| Comparison Dimension | XPS Waterproof Backing Board | Cement Waterproof Backing Board |
| Waterproof & Moisture Resistance | Closed-cell structure, 100% moisture-proof, no water absorption or expansion. It can maintain stable performance in humid environments for a long time without mold or rot. | Requires additional waterproofing treatment. The cement material itself is prone to water absorption, which may lead to mold growth and structural damage over time if not properly treated. |
| Weight & Installation | Lightweight, easy to carry and cut. A single person can complete the installation operation, which greatly saves labor costs and shortens the construction period. | Heavy and bulky, requiring multiple people to cooperate during transportation and installation. Cutting is difficult and requires professional tools, which increases the difficulty and cost of construction. |
| Load-bearing & Durability | High rigidity, strong compression and impact resistance, not easy to crack or deform. It has excellent weather resistance and can maintain stable performance in harsh environments such as high temperature, low temperature and humidity. | Ultra-high load-bearing capacity, but brittle and easy to crack if subjected to impact during construction or use. It is also prone to aging and chalking when exposed to the outdoor environment for a long time. |
| Construction Cost | Higher efficiency in installation, lower labor costs, and no need for additional waterproofing materials, so the overall construction cost is more economical. | Longer construction cycle, higher labor costs, and additional investment in waterproofing materials and processes, resulting in higher overall construction costs. |
| Applicable Scenarios | Suitable for all-scene waterproof projects, including wall cladding, flooring, roofing, bathrooms, basements and other indoor and outdoor construction scenarios. | Only suitable for ultra-heavy load scenarios, such as industrial floors, outdoor high-load ground and other special construction projects that do not require frequent maintenance. |
Why Moisture-Resistant XPS Backing Boards Are Suitable for Most Projects
No Additional Waterproofing Required - Save Time and Money
As a professional supplier of XPS waterproof backboards, Longer is well aware that for most construction projects, time and cost control are of paramount importance. Unlike cement backboards that require additional waterproof coatings and membrane applications, our moisture-proof XPS backboards, with their closed-cell extruded structure, inherently possess waterproof properties. From the moment of installation, they form a reliable waterproof barrier, eliminating the need for complex additional waterproofing procedures. This not only reduces the construction period by an average of 30% but also saves on waterproofing materials and labor costs, helping you maximize the project's benefits.
Long-lasting, not moldy or rotten.
One of the most troublesome problems in construction projects is the mold and rot of building materials caused by dampness, which not only affects the appearance of the project but also reduces the structural safety and service life. Our moisture-proof XPS backboard has completely solved this problem. Its closed-cell structure does not absorb water at all, and it is not easy to breed mold and bacteria even in long-term damp environments such as bathrooms and basements. After years of use, it can still maintain its original performance and appearance, eliminating the trouble and cost of later maintenance and replacement. This is an advantage that no matter how perfect the additional waterproof treatment of cement backboards is, it cannot compare with.
When to choose cement backer board instead of XPS waterproof backer board?
High-load-bearing scenarios, such as the floors of industrial plants
Although our XPS waterproof backboard has excellent load-bearing capacity, it still cannot match the cement backboard in scenarios with extremely high load requirements. For instance, in industrial plants and warehouses where heavy equipment and large amounts of goods need to be supported, the cement backboard would be a more suitable choice. Its extremely high load-bearing capacity can meet the special demands of such projects and ensure the stability and safety of the ground structure.
Extreme high-temperature environment
In extremely high-temperature environments (such as areas near high-temperature equipment in industrial workshops), the high-temperature resistance of XPS waterproof backboards will be somewhat affected. In such cases, cement backboards with better high-temperature resistance are more suitable. They can maintain structural stability in high-temperature conditions and prevent deformation and damage caused by high temperatures. However, it should be noted that even when choosing cement backboards in such scenarios, additional waterproofing treatment must be done to prevent damage from moisture.
Longer XPS waterproof backboard: The better choice for 90% of construction projects
How does our XPS backboard solve the limitations of cement backboards?
After years of research and development, Longer's XPS waterproof backboard has comprehensively addressed the pain points of cement backboards in practical applications. In response to the need for additional waterproofing of cement backboards, our XPS backboard, with its advanced extruded closed-cell technology, achieves 100% waterproof performance, eliminating the need for additional waterproofing measures. Regarding the heavy weight and difficult installation of cement backboards, our XPS backboard is lightweight and easy to cut, significantly improving construction efficiency and reducing labor costs. In addition, to address the issue of mold and rot in cement backboards, our XPS backboard is moisture-proof and mold-resistant, with a long service life and no need for frequent maintenance.
Bulk wholesale solutions for large-scale replacement
We understand that many construction companies and purchasers are seeking more economical and reliable alternatives to cement backboards for large-scale projects to replace traditional cement waterproof backboards. Therefore, Longer offers flexible bulk wholesale solutions for XPS waterproof backboards. No matter how large your project is, we can provide sufficient supplies and competitive wholesale prices.
