Pump Skid Grout Recommendation

Pump Skid Grout Recommendation

Pump Skid Grout Recommendation

(OP)
We are working on vibration problem for a 2500 hp skid mounted pump-motor assembly.  The skid has 12" deep cavities between the top plate and bottom plate, for filling with material to stiffen the skid and increase the mass.  The cavities have only had sand fill so that the skid could be relocated.  To provide more stiffness, we wish to fill them with grout now.

The side runners are 16" WF, the intermediate crossmembers are 12 WF, and the top and bottom plates are 1/2" forming the 12" cavity.

What grout products have been specifically made or successfully proven in this usage?  Cost is of course a consideration.  We are leaning toward cementitious grouts due to cost but are open to epoxies or other resins if necessary to do a good job of resisting vibration.

RE: Pump Skid Grout Recommendation

The epoxy grouts seem to work better long term, although initial cost is higher, the shrinkage is less. You need to sandblast or prep the skid so either grout will adhere. If you still plan to drag the skid around, you might consider welding rebar or other struts inside the cavity to tie the sides together and prevent the grout from pulling loose.

Otherwise just follow the grout instructions on the container.
