# Water Seepage through Capping Beam Slab Junction
### Issue Image:
## Issue Description:
- Water from outside the boundary seeps through the gap between the capping beam and the slab.
- Often storage cages are located on the boundary and this will make the customer's belongings wet and simultaneously infuriate them.
- Detailing the capping beam with a step will stop water leaking through this junction.
## Actions to Prevent this Issue:
- check that the capping beam is detailed with a step and that the ground floor slab folds down on top to make sure water doesn't leak through this junction.
