Waterproofing & Roofing

Waterproofing failures are among the most costly and disruptive building defects, and the weak points are predictable: penetrations, terminations, movement joints, and transitions between membrane systems and rigid substrates. Conventional hot-applied bituminous systems, cementitious coatings, and polyurethane liquid membranes each carry process limitations — fire risk, substrate moisture sensitivity, isocyanate exposure, or VOC emissions — that silyl-modified polymer alternatives can address.

MS polymer sealants and liquid membrane binders provide crack-bridging flexibility, seamless application, zero-VOC chemistry, and primerless adhesion to concrete, metal, and existing membrane surfaces. The technology has been validated as a waterproofing membrane binder by resin producers and is commercially deployed in balcony, terrace, and wet-room applications. For detail sealing — the penetrations, upstands, and terminations that are the source of most waterproofing failures — MS polymer sealants offer compatibility with bituminous, single-ply, and liquid-applied membrane systems without the solvent attack or adhesion failures that occur with mismatched sealant chemistry.

Silantek’s waterproofing product range includes roof penetration and flashing sealants, STP-based liquid waterproofing membrane binders for balconies and terraces, and below-grade joint sealants for foundation and basement applications with hydrostatic pressure resistance and damp-substrate adhesion capability.
