Is grout required under base plates?
What Is the Purpose of Grout Under Base Plates? Grout acts like a liquid shim between two surfaces and is used to secure the base plates of heavy machinery to the foundation which allows the machinery to function properly.
What is the minimum thickness of base plate?
A minimum thickness of 12 mm is recommended for posts and lightly loaded columns, while 20 mm minimum thickness is recommended for normal applications (after Ref. 7). Preferred plate thicknesses for the base plate are: 12, 16, 20, 25, 28, 32, 36, 40. Base plates are typically cut to size using thermal processes.
How do you grout under base plates?
grouting underneath steelwork and steel baseplates
- Step 0 – Shims used to temporarily level baseplate & steelwork.
- Step 1 – create a formwork around the baseplate.
- step 2 – use a hopper and pour in the grout.
- Step 3 – Wait for non-shrink grout to go off then remove formwork.
- step 4 – chamfer off corners on exposed edges.
How thick can you grout?
There is no standard for grout joints. According to the TCNA, the grout width can vary depending upon the size of the tile. Many stone and tile manufacturers suggest that grout joints be no less than 1/8″ to 3/16″.
What is the minimum grout line?
1/16”
Grout lines need to be at least 1/16” for the grout to even fit, and often larger than that depending on a variety of other factors. For some grouts, like sanded cement grout, 1/8” is the minimum line size.
What is the size of base plate?

How do you find the thickness of a base plate?
The thickness of base plate has been determined by equating moment due to upward pressure at critical section of base plate to the flexural (bending) strength of base plate.
How thick can you pour grout?
2.3. ACI 351.1R-99 requires a minimum thickness of 25 mm for flow-able hydraulic cement grout placed by gravity. When the flow length is larger than 300 mm, the thickness should be increased by 13 mm for each additional 300 mm to a maximum of 100 mm.
What is the maximum grout thickness under base plate?
Different grout strengths ranging from poor (5.6 MPa) to high grout strength (50 MPa) are considered. The thicknesses are selected based on the most common ones found in engineering practice (ranging from 25 mm to 100 mm).
What happens if grout is too thick?
Grout that is too thick won’t fully seal the tile because it’ll be too thick to reach the bottom of the cracks. Overly thick grout can also stick to the surface of the tiles and is difficult to remove when the job is done.
How thick is grout under tile?
As a general rule, floor tiles should have grout lines of 1/8 inch or larger, depending on the type and size of tile. Special types, such as slate or quarry tiles, often do not have edges uniform enough to work with tight spacing. These tiles usually are spaced with grout lines 3/16 inch or wider.
Why grout under base plates?
Grouting Base plates. Grout is installed under columns to create a firm, even foundation for the column to bear on. When a shear key is not installed, the grout transfers shear loads through friction to the footing. The grout also acts as protection for the anchor bolts which are used to ‘hold down’ a structure from various loads i.e. wind loads.
What is standard Grout size?
The Tile Council of North America and accompanying tile organizations recommend an average grout joint width of 3/16 inch for every 1/16 inch variation in the size of the tiles.
What is a steel column base plate?
Steel column base plates are one of the most ~ndamental parts of a steel structure, yet the design of base plates is commonly not given the attention that it should by engineers. This results in base plate details that are expensive, difficult to fabricate and may even contribute to the hazards
