Delhi Metro Rail Corporation (DMRC) Phase III & Phase IV

Delhi, India

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

Sanford, USA

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

Ankara, Turkey

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.

Projects Using This Product

Dam & Irrigation

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.

Wastewater Collection & Treatment

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.

Water Treatment Plants

Canóvanas Filtration Plant

Puerto Rico

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.

Water Holding Structures

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.

Wastewater Collection & Treatment

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 Collection & Treatment

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.
