Dec 1, 2005 · Non-shrink grout is a slight misnomer....it does shrink a little, but that's not the issue. Non-shrink grout is very susceptible to variations in mixing, whereas epoxy grouts are relatively foolproof. Yes, the non-shrink grout will be more brittle and lower strength than the epoxy grout (in general). Use the epoxy if cost not an issue.

Oct 16, 2015 · Agree with hokie66...would not allow pure epoxy as grout. There are some sand filled epoxies that are used as grout; however, they are not capable of such a small gap. Try BASF Masterflow 1205 grout. It is cementitious, non-shrink and has an extended set time. Stop trying to think of other materials.

Jun 27, 2005 · My contractor has decided to use Type I Cement Grout underneath the baseplates of our 5 story building rather than use non-shrink grout spec'd in our drawings conforming to ASTM C1107. We are at a point where we need to find some evidence that his grout is unacceptable. What makes it more complicated is that we are on the same team.

Jun 13, 2011 · Theoretically, there is no reason for grout under a baseplate. Theoretically, the concrete would be perfectly flat, dead-nuts level left and right and fore-and-aft (or north-south-east-west for you civil-type readers out there), and the concrete would be clean and dust free machined to a perfectly flat match with the bottom of the plate - which would of course - also …

Sep 21, 2018 · With flowable epoxy grouts, you can get down to 1/8", maybe even thinned. If you're willing to add some aggregate to cementitious grouts, the sky is the limit, but ask yourself how this impacts your ability to take loads to the foundation.

Dec 10, 2014 · In our office we use 1.5 inches of grout for 3/4" anchor bolts, and 2-2.5 inches for 1"-1.25" anchor bolts; just to allow for enough space beneath the plate for the bolts. A phone call saying there isn't enough room for the plate + leveling nuts (and plate washers if applicable) is not a phone call you want to get.

Feb 4, 2014 · The grout is just to fill the inevitable gap between the base plate and concrete. Neither concrete or steel is likely to be precisely normal to the axis of the force, or precisely at the correct level, so grout is used to make up this tolerance. It is non-shrink so that it doesn't shrink and allow the column to lower.

Nov 5, 2024 · (see Table 1, p. S-10 of ACI 530) Grout has a slump of 8" to 11", and is used to fill the cells of blocks at reinforcing. Grout must have a minimum comp. strength of 2000 psi. The most common misuse of mortar is to fill cells at reinforcing. Building Code Req. for Masonry, 1.12.1.2, says that reinforcing bars shall be embedded in grout.

Mar 7, 2017 · Most of the major non-shrink grout manufacturers, such as MasterFlow, FiveStar, etc, list a minimum application thickness, often 1". Despite how carefully I detail my design drawings, with relative frequency I have scenarios where the gap between the column base and the concrete foundation below needs reduction, sometimes down to 1/2", to ...
