shipped conventionally, ensuring constant and equal compression throughout the system. Additionally, it prevents the loss of large sections of material.

Problems solved by technology

Moreover, these joints are subject to damage over time.

Most damage is from vandalism, wear, environmental factors and when the joint movement is greater, the seal may become inflexible, fragile or experience adhesive or cohesive failure.

Unfortunately, this is applied to each stick, which is limited in length due to shipping sizes, typically to six to ten foot sections.

As a result, during shipping, the stick may be subjected to bending forces, such as when loaded on a truck over other materials, which causes the shrink wrap to crack or fail along a seal, permitting the compressed product to expand through the resultant opening and rendering the product unusable.

Because the packaging is sized for conventional shipment, the sticks are typically limited to not more than ten (10) feet.

Even with the size limitation the sticks are too long for easy handling which can result in damage in transit or added delivery fees.

With the roll, because any compression is generally radially as each successive layer is deposited, compression is possible in only one direction, but difficult to control over time due to the varying radius of the material and the potential for localized areas of higher or lower compression.
