Are shims structural?

Structural plastic shims have consistent thicknesses, and are often color-coded, which simplifies installation and inspection in the field. The shims are also stackable. Some products can fit virtually any size joint just by combining standard sizes.

What is the purpose of shims?

To fill gaps: Whenever there is a gap in materials, a shim can be used to close that gap and make the materials flush or level. Filling gaps is a common use of shims, especially in construction. If parts are subject to wear, filling the gap with a shim will stop wear from occurring.

Where are shims used?

How much weight can a shim hold?

A 3.5-inch-square Doug fir shim at the top of a 4×4 post in a crawlspace can take approximately 7,656 pounds of load (625 x 3.5 x 3.5 = 7,656 pounds) as long as the shim seats perfectly. That’s a lot of load — probably more than will ever be applied by a floor beam.

What happens when you use shims to build a house?

If small slivers of wood are used to fine tune the height of the beams, these shims can later “crush” under the weight of the beams once the home is constructed. Whenever a home inspector inspects the crawl space and sees crushed shims, he usually cites this as a potential problem and recommends that a foundation specialist be consulted.

Why are Foundation shims used in Dallas, Fort Worth?
