COLD-APPLIED SINGLE-COMPONENT WATERPROOFING FOR CONCRETE AND MASONRY
HYDRALASTIC 836 is a cold-applied, single-component waterproofing membrane designed to protect concrete, wood, and metal surfaces from water intrusion in both above- and below-grade applications. This solvent-free, VOC-compliant material cures to form a seamless, flexible barrier that adheres strongly to most substrates—even green concrete—without shrinking or slumping.
Ideal for plaza decks, planters, parapets, foundations, and split-slab construction, HYDRALASTIC 836 delivers exceptional durability, elasticity, and chemical stability while remaining easy to apply with a roller, trowel, or squeegee. It can be reinforced with W. R. MEADOWS REINFORCING FABRIC HCR for high-build systems and is compatible with MEL-DRAIN™ and PC2R PROTECTION COURSE.
