MAXPLUG: Rapid-Setting Hydraulic Cement for Emergency Leak Stopping

Instant Water Leak Repair Under Pressure in Concrete and Masonry

MAXPLUG is a high-performance, quick-setting hydraulic mortar engineered for one critical purpose: to stop running water leaks instantly, even under significant pressure. This cement-based product undergoes a slight expansion during its rapid set, ensuring it locks tightly into cracks, holes, and openings without shrinking away. It begins hardening within seconds and achieves a full set in just three to five minutes, making it the ultimate emergency repair solution for active water ingress. Its ability to set underwater and develop high compressive strength quickly makes it indispensable for urgent infrastructure and building repairs.

Unmatched Versatility for Critical Repair Scenarios

The application range for MAXPLUG is vast, covering any scenario where water needs to be stopped immediately. It is the preferred material for sealing active leaks in basement walls, tunnel linings, elevator pits, and sewer systems. It can perform emergency repairs on broken or leaking water pipes, even while the pipe is under pressure. Beyond leak stopping, its rapid strength gain makes it ideal for anchoring bolts and fixtures that require immediate load-bearing capacity, as well as for forming watertight coves at cold joints between slabs and walls in swimming pools and water tanks.

Controlled, High-Strength Performance for Professionals

MAXPLUG offers professionals a high degree of control and predictable performance. The set time can be manipulated by the water temperature—using warm water to accelerate and cold water to slow down the reaction, providing a crucial window for application in varying site conditions. Once set, it achieves a compressive strength of 38 kp/cm² in just 30 minutes, rising to 407 kp/cm² after 28 days, making the repair permanent and robust. It is non-toxic, chloride-free, and safe for use in contact with potable water, ensuring compliance with critical health and safety standards.

Reliable Emergency Solution with Straightforward Application

Supplied in 25kg drums and 5kg cans for job-site convenience, MAXPLUG requires only the addition of clean water for activation. The key to success is proper surface preparation, involving the cutting back of cracks to a sound, dovetail profile, and mixing small, workable batches by hand. With a 36-month shelf life in unopened packaging, it is an essential component of any maintenance kit for civil engineers, plumbers, and building managers. When an unexpected leak threatens a project or property, MAXPLUG delivers a fast, dependable, and permanent solution.

Product Limitations

  • Not suitable for sealing expansion joints or cracks subject to ongoing movement (use flexible sealants like Maxjoint Elastic).
  • Requires proper surface preparation: cracks must be cut to a minimum depth and dovetail profile for mechanical key.
  • Not for use as a general-purpose mortar or coating; designed specifically for plugging and patching.
  • Small batches must be mixed and applied quickly (within 3 minutes) to avoid hardening in the container.
  • Not designed for applications requiring long-term flexibility.
  • As a cementitious product, requires protective gloves during hand application to prevent abrasion.
