When Garages Move: A Primer on Expansion Joint Systems for the Non-Engineer

你曾经看到过车库的移动吗？就像看着油漆变干一样，等着看车库的移动同样不是马上的事情。不过，停车业内人士应该知道，无论你的建筑有多大，的确是在移动中。处理好这种移动，对车库的寿命和预算非常关键。

Ever seen your garage move? Like watching paint dry, waiting for your garage to move might not be a scintillating experience. However, you should know that regardless of how massive your structure might be, it is indeed, right now, no the move. Managing that movement is critical to your deck's longevity and budget.

Parking decks move when a variety of factors such as temperature change, foundation settlement, vehicle movements, and earthquake faults continually cause minute horizontal and vertical shifts. A deck that does not properly allow for these small movements can crack and/or leak, possibly requiring extensive and expensive rehabilitation work. While expansion joint systems accommodate a structure's varied movements, they also protect the structure from moisture ingress and premature deterioration.
