Methods We Use To Waterproof The Outside Of Foundations

Waterproofing the exterior of a building involves adding a membrane or coating to the outside of the structure’s foundation walls. Drainage systems are installed to divert water away from the structure, and the foundation is excavated to fix any leaks or fractures. To avoid costly repairs and mold growth in the basement, external waterproofing must be done correctly. The steps for waterproofing the outside of a building are outlined below.


The outside waterproofing process begins with excavating the area surrounding the foundation walls so that they may be inspected and perhaps repaired. This facilitates the direct application of the waterproofing membrane or coating to the walls, preventing water from penetrating the structure. Grading and draining away from the structure can only be achieved with precise excavation.


In order to choose the best course of action for outside waterproofing, it is necessary to first clean and evaluate the foundation walls. The walls must be thoroughly cleaned of any dirt or debris that might impede the waterproofing process, and any evidence of damage or degradation, such as cracks or leaks, must be carefully examined. To make sure the walls are in excellent condition and protected against water infiltration, repairs can be undertaken before the waterproofing membrane or coating is applied.


Exterior waterproofing relies on the absence of leaks and fractures in the foundation walls, thus repair is a crucial step. Waterproofing coating should be used to effectively seal any leaks or cracks. If there are any holes in the walls or floors, we may fill them with hydraulic cement or another high-quality material. Making sure walls are solid enough to bear the weight of water and soil is crucial.


The key stage in outside waterproofing is, of course, waterproofing. To do this, you need to put a waterproof membrane or adequately cover the foundation walls. This coating acts as a waterproof barrier to prevent basement flooding and damage to surrounding walls. Carefully apply waterproofing compound to walls, making sure to cover every inch and create a tight seal.


Waterproofing the outside of a building requires drainage to divert water away from the walls of the foundation. A sump pump can be used to remove water from the basement, but other measures, such as weeping tiles or a French drain system, may also be taken. Water that pools around the foundation can cause structural damage and floods if proper drainage is not provided. It also aids in reducing hydrostatic pressure on the foundation walls, a common source of leaks and other structural damage.


After the waterproofing has been done and the drainage systems have been built, the next step is to backfill the soil that was dug around the foundation walls. To guarantee that water flows away from the structure, the soil must be graded and compacted correctly. As a result, the waterproofing system is better protected from water that may otherwise pool up against the foundation walls. A strong building foundation and a functional waterproofing system both depend on accurate backfilling.


Features like solar panels, efficient appliances, and rainwater collection systems help make these homes long-lasting and kind to the environment. This not only reduces power costs, but also aids in protecting the environment. Now a day's it seems like everyone is building an ADU or JADU onto their existing home.


ADUs and JADUs that are part of the AGING IN PLACE movement can be made to accommodate the needs of the elderly and the disabled. Incorporating accessibility features like grab bars, walk-in showers, and ramps for wheelchairs may make a building more welcoming and usable for people of varying physical abilities.

What we do for waterproofing for your roof and eaves

Waterproofing the roof and eaves of your home is a crucial step in preventing costly water damage. During building, our exterior waterproofing contractor make sure of the following details:

Roof Deck Waterproofing

We always use a waterproof membrane to encapsulate the roof deck prior to installing any roofing materials. No matter the environment or roof type, we always utilize the highest quality, longest-lasting membrane available.

Install Flashing

To prevent water from seeping into roof openings like vents and chimneys, we install flashing, a thin metal or plastic covering. We never risk a leak due to improper flashing installation.

Use Waterproof Underlayment

Protect your floors by laying down an underlayment that is impervious to water. Between the deck and the roofing materials, we install an underlayment that is both water and rot-proof. This is intended to provide as an additional barrier between the roof and rain. As a result, your roof will be protected from water for a longer period of time and its lifespan will be increased.

Install Eave Flashing

Eave flashing is installed where the eaves meet the roof. This is installed so that water cannot enter the attic space through the eaves and cause problems.

Install Gutters and Downspouts

To avoid water gathering on your roof and eaves, we set up gutters and downspouts. We'll check to see that the downspouts and gutters on your home are placed correctly and slanted away from the structure.
