With a long background in structural waterproofing, Delta’s Director, Christopher Burbridge, tells us all about one of his favourite products.
As much as I love structural waterproofing (and trust, me I really love it), Koster products really are a place to invest when it comes to your project needs. I'm not saying you must drop half your budget on a lot of products, but you do have to invest time, research and yes, perhaps a little cash, when it comes to creating a robust solution.
What is Koster KB-Flex 200?
A WOW product and one that never fails to impress me is Koster KB-Flex 200. I absolutely love how Koster KB-Flex 200 can instantaneously stop water in its tracks. Within seconds KB-Flex 200 can solve massive problems, turning into an incredibly easy solution. It’s a great “impact” product.
What does it do?
Koster KB-Flex 200 is a permanent plastic sealing compound ideal for sealing pipe and cable penetrations, cavities and for custom detail waterproofing solutions against moisture and pressurised water.
Prior to application, the Koster KB-Flex 200 cartridges are laid into warm water and heated to approximately +30°C. This ensures that the material has the optimal consistency for application. The application area flanks must be thoroughly cleaned from the inside so that they are free of dust, sand and other loose particles.
Koster KB-Flex 200 must be dimensioned so that the ratio of the width (w) to the diameter (d) of the installed material is not below 1.5:1. The maximum diameter of the waterproofing is 300mm. Before applying Koster KB-Flex 200, a backing is installed in the penetration at a depth of 10cm using a common 2C PU foam. The Koster KB-Flex 200 cartridge is then placed in the gun and the material is pressed into the penetration from back to front utilising the nozzle so that the resulting layer thickness is at least 8cm.
Locking down a structure
Delta has a famous phrase - “locking down a structure”. When we use this in a technical term, we are looking to stop any active water/leaks percolating through the structure at that time and/or to protect areas that are weak points such as service penetrations, which have the potential to leak. We need to ensure these areas are sealed prior to the application of the waterproofing system.
KB-Flex 200 makes the job of “locking down a structure” an incredibly easy one.
Koster KB-Flex 200 can be used anywhere: existing structures, basements, swimming pools, new projects.
The product is ideal because:
- It doesn’t require ongoing maintenance
- It can instantly stop flowing water
- It doesn’t dry out and remains permanently mouldable
- It adheres extremely well to dry and moist substates
- It's great for sealing pipe and cable penetrations along with leak sealing and gap filling and sealing
- It can be applied to dry, moist or wet substrates
- It has an immediate functionality
- It’s suitable for both positive and negative waterproofing
