Mortar joints between masonry bricks in your foundation is a common location of water leaks. Mortar deteriorates over time and allows water to seep in through small holes. Generally this is due to poor quality masonry work when the foundation was first installed or poor material (cheaper brands bondings). Over time any minor flaws can be taken advantage of by time and shifting soils. Also keep in mind that no one can predict masonry walls even when the job is very well done. Water and soil can always find a way so long as your yard grading is not up to date and have no waterproofing system available to assist.
If there is significant damage to the mortar joints and foundation concrete, an external solution may be necessary. We can install an external, waterproof membrane to contain water and prevent it from building up against the outside of your foundation.
With or without serious damage, our team provides a masonry sealant and bondage to close the opening as an effective basement waterproofing tactic for leaking cinder block walls. The bond we use is impervious to water and natural wear and tear. No matter how bad the situation is, as long as you have a mason foundation wall with leaks you're going to want to call us for a permanent seal.
