Fosroc Renderoc Plug 5kg Rapid Setting Leak Sealing Mortar

Instant Solution for Active Water Leakage Problems

Water leakage in concrete structures is not just annoying—it damages walls, weakens structures, and increases long-term repair costs. Fosroc Renderoc Plug 5 kg is a high-performance, rapid-setting leak-sealing mortar specially designed to stop active water leaks instantly, even when water is flowing under pressure.

This professional-grade repair material is widely trusted by contractors, plumbers, and civil engineers for emergency waterproofing and repair work in basements, water tanks, lift pits, pipelines, and concrete cracks.

If you are facing continuous seepage, dripping cracks, or pipe entry leaks, this product gives you a quick, reliable, and long-lasting sealing solution.

What Makes Fosroc Renderoc Plug Powerful?

Unlike ordinary cement or repair compounds, Renderoc Plug is formulated to react rapidly with water and set within minutes. When applied to the leaking point, it expands slightly and locks itself into the gap, creating a strong watertight barrier that stops further water ingress.

This makes it the ideal choice for emergency leak repairs, where stopping water flow immediately is critical before applying any permanent waterproofing system.

Common Areas of Application

Fosroc Renderoc Plug is suitable for a wide range of residential, commercial, and industrial repair works, including:

• Basement wall leakage repair

• Concrete crack and joint sealing

• Water tanks and reservoirs

• Pipe entry and exit leak points

• Lift pits and underground structures

• Sewer and drainage structures

• Swimming pools and sumps

Wherever there is active water seepage or leakage in concrete, this mortar provides a quick sealing solution.

How the Product Works

The product uses a rapid hydration chemical reaction when mixed with water. This reaction generates fast setting and slight expansion, which helps the mortar:

• Fill the leakage gap completely

• Block water pathways instantly

• Create a tight mechanical bond with the concrete

The result is a permanent watertight seal that stops further leakage and prepares the surface for additional waterproofing treatment if required.

Step-by-Step Application Method

Using Fosroc Renderoc Plug is simple if done correctly:

1. Surface Preparation

Clean the repair area properly. Remove dust, oil, grease, loose particles, and weak concrete.

2. Cut & Shape the Leak Area

Chisel the crack or hole into a slightly wider shape inside (undercut shape) for better grip and bonding.

3. Mixing

Take a small quantity of powder and mix with clean water to form a stiff paste.
⚠️ Only mix small amounts because it sets very fast.

4. Application

Apply the mixed mortar immediately by hand or trowel and press firmly into the leaking point.

5. Hold & Set

Hold the material in place with pressure for a few minutes until it hardens and stops the water flow.
