Waterproofing Basement and Sources of water in a home

When it comes to waterproofing there is a great advantage to having a company such as ACCL Waterproofing that not only specializes in waterproofing, but also brings to the table a wide variety of solutions such as roofing, renovation, and basement construction.

Prevention and careful planning are all important in creating the proper protection against water damage.
There is a good deal of focus these days on enhancing the market value of a home, and as a result there is a great demand to enhance usable living space. Basement finishing and attic renovation are just two of the ways to create this extra space. However, both attics and basements present challenges as far as moisture intrusion goes.


The first step is to prevent water leakage by means of waterproofing efforts. Basement waterproofing is an obvious step to take, but roof or chimney repair, or even the installation of an entire waterproofing system for an extreme basement water problem.
That’s why it makes sense to deal with a multi-faceted company such as the ACCL Group, which takes care of renovations, plumbing, electrical, roofing as well as waterproofing.

Roof leakage is primarily due to two culprits — rainfall directly penetrating the roof and an accumulation of rain and/or snow on the roof that leaks over a period of time.
This is where an ACCL Roofer’s expertise can be of great help through careful inspection of the attic and rafter area.
Valley or wall flashing and especially chimney flashing may also need attention. A flat roof can accumulate standing water, another common cause of leakage.
It goes without saying that any leakage problems need to be eliminated before undertaking an attic renovation project to create more living space.

Although this problem is more rare, it’s worth having an ACCL professional check to make sure there is no exterior siding leakage problem (water leaking through the sheathing and wall framing, perhaps caused by a driving rainstorm).
This issue is easily handled by the proper installation of a structural waterproofing membrane over the exterior sheathing. The work is best performed during the initial construction process before exterior siding is installed.
Waterproofing membrane, also known as “house wrap,” is made of extremely strong plastic – the same material which goes into the manufacture of Kevlar bullet-proof vests.

House wrap products, such as Tyvek, are expensive, but well worth the investment. The benefits are that they offer a waterproof-barrier while at the same time still allowing the structure room to “breathe.”
Any complete and thorough waterproofing project must begin and end with the basement.
Accurate and careful planning in grading and placement of the home site prior to construction are all important. Due consideration needs to be given to both surface drainage and subsurface water tables.
Subsurface water levels should remain at least 10 feet below the foundation or basement floor at all times – even during the rainy season.
Basement water damage is a common occurrence that afflicts most Ontario homeowners at some time. Foundations may leak for many different reasons — from mould buildup or perhaps a congested weeping tile system, where the weeping tile can no longer flow due to a blockage of fragments, soil and/or tree roots.

Before you embark on any particular waterproofing journey, though, it’s a good idea to find out what the source of your problem is, so that you’ll know how to best attack the issue.
ACCL offers the highest standard in basement waterproofing expertise, methods and materials for your interior and exterior waterproofing, as well as concrete injection-sealing applications.
Basement moisture problems generally take one of three forms:

1, Condensation – inside air moisture content (which can be corrected by insulating water pipes, using de-humidifiers, and providing adequate ventilation).
2, Capillary action – when groundwater comes up through the foundation and slab. This generally occurs when the groundwater table is higher than the basement floor and foundation, and can be somewhat offset by use of a sump pump.
3, Leakage or intrusion – water leaking in through the basement walls and foundation, usually runoff from improper grading and drainage. This can be prevented by proper grading to aid water runoff and drainage away from the foundation, and by the application of a basement waterproofing product to the outer surfaces of the basement wall and foundation.
Installing a complete basement waterproofing system during the construction process is highly recommended. Basement wall waterproofing, foundation waterproofing, and concrete waterproofing can all be done as a retrofit, but considerable excavation may be necessary to expose surfaces for application of waterproofing material, and obviously this can become quite expensive.

The best-laid plan involves proper grading and drainage, application of a basement waterproofing product to seal exterior surfaces, and a sump pump system that can adequately handle fluctuating water tables at their peak levels.
Waiting until a problem is detected, carries with it some consequences, and considerable damage will probably already have been done by this stage, including the formation of mould or mildew on surfaces or in basement framing.
This may necessitate recruiting a water damage restoration contractor, who also provides mould remediation services.
Drainage is not waterproofing and should not be confused with waterproofing, or called waterproofing. Many companies that install interior drainage systems often refer to themselves as “waterproofing” companies, but, in fact, they don’t provide any type of waterproofing services at all.
In order to gain a competitive advantage they combine the interior system with something else, usually some sort of outside work.
The outside work generally benefits the customer very little, and just allows the company to drive up their price.
Drainage without proper foundation waterproofing will not prevent water from penetrating wall cracks. It will only prevent water from rising beneath the floor into the basement.
Most water control system companies rely on a stand-alone interior drainage system and a sump pump to control the water. They may call it something different, but pipe placed under the floor that leads to a pump is a water control system.
