1. Introduction: What is Robust Power Plug?
Robust Power Plug is a fast-setting hydraulic cement compound designed for instantaneous stopping of active water leaks in concrete structures. It reacts immediately with water to form a strong, durable, and watertight seal — even under pressure.
This specialized compound from Robust Construction Chemicals is engineered for emergency leak sealing applications such as basements, tunnels, tanks, retaining walls, foundations, and water reservoirs where conventional repair materials fail.
Key Purpose
-
Instant leak arresting in running water or seepage zones.
-
Waterproof plugging for cracks and voids in concrete.
-
Emergency sealing of active leaks in civil and industrial structures.
2. Product Overview
Robust Power Plug is a cementitious, non-shrink, and chloride-free hydraulic plugging compound. When mixed with water, it forms a plastic mortar that sets within 30–60 seconds, depending on temperature and conditions.
It expands slightly during setting, ensuring a tight mechanical seal against active leaks. Once cured, it becomes waterproof, durable, and resistant to hydrostatic pressure, making it suitable for both positive and negative side waterproofing repairs.

-
Identify the Source
Trace the exact path of water ingress. Drill or chisel a small “V” groove or notch around the leakage point. -
Clean the Surface
Remove all loose particles, dirt, grease, oil, or laitance. The surface should be sound and roughened slightly for grip. -
Pre-Dampen the Surface
Dampen the area with clean water to achieve SSD (saturated surface dry) condition — but ensure no standing water.
7. Mixing Instructions
Material Required:
-
Robust Power Plug powder
-
Clean mixing bowl
-
Small trowel or hand glove
Mixing Method:
-
Mix a small quantity only (enough for one application, as setting is very fast).
-
Use 3 parts powder to 1 part water by volume (approx. 20–25% water by weight).
-
Mix quickly by hand until a stiff, dough-like consistency is achieved (within 15–20 seconds).
-
Immediately apply to the leak.
Do not mix large batches. Prepare small portions and use within 30–45 seconds.
8. Application Procedure
Step-by-Step Instructions:
-
Preparation of Plug:
Mix small quantities as described to form a thick paste. -
Application:
-
Use gloved hands or a trowel.
-
Press the mixture firmly into the leaking point or crack.
-
Hold it in place with firm pressure for 30–60 seconds until it sets.
-
-
Finishing:
-
Once set, trim excess material smoothly using a trowel.
-
After initial setting, apply Robust Crystalline Coating or Robust Waterproof Coating for enhanced protection.
-
-
Post-Application:
Keep the repaired area moist for 15–30 minutes to aid curing.
9. Application Tips and Professional Advice

Robust Power Plug – Instant Stop Leak Cementitious Compound (Extended Details)
1. Working Principle of Robust Power Plug
The core technology behind Robust Power Plug lies in its hydraulic cement chemistry. When water is added, it initiates a rapid hydration reaction, producing compounds such as calcium silicate hydrate and ettringite, which expand slightly during the setting phase.
This expansion exerts pressure against the surrounding concrete, ensuring a tight mechanical and chemical bond. The material hardens even under flowing water, forming a watertight crystalline plug that stops further leakage immediately.
The unique blend of high-grade cement, chemical accelerators, and proprietary waterproofing agents allows Robust Power Plug to perform effectively under pressure conditions up to 5 bars, making it reliable for both domestic and industrial waterproofing requirements.
2. Chemistry Behind Instant Leak Stopping
Traditional cement mortars fail in active water flow due to delayed setting and shrinkage.
Robust Power Plug, on the other hand, uses modified hydraulic binders and fine fillers that absorb water rapidly and initiate instant setting.
Within 30–60 seconds, the mixture transforms from a pliable paste to a rock-solid plug.
This reaction:
-
Stops the leak immediately
-
Strengthens as hydration continues
-
Expands microscopically to seal micro-gaps and pores
-
Becomes fully waterproof once cured
The internal crystalline structure ensures long-term impermeability, preventing reactivation of leaks even under variable hydrostatic pressure.
3. Why Choose Robust Power Plug
Choosing Robust Power Plug means choosing speed, reliability, and durability in leak repair. Here’s why professionals prefer it over conventional solutions:
A. Speed of Action
Sets in less than 1 minute, allowing quick continuation of waterproofing jobs.
B. Permanent Repair
Not a temporary fix — forms a permanent watertight structure within the concrete.
C. Strong Adhesion
Bonds tightly with both new and old concrete, masonry, and stone surfaces.
D. Easy to Use
Requires only water and can be mixed on-site within seconds — no primer or bonding agent required.
E. Works in Damp and Wet Conditions
Perfect for emergency use in running water, flooded basements, or leaking tanks.
F. Cost-Effective
Reduces downtime, labor, and material wastage, resulting in significant cost savings on site.

5. Application Method – In Depth
Step 1: Leak Identification
Locate the source of leakage. Mark the exact area to ensure targeted application.
Step 2: Surface Preparation
Chisel out a V-groove (approx. 20 mm wide × 20 mm deep) around the leak to provide an anchoring cavity. Remove all debris, grease, and dust. Keep the surface damp but without standing water.
Step 3: Mixing
Mix Robust Power Plug with clean water at a ratio of 3:1 (powder:water). Stir by hand for 15–20 seconds until a uniform stiff paste is achieved.
Step 4: Plugging
Using a gloved hand, form a ball of the mixture and press it directly into the leak point. Hold firmly for 30–60 seconds until it sets.
Step 5: Finishing
Smooth the surface with a trowel after initial hardening. Allow it to stand for a few minutes before applying any coating.
Step 6: Protection
Once the leak is stopped, apply Robust Crystal Guard or Robust PU Liquid Rubber for complete waterproofing.
