Hauff-Technik MIS200 Membrane Injection System Single House Entry, 200 mm Core Drill

Sealing building service entries through core drillings in waterproof concrete or masonry demands a solution that can withstand pressing water up to 2.5 bar while remaining adaptable for future retrofits. The Hauff-Technik MIS200 Membrane Injection System addresses this challenge with a flexible, injection-based sealing method that ensures a durable, watertight barrier around cables and pipes.

Who is it for

This system is intended for plumbers, electricians, and waterproofing contractors who install service penetrations in below-grade structures, foundation walls, or utility vaults. It suits both new construction and renovation projects where reliable sealing against pressing and non-pressing water is required according to DIN 18533.

Main features

• Membrane injection sealing principle for a permanent, flexible seal.
• Compatible with 200 mm core drillings in waterproof concrete and masonry.
• Withstands water pressure up to 2.5 bar (25 m water column).
• Stainless steel V2A (AISI 304) clamping rings for corrosion resistance.
• High-quality plastic body (PP/PE) resistant to common soil chemicals.
• Allows post-installation and retrofitting of service lines without breaking the seal.
• Internal diameter approx. 150 mm to accommodate Hauff sealing inserts.

Tips

For optimal performance, ensure the core drilling is clean and dry before installation. Use the appropriate Hauff sealing insert for the number and size of service lines. The membrane injection allows for later addition or replacement of cables without compromising the seal.
