Living in the Philippines means dealing with a tropical climate that brings a lot of rain, especially during the monsoon season. Ensuring that your home is properly waterproofed is essential to prevent damage from water infiltration—things that can compromise the structural integrity of your property and lead to costly repairs. 


Preparing for the rainy season is vital for preserving your home’s structure and, most important of all, will keep the indoors safe and dry. In this article, we will guide you through the importance of waterproofing, the science behind waterproof cement and membranes, and a step-by-step process on how to use these materials effectively.


The Importance of Waterproofing Your Home

The Philippines is prone to heavy rainfall and typhoons, which can cause significant water damage to homes. Waterproofing is crucial to protect your property from water infiltration that can lead to mold growth, wood rot, and concrete deterioration. Proper waterproofing not only enhances the durability of your home but also ensures the safety and health of its occupants.


The Science Behind Waterproof Cement and Membranes

Waterproof cement and membranes are designed to create a barrier that prevents water from penetrating concrete structures. Understanding the science behind waterproof cement and membranes can help increase the lifespan of a structure, making them less susceptible to the deteriorating effects of water.


Waterproof Cement

This type of cement is formulated with additives that repel water. These additives create a hydrophobic surface within the concrete, reducing its porosity and preventing water from seeping through. When water contacts the surface, it beads up and rolls off instead of being absorbed.


Waterproof Membranes

These are thin layers of waterproof material that can be applied to surfaces to create a continuous barrier against water. There are various types of waterproof membranes, including liquid-applied membranes, sheet membranes, and spray-on membranes. These membranes work by forming a seamless, impermeable layer that water cannot pass through, effectively protecting the underlying structure.


Step-by-Step Guide: Using Waterproof Cement and Membranes

Knowing the step-by-step guide for using waterproof cement and membranes is crucial to ensure proper application, prevent water damage, enhance structural durability, and extend the lifespan of buildings and structures by effectively creating watertight seals and barriers.


Using Waterproof Cement

  • Preparation: Clean the surface thoroughly to remove any dirt, oil, or loose particles. Repair any cracks or holes with a suitable filler.
  • Mixing: Follow the manufacturer’s instructions to mix the waterproof cement. Typically, you will need to add water to the dry mix and stir until you achieve a smooth, lump-free consistency.
  • Application: Apply the waterproof cement using a trowel, starting from one corner and working your way across the surface. Ensure an even layer is spread to cover the entire area.
  • Curing: Allow the cement to cure according to the manufacturer’s instructions. Curing time may vary depending on the product used.


Applying Waterproof Membranes

  • Surface Preparation: Clean and dry the surface thoroughly. Any moisture or dust can affect the adhesion of the membrane.
  • Priming: Some membranes require a primer to be applied first. Check the product guidelines and apply the primer if necessary.
  • Application: If using a sheet membrane, cut it to size and press it firmly onto the surface, ensuring there are no air bubbles. For liquid-applied membranes, use a brush or roller to apply an even coat. For spray-on membranes, follow the equipment guidelines for application.
  • Sealing Joints: Pay special attention to corners, joints, and edges. These areas are more susceptible to water infiltration. Use additional membrane material or sealant to reinforce these vulnerable spots.
  • Drying/Curing: Allow the membrane to dry or cure as per the manufacturer’s instructions before exposing it to water.


Choosing the Right Concrete Mixture

For different parts of the house, infrastructure projects like roads, bridges, public spaces, and large buildings, the concrete mixture varies to meet specific requirements:

  • Foundations and basements: Use a mix with high waterproofing properties, typically with additives like silica fume.
  • Driveways and walkways: Opt for a mix that balances strength and durability, often with a lower water-cement ratio.
  • Bridges and public structures: High-performance concrete mixes with added fibers and admixtures to enhance strength and durability against environmental stressors.


Keeping Homes Safe and Dry All Year Round

Waterproofing your home and other structures is essential in the Philippines’ wet climate. By understanding and applying the right materials and techniques, you can protect your property from water damage, ensuring its longevity and safety for years to come.
