What is a Cavity Drain System?
A cavity drain system is a type of waterproofing solution that is used to prevent water from entering a building through its walls or floors. Unlike traditional methods, such as tanking or external membrane systems, a cavity drain system works by channeling water away from the structure. This is achieved through a combination of drainage channels, membranes, and pumps that are installed within the structure of the property.
The system works by creating a barrier between the internal space and the external environment, which prevents moisture from entering. In the case of a basement, for example, the cavity drain system might involve laying drainage membranes on the floor and walls to collect any water that comes in contact with the building. The collected water is then directed towards a sump pump that removes it from the structure, ensuring that the interior remains dry and free from dampness.
How Does Cavity Drain Waterproofing Work?
Cavity drain waterproofing involves the installation of drainage membranes, which are designed to hold and channel water to a safe exit point. These membranes are typically made from high-quality plastic and have a studded surface that creates a gap between the membrane and the wall or floor. This gap allows water to flow freely behind the membrane, preventing it from reaching the surface of the walls or floors.
One of the most critical aspects of cavity drain waterproofing is its ability to handle water that may come in contact with the structure over time. The membranes are designed to work in a variety of conditions, including high water tables, heavy rainfall, and areas with poor drainage. In addition to the membranes, a network of drainage channels and a sump pump are also installed to ensure that any collected water is efficiently removed from the building. The system is highly effective because it does not rely on sealing the building from the outside but instead channels water in a way that minimizes the risk of damage.
Why Choose Cavity Drain Waterproofing?
There are several reasons why cavity drain waterproofing is an excellent choice for homeowners seeking a reliable and effective solution to water intrusion. First and foremost, it is a versatile system that can be applied to various parts of the property, including basements, cellars, and underground rooms. It works in both new builds and existing structures, making it an adaptable solution for a range of different scenarios.
Another significant advantage of cavity drain waterproofing is that it is less invasive than other traditional waterproofing methods. Since the system is installed inside the building, there is no need for external excavation or major disruption to the property. The installation process is relatively quick and can be completed without causing significant damage to the structure.
Additionally, cavity drain systems are long-lasting and durable. The materials used are designed to withstand the pressures of water and moisture over extended periods, making them a cost-effective solution for homeowners who want to protect their property without the need for frequent repairs or replacements.
