KOESTER Bikuthan 2K

KOESTER Bikuthan 2K is a two-component bituminous compound (KMB) with added polystyrene granules. This flexible, solvent-free compound effectively bridges cracks. Bikuthan 2K is designed for long-lasting waterproofing of foundations, basement walls, and foundation slabs. It offers excellent adhesion to both dry and slightly damp substrates.

Features of Bikuthan 2K:

• Waterproof
• Flexible
• Bridges substrate cracks
• Resistant to groundwater and various underground corrosive substances
• Easy to apply and control layer thickness
• Rain-resistant shortly after application
• Complies with the PN EN-15814:2012 standard

Applications of Bikuthan 2K:

• Primarily used for durable waterproofing of external basement walls, foundations, foundation slabs, etc.
• Suitable for waterproofing under floorings on terraces and balconies
• Can also be used for adhering insulation boards

KOESTER Bikuthan 2K meets DIN 18195 standards, providing durable protection against ground moisture and non-pressurized water, as well as standing rainwater and pressurized water on ceilings and in wet rooms.

What is Waterproofing?

Waterproofing, also known as moisture protection, involves securing a structure against the damaging effects of water. Waterproofing products are classified based on the binding agent:

• Bitumen and tar-based (an older method being phased out): Offers high water resistance but has poor interlayer adhesion and health risks.
• Synthetic resin-based (modern products): Primarily effective indoors, suitable for residential use but not for large water tanks.
• Mineral-polymer waterproofing compounds: These, also known as sealing or insulating slurries, avoid the drawbacks of other types and are ideal for waterproofing walls, plinths, pools, balconies, terraces, roofs, and high-humidity rooms.
• Multi-component reactive resin-based (latest binders): These include polyurethane and epoxy resins, providing high adhesion and complete waterproofing.

Consumption:

• Approx. 4.0 - 5.0 L/m²
