Polyurethane Foam Concrete Crack Repair Materials

Stop Leaking Cracks in Concrete Basements

Applied Technologies manufactures polyurethanes used to stop water leaks.  Concrete crack injection with polyurethane foam is the best way to stop a foundation wall crack leak. This is because the liquid urethane fills the entire foundation crack. Once inside the crack, it begins to foam and expand. The expanding foam completely fills it  and prevents future water leaks. Water will now remain outside of the basement wall and not be able to penetrate into the interior.

Fast and Inexpensive Concrete Crack Repair

A typical 8' foundation crack can be repaired in one hour. This is because there is no drilling or chiselling needed to widen the foundation crack. The low viscosity polyurethane can enter even hairline cracks with ease and stop your basement water leak.


Polyurethane Foam Concrete Foundation Crack Repair Advantages

  • Closed cell foam stops basement water leaks
  • Water stays outside of the basement
  • Strong bond to foundation concrete
  • Fills the basement wall crack entirely
  • Easy to use
  • No drilling or chiseling

Kits-Polyurethane Foundation & Basement Crack Repair

Applied Technologies packages kits for the contractor and Do-It-Yourselfer who wants to repair leaking basement wall cracks.

 

  • DIY and contractor size kits

Hydra Stop 300 Hydrophobic Urethane Foam 300 cc x 300ccHydra Stop 300 Hydrophobic Urethane Foam 300 cc x 300cc

6 Cartridges/Case

  • Low viscosity
  • Single component
  • 22 oz dual cartridge (300cc x 300cc)

Single component hydrophobic urethane foam stops water from leaking through concrete cracks,  Low viscosity formula gets into the tightest concrete cracks.  Once the foaming reaction is complete the finished product will not shrink.  Basement crack leaks are stopped from letting water into the living area.

Hydrophobic polyurethane foam.  Fits a standard caulk gun.


Hydra Stop 300 1 Gallon JugHydra Stop 300 1 Gallon Jug

Use a bulk 1 gallon jug to fill grease guns or pumps.  Inject through mechanical packers.  Same as the above product.


A-Tech Wet Hydrophobic Polyrethane FoamA-Tech Wet Hydrophobic Polyrethane Foam

6 Cartridges/Case

Stops water leaks through a foundation crack. Reacts with water already in a foundation crack or injected by a technician. On contact with water it begins to expand. When cured it forms a closed cell foam that prevents water penetration through the concrete crack.

A-Tech T-Dry Hydrophilic Polyurethane FoamA-Tech T-Dry Hydrophilic Polyurethane Foam

6 Cartridges/Case

A low viscosity two component hydrophilic urethane foam. Water in one cartridge mixes with A-Tech T-Dry to form an expanding foam. When cured it forms a flexible closed cell foam that stops water. It is designed to be used to seal moving, non-structural cracks. Mixes with water in the cartridge to react.

 

Uses 616 Static Mixer

A-Tech Dry Hydrophilic Polyurethane FoamA-Tech Dry Hydrophilic Polyurethane Foam

6 Cartridges/Case

Two component hydrophilic urethane foam prevents water from entering a foundation crackand leaking into the basement. Water in one cartridge mixes with A-Tech Dry to form an expanding foam. When cured it forms a flexible closed cell foam that stops water. It is designed to be used to seal moving, non-structural foundation cracks.

Fast curing foam.

Urethane Foam Foundation Crack Repair Vs. Hydraulic Cement Patching

To stop water from leaking into a concrete basement or concrete foundation crack, liquid urethane foam can be injected into the concrete crack. On contact with water, the liquid urethane foams and expands inside the crack.

Concrete basement crack repair by urethane injection entirely fills the crack. Not only from the bottom to the top, but the entire width of the foundation wall. The water stays on the outside of the foundation and the basement contents are safe. The foam created is a closed-cell structure that will not allow water to work its way through the basement crack. The finished foam bonds tightly to the surrounding concrete to ensure that water does not push the foam out of the foundation crack. Once the urethane has foamed and expanded inside the foundation crack, water cannot leak into the basement again.

In comparison, a patch repair using hydraulic cement is much less reliable. Hydraulic cement must have the crack chiseled out into a vee-notch. This is a long and messy process. The chiseled out notch is only a few inches deep. The hydraulic cement cannot be placed into the entire width of the concrete wall. Therefore, water still gets into the basement crack from the outside. Over time salts develop which break the bond between the hydraulic cement and the existing concrete foundation. This allows water to leak again into the basement.

A patch repair covers the inside surface of a foundation crack. This is a weakly bonded repair that the water can push off of the wall and allow water to leak into the basement.

Repair from the inside means no digging or messy excavation

Concrete basement and foundation crack repair is done from the inside of the basement. The home's outside landscaping does not have to be removed and the foundation excavated for the leak repair. Also, there is no drilling or chiseling to perform a foundation crack leak repair using Applied Technologies' products. The concrete basement crack is filled entirely by the concrete crack injection repair material. This stops water from leaking into a basement and keeps the possessions dry.

Applied Technologies manufactures a full line of concrete foundation and basement crack repair materials and foundation crack repair equipment. These products will stop your foundation and basement leaks and keep your basement dry and clean.
