Modified
Applied as a second coat, Xypex Modified chemically reinforces Xypex Concentrate where two coats are required and produces a harder finish. Where damp proofing is required, a single coat of Modified may be used as an alternative to a spray/tar emulsion.
Advantages of Xypex
- Becomes an integral part of the substrate
- Resists extreme hydrostatic pressure
- Can seal static hairline cracks up to 0.5 mm
- Highly resistant to aggressive chemicals
- Can be applied to the positive or the negative side of
the concrete surface - Does not require a dry surface
- Non-toxic / no VOCs
- Is Permanent solution requiring no further maintenance
- Less costly to apply than most other methods
- Extends the service life of concrete
- No costly surface priming or leveling prior to application
- Does not require sealing, lapping and finishing of seams at
corners, edges or between membranes - Does not require protection during backfilling or during
placement of steel, wire mesh or other materials - Cannot puncture, tear or come apart at the seams
- Allows concrete to breathe

General Resources
Ikaalisten Vesitorni Water Tower Rehabilitation
The rehabilitation and waterproofing project for the Ikaalisten Vesitorni Water Tower in Finland required materials certified for potable water. Its shape also presented unique challenges making it difficult to install scaffolding and access both the inner and outer basins, so traditional waterproofing methods were not suitable applications.
Covenant University
In 2018, Covenant University in Lagos, Nigeria, undertook a significant waterproofing and concrete protection project involving two mathematics halls and a hall of residence. The project utilized Xypex Admix, Xypex Concentrate, and Xypex Modified to ensure the highest level of durability and integrity in the treated areas.
Flensburg Navy Barrack Conversion
In the picturesque northernmost city of Flensburg, Germany an ambitious project was undertaken to transform a section of an old German navy base into a new focal point for tourism, leveraging its stunning views of the Baltic Sea harbor and the quaint old town center.
MDA Levis - Seniors’ Residence Foundation Waterproofing
In the strategic rejuvenation of the MDA Levis Seniors’ Residence, the team faced a significant challenge: a compromised raft slab and basement walls due to the failure of an existing membrane waterproofing system. Positioned 4 feet within the water table and enduring a constant hydrostatic pressure of 1.7 psi, the need for a definitive and enduring waterproofing solution was paramount.

Solar Power Plants - Transformer stations, Fire water tanks
In Hungary, as in other countries around the world, the harnessing of solar energy for direct energy production is increasingly becoming popular. Recent years have seen the construction of several small and notably more powerful solar power plants. These solar parks aim to further decrease Hungary's reliance on fossil fuels and reduce the emissions of harmful substances.
Projects Using This Product
Harry Tracy Water Treatment Plant
The 11 million gallon reservoir is a cast-in-place double-walled construction concrete tank with spiral bound shotcrete exterior. Xypex products were chosen to waterproof and protect the concrete on the inside of this tank – approximately 100,000 sq. ft.
John G. Shedd Aquarium
Xypex products were used at the prestigious Shedd Aquarium in Chicago, a project that has become well known because of the complexity of its construction and because it includes the world’s largest enclosed artificial ocean.
Funkers Crossing
As part of flood repairs to New England Highway just outside of Stanthorpe, new culverts were constructed as part of the road upgrade for improved flood prevention.
One & Only Resort Pool
Xypex products were specified to waterproof and protect various areas of this One & Only Resort project, including two undersea tunnels, lift shafts, health spa pools, day water tank, penthouse swimming pool and the main one-million litre swimming pool.
Pearson International Airport
Xypex products were chosen for the repair and restoration of the glycol (de-icing) containment tanks. This project included the repair of cracks, pressure washing all surfaces for removal of existing coatings and the application of Xypex Concentrate and Modified to 40,000 sq. ft. of tank walls and floors.
Podlesice Animal Barn
Xypex provided complete waterproofing of this newly constructed floor and sewage pit in a piggery on a private farm. The old deteriorated floor was removed, newly constructed with gutters/ducts and treated with a two-coat application of Xypex Concentrate and Modified.
