Structural Waterproofing

Cemplast Preservation are specialists in the waterproofing sector. We pride our self on our design and installation procedure toward waterproofing systems for existing underground structures (basements), and also new build underground projects.


In Chapter 5.4 of the NHBC standards for waterproofing it outlines that two systems working in conjunction with one another are essential to satisfy BS8102, this can take the shape of either Type A, B or C structural waterproofing outlined below.

While a household or property can feel secure and strong, one of the most common – yet hidden – problems are water damage. Water damage can be hidden until the problem becomes hugely expensive to repair and deal with. It can ruin the foundation of the building and make the whole enterprise feel far less safe to be around than beforehand. In a bid to help you avoid that problem and to avoid water damage before it sets in, structural waterproofing and flood protection can be the ideal solution. We offer the following waterproofing systems:

1. Type A waterproofing Systems

Type A waterproofing comprises various categories of ‘barrier’ system designed to be applied to the concrete or masonry structure. Triton supplies the following systems, along with a range of ancillary products.

• Fully Bonded Sheet Systems
• Liquid applied membranes
• Cementitious coatings/crystallization active systems
• Ancillaries

1. Type B waterproofing Systems

Type B protection is defined in BS 8102: 2009 as where the structure itself is constructed as an integral water resistant shell. The water tightness of a Type B construction is reliant upon using a concrete of low permeability and appropriate joint detailing.

1. Type C waterproofing Systems

Type C waterproofing is defined in BS 8102: 2009 as ‘drained protection’ which is achieved by the incorporation of a drained cavity within the basement structure. The basement wall must provide enough primary resistance to water ingress to ensure the cavity only accepts a controlled amount of water or dampness. Water is collected in the cavity between the external wall and an internal lining (cavity drain membrane) and diverted to a suitable drainage point.
Structural waterproofing is a solution used to help make sure that your building can be protected from any kind of water damage. Applied in a whole host of ways, various forms of waterproofing can be used to make your building resistant to damage, degradation or decay due to excess water intake. Some of the most common solutions that people will turn to for a reliable and safe waterproofing system includes:

• Barrier systems. These are the most common forms of structural waterproofing, and tend to be regularly used to help improve the strength of masonry or concrete. From liquid-applied membranes to ancillaries and cement coatings, many solutions can be implemented to add a barrier layer to help avoid any damage being done to the building itself. Helps to retain solidity and safety while more or less enveloping the building in a protective solution.

• Water Shells. As one of the most powerful solutions for waterproofing a building, creating an integral water resistant shell is one of the most reliable solutions. This allows for a low-permeability concrete to be used and then protected using a variety of styles to make that possible. From a waterproof chemical treatment being added into the concrete to make it more effective to a non-soluble crystalline formation that seals the concrete to avoid penetration, this helps to add structural integrity and improve the lifespan of the building itself.

• Drained Protection. Sometimes, the best solution for getting rid of water is to use a drained protection system. This utilizes a drained cavity within the basement, making sure that the walls offer excellent resistance to water excess, ensuring that they only hold a controlled and very specific volume of water. This then directs the water to the correct drainage point, allowing for blockages and excess water to be emptied without any problems.

Each of the services above can be used to help solidify the structural integrity of a building and to improve its value. Structural waterproofing is hugely valued in a building, and it helps to boost the overall value of a property as well as helping to add extra peace of mind about its structural safety. When you know that water problems are likely to be an issue due to the challenging British weather, investing in waterproof can make a hugely worthwhile expense.
