What is Basement tanking?

Ever thought about transforming that damp, unused basement into a functional space? Basement tanking might just be the solution we need. This waterproofing technique ensures our basements stay dry and mould-free, making them perfect for anything from a cosy living area to a practical storage room.

In this article, we’ll go through what basement tanking involves, why it’s essential, and how it can add value to our homes. Whether we’re dealing with minor damp or significant water ingress, this guide to tanking can help us make informed decisions and protect our property.

Understanding Basement Tanking

Basement tanking involves applying a waterproofing system to basement or cellar walls and floors, making them watertight. This is essential for properties across Cambridgeshire and beyond, where high groundwater levels can lead to damp problems. By tanking a cellar or basement, we can prevent water ingress and transform these underused spaces into dry, habitable areas.

The Difference Between Basement Tanking and Basement Waterproofing

This is a question that our team of basement waterproofing specialists get asked on a regular basis. It is something that is definitely worth knowing while you’re researching how to make your basement dry.

Basement tanking is the application of a waterproof coating or membrane to the basement floors and walls to inhibit water ingress. Basement waterproofing refers to all types of waterproofing systems including tanking and cavity drain systems.

Basement Tanking Systems

There are several basement waterproofing methods. ‘Type A’ waterproofing uses a tanking slurry or membrane applied to the internal or external surfaces, creating a waterproof barrier. ‘Type C’ waterproofing involves a cavity drain system that collects and channels water away from the basement walls. Both methods aim to stop water and ensure a dry space and which system your basement needs depends entirely on your building.

Type A – Basement Tanking Slurry System

Commonly, basement tanking refers to the process of applying a coat of waterproof cement or slurry. This helps to hold back hydrostatic pressure from the external walls of the basement.

This system of basement tanking is referred to as Type A waterproofing.

Type C – Cavity Drain Membrane System

However, basement waterproofing refers to ensuring the basement is watertight which means managing any water entering the basement. If water continues to enter the cellar then an installation of a cavity drain system (Type C) is required.

A Type C system directs the water away from the property through drainage or a sump pump.

Key Components To Tanking Solutions

Membrane Tanking

Membrane tanking uses a waterproof membrane applied to basement walls and floors. This system provides protection against water ingress, making basements watertight. These membranes, often made from bitumen or HDPE (High-Density Polyethylene), prevent water from penetrating the structure. It’s crucial for areas with high groundwater levels, such as Cambridgeshire.

Cementitious Tanking

Cementitious tanking involves applying a specialised cement-based tanking slurry directly to the substrate. It’s ideal for basements and cellars with concrete walls and floors. By forming a solid waterproof coating, this method effectively stops water ingress. Common in older properties, cementitious tanking can adapt to different surfaces, providing durable waterproofing.

Cavity Drainage Systems

Cavity drainage systems offer an alternative form of waterproofing by managing water ingress rather than preventing it. A cavity drain system channels water into a drainage system, keeping the basement dry. This system involves installing a waterproof membrane with a network of drainage channels and a sump pump, ensuring that water is safely removed from the building. Popular in areas like Cambridgeshire, these systems provide reliable protection against moisture and condensation.

These variations of basement tanking systems cater to different needs, ensuring basements remain dry and habitable. For professional guidance on the best method for your property, consult the NHBC Standards on basement waterproofing.

Benefits Of Basement Tanking

Proper basement tanking not only prevents damp walls and related issues but also adds value to our property. By employing a trusted waterproofing system, we can convert unused spaces into comfortable living areas, storage, or even home offices, suited to the needs of Cambridgeshire homeowners.

Maintaining a tanked basement or cellar prevents future damp problems, ensuring a long-lasting dry space. By understanding the nuances of tanking and waterproofing, we can make informed decisions tailored to our specific requirements. For more detailed guidance, you may refer to NHBC Standards, which cover best practices in basement waterproofing.

Protection Against Water Damage

Basement tanking effectively prevents water ingress, reducing the risk of damp walls and mould. By applying a tanking slurry or membrane to the walls and floor, we create a watertight barrier that keeps water out and maintains a dry basement.

Increased Property Value

A professionally tanked basement or cellar enhances property value. Transforming an unused, damp area into a habitable dry space increases overall property appeal and market value, making our investment worthwhile. According to the NHBC Standards, proper tanking solutions ensure long-term protection and value retention.

Steps Involved In Basement Tanking

The first step in basement tanking work is to assess the brickwork and identify any existing moisture issues, including water pressure from the surrounding soil. From this investigation, a strategy that involves a water management system that effectively redirects water away from the basement is developed.

As we’ve mentioned previously, to waterproof your basement, various approaches can be taken, such as type A and type C waterproofing. Understanding what’s the difference between these methods is essential, as type A involves external waterproofing solutions, while type C is more about internal measures. The process often includes applying tanking coatings or installing membranes that help prevent vapour from penetrating interior walls.

After preparing the surface of the walls and making the basement watertight the waterproofing specialist will decide on how to remove the excess moisture from the building. The last step is to make good the walls. This is usually done with plasterboard and skimmed with plaster dependent on the end use of the basement and if there has been a basement conversion.

Costs And Considerations

When considering your options to waterproof your basement in Cambridgeshire, it’s essential to understand the costs and considerations involved. We need to look at material and labour costs to decide the project’s feasibility.

Material Costs

Material costs for basement tanking vary depending on the system used. For example, tanking slurry costs between £20-£50 per bag, while waterproof membranes cost around £10-£20 per square metre. Additional costs include drainage systems, which can range from £100-£300. Using higher-quality materials results in more effective waterproofing.

Labour Costs

Labour costs depend on the job’s complexity and the professional’s experience. Specialists may charge £200-£400 per day, with the total project costing anywhere from £2,000 to £10,000, depending on the basement’s size and the work required. Hiring experienced professionals ensures that the basement walls and floors are properly treated, reducing future damp problems.
