Polyurethane injection systems are used for structural repair and waterproofing. It involves injecting polyurethane resin into cracks, voids, or cavities within building structures to strengthen, seal, and stabilise them. This method is valued for its versatility and effectiveness because the resin can expand and fill even the tiniest gaps, making it ideal for tasks such as concrete foundation repair and water leakage prevention. Selecting the right polyurethane product is important because it directly impacts the effectiveness and durability of the repair. Different formulations of polyurethane have distinct properties, including flexibility, strength, and curing time, making it essential to choose a product that matches these requirements. La Greens Polyurethane Injection Systems are the perfect fit for these needs.
La Greens Polyurethane Injection Systems
PyuFitt HF 100 – Single Component, Solvent-Free, High Foam, Quick reaction polyurethane Injection System
- High Water pressure leakages in Basement Rafts
- Below ground structures like Water tanks & Reservoirs, Retaining Walls etc.
A single-component, solvent-free polyurethane injection system ideally suited for crack injections, water leak repairs, and void filling in concrete and masonry structures. When it reacts with water, it forms a semi-flexible closed-cell polyurethane foam. It should be injected using a single-component pump and requires the addition of 5% to maximum 10% catalyst for optimal performance.
- Allows for adjustable reaction speed by varying the accelerator or catalyst content
- Offers excellent penetration into cracks due to the formation of CO2 during the reaction.
- Does not shrink or swell, and it achieves good compression strength rapidly.
- Foam expansion capability, ranging from 3000% to 4000%, ensures effective void filling.
- Repairing cracks in concrete and masonry structures.
- Sealing water leakages with high water flows.
- Filling voids in concrete or cavities in rocks.
Pyufitt Elastic LV – Two Component, Solvent-Free, Low Viscosity (LV) Hydrophobic Polyurethane Injection System
- Construction joints, Cracks in Roof Slabs and Podium Slabs
A two-Component, solvent-free, low-viscosity (LV) polyurethane injection system designed for effectively sealing cracks in concrete structures. It comprises a resin component and a specialized isocyanate (MDI-based) component. This system can be injected using a one-component pump.
- Elastic sealing of cracks in concrete structures, allowing for flexibility in sealing.
- Can be used directly in cracks that are dry or moist, making it versatile for various conditions.
- Used in construction and civil engineering for new structures or repair purposes.
- For aggressive water leakage, it can be used in combination with PyuFitt HF100 for more effective water stopping.
- Permanent sealing of dry or wet cracks in concrete, stone, and masonry.
- Sealing of low movement cracks/construction joints in terraces, podiums, toilets, RCC slabs, P T slabs, etc.
PyuFitt HF 100 offers a solvent-free, high foam injection system, making it eco-friendly and ideal for void filling. PyuFitt Elastic LV, with its low viscosity and hydrophobic properties, is perfect for water-resistant applications, thanks to its two-component, solvent-free design, enhancing versatility.
