2nd-Generation Epoxy Resin Paving Joint Technology
GftK set the Global ‘State-of the-Art’ with their development of 2nd-Generation epoxy resin paving joint technology, which represents a significant evolution in characteristics and performance over all other materials, with many proven advantages, including:
- Completely dust-free mixing and application
- Optimised internal cohesion & extended flow (distance & time)
- Fully self-compacting, with no tooling required
- Non-staining, even on light coloured sandstone (No cement haze, epoxy bloom or so-called ‘temporary’ sheen)
- The only truly wet-weather jointing
- Optimum strength correlation (flexural tensile - compressive – emodulus) for performance in service
- No shrinkage or shrinkage cracking, even in variable width joints (unlike cement or air-drying compounds)
- Extended durability for a longer service life
Advantages for Contractors
GftK's advanced 2nd-generation, epoxy-based mortars have been designed to make paving joint installation Easier - Faster - Better. Overall, it is more cost effective and more efficient.
Easier – There are less limitations and far less delays due to the weather, plus the exceptional flow properties makes wet-slurry application easier, and there is no additional tooling and less surface cleaning required to complete the job, just rinse with a fine hose spray and brush-off – No haze or staining!
Faster – There is less work to do and fewer working steps, as the extended flow and optimised self-compaction eliminates the need for additional tooling or finishing, plus there is no additional staining, or haze removal works, so the final cleaning is faster. (This should probably be included in cost comparisons!).
The Unique Paving Jointing Technology – GftK’s 2nd-Generation, Epoxy Resin-based Paving Jointing Mortars.
Faster - Easier - Better!
Better – Importantly, though probably not currently considered enough by the guys on site, breathing and inhaling fine silica dust is extremely bad for you, even worse than cement (think silicosis, the clue is in the name!), even if the health problems do not come until many years later. The dust-free handling, mixing and application on site of these 2nd-Gen. products is ideal, and not just for the guys on site, but also for anyone nearby or alongside if working in public areas. Technically speaking – the lack of shrinkage and cracking issues is the other key advantage - There is no short- or long-term shrinkage and consequential cracking with these unique GftK products.
Advantages for Owners and Designers
The advantages of GftK’s 2nd-generation epoxy technology continue long after installation as the highly effective self-compacting characteristics, also ensure optimum joint filing and structure. This then hardens to be tough and resilient, with balanced mechanical properties that contribute directly to long-term performance and durability, specifically including:
- Excellent mechanical strengths correlation for loading and transfer
- Excellent thermal movement accommodation
- Enhanced resistance to environmental exposure
The result is a top performing paving joint system, designed not only for its ease and speed of installation with reduced limitations from wet weather, but for sustained performance and durability in service.
The Technology Explained
This 2nd-Generation epoxy paving jointing technology is unique and based on an exclusive, GftK developed, water-dispersed epoxy resin and hardener system, which is added to alluvial (glacially rounded) aggregates with the finest silica flour / dust fraction removed (no-fines). These are then graded to the optimized granulometry for joints from 5mm wide (i.e., GftK vdw 850 plus), or for the finer grade, from 3mm wide (i.e., GftK vdw 815 plus). The graded aggregates are then pre-coated with the special epoxy resin in another proprietary GftK process, and packaged for supply to site fully pre-batched, with the bottle of hardener, for ease of control and mixing.
These formulations are therefore easier to mix, completely dust-free, and they produce highly flowable, easy to use, wet-slurry applied jointing mortars that flow quickly and easily across the paved surfaces and into the joints, where they achieve optimum compaction without no additional tooling or finishing required.
Proven Performance
The following is a small selection of different paving projects completed with GftK's 2nd-Generation epoxy paving joint technology that has now been used extensively throughout the United Kingdom on projects of every scale. From residential patios and prestige landscaping projects to major commercial developments and public spaces for many cost-conscious Local Authorities, also looking to do the job right first time, and not have to pay for partial annual, or overall repointing every few years. These GftK systems have consistently demonstrated their ability to deliver with easy and reliable installation on site, followed by outstanding long-term performance for exceptional durability. We have compiled an extensive portfolio of Project Case Studies for both GftK vdw 850 and GftK vdw 815 which can also be searched by type of area and type of paving etc., in the Case Studies pages of this website here.

The Products
Both products utilise these same advanced epoxy resin, hardener and pre-coated aggregate technologies, with the aggregate grading tailored to suit different joint widths and applications.
GftK’s vdw 850plus
GftK vdw 850 plus is designed to be easier, faster and better, with no staining. It hardens quickly with no shrinkage cracking and is ideal for use everywhere that long-term performance and durability are required. It is fully resistant to high pressure water jet cleaning, as well as to weed growth and it eliminates damage by boring insects such as ants & miner bees.

GftK’s vdw 815plus
The same resin & aggregate technology, but with a finer aggregate grading for narrower joints from just 3mm wide, which makes GftK vdw 815plus particularly suitable for calibrated paving materials, including porcelain and other ceramic tile paving and accurately dimensioned paving slabs, as well as an innovative solution for more durable repointing of so-called ‘flexible’ unbound block paving.
View product detailsSelecting the Right Paving Jointing Materials Technology & Product
As outlined above and on the other pages of this website, there is no universal paving jointing materials technology and no universal paving jointing product. The right paving jointing for your project depends on the key criteria and your specific requirements.
We have produced a Paving Jointing Project Checklist, which is designed to help you identify and confirm all the relevant selection criteria for each project, in terms of the type and size of area, paving, joints, the site for installation and the required exposure and performance in service, durability, cleaning regime, plus the ease of closure and ease of eventual repointing.
We have also produced the GftK Paving Jointing Product Selection Guide that you can use this with the Checklist for each project, to ensure you consider all revenant criteria and select the most appropriate paving jointing solution. Always be sure to consider ALL the key criteria and parameters for your paving project, to make the right technical and commercial decisions based on ALL the requirements.
