Waterproofing interrupted at the footings
High- Cause:
- Each part done separately without joining.
- Impact:
- A weak point where moisture gets in.
Stage 3: Waterproofing WorksTie Beam Waterproofing
Tie Beam Waterproofing
Before Backfilling
Tie beam waterproofing protects the ground beams from soil moisture and salts, and stops moisture reaching the ground floor walls. We inspect it once, before backfilling.

What Is Tie Beam Waterproofing?
Tie beam waterproofing is a layer applied to the faces of the ground beams that are in contact with soil. The tie beam waterproofing inspection is an engineering visit before backfilling, in which our engineers make sure the waterproofing covers every face and is applied correctly.
The inspection matters because the tie beams carry the ground floor walls. If moisture reaches them, it rises into the walls and shows up as stains and peeling paint near the floor, and over time it can cause the rebar to rust.
Handover of Tie Beam Waterproofing
We inspect the waterproofing once, after it is applied and before backfilling.
Single Inspection
Book This Inspection
Tie Beam Waterproofing
When: After the waterproofing and protection layer are applied, and before backfilling.
The last chance to see the waterproofing before the soil covers it. We make sure it fully covers the beam faces, has the right thickness, and has no gaps or tears.
Key Items We Inspect
Surface Preparation
Concrete is clean and dry before waterproofing.
Coverage
All faces in contact with soil are covered.
Thickness
Waterproofing thickness measured with a thickness gauge.
Overlaps
Overlap lengths between rolls or layers.
Junction With Footings
Waterproofing continues where the beam meets the footing.
Protection Layer
In place before backfilling to protect the waterproofing.
Most Common Problems at This Stage
Thickness below requirement
High- Cause:
- Saving on materials.
- Impact:
- Shorter waterproofing life and moisture leakage.
Backfilling without protection
High- Cause:
- Skipping the protection layer.
- Impact:
- Waterproofing torn by gravel during backfilling.

Tips Before the Inspection
To help you get more out of the visit.
Do
- Request the handover before backfilling starts.
- Make sure the contractor has applied the protection layer.
- Have the required waterproofing specifications ready if available.
Avoid
- Backfilling before the waterproofing is inspected.
- Accepting waterproofing applied on damp or dirty concrete.
- Dropping materials or walking on the waterproofing.
Frequently Asked Questions
Common questions about Tie Beam Waterproofing.
Why is tie beam waterproofing important?
Because moisture that reaches the tie beams rises into the ground floor walls, showing up as stains and peeling near the floor.
When should I request the inspection?
After the waterproofing and protection layer are finished, and right before backfilling.
How much does a tie beam waterproofing inspection cost?
From 700 AED.
