Waterproofing Materials For Retaining Walls – Waterproofing of foundations / supporting walls Waterproofing of the outside of the foundation is necessary for all buildings with basements. Foundations and supporting walls are constantly exposed to moisture. Foundation waterproofing or exterior basement waterproofing is necessary to avoid serious damage to the structure and major decorative damage to the interior spaces.
The MARISEAL SYSTEM® foundation and retaining wall waterproofing method provides simple integrated waterproofing, consisting of a highly resilient waterproofing membrane and a protective layer that loosens during installation, as well as custom insulation panels. choose.

How Much Does A Retaining Wall Cost To Install?
Usually, when the discussion turns to waterproof concrete, we think strictly about hydraulic structures. In fact, there are many other applications of concrete where permeability plays an important role in the performance picture. For example, almost any home basement is a job that requires waterproofing concrete. In fact, concrete should be impervious to almost any underground application. Even above ground – as well as garage floor slabs – concrete often has to withstand water or steam pressure.
The term waterproof is often used quite loosely. It is sometimes used in relation to the ability of concrete to withstand hydrostatic pressure. It sometimes refers to the ability to withstand the passage of steam. Of course, it is harder to achieve a concrete that successfully withstands liquid pressure than one that is resistant to the movement of a worrying amount of water vapor. Unless otherwise stated, we will cover hydrostatic pressure throughout this article.
A truly waterproof barrier requires a waterproof mass. Any substance, such as concrete, which is part of the curing process, the release of one or more of its components, e.g. evaporation or bleeding, has a disadvantage in achieving density. maximum. Bleeding leads to capillaries through the cement paste, and just as these channels allow water to escape from the concrete, they will then allow water to seep into and/or through the concrete.
Handling and mounting measures must be taken to prevent segregation. Concrete must not fall more than 6 feet free. Vibration is not used to move concrete horizontally. For high walls, concrete shall be placed in lifts that can access the lower parts of the formwork through openings in the sides of the formwork.

It has been mentioned that construction or cold joints should be avoided whenever possible. If this is not possible, care must be taken to minimize bleeding, which can weaken the concrete surface and hence its adhesion. If milky, the surface should be sanded or acid-abraded to form a solid high-strength concrete. When continuing to pour concrete, the surface must be clean, moist and free of dust.
Curing is very important to achieve the impermeability of concrete. It usually means the difference between a problematic leaky structure and a leaking structure. Concrete should not be exposed to hydrostatic pressure until the end of the curing period. Waterproof concrete must be allowed to dry for at least seven days, preferably 14 days or more. It is important to start treatment as soon as possible and continue without interruption.
Several processes have been used to improve watertightness after concrete has set. In general, these treatments are most effective when applied to the surface of a concrete member that is directly exposed to hydrostatic pressure, rather than to the interior surface. This often requires extra work, such as digging around the foundation, but often results are better if it is done. In some cases, this is the only means that can prevent or significantly prevent a leak.
A protective treatment is to cement a fabric film onto the outer surface of the hot asphalt concrete. When applying the membrane, it is important that the concrete is dry. The membrane will seal the porous concrete and must be flexible enough to bridge small cracks.

Another effective waterproofing treatment is the application of a grout containing metal aggregates and an oxidizing agent. When mixed with water, there is controlled expansion of the metal aggregates, resulting in a dense, crack-free barrier to water permeation. Another method involves the use of bentonite expanded clay, which can be applied in bulk as a bay where the base and wall of a building meet, or it can be sandwiched between cemented cardboard sheets or attached to the outside wall of the basement. Bentonite is said to remain active indefinitely and expand each time it gets wet to create a water repellent.
There is no space in this article to include all the treatments that have been developed for waterproofing concrete. It should be noted, however, that no treatment applied will be able to compensate for large accidental cracks and other problems arising from poor design and/or construction practices.
In summary, in order to achieve waterproof concrete, the following points should be considered: (1) using high-quality concrete components suitable for use needs; (2) prepare a mixture that provides sufficient strength and workability; (3) includes air contained; (4) attempt to divert water away from the structure; (5) design the structure correctly; especially in relation to the joints; (6) follow recommended handling and installation procedures; (7) thorough curing of concrete; and (8) if necessary, apply a high-quality waterproofing treatment to external walls exposed to steam or hydrostatic pressure.
Engineers provide you with the best solutions for waterproofing concrete structural and non-structural elements, including concrete pools, retaining walls, swimming pools, and more. We’ve had quite a few people ask us what’s the best product for building long-lasting retaining walls.
Leaking Block Retaining Walls
Our resident waterproofing expert – Johno – created the in-depth diagram below that shows the best way:
By using the steps above, you will ensure that your retaining wall is not weakened by excessive water retention behind the wall, thus extending the life of the wall.
So now you know HOW – want to know which product is best to use? Here are our recommendations:
