PURINJECT 1C FLEX
Product Price: Rs 1,400 / KgGet Best Price
Product Brochure
Product Details:
| Packaging Size | 25 kg |
| Physical Form | Liquid |
| Color | Transparent |
| Usage/Application | Waterproofing |
| Method Of Grouting | Pu injection |
It is solvent‑free.
Designed especially for wet, dynamic cracks and joints in concrete and masonry. That means it can handle cracks where there is water presence and possibly movement.
---
Key Properties / Features
Feature Detail
Viscosity / Flow Low viscosity, which helps penetration into fine cracks. Flexibility Forms a very flexible closed‑cell foam on reacting with water. Reaction via Water The resin reacts with the water in the crack to form the foam. Use of Catalyst Requires catalyst/accelerator (about 6‑10%) to adjust the reaction speed. Injection Method Injected using a one‑component pump system.
---
Applications
Sealing and waterproofing wet, moving cracks or joints in concrete structures where moisture or water leakage occurs.
Use in dynamic structures—where there may be expansion/contraction or small movements.
---
Advantages / Why Use It
Good adhesion even in damp or wet conditions, thanks to its hydrophobic nature.
Since it’s flexible, it can tolerate movements (crack widening/narrowing) without failing.
No solvents, which generally makes for safer handling and lower environmental/health impact.

PURINJECT 1C 115 ECO
Product Price: Rs 1,100 / KgGet Best Price
Product Brochure
Product Details:
| Packaging Size | 25 kg |
| Physical Form | Liquid |
| Color | Brown |
| Usage/Application | Waterproofing |
| Method Of Grouting | Pu injection |
It is a one‑component, solvent‑free polyurethane injection resin.
Designed for injecting into cracks or water leaks in concrete and masonry, or for sealing water ingress.
When it comes into contact with water, it reacts and forms a slightly flexible polyurethane hard‑foam (semi‑rigid foam).
---
Key Properties / Technical Details
Property Value / Description
Viscosity Ultra‑low viscosity, about 96 mPa·s. Reaction Time (“gel” time or foam formation) Between 9 to 70 seconds depending on the catalyst amount. Catalyst Needs 6‑10% catalyst to adjust reaction speed. Density / Foam Expansion Has a high expansion: up to 40 times (40 V expansion) in volume under certain conditions. Compressive Strength About 48.5 MPa when cured. Hydrophobic Yes — cured product repels water. Solvent / Phthalate Status Solvent‑free and phthalate free.
---
How It Works / Application
Mixed with catalyst (6‑10%) then injected using a one‑component injection pump into the cracks, joints or areas of water ingress.
Because it's hydrophobic, the reaction is triggered by contact with water. As the resin reacts, CO₂ is produced, which helps the foam expand and fill the crack/voids.
The foam is slightly flexible (semi‑rigid), which allows some movement without cracking.
It does not shrink and does not swell excessively.
---
Advantages / What Makes It Useful
Very good penetration into fine cracks because of low viscosity and foam expansion.
Can effectively seal leaks in damp or water‑bearing cracks.
Good mechanical strength and durability once cured.

Purinject 1C Soil
Product Price: Rs 1,250 / KgGet Best Price
Product Brochure
Product Details:
| Packaging Size | 25 kg |
| Appearance | Brown liquid |
| Relative Density | 1.12 kg/l @25°C |
| Flashpoint | Above 150 °C |
| Viscosity | < 25 mPa.s at 25°C |
| Shelf life | 12 months @ 20°C |
It’s hydrophobic and forms a closed‑cell foam/geotechnical foam when cured.
Designed for soil stabilization and also for creating horizontal or vertical waterproof barriers in soils.
---
Key Properties / How it works
Low viscosity: Before reaction, very low viscosity pre‐polymer, so it can penetrate into fine soil pores or fine sand.
Water‐reactive: The reaction is triggered by contact with water. In that reaction, carbon dioxide gas is generated, which helps form the foam and increase viscosity, helping penetration in fine soils.
Rigid cured foam: After curing, it becomes rigid polyurethane, with excellent compressive strength. It resists compression well.
Hydrophobic and chemically resistant: The cured product is hydrophobic (repels water) and has resistance to chemical attack.
No shrinkage or swelling: After it cures, it doesn’t significantly shrink or swell.
---
Use / Applications
Soil stabilization of saturated or water‑bearing soils, or soil layers needing reinforcement.
Forming waterproof barriers in soil (both horizontal and vertical).
Sometimes can also be used for crack repair in concrete, though that is more secondary.
