As experts in the field, we at Flexi Tech Contracting know that effective protection begins with understanding the specific vulnerabilities of your building. Commercial waterproofing is not a one-size-fits-all solution; it requires a tailored approach using specialized materials for different surfaces like the foundation, deck, and concrete areas. By exploring the main types of systems available, we can help ensure your building remains structurally sound and dry for years to come.
What Are the Different Types of Commercial Waterproofing?
Liquid-Applied Membrane Systems
Liquid-applied membranes are highly versatile and cure into a seamless, rubber-like elastomeric coating. We often utilize these systems for complex surfaces or areas where a continuous, monolithic barrier is essential, such as parking decks or large pedestrian areas. This type of coating maintains exceptional flexibility, accommodating the natural movement of the building structure without cracking, which is a critical feature for long-term waterproofing integrity.
Sheet-Applied Membrane Systems
Sheet-applied membranes, including modified bitumen, PVC, or EPDM rubber, are factory-made barriers that are rolled onto the substrate. We apply these pre-formed sheets for robust below-grade foundation waterproofing and on large, flat surfaces like commercial rooftops. Their uniform thickness and high puncture resistance offer superior protection against hydrostatic pressure and aggressive soil conditions.
Cementitious Waterproofing Coatings
Cementitious waterproofing uses cement-based compounds that are mixed with acrylic additives or water and then troweled or brushed onto the concrete surface. This method is effective for internal wet areas and subterranean walls where a rigid, durable barrier is needed against dampness and minor hydrostatic pressure. Because it chemically bonds with the concrete, it becomes an integral part of the structure, providing reliable, cost-effective defense against moisture migration.
Crystalline Waterproofing Admixtures
Crystalline waterproofing is a unique hydrophilic technology that is added directly to the concrete mix during construction or applied as a slurry to existing concrete. We prefer this method for commercial foundation waterproofing. This process seals the concrete itself, effectively making the entire mass waterproof and providing 'self-healing' properties against small cracks.
