4. Installation Process for Underground Water Tank Covers
Step 1: Preparation
- Gather materials: mortar, 75% yellow sand cement, finishing tiles, tile glue, and joint color.
- Prepare the ground by checking the size of the light hole, the cover, and the tank lid height. Ensure the tanks ventilation hole is smaller than or equal to the lid frame size.
Step 2: Create the Tank Wall Width
The tank wall should be at least 50 mm wider than the tank lid frame and 30 mm deeper than the frame height.
Step 3: Apply Mortar
Spread an even layer of mortar, at least 30 mm thick, across the tank mouth to fully support the lid frame without gaps.
Step 4: Insert the Outer Frame
Place the outer frame with mortar, ensuring the top is flat and level with the finished floor. Avoid tension to prevent frame deformation.
Step 5: Position the Cover
Place the cover inside the lower frame and tape around the slots and keyholes to prevent cement mortar from sticking.
Step 6: Smooth the Lid Surface
Smooth the inside of the lid with light mortar to match the tile thickness. Use a flat ruler, tapping and vibrating if necessary, to eliminate voids.
Step 7: Apply Tile Glue
After the core layer dries, use tile glue and complete the joints, ensuring the cover is placed inside the frame during grouting and tiling.
Step 8: Clean and Protect
Clean the outer surface of the cover and shield it. After 3 days, the cover can be opened and used. Limit accessing the tank through the lid due to its small size use a support person if necessary.
