Designing tie holes in fair-faced concrete

Our recommendations for you on the surface design of exposed concrete walls:

Ensure a void-free edge zone

The flat seal significantly improves the optical quality in the area of the clamping point. A special foam drains excess water and air pockets, ensuring a flawless surface finish around the tie hole.

Choose a shaping plastic cone

Depending on the version selected, the tie hole opening & the respective shadow appearance is demonstrated: flush, set back or shadow gap.

Determine the colour of the closure cones

With our four standard colours or further shades of grey, the clamping points can be closed in a visually appealing way. Coloured closure cones in shades of red, yellow or brown are also available.

Especially for structures with exposed concrete surfaces, optical requirements play a decisive role. MAX FRANK sealing cones impress with their precise shape and quality. Particularly when used in combination with flat gaskets, they ensure homogeneous, durable and aesthetically pleasing concrete surfaces. 

According to the guidelines of the DBV bulletin "Exposed Concrete", the fibre-reinforced concrete sealing cones achieve the exposed concrete classes SB3 or SB4 for special requirements, depending on the design.
