Epoxy Grout

Epoxy Grout

Epoxy Grout

(OP)
I will install threaded anchor bolts (1" diameter F1554 55, post installation) and try to use Sikadur 32, Hi-mod epoxy grout. I am unable to find the following information on the Sika Corporation web site.
1. What size of hole for 1" anchor rod?
2. Does Sikadur 32, Hi-mod have Freeze Thaw issue?
3. Is Sikadur 32 for short term loading or for long term loading (i.e. 30 years)?

Could someone provide some your experience and opinions on above issues? Thank you.

RE: Epoxy Grout

I suggest you contact your Sika representative, but I don't believe this material is intended for use in installing anchors.

RE: Epoxy Grout

agree with hokie,

Also epoxies are no suitable for sustained long term loading as they are susceptable to creep.

RE: Epoxy Grout

(OP)
Thank you.
I reviewed a lot of Sika information in internet. The old Sika specification stated that it is for grout bolt, rabar, etc. But the current Sika documentations are not stating it is for grouting bolts, rebar. So I concern that this product may have some issues in the past. I did call Sika Repesentative but I am unable to get enough information to make decision. So I come here to have some opinions.

If I am not using Sikaur 32 Hi-Mod, I may use Sikaur 328 cement based grout. I am right now only have some knowlege and experience on Sika grout. Could you please provide me some experience on Sika 328 grout or some other manufacturer products?
Thank you again.

Look at the Hilti epoxy products: Hilti HIT-HY 150 or HIT RE 500.

RE: Epoxy Grout

I don't know what Sika was thinking with the new website.  I find it far more difficult to find technical documents compared to the old version.

RE: Epoxy Grout

This may have something to do with the fatal collapse of the ceiling slabs in the Boston tunnel.  The epoxy was made by Sika, but packaged and sold by Powers Fasteners.  The material was found to be the wrong type for sustained tension loading, if indeed there is a right type.

Sika is not a fastener company, it is a chemical company.

RE: Epoxy Grout

I second the suggestion to look at a Hilti product.  Their design information is more comprehensive and the support is the best I have seen.  They also have products ICE and the RE500 which are recommended for temperature issues and sustained loading.
