Patch’n Plug
Xypex Patch’n Plug is a specially designed, fast-setting hydraulic cement compound for concrete patching and repair. It stops flowing water in seconds and is used to seal cracks, tie holes, and other defects in concrete. The high performance characteristics of Patch’n Plug are enhanced by Xypex’s unique Crystalline Waterproofing Technology.
Advantages of Xypex
- Single component (simply add water)
- Very rapid setting
- Contains Xypex’s unique crystalline chemistry
for self-healing of cracks and other defects - Quick return to service of water holding structures
- Cement based – compatible with concrete and
masonry substrates - Non-toxic
- No VOCs
- NSF 61 certified
Recommended for
- Stopping an active flow of water through cracks
- Repair of concrete substrates before the application of Xypex coating materials
- Repair of leaking construction joints
- Sealing around pipe penetrations

General Resources
Delhi Metro Rail Corporation (DMRC) Phase III & Phase IV
Due to the success of the Xypex surface-applied and repair system in various projects, the Delhi Metro engineering team consulted Xypex to provide a waterproofing solution for phase III. The engineering team specified Xypex Admix C-2000 NF and Xypex Concentrate for the waterproofing of phase III underground stations in conjunction with spray applied membranes on the rooftop slab.
Yankee Lake Regional Wastewater Treatment Facility
To start repair works, the general contractor, Crom Corporation, first blasted the old concrete surfaces with a 3,000-psi pressure washer to remove the old epoxy coating, then disinfected the substrate to remove bacteria present on the surface. After these steps, cracks and joints were repaired with Xypex Patch’n Plug and Concentrate.
Köse İvedik Trade Center
The project engineers solved the problem differently;
instead of applying a membrane, they poured concrete
that incorporated Xypex at the batching stage.
Xypex Admix C-1000 NF was used to waterproof
over 15,000 cubic meters of concrete placed in the
structure’s basement from the casting stage. Also,
tie-rod holes and cold joint areas were repaired with
Xypex Patch´n Plug and Xypex Concentrate.
ETI Aluminum SludgeTank Rehabilitation
For the concrete unsuitable for repairs, Xypex Admix C-1000 NF was placed to rehabilitate the tank by casting a new concrete layerthe over the pre-existent structure, corners were chamfered using Xypex Patch‘n Plug.
799 Clifton Road (Home Repair)
This 1915 home, designed by renowned Atlanta architect Neel Reid, is located in the historic Druid Hills neighborhood. It was updated by owner and architect Sheila Lee Davies, AIA, in 2019. The full renovation included the main house and a cottage, and the addition of a new meditation pavilion, swimming pool and garage. Persistent water seepage in a cast-in-place concrete tunnel underground walkway linking the house to the pavilion was sealed with Xypex crystalline waterproofing products.

Projects Using This Product
The Rihand Dam
Being one of the oldest dams in India, the concrete of the dam body has experienced deterioration due to ageing and AAR (Alkali Aggregate Reaction) resulting in cracking and surface loss. Xypex’s unique crystalline technology was chosen as the preferred repair solution due to its cementitious nature and compatibility with concrete along with other technical reasons.
Sydney Harbour Tunnel
Commencing in September of 1991, repair systems using Xypex Concentrate and Patch’n Plug were used as part of an ongoing program of repair and maintenance of the North and South land driven tunnels and transition tunnels of this renown structure.
AASS Wastewater Treatment Plant
The walls of this plant were cast using the Machihembrado method. Because of this approach, Xypex Dry-Pac and Xypex Patch’n Plug were required to seal the construction joints. The same Xypex treatment was used on 518 m of cold joints and cracks. After these structural defects were repaired, the surfaces were treated with a two-coat application of Xypex Concentrate.
Canóvanas Filtration Plant
The thickening tank (92 ft. diameter by 15 ft. deep) of this filtration plant used Xypex Patch’n Plug to repair structural defects followed by a coating of Xypex Concentrate. Upon review, the Xypex treatment proved to be very successful, rendering the tank impenetrable by water.
Chehe River Mine
Xypex products were chosen to rehabilitate these pipes as they resist hydrostatic pressure, chemical attack and are a permanent solution thus avoiding future maintenance intervals and shutdowns. Additionally, they are used on wet concrete so removing the need to dry out the concrete before application. Xypex Patch’n Plug was used to seal active leaks in the pipe joints.
Fiat India Automobiles Private Ltd.
More than 13,000 lbs of Xypex Concentrate and 1,000 lbs of Xypex Patch’n Plug were used to waterproof a surface area of 60,000 sq.ft. Xypex was chosen for its additional benefit of chemical resistance and concrete durability enhancement.
Wastewater Tunnel Repair
The first phase of the project required the Bawax applicator to fill in all of the joints between the precast culvert sections with Xypex Patch’n Plug fast-setting hydraulic cement compound. Patch’n Plug stops flowing water in seconds and is used to seal cracks and other holes or defects.
