💦 Injection Grouting Waterproofing – Permanent Solution for Water Seepage
By Inotic Infra Solutions | Serving Delhi NCR | Professional Waterproofing Contractors
🧰 What is Injection Grouting Waterproofing?
Injection grouting is an advanced waterproofing method where specialized chemical grout is injected under pressure into cracks, voids, or honeycombed concrete structures to seal leakages. This technique ensures deep penetration and long-lasting waterproofing in areas prone to water seepage or structural damage.
It is highly effective in basements, lift pits, water tanks, tunnels, podiums, and even rooftops where conventional waterproofing fails.

- And other related tools
⚙️ Procedure of Injection Grouting
Site Inspection & Crack Mapping:
Our experts inspect the site thoroughly, marking all visible cracks and leakage paths.Drilling Injection Ports:
Holes are drilled at a 45° angle to intersect the cracks or voids from both sides.Cleaning & Flushing:
Dust, dirt, or loose particles are flushed out with water or air.Fixing of Packers (Injection Nozzles):
Mechanical or surface packers are installed in drilled holes.Injection of Grouting Material:
Using high-pressure pumps, PU (Polyurethane) or epoxy-based grout is injected into the cracks to fill and seal.Curing & Surface Sealing:
After injection, the surface is sealed, and the material is allowed to cure.Final Inspection:
A final inspection ensures no active leakage and confirms success of the treatment.
🧪 Materials Used
PU (Polyurethane) Grout: Flexible, expands on contact with water, ideal for active leakages.
Epoxy Grout: Rigid, high strength, best for structural repairs and dry cracks.
Acrylic Gel: Used for sealing around joints and in water-retaining structures.
All materials used are of IS-standard and brand-certified, such as:
Sika
Fosroc
Dr. Fixit
BASF MasterSeal
STP
And others
