Why Invest in Flat Concrete Roof Waterproofing?

Flat concrete roofs are a popular choice in South Africa for their strength and versatility, commonly found in commercial buildings, warehouses, and modern residential properties.

However, their flat or low-pitched design makes them vulnerable to water pooling, especially during heavy rainfall in areas. Combined with intense UV radiation and temperature fluctuations, flat roofs are prone to cracks, settlement issues, and failed waterproofing systems, leading to leaks, internal damage, and costly repairs.

Proper waterproofing is essential to maintain structural integrity and protect your property.

At SealPro Coatings, our flat concrete roof waterproofing services address these challenges with the Armtec HyperFlex waterproofing system, offering:

Leak Prevention

A fully bonded, seamless membrane using StretchSeal and Flex prevents water ingress at cracks, joints, and outlets. Its cold-applied, seamless application bonds directly to full-bore and PVC outlets, ensuring a durable, leak-proof seal.

Durability

The layered ArmTec HyperFlex system embeds fibre-coated Armtec Mesh to absorb shocks and movement cracks, ensuring robust protection for flat concrete roofs. The HydroSeal HF topcoat delivers a UV-stable, weather-resistant finish, reducing maintenance costs in South Africa’s harsh climate.

Versitile

The ArmTec HyperFlex waterproofing system is designed for direct application over existing sealed flat concrete roofs without removing prior systems, ensuring seamless, durable protection. It is compatible with previously sealed slabs and can be installed directly over torch-on, Derbigum, bitumen, and mineral chip torch-on surfaces, simplifying installation and reducing costs.

Customised Solutions

The ArmTec HyperFlex system excels on new and existing flat concrete roofs, seamlessly sealing settlement cracks and parapet wall junctions. Its flexible, cold-applied design adapts to any shape, bonding securely to concrete, wood, glass, tiles, and aluminium for durable waterproofing

Our Expert Flat Concrete Roof Waterproofing Process

SealPro Coatings follows a meticulous 12-step process to ensure your flat concrete roof is thoroughly protected, addressing all potential vulnerabilities with precision:

1. Cleaning the Concrete Slab

We start by thoroughly cleaning the slab, removing old or failed waterproofing, dust, and loose debris using sweeping and high-pressure washing to create a clean surface for subsequent layers.

2. Filling Cracks and Cavities

All cracks and cavities are inspected and filled with Posi Skim Filler to restore a smooth, stable surface, preventing water penetration and ensuring a strong foundation.

3. Shaping for Proper Water Flow:

Proper drainage is critical. We open full-bore outlets to ensure free water flow and use Posi Skim Filler to shape the slab’s sides, sloping them toward drains to prevent pooling.

4. Priming with Penetrar

We apply an even coat of Penetrar primer across the entire slab. Penetrar binds residual dust and promotes powerful adhesion for the waterproofing layers, ensuring a durable bond.

5. Reinforcing Joints and Settlement Cracks

Potential stress points, such as fixed cracks and joints, are strengthened with a layer of Flex waterproofing. We embed StretchSeal membrane into the Flex and saturate it with another coat for robust protection.

6. Creating Internal Wall Cement Flashings

At internal corners where the roof meets parapet walls, we install a 45° cement Fillet using Posi Skim Filler to direct water away and prevent leaks at these vulnerable junctions.

7. Positioning the Armtec Mesh

We roll out Armtec Mesh and shape it to fit the waterproofing section, ensuring complete coverage and reinforcement for the slab.

8. Embedding the Mesh with HyperFlex

HyperFlex is applied directly over the Armtec Mesh, pressed down to penetrate fully through the mesh, securing it to the slab for a seamless, reinforced layer.

9. Waterproofing Full-Bore Outlets

Full-bore outlets are sealed with the StretchSeal Flex membrane system, applied directly onto the outlet casing for a watertight finish that prevents leaks at drainage points.

10. Sealing Cement Flashings on Parapet Walls

Cement flashings are strengthened by embedding StretchSeal membrane with Flex, ensuring durability and waterproofing at parapet wall junctions.

11. Applying the First Coat of HydroSeal HF

Once the surface is dry and walkable, we apply the first coat of HydroSeal HF evenly across the entire section, providing a robust waterproofing layer.

12. Applying the Final Topcoat

After the first coat dries completely, we apply a final topcoat of HydroSeal HF, completing the Armtec HyperFlex system with a UV-stable, weather-resistant finish.

Why Flat Concrete Roof Waterproofing Matters in South Africa

South Africa’s climate, with heavy rainfall and intense UV exposure, poses significant challenges for flat concrete roofs. Without proper waterproofing, water pooling can exploit cracks, joints, and poorly sealed outlets, leading to leaks that damage interiors, equipment, and inventory.

In areas, where heavy rains are common, flat roofs are particularly vulnerable. Our Armtec HyperFlex system, with its seamless membrane and UV-stable finish, ensures long-term protection, reducing maintenance costs and preventing structural damage.
