Brick:
* Clay Brick: Traditional clay bricks are porous. They absorb water, which can lead to issues like efflorescence (white powdery deposits) and frost damage.
* Concrete Brick: Concrete bricks are less porous than clay bricks, but still not entirely non-porous. They can be treated with sealants to further reduce porosity.
* Glass Brick: Glass bricks are completely non-porous, making them ideal for areas where moisture is a concern. However, they are more expensive than traditional brick and can be difficult to work with.
Mortar:
* Traditional Mortar: Traditional mortar is made from cement, sand, and water. It is porous, allowing water to pass through it.
* Epoxy Mortar: Epoxy mortar is non-porous and extremely strong. It is often used in areas where water resistance is essential, like showers and swimming pools.
* Polymer Mortar: Polymer mortar is less porous than traditional mortar and can be used in a variety of applications, but it's not entirely non-porous.
Solutions for Reducing Porosity:
* Sealants: Applying a sealant to the brick and mortar can significantly reduce water absorption. There are various sealants available, each with its own level of protection.
* Waterproofing Membranes: These are applied to the wall before the brick and mortar are installed, creating a barrier that prevents water penetration.
Conclusion:
While achieving complete non-porosity in brick and mortar is challenging, there are options available to greatly reduce porosity. The best choice will depend on your specific needs and budget. For example, if you need a highly water-resistant solution for a shower, using glass bricks with epoxy mortar would be ideal.
Always consult with a qualified building professional for advice on the best materials and techniques for your project.
