Basement Foundation Wall Repair by Injection
A cracked basement foundation wall can be repaired to stop water from entering your basement with injections by our basement waterproofing contractor. Our injection method is effective enough that we offer a full lifetime transferable warranty with the purchase of our basement foundation wall injection service. In addition to our injection service, we offer other basement / foundation waterproofing services that will leave your basement dry and your basement wall protected from water seepage.
Epoxy Basement / Foundation Concrete Crack Injection
Epoxy crack injection does not only stop water but also provides structural strength. Like the familiar epoxy glue, it fills the crack and glues the concrete. Its strength and bond with concrete greatly exceed the strength of the concrete itself. And the high bond and tensile strengths of epoxy prevents further elongation and yawning of structural cracks. Epoxy low pressure crack injection method insures that the full depth and length of the crack is filled. It fills cracks in walls up to 24 inches thick.
Polyurethane Resin Basement / Foundation Concrete Crack Injection
Over 95% of residential basement cracks are non-structural - the only problem is the seepage of water. A polyurethane concrete crack injection does not add structural strength; it just forms a barrier impenetrable to water. Polyurethane resin remains flexible, which allows for continuous natural movement of the concrete due to thermal shrinkage and expansion or settling. It bonds tenaciously to dry or wet concrete. It can be used to repair wet or even leaking cracks. The polyurethane polymer forcefully expands, which ensures that the full depth and length of the crack is filled. It fills cracks in walls up to 24 inches thick. Polyurethane can expand over 20 times its volume. If there is a void on the backside of the wall, it will fill it too - there is no way for water to ever find the crack again. If the crack in the foundation wall is above ground, then we will seal the crack on the other side temporarily with a caulk. The polyurethane polymer has low viscosity to fill hairline cracks but expands to fill wide cracks (up to 3/4 inch). We use the highest-quality two-component polyurethane. There are inexpensive single-component polymers on the market but they are not suitable for repair of cracks subjected to water pressure. We use hydrophobic polyurethane, which repels water. In contrast, hydrophilic foams absorb water and when allowed to repeatedly dry out, like in a basement, they release the water molecules and slowly crumble.
Polyurethane can also be used to create a water-resistant seal in rod holes, cold joints, electrical conduits, septic projections, well/water lines, and many other applications.
Concrete Crack Injection
A basement / foundation wall concrete crack is the very kind of result that can occur in your basement foundation wall. This kind of crack can be the result of cracks that formed when the poured concrete cured, which widened due to settlement, hydrostatic pressure and shrinkage due to the freezing and thawing throughout the year.
Cold Joint Seal
Cold joints form when different sections of a concrete wall are poured at different times, resulting an unbonded area between the two sections of concrete wall. An example of this is where the basement floor meets the foundation wall. This space within the concrete wall can be sealed from the inside in most cases.
Electrical Hydro Panel Leak
The spot in the wall where Hydro enters can eventually leak, and if you noticed water in that area behind the panel board, or water leakage from the hydro conduit, it may be a sign that you suffer from a Hydro projection leak. Due to the danger of high voltage, it is necessary that a specialist with proper training inspect the area before proceeding with the repair from inside or outside.
For the purposes of a home inspection, honeycombing is mostly a cosmetic condition that is found only upon the exterior or interior face of the home’s poured concrete foundation. By and large, honeycombing is left untreated with limited to no adverse affects upon the performance of your foundation. However, depending on the specific location of the honeycombing, it could indicate a more deleterious condition. For instance, if the honeycombing was deep enough to allow moisture / water into the cavities that house reinforcement or post-tensioned cable anchors, corrosion could weaken the performance of the foundation. Anytime the structural components of your home´s foundation is being damaged corrective measures should be undertaken by a professional. In other situations the affected area may extend itself deeper into the mass of the concrete, in which case the only way to confirm the condition and treat it would be by way of a structural engineer which is in 95% of cases not necessary . This is a not-too-common condition and unless specifically addressed during a home inspection or specific evaluation, should not be added to your list of concerns except if its noted evidence of efflorescence or staining from water leaks.
Tie Rod Hole Leak
pipes are typically larger than the actual pipe itself leaving a void for water infiltration and leaking pipes. For example, a sewer pipe is generally 4 inches in diameter yet the hole through the concrete has a diameter of at least 5 inches or more. Using a two part resin that is injected into the void will stop water and prevent further leaking and other pipe repairs. This process works well for all pipe penetrations through poured concrete walls.
Tie rods or snap ties in a foundation can also be a source of water infiltration. These are the metal rods that are used doing the forming process of the foundation. Over time these rust and allow water to make its way through into the home. Again using a two part resin injected into these areas will stop water.
Tie rods, snap ties, and pipe penetrations can also be sealed by us from the inside without injecting, depending on the situation, with other 2 part adhesive (not hydraulic cement)
