HDPE (High-Density Polyethylene) system for basements
The HDPE (High-Density Polyethylene) system for basements is a waterproofing solution that involves the installation of HDPE membranes to prevent water intrusion and moisture damage in below-grade structures.
Advantages
- Waterproofing: HDPE membranes provide a seamless barrier against water infiltration, ensuring dry and protected basement spaces.
- Chemical Resistance: Resistant to chemicals commonly found in soil and groundwater, ensuring stability and longevity of the waterproofing system.
- Durability: HDPE membranes are highly durable, withstanding the pressures and stresses of below-grade environments.
- Flexibility: Adapts to structural movements without cracking or splitting, maintaining waterproofing integrity.
- Ease of Installation: HDPE membranes are lightweight and easy to install, reducing labor costs and construction time.
- Versatility: Suitable for various below-grade structures, including basements, foundations, and retaining walls.
- Longevity: Provides long-lasting protection against water intrusion, minimizing the need for future repairs or maintenance.
PU Injection
PU injection on concrete roof soffit involves injecting polyurethane foam into voids or cracks to repair and reinforce the structure. This process is commonly used to restore the integrity of concrete soffits and prevent further damage.
Advantages
- Seamless Repair: PU injection fills voids and cracks seamlessly, restoring the structural integrity of concrete soffits.
- Waterproofing: Polyurethane foam creates a waterproof barrier, preventing water infiltration and associated damages.
- Quick and Non-Disruptive: Injection process is fast, minimally invasive, and requires no excavation, reducing downtime and disruption.
- High Strength: Polyurethane foam expands and hardens, providing high-strength reinforcement to the concrete structure.
- Versatility: Suitable for various types of concrete structures and applications, including roofs, bridges, and tunnels.
- Cost-Effective: PU injection offers cost-effective repairs, avoiding the need for extensive reconstruction or replacement.
- Long-Lasting: Provides durable repairs, extending the lifespan of concrete structures and reducing maintenance needs.
- Environmentally Friendly: Polyurethane foam is non-toxic and non-hazardous, posing minimal environmental impact during and after application.
Liftpits
Acrylic coating systems applied to the negative side of basement lift pits involve applying a waterproofing layer onto the exterior walls of the pit. This method is typically used when access to the exterior side is feasible and when there is a high risk of water intrusion from the surrounding soil.
Advantages
- Prevents Water Infiltration: Forms a protective barrier on the exterior walls of the lift pit, preventing water from seeping into the structure from the surrounding soil.
- Long-Term Protection: Provides long-lasting waterproofing protection, reducing the risk of moisture-related damage to the lift pit and surrounding structures.
- Enhances Structural Integrity: Helps to maintain the structural integrity of the lift pit by preventing water damage and corrosion of the underlying materials.
Crystalline Admixture System
Crystalline admixture systems consist of proprietary blends of chemicals that are added to the concrete mix during batching or applied to the surface of hardened concrete as a slurry. These chemicals react with moisture and free lime in the concrete to form insoluble crystalline structures within the concrete matrix. These crystals grow and fill the capillary pores and micro-cracks in the concrete, effectively blocking the pathways for water ingress.
Advantages
- Permanent Solution: Provides a long-lasting waterproofing solution.
- Active Protection: Reacts with moisture to block water penetration actively.
- Enhanced Durability: Increases resistance to chemical attack and abrasion.
- Reduced Maintenance: Requires minimal upkeep after application.
- Versatility: Can be used in new construction or applied to existing structures.
- Environmentally Friendly: Many formulations are non-toxic and eco-friendly.
