Waterproofing is a critical component of construction and building maintenance, especially in a region like Dubai where extreme temperatures, humidity, and occasional rain can create major structural challenges. Among the many waterproofing techniques available, cementitious waterproofing in Dubai UAE stands out as a popular and reliable choice. But what exactly is it, and how much does it cost? This blog explores the types, benefits, cost factors, and application process of cementitious waterproofing, especially with regard to concrete structures and concrete repair in Dubai UAE.
What is Cementitious Waterproofing?
Cementitious waterproofing is a process where cement-based materials are used to prevent water infiltration into surfaces such as concrete walls, foundations, basements, and water tanks. The compound used is a mix of cement, sand, and proprietary additives that improve flexibility and adhesion. When applied to a concrete substrate, it creates a barrier against water, moisture, and certain chemicals.
This method is especially effective for below-ground structures, wet areas like bathrooms, water tanks, and in some cases, roofs and terraces.
Why Cementitious Waterproofing is Popular in Dubai
Dubai’s climate includes intense heat for most of the year, with occasional heavy rains that cause water accumulation. As a result, buildings are at risk of moisture-related issues like cracks, damp patches, and concrete degradation. Cementitious waterproofing in Dubai UAE is widely adopted due to:
- High durability
- Ease of application
- Resistance to positive and negative hydrostatic pressure
- Compatibility with concrete repair in Dubai UAE
Moreover, the method is cost-effective compared to many modern alternatives, which makes it a preferred choice for both residential and commercial applications.
Types of Cementitious Waterproofing Systems
Before diving into the cost, it’s essential to understand the types of cementitious waterproofing systems:
1. Rigid Cementitious Systems
These are ideal for structures that are not subject to movement or flexing. They are typically used in internal wet areas like bathrooms, water tanks, and swimming pools.
2. Flexible Cementitious Systems
Formulated with additional polymers, these systems offer better flexibility and crack-bridging ability. Suitable for areas exposed to thermal movement, such as terraces and external walls.
3. Crystalline Waterproofing
This system works by creating crystals within the pores and capillaries of the concrete, blocking water pathways permanently. It is often used for deep foundations and water-retaining structures.
Average Cost of Cementitious Waterproofing in Dubai
The cost of cementitious waterproofing in Dubai UAE varies depending on several factors such as the type of system used, surface area, application complexity, and site conditions. Below is a general cost breakdown:
1. Material Cost
- Rigid Cementitious System: AED 10 to AED 15 per square meter
- Flexible Cementitious System: AED 15 to AED 25 per square meter
- Crystalline Waterproofing: AED 20 to AED 30 per square meter
2. Labor Charges
Labor typically ranges from AED 8 to AED 15 per square meter, depending on the contractor’s expertise and project complexity.
3. Total Installed Cost
When material and labor are combined, the total cost of cementitious waterproofing in Dubai UAE can range from AED 18 to AED 45 per square meter.

Cost Influencing Factors
Several variables can affect the overall pricing of cementitious waterproofing in any project. Let’s look at the most common ones:
1. Type of Structure
A basement, swimming pool, or water tank has different waterproofing needs compared to a bathroom or terrace. Structures under high hydrostatic pressure usually require more advanced and costly systems.
2. Surface Condition
Cracked, uneven, or damaged surfaces may require pre-treatment, grinding, or concrete repair in Dubai UAE, increasing the total cost.
3. Accessibility
If the waterproofing area is difficult to access—like underground tanks or high-rise balconies—the labor cost may be higher due to scaffolding or safety gear requirements.
4. Water Pressure
Areas exposed to negative water pressure (like the inner face of retaining walls) often need more robust waterproofing, which can raise the cost.
5. Thickness of Application
Thicker coatings are required in high-risk areas, which increases material consumption and time.
6. Warranty or Guarantee
Some waterproofing contractors offer extended warranties, which might slightly increase the initial cost but offer peace of mind in the long run.
Application Process: Step-by-Step
To better understand where the costs go, it’s useful to look at how cementitious waterproofing is applied:
Step 1: Surface Preparation
The area is cleaned thoroughly, removing dust, oil, paint, or any contaminants. Damaged concrete is fixed using appropriate concrete repair in Dubai UAE solutions.
Step 2: Priming
A primer or bonding agent may be applied to enhance adhesion of the waterproofing compound.
Step 3: Mixing
The cementitious waterproofing material is mixed with water or a polymer liquid to the recommended consistency.
Step 4: Application
The mixture is applied using a brush, trowel, or spray in one or more coats, depending on the product and area conditions.
Step 5: Curing
The applied area must be protected from sun and wind and kept moist for curing, usually over 3–7 days.
