Peneseal Pro

Advanced Concrete Protection and Crack Sealing

A spray-applied liquid sealer for durable concrete protection. PENESEAL PRO penetrates concrete surfaces, forming a long-lasting sub-surface gel barrier that permanently seals hairline cracks and blocks moisture penetration. This treatment maintains the concrete’s breathability while protecting against water ingress, chemical exposure, and environmental wear. Applied to exposed slabs, parking decks, rooftops, and bridges, PENESEAL PRO enhances structural integrity without altering the surface appearance. Its ability to self-heal minor cracks over time makes it an excellent choice for sustainable and low-maintenance waterproofing solutions.

Key Features of PENESEAL PRO
