Formwork cone DK-SK

Overview
Reliable sealing solution for tie points in cast concrete walls. The PERI DK and SK systems close tie point passages using concrete cones fixed with a specially developed sealing adhesive, suitable for exposed concrete and security applications.

DK sealing cone system

• waterproof
• gas impermeable
• fire-resistant
• soundproof
• suitable for architectural/exposed concrete

SK tie cone system

• waterproof
• gas impermeable
• fire-resistant (F90 in certified variants)
• soundproof
• suitable for security areas and architectural concrete

Performance
Designed and tested for guaranteed leak-tightness. Systems are waterproof and gas-impermeable, fire-resistant, soundproof and diffusion-proof. Certain variants are approved for use in drinking water containers and for wall thicknesses up to 60 cm.

Availability
Cones and spacer tubes are supplied for a range of tie diameters; variants and accessories are available to integrate with common formwork systems.
