Why Application-Based Waterproofing Matters
Every structure faces different water-related challenges. A basement has constant pressure from groundwater. A roof faces heat, UV exposure, and rainfall. Wet areas face constant moisture cycles. Using one coating for all these conditions rarely works.
Application-based waterproofing helps you select the correct system for the right area. This approach reduces failures, ensures strong bonding, and improves long-term performance. Our waterproofing systems are designed with advanced polymers, cementitious blends, elastomeric coatings, crystalline compounds, and hybrid technologies that deliver stable protection even in tough conditions.
Application Areas – Waterproofing Solutions Built for Demanding Conditions
Below are detailed waterproofing recommendations for all major structural elements. Each section includes a short explanation and suitable product types to provide a clear and practical selection path.
Basement Raft
Basement rafts remain under constant hydrostatic pressure. Without protection, water quickly travels through pores and joints.
Our basement waterproofing products create a seamless barrier that resists pressure, protects reinforcement, and prevents seepage from the lowest structural level.
Preformed Membranes
HDPE (High-Density Polyethylene) is a thermoplastic polymer known for its high strength-to-density ratio, chemical resistance, and durability. It is widely used in construction applications, including waterproofing membranes, due to its impermeability to water and excellent performance in harsh environments.
SBS (Styrene-Butadiene-Styrene) is a thermoplastic elastomer that combines the properties of rubber and plastic, offering excellent flexibility and elongation. It is widely used in modified bitumen membranes, enhancing their durability, crack resistance, and performance under extreme temperature variations.
PVC (Polyvinyl Chloride) membranes are durable, flexible synthetic waterproofing materials known for their excellent resistance to UV rays, chemicals, and weathering. These membranes are commonly used in roofing and waterproofing applications, offering long-lasting protection and easy installation.
Crystalline Waterproofing
Crystalline waterproofing uses advanced reactive chemicals that penetrate concrete to form insoluble crystals, blocking water pathways and sealing microcracks. This technology enhances durability, providing long-term waterproofing that self-heals minor cracks over time.
Integral Waterproofing
Multichem’s versatile cement mixes modifiers/admixtures are specifically designed to enhance cementitious mixes in order to achieve improved mechanical and chemical characteristics with excellent resistance to oil, water and abrasion. Multiguard IW+, Multiguard IWP, Powershield, etc. are additives that impart full leakage protection to concrete structures.

Frequently Asked Questions (FAQ)
Q1. What is the best water leakage solution for terraces?
Terraces often require flexible membranes such as elastomeric or polyurethane coatings due to temperature movement and standing water.
Q2. How do I waterproof a basement?
Basements need a combination of cementitious coatings, integral waterproofing, and drainage solutions depending on pressure and leakage level.
Q3. Can waterproofing be applied on old structures?
Yes, most systems work on both new and old surfaces with proper cleaning, crack filling, and primer application.
Q4. How long does waterproofing last?
Performance varies based on product type, surface preparation, and environmental conditions, but high-quality systems offer long-term durability.
Q5. Is roof waterproofing different from bathroom waterproofing?
Yes. Roofs need UV-resistant, flexible coatings, while bathrooms require cementitious or polymer coatings that bond well to concrete surfaces.
