PETER GREVEN – Your partner for construction

Within the construction industry many building materials are made hydrophobic to secure a long-term protection against harmful weather influence.

During hydrophobization, the surface is coated throughout the entire cross-section so that the protection of the building material is guaranteed for many years. Peter Greven outdoor weathering test series of building material treated with our hydrophobing agents were carried out to prove the long-term effectiveness.

Metallic soaps and alkaline soaps are very suitable hydrophobing agents. Metallic soaps are among the non-reactive hydrophobing agents for their natural hydrophobing effect, while alkaline soaps are effective through reaction with mineral components of the building material. Therefore, they are also known as reactive hydrophobing agents.

Combination products complete our construction product portfolio and combine the advantages of non-reactive and reactive hydrophobing agents.

In addition to the product categories mentioned above we also offer a range of selected dispersions suitable for special applications within the construction industry.

Application areas within the construction industry

/

Plaster

Basic Plaster

Basic plasters are common building materials. They need hydrophobization but the requirements for the hydrophobing agent used are less complex compared to other plaster types. It is particularly important that the plasters ability to sustain the natural moisture balance is not affected by the hydrophobing agent.  

Our metallic soaps are very suitable for the hydrophobization of basic plasters as they offer good hydrophobing properties while they don’t exhibit a negative impact on the natural moisture balance.
 

Finishing Plaster

Finishing plaster needs very good hydrophobization because it is directly exposed to weathering as it forms the top layer. Additionally, the hydrophobing agent is required not to impact the plasters surface structure.

Dependent on the respective customer requirements, our metallic soaps as well as our alkaline soaps or combination products can be used as hydrophobing agents.
 

Restoration Plaster

Restoration plasters are indispensable building materials for restoration projects. Their requirements for hydrophobing agents are very high since water needs to evaporate from the damaged spots while, at the same time, the intrusion of new water must be prevented.

In this application our metallic soaps and combination products are particularly suitable as they offer the necessary valve effect without affecting the air voids of the system.

Mortar

Adhesive and Reinforcing Mortar

Adhesive and reinforcing mortars are used as foundation for the majority of multi-layer plaster systems. Good hydrophobization is required as they form a stable intermediate layer between ground and plaster.

Our alkaline soaps and combination products offer the best protection for adhesive and reinforcing mortar.
 

Grout

Grout is commonly used as a foundation for tiles or paving stones. In addition to good stability it needs to provide a smooth surface. Hydrophobing agents are needed to secure those properties by preventing the grout from swelling caused by penetration of water.

The alkaline soaps and combination products range has also proved very successful for grout applications.

Adhesive

Tile or reinforcement adhesives, for example, are important basic materials for construction industry and bring up special requirements for their hydrophobing agents. They require them to provide a good wettability of the surface while simultaneously offering a sufficient hydrophobing effect.

According to these requirements, our alkaline soaps and combination products are suitable for adhesive hydrophobization.

Special Applications

External Thermal Insulation Composite System (ETICS)

External thermal insulation composite systems are thermal insulation systems consisting of multiple layers. Due to the different materials used in this system a good hydrophobization is required to secure the longevity.

Our alkaline soaps as well as our combination products offer ideal properties for the use in ETICS.
 

Concrete / Cement / Screed

With concrete, cement and screed, mixing often takes place in liquid form. Therefore, the requirements for the hydrophobing agents often vary from the ones for other building materials. A hydrophobing agent that is also liquid is almost indispensable as it has less influence on the capillary system and viscosity.

In addition to the product categories metallic soaps, alkaline soaps and combination products we also offer dispersions. These specialty products are particularly suitable for the extraordinary requirements in these applications.
