Basement Waterproofing Upper Uwchlan Township, PA
Anytime you are building a structure above or below ground, waterproofing is an essential step in the maintenance and foundation of your project. A properly waterproofed basement should include sealants and drainage options. This is imperative in locations that are known to have water build up. This build up causes hydrostatic pressure which can force water or moisture through cracks in your foundation – leading to structural damage, mold and even decay. Waterproofing is a smart pre-emptive measure to take to avoid these issues cause by moisture.
—>Dry Ice Blasting
Lately, various companies have started to use a method in mold removal called “dry ice blasting” in the remediation of mold from surfaces like wood or cement. There is also a method called “soda blasting” which has proven to be very effective in the eradication of mold and mold spores on various surfaces.
—> Wet Vacuuming
These types of vacuum cleaners are designed to remove water and moisture from carpets, floors and various surfaces where water has appeared. You should only wet vacuum on wet materials or surfaces since mold spores can become present in the air inside if not enough liquid is present. Once used, the vacuum and it’s parts must be thoroughly cleaned and dried as mold spores can latch on to every surface on the interior and exterior of the tank.
—> Damp Wipe
This describes the removal of mold from any non-porous surfaces by way of scrubbing or wiping using water and detergent. You should use great caution to ensure that the material you are damp wiping can dry quickly so as not to produce further mold growth. Surfaces like glass, metal, hardwood, concrete, and plastic should be scarped down as much as possible before damp wiping. Then you should scrub the surface with either a fungicide or moldicide detergent.
—> HEPA Vacuum
HEPA stands for ‘High Efficiency Particulate Air’, these vacuums are used as the final clean-up step of mold remediations following materials being dried and contaminants being removed. They are recommended in the clean-up of any outdoor areas surrounding the effected area. Throughout this process the workers should wear the appropriate ‘personal protective equipment’ (PPE) to eliminate mold exposure.
—> Damaged Materials and Debris Disposal
Any damaged materials and furniture or belongings should be put into impenetrable bags or containers while they are in the remediation area. Once finished, these items can generally be disposed of as construction waste.
—> Sump Pump Repair
The job of a sump pump is to excess water from your basement or crawlspace away from the foundation walls of your home. That is to say, that the best method to prevent basement flooding is to properly install a sump pump.
Sump pumps are pumps that are used to remove any water that has accumulated in a sump basin that is generally found in your basement. Water can enter through the perimeter drains in
your basement and funnel into the basin. Alternatively water could enter due to rain or natural ground water and collect there if your basement is below water table level.
If basements flood regularly sump pumps are a good solution for dampness where the foundation of the home rests below the water table level. These pumps send the water away from your home to a place where it is not problematic – ie. storm drains or dry wells.
—> French Drains
These systems are generally used in the prevention of surface and ground water that can penetrate and damage the foundations of buildings. There exist two types; internal and external French drains.
Internal French drains are installed under the basement floor inside the perimeter of your basement, while external drains are is installed outside of the foundation walls prior to the soil being backfilled. The exterior tile is laid down on the bottom of the excavated area, while a layer of stone is put on top. Sometimes a filter fabric is even laid on top of the stones to keep any fine sediment or particles from penetrating. After the drain has been installed, that area is then backfilled with soil and the system is generally left alone to its job; unless it clogs.
Although external French drains can operate for about ten years without needing any maintenance whatsoever, they are prone to clogging without warning and could eventually lead to a flooded basement. When a drain is installed without the use of a filter fibre, sediments can make their way through the layer of stone over the years and clog your drain. Even when the filter fabric is present, it can clog itself with sediment and also lead to basement flooding.
It might be wise to provide ‘clean-outs’, to allow access for foundation inspection vis a camera snake. It should be noted as well that a French drain installed without use of a sump pump relies solely on gravity to drain any foundation water, so if the house isn’t on a hill or somewhat of an incline, finding a slope could be problematic. Also, maintaining an external French drain system can require some major and expensive exterior excavation.
Most internal French drains are only installed once the house is already built. Usually this is done as a result of a wet basement, or as a precaution when performing a basement finishing. When installing this type of drain, the perimeter of the basement floor is jackhammered to leave only the footing, and all cement is removed. A layer of stone is laid down while a perforated drain pipe is put on top of that. The water gets collected from the wall floor joints as it enters, and the pump removes that water and pumps it away from the foundation.
That being said, interior French drains are effective in waterproofing basements if they also use a sump pump. You should ensure that your sump pump was installed with a backup battery system with its proper sump liner to further prevent the pump from not having enough water and constantly turning on and off.
