About Construction Waterproofing
Construction waterproofing refers to the materials and systems used in the process of making a building resistant to water infiltration. Construction waterproofing helps maintain the integrity of the structure and the prevention of damage due to water intrusion. Construction waterproofing is generally considered to be distinct from roofing, and typically refers to below-grade or at-grade waterproofing that specifically protects parts of a building that are below the level of the roof, such as exterior walls, basements, foundations, and retaining walls.
Some Types of Construction Waterproofing Products
- Sheet Membranes: These are large, pre-formed sheets of waterproof material, often made from rubberized asphalt or modified bitumen. These sheets are applied to the outside of the walls or foundation and joined (or “seamed”) together much like a single-ply roof membrane to provide a continuous waterproof barrier.
- Liquid Membranes: These are fluid-applied coatings that cure to form a seamless (typically rubbery) membrane. They can be sprayed, rolled, or troweled onto the surface and are usually very effective when it comes to filling in cracks and gaps.
- Cementitious Waterproofing: This type of waterproofing involves the application of a cement-based mixture to the surface. It’s often used for its ease of application, textured appearance, and strong adhesion to concrete and masonry surfaces. Stucco, often modified with waterproofing additives, is an example of cementitious waterproofing.
- Bentonite Waterproofing: Bentonite is a type of clay that swells when it comes into contact with water, creating a dense, impenetrable barrier. It is often used in sheet form (think of large envelopes filled with bentonite particles) or as part of a composite system with other materials, such as adhesives, which hold the clay in place.
- Crystalline Waterproofing: This method involves applying a crystalline compound to a concrete surface. When water contacts the compound, it causes a chemical reaction that forms crystals, which block the pores and capillaries in the concrete.
Important Considerations Before Buying Waterproofing Products
- Type of Structure and Conditions: Determine the specific needs of your structure. Factors like soil conditions, typical groundwater levels, potential hydrostatic pressure due to soil saturation, and the type of foundation should be taken into account.
- Service Life: Look for products known for their durability and long-term performance. The cost of re-applying waterproofing can be a lot more than you might think, so doing it right the first time is a really good idea.
- Ease of Application: Many waterproofing products require specialized training and equipment to install properly. Think about whether you want to apply the product yourself or hire a professional installer.
- Compatibility with Other Building Materials: Some waterproofing products are not compatible with some substrates. Always check for compatibility before buying a waterproofing product.
- Environmental Impact: Some waterproofing products may contain harmful chemicals. You may want to look into this before applying something to your basement walls.
Importance of Choosing a Good Construction Waterproofing Manufacturer
- Quality Assurance: Reputable manufacturers are more likely to have strict manufacturing protocols that result in high-quality, reliable products. This is particularly important with chemical products like many waterproofing materials that need to be precisely and carefully formulated and mixed. Poor-quality materials can easily lead to material failure and expensive repairs.
- Technical Support: Reputable manufacturers will have technical departments that can provide technical support and guidance to help you through your project and answer any questions you might have.
- Compliance with Codes and Standards: Established manufacturers take care to meet industry standards and comply with the regulations that govern their industry. They will generally have systems in place to ensure that their products are safe and effective.
- Reputation and Reviews: This may go without saying, but reputable manufacturers will have a good reputation and positive reviews that will help you feel comfortable buying from them.
Conclusion
Construction waterproofing is often an important part of the building envelope. It can be necessary in order to properly protect the structural integrity of a building. Selecting a reputable manufacturer is usually the first step toward ensuring the quality of your waterproofing system.
