| Waterproofing |
John-Luc Rizzo General Contractor
your house will absorb the water true the porosity and or crack of your foundations and footings and will definitely freeze in winter and by summer this frizzed water will create pressure against the inside footings and concrete and foundations destroyed in a few seasons pulverizing your house Integrity. This is why we don't do this type of system, in my personal opinion this system is rubbish. I'm wiling to challenge to the contrary of my opinion to engineers or architects as well the city code at any time they like. Because excavating on the exterior is expensive? yes it is and almost allways lieds to the repair of driveways, and landscaping, but this is something it should be done prior to all this, a less expensive alternative is sometimes employed from the building interior( We don't do it ) A drainage tile system is installed below the basement floor inside the footings. The water can then waste sewer system, gravity permits, or a sum pump. |
| EXCAVATION, DAMP PROOFING AND DRAINAGE TILE (costly but 100% effective) Basement are mostly below grade , therefor is vulnerable to water seepage. Water intrusion is perhaps the single must biggest cause of water filtration on foundation walls. Statistics tell us that basement leakage is the most common problem found in houses, over 90% of all basements will leak and suffer damage. Some evidence of moisture penetration can be found in almost every house. Water problems does not necessarily mean it was poorly constructed. Water can appear in even the most well-built home. Most all basement leakage problems are solvable, but, the majority of leakage problems can be solved by directing surface water away from the building, by re-grading around the foundation or/and using downspout extension to force rain water to flow away from the house. You should examine the basement and crawl spaces, look for clues that indicate a history of basement leaks and looks closely at the area around the house for conditions that can cause water to accumulate around the foundation. Wet basements cannot be assessed for their severity, frequency, and/or inconvenience factor during a one time visit. There may or may not be clues that indicate a history of basement dampness. Visible signs may be concealed by new paint or storage piled against the area. If there has been a dry period before the time of the inspection, signs of past water penetration may not be visible. Even if visible, the clues usually do not give an indication of the severity or frequency. Even a basement with no seepage problems during a heavy rain does not guaranty the basement will remain permanently dry. A single rain may or may not result in seepage. A heavy rain may not raise the groundwater level sufficiently to cause water to seep through the foundation walls. Moisture problems are also intermittent. In some basements, water penetration will occur after virtually every rain. In other basements, it will occur only after periods of prolonged rain, and in still others, it will only happen with wind driven rain or during a spring thaw. In most cases however, the resultant damage gives no indication of frequency |
