Finger-jointed terrace wood
Finger-jointing is a tried-and-tested wood connection in timber construction, through which individual pieces of solid wood are put together to form a longer piece of decking wood. Wedge-shaped prongs on the ends of the pieces of wood interlock and are weatherproof glued together. This can be seen on the surface of the plank, but fades into the background with weathering and the formation of the patina.
Finger-jointing offers various advantages: the wood is less prone to warping and the tree trunk can be used more efficiently, which makes the product particularly sustainable and usually also cheaper.

Everything great! Super team and best truth!

Very friendly and competent advice! Timely delivery, just as promised. Super decking boards (Cumaru) and substructure. The floorboards were very straight and exactly 120 mm wide. The substructure and floorboards were always a bit longer (UK, for example, 5 cm) than indicated.
All in all I am completely satisfied. Highly recommended !!

Thanks to the really easy terrace planner, the very friendly advice and the good feeling of not having harmed the environment, an absolute A+ with asterisks. Since I bought Cumaru and the terrace will be fun for 1 years, the price is more than justified. Also for amateur builders, how strongly recommended….

First the positives: the goods were available very quickly and the planking was almost perfect: we didn't have to sort out a single board. Unfortunately, that didn't apply to the UK, where two beams were so bent that we had to dismantle again. (We could have noticed beforehand) What really annoyed me personally, however, was the delivery itself: 220 euros is no small matter, especially considering that you have to unload yourself. But I would have gladly paid for it if the delivery had been as sustainable as the wood... But the opposite was the case: the driver, who only spoke Russian/Polish (a very nice guy by the way) came from POLAND at approx 40 km away from us to load the goods and bring them to us (and then drive back to Poland) There was nothing on the truck except our goods. This is by no means ecological and therefore the price for the delivery was exorbitant in my opinion. I'd be happy to pay a higher price, but not when such ecological madness is being pursued. Nevertheless: the wood Cumaru) is great.

I highly recommend this blade and this company. Mr. Jaeger was a very good advisor to us and patiently answered all of our questions. All agreements were kept. We are not very good craftsmen and despite the great help from Mr. Jaeger we got a very nice terrace. Thank you Mr Jaeger
