NEXLER BITFLEX 1K: polymer-modified thick waterproofing coating, 20 kg, waterproofing system component

Waterproofing helps preserve a building’s function in areas hidden below ground or beneath finishes. Sealing compounds carry protection across surfaces with different shapes. Their form is particularly practical at corners and service penetrations where a precise fit is needed.

An applied material can form a continuous layer across changes of plane and properly prepared details. There is no need to cut a separate sheet for each short section of foundation wall. The compound covers the planned area, while suitable accessories seal pipe penetrations and joints. This is especially useful in refurbishment where the existing substrate is complex. The chosen method follows the building geometry while maintaining the required layer thickness and continuity. Combining a compound with a collar is particularly useful around services, protecting the wall penetration without leaving a gap in the coating.

Polymer-modified bituminous compounds can form a flexible coating that bridges cracks within the manufacturer’s stated limits. This helps maintain watertightness during small substrate changes allowed for by the system. BITFLEX 1K PMBC, also known as KMB, is one example. A flexible barrier complements the rigid foundation structure and helps treat difficult connections. It prevents water entering the protected part of the element and supports the durability of subsequent layers.

Ready-to-use one-component compounds reduce mixing preparation. Products approved for trowel or spray application allow the working method to suit the area. Small sections permit close attention to details, while larger surfaces suit a repeatable application process. Selected products may also be used on slightly damp substrates as specified in their technical data sheet. This helps fit waterproofing into actual site conditions while observing the necessary drying intervals.

Waterproofing foundations or basement walls matters to future indoor use, even though it will no longer be visible. It helps protect the substrate and finishes from moisture penetration. Suitable compounds can also work alongside thermal insulation; solvent-free products intended for this contact are compatible with polystyrene. Protection is matched to water exposure, from ground moisture to more demanding conditions. The solution therefore has a specific function suited to its location in the building.
