There are several types of waterproofing systems available, each with its own advantages and disadvantages. Here are some of the most common types:

1. Sheet Membrane Waterproofing: This type of waterproofing involves the use of a thin, flexible sheet that is applied to the surface to be waterproofed. It is commonly used for roofs, decks, and balconies.

2. Liquid Membrane Waterproofing: This type of waterproofing involves the use of a liquid coating that is applied to the surface to be waterproofed. It is commonly used for roofs, walls, and foundations.

3. Cementitious Waterproofing: This type of waterproofing involves the use of a cement-based coating that is applied to the surface to be waterproofed. It is commonly used for concrete structures such as basements and swimming pools.

4. Bituminous Waterproofing: This type of waterproofing involves the use of a bitumen-based coating that is applied to the surface to be waterproofed. It is commonly used for roofs and foundations.

5. Polyurethane Liquid Membrane Waterproofing: This type of waterproofing involves the use of a polyurethane-based liquid coating that is applied to the surface to be waterproofed. It is commonly used for roofs, walls, and foundations.

6. Polymer-modified Cementitious Waterproofing: This type of waterproofing involves the use of a cement-based coating that has been modified with polymers to improve its performance. It is commonly used for concrete structures such as basements and swimming pools.

These are just a few examples of the many types of waterproofing systems available. The choice of system will depend on various factors such as the type of structure being waterproofed, the location, and the budget.
