Foundation pocket walls chipping/roughing before grouting

Foundation pocket walls chipping/roughing before grouting

Foundation pocket walls chipping/roughing before grouting

(OP)
We are going to do pocket grouting for a compressor. The side walls of the pockets are smooth. Will the smooth walls create any adhering problem for grout material. Grout material is : Flowgrout EP(R). We have already placed the machine on foundation. So, if we want to chip side walls of the pockets we need to lift the machine away, chip the walls and again align the skid. This would be very tedious job for us. So my question is will the grout material serve its purpose with smooth pocket walls? Will the smooth walls create any adhering problem for grout material.

RE: Foundation pocket walls chipping/roughing before grouting

1 - I did a lot of anchorage like You say (more or less 400 mm deep). If the pockets have all a vertical axis even slightly inclined each other I don't see any problem. If You use a grouting material that encreases volume while drying, it is safer

2 - another solution could be to enlarge the sides of pockets in irregular way (I mean encrease the size)

Thanks robyengIT.
Yes, the pocket size is 420mm.
I couldn't understand the 2nd solution exactly. The machine is already on the foundation, so it is very difficult to do any changes in pockets.
