Step 3: Grout fill

Grout fill the remaining voids (See Figure 8), both at the bottom (See Figure 9) and laterals of the penstock (See Figure 10).  

Remember that the objective of the grout fill is twofold:

• 

Fill the voids between the frame, frame invert and the channel.

• 

Make a smooth transition for water flow. Therefore, the grout shall be built-up to the level of the frame as shown in Figures 

9 and 10.

CAUTION! Make sure not to get grout or any other foreign material on the seals, guides or stem as this may cause leakage or 

damage.
