Best in class – Quality & Performance

Our products are engineered and manufactured to the highest quality standards (in primarily Germany/Switzerland) and have been successfully used worldwide with zero product failures.

Independently Tested

Our products are independently tested with exceptional results (German Railway, Swedish Vattenfall, Kiwa accredited testing laboratory, SKZ accredited testing laboratory etc)

We’re greener

We’re green building certified (LEED, BREEAM, Nordic Swan Ecolabel) and our carbon neutral production facility is solar-powered and uses recycled rainwater to minimize our impact on the environment.

We lead through innovation

We only do Structural Waterproofing and where others are happy with good enough, we keep innovating to make waterproofing better, more durable, easier to install and more sustainable. In 2019 we were named one of Germanys Top 100 most innovative companies for the third time in four years (*BPA Gmbh).

Certified and accredited

We’re certified by many of the leading international standards including British, German and US/Canada (ICC-ES).

Over 20 years of excellence in waterproofing

We’ve spent the last two decades helping designers, specifiers and contractors select, design and install the optimal waterproofing for their projects.

Don’t leave yourself exposed when building below ground

Below ground structures can be subjected to many different exposures including varying levels of water exposure due to damp soil, percolating water, open water or water under hydrostatic pressure. This can lead to corrosion of steel reinforcement/structural damage, loss of thermal insulation and ultimately a negative impact on the internal environment due to condensation and mold growth.

 

 

For a design professional, there are certain additional risks that come with the territory when planning the construction of a below ground structure like a basement or tunnel for example. As these types of structures will be fully, or partially exposed to the surrounding soil and groundwater they will need to be designed to withstand a wide range of potential structural and environmental stresses.

If not properly addressed in the design stage, there may be severe long-term consequences affecting the integrity of your structure as a lack of water-tightness, and the following inevitable water ingress will invariably cause physical attack and deterioration of concrete and reinforcements.

For the owner of the building, the consequence will be costly structural repairs, and potential damages to the internal environment due to damp and condensation.

How environmental exposure impacts your structure

Below ground structures can be subjected to many different exposures including varying levels of water exposure due to damp soil, percolating water, open water or water under hydrostatic pressure. This can lead to corrosion of steel reinforcement/structural damage, loss of thermal insulation and ultimately a negative impact on the internal environment due to condensation and mold growth.

 

 

Structural exposure
Ground water

Ground water containing aggressive chemicals (commonly sulphates and chlorides) cause concrete damage (due to sulphate attack) and corrosion of steel reinforcement (due to chloride attack)

 

Structural exposure
Aggressive biological influences

Aggressive biological influences such as fungal or bacterial attack as well as plant growth/roots can damage an insufficient waterproofing barrier, causing harm to indoor finishes, and the contents of a building.

 

Unequal static forces

Unequal static forces due to load, settlement, or uplift cause structural cracking. As does dynamic forces from ground settlement, earthquakes, etc.).

 

Structural exposure
Ground gases

Ground gases such as Methane and Radon are harmful for inhabitants.

 

Structural exposure
Temperature variations

Temperature variations such as frost or heat during summer cause condensation, scaling or cracking of concrete.

 

Reduced service life

These different types of exposure reduce the service life of the entire structure if it is not sufficiently waterproofed.

 

The waterproofing system typically represents only
a small fraction (around 1%) of the total core construction cost

Yes, you can “design out” these potential risks

Remedial activities are both difficult and expensive in terms of access to and treatment of any potential leaks; thus, it is very important that due care and consideration are taken in the design, planning, selection, and installation of the structural waterproofing system.

Keep in mind that a waterproofing system typically represents only a small fraction (around 1%) of the total core construction cost, which means that proper design and selection of high quality waterproofing system can easily save this amount or more by eliminating future maintenance and repair costs over the service life of the structure.

Not to mention eliminating “bad will” and damaged reputations caused by a failure to waterproof.
