![]() This process creates a space for the application of the sealant material. Specifically, builders use a filler with a removable top portion, or customize it during forming. In addition to the compressible filler, these gaps generally contain a sealant on top. This is significantly important since the intrusion of such materials can limit the effectiveness of the joint. These incompressible materials include dirt, debris, sand, etc. Hence, after pouring, this gap containing the filler will separate the garage slab from the wall or other adjoining elements, and isolate their movements.īesides, the compressible filler not only aids in forming the gap, but also in preventing foreign materials from entering it. How is the gap between your garage floor and wall created, and what does it contain?īased on the construction sequence of structures which generally contain these gaps in design, a compressible filler is placed at the interface where the garage floor meets the existing concrete, before pouring. Accordingly, such gaps do not permit any continuity in reinforcements and do not contain dowels. Hence, its purpose is to isolate elements, and allow for movements without restrictions. This type of concrete joints represents a full depth gap which completely separates two elements. However different widths are also common, depending on the design. Usually, it is a 3/4 to 1 inch gap between the basement floor and wall. ![]() In this case, they generally isolate the floor using a perimeter isolation joint. To illustrate, the contractor pours the footings first, then the walls and/or columns, and then the floor. In this case, it has no connections to other structural members. In addition, it can be also related to the casting sequence.įor example, engineers sometimes design the slab-on-ground garage floor as a separate member. In fact, in some cases, this joint is a fundamental part of the design. The gap is technically a joint, and in specific an isolation joint. What is that gap between your garage floor and wall? ![]() This article thoroughly addresses the major details behind this gap, and provides a step by step procedure on how to seal it. Ever wondered what that gap between your garage floor and wall is? Why it is there? And if does require any maintenance?
