Exterior Waterproofing Process

An exterior home waterproofing is a process in which a liquid asphalt-based product is applied thinly to the foundation. Since there is no rubber in the composition, waterproofing does not provide the ability to seal cracks. Waterproofing done during the construction phase of a home aims to meet only minimum building code standards and costs about $20 to $30 to cover 100 feet of any foundation. Homes built before 1980 lack moisture protection and waterproofing, causing their foundations to deteriorate. Although waterproofing protects against dampness, it cannot resist water infiltration.

Exterior waterproofing is a process that waterproofs and seals foundations by bridging cracks or defects caused by movement. Our primary waterproofing process uses RCC’s commercial product, Hydro Guard. It is applied in two coats and costs $200 to $250 to cover 20 feet. Using a commercial-grade waterproofing product allows RCC to guarantee 50 years of protection against dampness and water penetration, as opposed to waterproofing.

What Are The Most Common Problems?

The waterproofing walls from outside  has various potential causes, but the main ones are poor workmanship and the use of a membrane that is not fit for purpose or is not part of an entire system.

1. Problems from the upper levels

In multi-level buildings, problems associated with waterproofing failures can occur on the upper floors. On upper floors, waterproofing problems can arise from puddles of rainwater forming on the roof. Flat roofs, in particular, can collect excessive amounts of rainfall, leading to leaks and ultimately damaging the building structure. Poor workmanship on upper floors, such as faulty plumbing, can also lead to waterproofing failures.

 2. Substandard waterproofing building exterior work

Poor workmanship, including improper installation techniques, can lead to problems with leaks due to waterproofing failure. Hard-to-reach areas such as balconies and windows require professional work when applying to waterproof. Poor work also includes improper product specifications when the wrong product is used; and inadequate substrate preparation, which means poor preparation before the waterproofing membrane is applied.

3. Lack of maintenance

Ongoing maintenance in the form of inspections and remediation of waterproofing deficiencies can detect problems early and avoid serious problems such as concrete cancer. Even tiny leaks and cracks should be repaired immediately, as water damage can build up faster than expected and lead to serious problems. It is also advisable to maintain existing seals on windows, doors, and wall systems. Checking balconies, roofs, windows, cracks, and leaks as soon as you discover them and taking a proactive approach to maintenance minimizes the risk of them developing into serious problems.

4. Choosing the wrong waterproofing membrane

Be sure to choose a complete waterproofing system that includes a sheet metal membrane with all the accessories. It is also important to consider how flexible the membrane is to allow for building mobility, and how resistant it is to ultraviolet light, chemicals, harsh salt air, and in the case of green spaces, root penetration.

Main Steps For Exterior Basement Waterproofing

By following the seven steps for waterproofing the outside walls you will achieve the wanted result.

1. Check your walls for imperfections

The waterproofing on the exterior wall is only the best solution if the walls become damp as a result of rainwater or moisture. Before you look for waterproofing products in stores, it’s important to address any other causes of structural dampness. This could be anything from cracks in the bricks or condensation inside the wall to a burst water pipe. Once you eliminate the problem, you can apply waterproofing as a preventative measure.

2. Clean your gutters

The problem with clogged gutters is not only that they can overflow and run down the walls; they also trap rainwater, which gradually gets absorbed into the wood of the roof or fascia boards, which can lead to a number of problems, including wood rot, leaks, and mold. You can avoid all of this and keep your home healthy by simply cleaning your gutters twice a year.

3. Choose the right waterproofing product

There are a number of waterproofing outside of your house products available today that help homeowners protect their homes from outside moisture. Here are a few products you should consider: concrete waterproofing, which is a cement-like product that bonds firmly to concrete and masonry; it can be applied to any surface, including painted walls; a silicate-based concrete sealer that reacts with masonry and concrete components to form a waterproofing coating; this sealer can only be used on unsealed/unpainted walls; waterproofing paint, which is similar to acrylic wall paint, the only difference being that it provides better waterproofing characteristics. It is very important to choose a breathable composition, which is specifically designed to allow the walls to breathe and remove moisture. Prior to painting, the product can be applied. Look at the webpage for exterior waterproofing near me.

4. Use a waterproofing additive for stucco

Stucco can help improve aesthetics, make walls stronger outside waterproofing, and protect them from moisture intrusion. Although most exterior plasters have waterproofing properties, you can eliminate water infiltration problems and prevent them from reoccurring simply by adding a waterproofing additive to the plaster.

5. Prepare your walls for waterproofing

Regardless of which product you choose for external waterproofing the walls, you first need to get your walls in good condition. This means using a quality filler to repair cracks and fill holes. Allow the putty to dry optimally before sanding. Then sand away rough, uneven areas, remove dust by cleaning the surface with water and allow the walls to dry completely to ensure good adhesion between the waterproofing agent and the substrate.

6. Apply the waterproofing agent

A roller or brush can be used to apply the waterproofing agent. If a second coat is required, allow the first coat to dry completely and then apply a second coat. Use a sufficient amount of product to create an impervious barrier against moisture penetration.

7. Testing

Conducting a waterproofing test is very important to evaluate the effectiveness of products used to waterproof exterior walls. This test involves spraying water on the wall surface for several hours and holding the nozzle at a 30-degree angle. Your home will only pass the test if the moisture meter shows no moisture. Waterproofing exterior walls will not only prevent serious damage, but it will also increase the value of your home.
