Waterproofing can be categorized into 3 major application types. 1) Sheet Membrane, 2) Liquid Applied Membrane, and 3) Sprayed Applied Waterproofing Membrane (by machine).
The main difference would be the application method. Each has its own advantages. Liquid applied membrane can take any profile of the concrete surface, while waterproofing membrane sheet is consistent in terms of membrane thickness and characteristics. Aquaflex Roof, Plastimul PU and Purtop Easy are examples of Liquid Applied Membrane. Mapethene TA, Mapethene HT SP, Mapeproof AL AP and Spider P are examples of Sheet Membrane.
Mapei has complete solutions portfolio for waterproofing underground structures. Mapeproof AL AP, Mapethene HT SP and Mapelastic Foundation are some products developed for underground waterproofing. First, we need to understand the water table and type of construction for the project before a right product is being proposed.
