How to prepare for the waterproofing of a house foundation

A damaged foundation can cause serious problems for your home and, therefore, for your well-being. If you want to proceed with the waterproofing of the foundation of your house, good preparation will greatly contribute to the success of your project. Your investment will maximize the health of your home by eliminating the presence of moisture and mold.

Here are some important steps to prepare for a foundation waterproofing project.

Recognizing the signs of water infiltration

When it comes to water infiltration, it is generally best to act early and perform repairs to the foundation in order to reduce expenses and avoid additional damage, which can quickly become significant in this type of breakage. It is therefore important to stay on the lookout for the various signs of water infiltration that may occur in your basement.

Routinely touring the exterior of your home will allow you to spot problem areas in your foundation. We recommend walking around your home while paying attention to more humid places or areas where water could tend to accumulate.

Watch carefully for signs of cracking in the plaster or in the cement of your foundation. Look at all the doors and windows, trying to notice if there are any visible signs of discoloration or other indicators of water or moisture accumulation. Condensation is also a sign of potential infiltration.

Also, check the interior of your home for signs of water infiltration such as:

  • Damp or mildew smell
  • Condensation in windows
  • Unusual warping of floors, walls or ceilings
  • Difficulty closing certain doors or windows
  • Presence of rings or efflorescence at the bottom of the concrete wall

Even if you are uncertain, if you notice signs that could indicate the presence of possible water infiltration in your basement, you should contact a company specializing in foundation inspections who can use the best techniques and give you a clear picture of the real situation.

Preparing for waterproofing

Once you have chosen your foundation expert and agreed on the work that will be done to waterproof the foundation of your home, you will need to prepare for this important project. This will contribute to the smooth running of the process when the work begins and also avoid wasting time.

Interior preparation

  1. You will need to clear your basement in order to leave the space necessary for your contractor to carry out the work. It would be wise to temporarily relocate your valuables as well as furniture that could interfere with the job of your foundation waterproofing specialists. They should inform you beforehand of the key areas they will have to access for the installation of the collection tank and the submersible pump.
  2. Replace burnt-out light bulbs to optimize lighting in the work area. Your foundation experts should have their own gear to light up, but good basic lighting will make a difference.
  3. If necessary, clean up larger debris and dust. Workers should have cleaning equipment, but an initial cleaning will allow them to be more effective as soon as they arrive.
  4. Anticipate the details and take the lead to ensure that access to your basement is as simple as possible on the day the repairs will take place.

Exterior preparation

  1. Your contractor will have designated the places to which they will require access. It is important to clear these areas for the work to be carried out. Relocate objects to locations that will not be used to pile excess soil.
  2. Move your favorite plants and shrubs which might be located close to the foundation. Little tip: Drop by the local nursery. Often, pots that have already been used are put in the trash! Exterior work requires excavation. If some plants are too close, they may have to be removed during operations. If the trunk of a tree is outside the excavation area, but its branches are in the work area, those branches might require to be cut.
  3. On the first working day, make sure to leave your entrance clear to facilitate access for the contractor’s team. Also, take into consideration the trucks that will bring the machinery. They will have to park in the street and will take care of the storage of materials (excavation soil or stone for the new French drain, asphalt or concrete).
  4. Sometimes, a street occupancy permit is required when you need to park equipment or put material on the street. Charges may then be added.
  5. The preparation work you have decided to do in order to save some costs must have been carried out before the arrival of the excavator. These could include removing and storing paving stones, wooden porches, etc.
  6. Taking a video before the start of the work can greatly help in avoiding any misunderstandings at the end of the job, especially for any breakage that may occur. Keep in mind that, as the saying goes, “you have to break some eggs to make an omelet”. This means that some breakage will have to be part of the normal collateral damage. It should also be taken into account that the mechanical shovel weighs between 8,000 and 10,000 pounds, which means there is a possibility of torn grass, slight demarcations on the asphalt, etc.
