Basement Crack Repair Experts


Concrete Often Cracks

Crack being injected using our high pressure polyurethane method (floor cracks excluded)

It is universally recognized and experienced. Concrete construction requires construction joints and cold joints.


All of these wanted and unwanted openings in concrete structures may cause very serious problems. One of them is water leakage. Freeze/thaw damage and corrosion of rebar resulting in structural weakness and even failure can all be attributed to cracks and water infiltration.


Now most of these problems can be economically resolved utilizing HomeSpec’s Pressure Polyurethane Injection System.


It has been proven to accomplish two major purposes: one is to stop water leakage permanently, and the other is to maintain or even restore design strength.


Basements, crawls, slabs on grade, construction or control joints, parking garages, manholes, tanks, dams, and many other structures can now be fixed permanently.


 

Epoxy injection resins usually fail

Some high pressure injection ports and supplies

Epoxy injection resins usually fail in stopping active water leakage because of their slow reaction time and inability to bond to wet surfaces; this failure is resolved with HomeSpec’s High Pressure Injection Polyurethane System.

The actively flowing water is stopped by injecting urethane grout which reacts quickly with the water to form an expanding foam. The final product is a semi-rigid or flexible closed-cell and strong bonding seal. To control the speed of the chemical reaction, a certain percentage of an accelerator is added. The amount of accelerator added, controls gel times between a few seconds and several minutes.


 

Low Pressure Injection Techniques

Injection in Poured Concrete_224x660Since the low pressure injection techniques that utilize ‘glue on’ surface ports are more commonly known, the following introduction focuses on the high pressure injection in conjunction with mechanical packers. Mechanical packers eliminate many problems of the surface ports including bond failure at pressures above 300 psi and inaccessibility in wet, and water pressured areas.


High pressure injection through mechanical packers opens a new dimension of possibilities to solve joint and crack related problems. Besides crack injection it is also possible to inject polyurethane grout to the back side of a wall into the soil thus creating a grout curtain. This procedure is necessary when well defined cracks, joints or openings of any kind cannot be detected but moisture infiltration is evident.


Another option is injection of the void between the structure and an existing membrane that had initially been installed to prevent water leaks, but failed. Membrane failure is a common cause of below grade water leaks. To the dismay of any engineer, it often occurs on brand-new buildings. The HomeSpec High Pressure Injection System has been proven to be a superior system in correcting those failures with ease by injecting from the negative side. No digging is necessary.


Voids in the structure can be sealed, defective membranes can be fixed and even water pockets behind the structure can be effectively filled to minimize hydrostatic pressure.


The injected soil will be compacted and stabilized thus reducing water accumulation behind the structure and shifting of loose soil. Extensive soil injection can prevent landslides and therefore minimize stress on the foundation. The number of practical methods that have been established over the years is endless. The Pressure Injection System has been proven to be extremely versatile, reliable and economical in resolving water related and structural problems.

General Information

Tunnel Project_400x300

The High Pressure Injection System can be used for injecting cracks, cold joints, expansion joints and for soil stabilization. The system can be used to stop gushing water, to seal minor seepage, to regain structural integrity and to waterproof and strengthen almost any concrete or masonry structure from the positive or negative side, below grade, above grade and under water. This versatile system is used to solve problems in small residential objects as well as problems in major commercial structures. The system includes epoxy injection techniques as well as polyurethane injection techniques.

We offer Carbon Fiber Staples from Fortress Stabilization Systems to add strength to fractures in concrete. This allows the homeowner or business to achieve strength, while preventing water intrusion.

 

 


 

EPOXY RESINS INJECTION TO ACHIEVE STRUCTURAL STRENGTH

Semi-flexible and flexible sealants are usually the best solution for crack and joint related problems. Nevertheless there are conditions where structural repair is necessary and specified. Structural strength is achieved by using epoxy injection resins.


Due to the unique properties of the slv (super low viscosity) epoxy injection resins, it is possible to inject this resin deeply into concrete joints, hairline cracks and fissures. HomeSpec’s epoxy resins provide very high bond and compressive strength, and can restore cracked concrete to a complete monolithic piece.
