Interior Waterproofing

Interior waterproofing sub-floor drain system is an ideal remedy to all your water management needs. This unique and innovative design collects water from the two primary sources that are responsible for your basement water leakage. Sub-floor drain system collects water seepage from the walls and footer, along with any seepage through faults in the foundation.
The water is then channeled directly into a perforated pipe that goes among the problem wall. Unlike large holes, narrow slits throughout the main sections prevent large solids from entering the system.

This unique high flow design is capable of handling the most severe water problems. Sub-floor drain system then channels the water collected to a Sump Pump System to discharge the water away from the property. Sometimes, depending on the grade, we are able to discharge by gravity without using a Sump Pump.

All areas waterproofed by CGS Waterproofing & Foundations with our interior sub-floor drainage system are warranted to stay dry, once the area is waterproofed it is warranted for life. *Please see the contract for complete warranty details and exclusions.

Exterior Waterproofing

This is the external way to totally lock out water from your basement or foundation walls. It is the surefire way to relieve any amount of hydrostatic pressure pressing against your walls. One of the main reasons for foundation failures is due to constant water pressure.

Soil is heavy enough by itself but when water is added the weight can triple. Exterior waterproofing not only relieves the pressure but also keeps the basement walls from wicking water. This wicking will not only leave a substance called efflorescence but also raises humidity levels high enough to support mold growth.

Foundation Waterproofing

Important factors that indicate the need for foundation waterproofing.

1. Puddles of water in the basement

The appearance of pools of water in your basement can be an indication that your foundation is porous. Cracks on the foundation can allow water and moisture to enter the basement whenever it rains or when there is a plumbing leak.

2. Unpleasant smell in the basement

If there is an unexplained musty odor in your basement, there is a high chance that you are facing a mold problem. Mold grows in humid conditions and produces smelly compounds as it grows. The bad smell, therefore, indicates that your foundation is letting water or moisture into the basement.

3. Visible mold

Besides having a bad smell in your basement, you may also see patches of mold on the foundation and basement walls, on the basement floor, and on structures such as the ceiling and drywall. All these signs show that your basement is damp and should be waterproofed.

4. Signs of efflorescence

Efflorescence is the movement of salts through a porous material. If your foundation is porous, it will allow water from outside to pass through it. Salts dissolved in water will be deposited on your basement’s walls, and when they dry out, they form a crystalline or powdery substance. Sealing cracks in the foundation will eliminate this problem.

5. Dry rot

Wooden structures undergo dry rot when their moisture content exceeds 20%. If you notice signs of dry rot on wooden structures such as door frames, furniture, staircases and others within your basement, then your basement probably has a high level of moisture and your foundation needs waterproofing.

Entry of water and moisture into basements via the foundation is the reason why many basements are wet or damp. A wet or damp basement is not desired in your home because such an environment is conducive to the growth of mold. Mold poses a notable risk to your health and can also significant damage to your property.

Air that has a high moisture content also poses a bigger health risk in that in addition to promoting the growth of mold, it can also carry harmful pollutants such as mold spores, dust mites, nitrogen dioxide and many others for a prolonged period. Foundation waterproofing eliminates both moisture transpiration and water seepage through the basement walls.
Through foundation waterproofing, you can keep your basement dry and avoid the problems that are associated with damp or wet basements. For the best results, work with a professional foundation waterproofing service provider. Here are some crucial indicators that your home needs foundation waterproofing.

Mold Remediation

There is mold all around us at all times, it is a part of the natural environment and has a job to do. Mold’s job is to break down organic material.
The challenge starts when you have had excessive humidity or direct water intrusion, mold can and usually does begin to form.

That musty dank smell, in your basement or house should NOT smell like that and is one of the first signs that you have a mold issue.


Once it is visible to the naked eye, there are hundreds of thousands of spores.
Mold’s natural defense is to scatter its spores when it is disturbed. Once you get past a few feet of visible mold, you will need a professional to clean it up.

Please remember, BLEACH is not always the answer. Once the clean up is completed, the key is controlling the water and the humidity going forward.

If there is water, there could be mold
