If you want to waterproof your basement on your own, you can try waterproof paint, which is similar to ordinary wall paint, but thicker. One gallon of waterproof paint will cover 75 square feet, compared to 300 square feet for standard paint. The process is easy enough for a do-it-yourselfer, and it only costs about $37 per gallon. A full-scale exterior waterproofing solution, however, can cost anywhere from $10,000 to $15,000 depending on how much work needs to be done.

Exterior waterproofing

Exterior waterproofing is a way to seal water from seeping into your basement from the outside. It involves excavating the soil around your foundation walls and installing a waterproof membrane or coating on the exterior. These waterproof coatings also include drainage panels that help water flow away from your foundation walls and away from your home.

An exterior waterproofing system will stop most water from penetrating through the basement wall. However, it does not stop water from leaking through the basement floor or between the wall and the foundation. Clogged exterior drains can also allow water to seep into the basement and cause groundwater to accumulate around the foundation.

Exterior waterproofing is the most effective method of protecting your basement. However, it is also the most costly. The process involves excavating the soil away from the foundation walls, applying a waterproof coating, and installing drainage panels. This will help direct water away from the main structure. The process can cost several thousand dollars and will require a contractor to complete.

The process of applying exterior waterproofing involves cleaning the foundation walls and inspecting for structural cracks and voids. If any defects are found, they are repaired with a non-shrink specialized cement. This cement will fill in the cracks and voids. Another type of exterior waterproofing is a trowel-on rubber membrane. This membrane is designed to expand and contract with the foundation in the event of foundation movement. Another option is a drainage board that will act as a secondary barrier to the exterior waterproofing membrane.


Basement waterproofing is an important part of a home. It prevents the accumulation of water in the basement, which can cause molds, and may even weaken the foundation of a house. In addition, it protects the structural integrity of a home and can add value to the premises. Usually, basement waterproofing is done during the construction process of a house.

The method is a process that includes installing an interior footer drain and a sump pump. A sump pump is a device that collects underground water. The interior footer drain is wedged onto the floor or wall corner and directs it to a drainage point. A professional plumber can install a sump pump.

A sump pump is an essential piece of equipment in any basement waterproofing process. In addition to a sump pump, waterproofing materials like wall sealers and hollow baseboard molding will also help keep water out. American Dry Basement System, which offers comprehensive and affordable basement waterproofing services, can also help you choose the appropriate method.

A sump is the collection zone for groundwater under the floor of a home. The sump is usually located in a corner of the basement and is designed to collect and store groundwater. The sump is a cylindrical enclosure that houses a sump pump. These are typically circular in shape, about two to three feet deep, and feature drilled apertures for the exchange of groundwater. Additionally, they limit the entry of gravel into the sump.


The cost of basement waterproofing varies greatly, depending on the type of waterproofing required and the size of your basement. Most contractors quote on a square foot basis, but some work by the hour. Interior waterproofing costs between $3 and $12 per square foot. This includes materials and labor costs, and includes everything from excavating the basement floor to waterproofing the entire structure.

One type of waterproofing method involves applying a sheet of liquid waterproofing membrane over the interior walls. This process typically costs $3.53 to $5.25 per square foot, but it can be more expensive than standard waterproofing methods. The application of a thick layer of this material can keep water out of the basement, but it must be applied properly. This method requires extra care and extra preparation of the basement walls. Unlike solid epoxy, liquid epoxy must be solvent-based to effectively waterproof a basement.

When hiring a waterproofing contractor, make sure to get a written estimate. The estimate should include an evaluation of the problem, an explanation of the solution, and start and completion dates. In addition, be sure to ask for references to verify the work. Another good tip is to ask friends and neighbors for recommendations.

Another method that can help prevent water from penetrating walls is using an acrylic waterproofing paint. This type of paint is thicker than ordinary paint and is available from most home improvement stores. The cost of the paint can range from PS15 to PS20 per litre. If you’re concerned about water penetrating basement walls, acrylic waterproofing paint is a good solution that doesn’t require extensive excavation or modification of your home. However, this option is not permanent and can result in significant damage if the water is allowed to penetrate the walls.
