Sikalastic® HLM 5000 GC
Short Description
Sikalastic® HLM 5000 GC is a high-performance, cold-applied, elastomeric waterproofing membrane designed for below-grade and between-slab applications. This one-component, bitumen-modified polyurethane coating provides seamless waterproofing, crack-bridging properties, and resistance to chemicals and extreme weather conditions. Ideal for foundations, parking garages, plaza decks, balconies, and planters.
Sikalastic® HLM 5000 GC is a liquid-applied, moisture-curing waterproofing membrane engineered to provide seamless protection for below-grade structures and between-slab applications. Formulated with bitumen-modified polyurethane, it delivers superior elasticity, crack-bridging capabilities, and long-term durability, making it ideal for high-performance waterproofing solutions.
This cold-applied, fully adhered system is designed for concrete, plywood, foundation walls, and split slabs. It offers high chemical resistance, wide service temperature tolerance (-40°F to 120°F), and seamless application without the need for hot-melt equipment.
