Vandex Crystalline Waterproofing Solutions

Completely Constricts Waterflow

Allows Water Vapour Pass

Ccertified ISO 9001 & 14001

In 1943, the Danish chemist Lauritz Jensen patented a groundbreaking capillary active concrete waterproofing method. He founded his first company in Denmark in 1946, naming it VANDEX ("water out"). This innovative approach quickly gained traction in the Scandinavian market and subsequently expanded into Europe.

During the 1950s and 1960s, Vandex expanded globally through subsidiaries, licensing, and distributorships. In 1979, Swiss interests acquired the Vandex Group, and Vandex International Ltd was established to oversee its international activities. The 1990s saw further expansion into Eastern Europe, Asia, and South America. Today, Vandex is recognized as a leading brand in over 70 countries worldwide.

With over 65 years of successfully completed waterproofing projects, Vandex has established itself not only as a technology innovator but also as a reliable partner dedicated to long-term customer relationships through responsible marketing and robust technical support.

With an impressive track record of successfully completed waterproofing jobs ranging from preventive work in new construction to complex troubleshooting in existing structures carried out over a period of more than 65 years, the Vandex Group has gained worldwide recognition not only as a technology inventor but also as a reliable partner which aims at long-term, close customer relationships through responsible marketing and strong technical support.
Vandex gives priority to responding to customer requirements concerning products or systems and to developing products and services which provide attractive customer benefits. Vandex’s technical services for users, designers and applicators assure a high degree of customer satisfaction.

How it Works:

STEP 1

Here, we have a portion of a dry concrete wall that contains moisture and naturally occurring free lime.

STEP 2

The concrete wall was exposed to water as a result of rain or any other source. The capillaries have been forcibly accessed by the water.

STEP 3

Vandex crystalline treatment: The reaction between the moisture, free lime, and Vandex chemicals has begun.

STEP 4

Now the concrete is waterproof. Vandex permeates the concrete and creates crystals that significantly obstruct the capillaries while yet allowing water vapour to get through.

STEP 5

There are still Vandex crystals in the concrete, ready to revive upon contact with water. The strong concrete has now been extensively pierced by the crystals.

VANDEX SUPER

VANDEX SUPER is a ready-mixed cementitious in-depth waterproofer, ideal for protecting concrete from salt water, wastewater, corrosive groundwater, and certain chemical solutions. Thoroughly tested for use with drinking water, it reacts with free lime and moisture in concrete to form insoluble crystalline complexes, sealing capillaries and tiny shrinkage cracks.

Applications:

Substrates: Concrete
Drinking water structures
Backfilled structural elements, foundations, slabs, retaining walls, construction joints, sewage treatment plants, swimming pools, etc.
Active or passive waterproofing and protection against water and moisture.

VANDEX AM 10

VANDEX AM 10 is a crystalline waterproofing admixture powder that interacts with concrete’s capillary pore structures to create a permanent waterproofing system. Suitable for both above and below-grade applications, it forms insoluble crystalline complexes that seal capillaries and tiny shrinkage cracks.

Applications:

Waste treatment facilities
Foundations and basements
Marine structures
Precast concrete
Tunnels and subways
Dams and water reservoirs
Manholes
Underground vaults
Parking structures
Swimming pools
Water containment structures

Features & Benefits:

Limits or eliminates water penetration
Waterproofs against hydrostatic pressure
No negative impact on compressive strength or setting time with Portland cement
Simple to use, powdered material
Minimal effect on working time, enhances flexibility
Greatly enhances chemical resistance
Cost-effective compared to other approaches

VANDEX UNI
MORTAR 1

VANDEX UNI MORTAR 1 is a cementitious, ready-mixed mortar designed for waterproofing and repairing applications. Its composition includes cement, quartz with a graded grain size distribution, and specific additives, making it an excellent waterproofing solution. Once hardened, it is both durable and frost-resistant, while still allowing vapor permeability.

Applications:

Substrates: Concrete, masonry, and natural stonework
Waterproofing: Effective protection against water and moisture penetration
Leveling & Reprofiling: Can be applied both horizontally & vertically for surface smoothing & restoration
Fillets for Wall-Floor Junctions: Provides a seamless transition at the junctions
Structural Elements: Suitable for foundations, slabs, retaining walls, and other critical structural components
Drinking Water Structures: Safe for use in potable water applications

Features and Benefits:

Durability: Offers long-lasting protection and resistance to harsh conditions
Frost Resistance: Maintains integrity in freezing temperatures
Vapor Permeability: Allows the structure to “breathe” while preventing water ingress
