Our Services Unlike many contractors who offer only one solution to all basement leak problems, we employ a wide variety of techniques, depending on your foundation and it's requirements.
Interior basement leak repairs-foundation repairs (snap tie/rod holes, cracks) Exterior excavations, block, poured concrete, stone, etc. Window well drainage repairs and installations-excavations Weeping tile installations/replacements Interior waterproofing and drainage systems Brick, concrete and masonry water sealants

(Cracks, snap tie, beam pockets, window leaks and honeycomb)
In most cases cracks are not a cause for concern from a structural point of view, but more of a leak concern. Most interior water sealing can be done with an injection system. The technician sent out to do your repair will go through a series of steps before injecting an expanding poly-urethane resin into the crack. The urethane is injected into the centre of the crack at a rate of pressure up to 3000psi, until the material is seen coming out on the other side of the foundation wall. During its reacting stage the urethane will expand up to 10 times its’ size in volume and fill the void in the concrete, from the bottom to the top and from the centre to both sides of the foundation wall. Leaks through cracks, snap ties, honeycombing and beam pockets all follow the same procedure. Leaks around windows may also be due to gaps around the window that may require the window to be replaced or may also be due to poor caulking. Thorough assessment of the window will identify the problem, in order to have a proper repair completed and the leak stopped. Urethane is an expanding material that once cured will absorb any foundation movement and give the wall a permanent seal that will not allow any further water to come through. The poly-urethane resin was developed for repairs in electric dams, subway tunnels, parking garages and man holes and has a life span of 500 years when not in contact with the sun. It does not shrink, crack or dry, but remains more of a rubber/sponge like material. It is non toxic and odorless. |

Although structural cracks are not very common, our technicians can resolve the problem. The repair is very similar to a Urethane injection, in procedure. The material however is an epoxy and is strictly for structural integrity and but can also provide a waterproof seal. Epoxy injection is a permanent and affordable way to fix for structural cracks in poured concrete without having to rebuild your home. Completed from the inside it glues the wall together with a bond stronger than the original concrete. |

(Poured concrete, block foundation, stone) (Cracks and rod holes) In some cases when a basement is finished, most people prefer to approach the basement leak problem from the exterior of their home.
In this situation upon determining the location of the leak, the foundation wall would be exposed and a repair would be approached from the outside. Similar as to when the home was originally built, except for now we must remove any landscape and other finishes that has been installed after the fact. Sometimes this repair involves a larger portion of your home; other times a small area is all that is required. Our six step procedure will ensure you of no basement leak problems for years to come. Step one, clean off the wall. Step two and three deal with a double layer of tar on any existing cracks and holes, both in poured concrete and block foundations. Step four; we install a rubberized, tar base membrane in the area of repair. Step five is to install a dimpled platon membrane with a 24mil thickness over the area of foundation walls that has been exposed, keeping a moisture barrier between the foundation wall and the soil around your home. This dimpled platon protects the tar base rubberized membrane from tearing during backfill and ground settlement. Step six is to seal the membrane along the edges keeping a seal that does not allow any water to get through. Due to the dig, sometimes gravel may be lost; therefore we will supply and install additonal gravel around the weeping tile before the backfill. |

Window Well Drainage Repairs or Installations
Window wells clog, most times just because they’re not maintained. Sometimes cleaning out the top of the window well is sufficient but not in all cases. When a weeper exists, it may need to be cleaned out and new gravel installed. Severe clogs may need to be dug. When a weeper does not exist, the window area must be dug to the footing, a weeper and gravel installed at the window along with the proper size well. |

Weeping tile Installations/Replacements
If the problem of your basement leak is due to a clogged/broken weeper, it can not be cleared out, the only solution is to dig around your home, remove the old clogged/broken weeping tile and have it replaced with a new weeping tile. This repair is more typical of a house over the 50 year mark, due to original clay weeping tile or maybe no weeping tile at all. Older weeping tiles may clog due to older, larger trees and their roots growing into the weeper or due to poor soil conditions. Similar to building a new home, the full exterior of the home is excavated; all shrubs, curbs, concrete and/or gardens must be moved or removed. After the excavation is complete, down to the footing, a new drain system is installed and along with adding sufficient gravel (approx 12 inches) we seal the wall to eliminate any further problems with leaks in your foundation. |

(Block foundations where expensive landscape may be a factor)
The concrete around the exterior walls of your house must be broken. A trench leading to a floor drain or sump pit will also need to be cut and dug. The bottom row of blocks is drilled to allow any water remaining in the block to have an escape route. The weeping tile (perforated pipe) and gravel is installed, against the footing on the inside of your foundation. The waterproofing dimpled wrap is installed on the interior walls to allow any moisture that comes through a guide directly into the weeping system. Upon the completion of the wrap and weeping system, new concrete will be installed. Not the best solution, in essence the water is only being re-routed and you may still have some dampness in your basement over the years. Using a dehumidifier will resolve this problem. |

(Clogged, incorrectly installed)
In some cases your sump pump and pit may break down, clog or may have been installed incorrectly. We can resolve the problem. If the pit needs to be dug down to be corrected or the pipe needs to be replaced, they can be easily noted, however, something more technical may take more investigation to determine the cause, before a solution is determined. Sump pumps do require periodic inspection. The automatic float switch may wear out and keep the pump working continuously or not at all. The pumps vibration may cause the pump to move slightly and the float may get caught on the edge of the sump crock. Pumps should come with check valves to prevent backflow when the pump stops running. This will save wear on the pump motor. If the pump motor burns out, it won’t do the job it’s there to do. To replace the pump system itself, why would you pay someone else. |

Brick, Concrete and Masonry Sealants
Brick that starts to flake will cause basement leaks sometime in the future. Having these flaking bricks replaced and the entire section waterproofed will prevent future problems, and no one will be the wiser. When the rain hits the wall it will trickle down instead of absorbing through the brick. Siloxane treats the brick allowing it to breathe yet be waterproofed. This material is not available in retail stores, some materials resembling it are, but they are not as effective. Waterproofing the brick not only saves your brick, it keeps water out of your basement. Sealants may also be needed due to driving rains constantly hitting the same wall, the brick can only hold so much rain and then it absorbs like a sponge. |

With the cracking of your foundation you may notice the definite signs of the mortar joints starting or continuing to crack due to continued foundation shifting. After the foundation is repaired this should be addressed. The mortar joints in the bricks are cleaned out and new mortar is installed. If this damage was originally due to brick saturation, it may also be necessary to waterproof the bricks and mortar joints. |
