    J'ai used ces plans pour faire des rembardes d'escalier et elles sont parfaites ! Elles ont les bords arrondis et ont la même finition dessus et dessous. Elles méritent cependant d'être poncées car il reste une légère rugosité si on passe la main à contre sens de la coupe (ou du ponçage) d'origine. En même temps c'est normal, ce sont des lames de terrasse donc elles ne sont pas prévues pour accueillir des mains à la peau plus sensible… La découpe peut être laborieuse selon le matériel dont on dispose (bois très dense, pas facile à couper ) mais du coup qui devrait durer un certain nombre d'années, une fois protégé (moi j'ai simplement enduit d'huile de lin pour garder un maximum l'authenticité du bois...).

  2. Buyer (via Amazon) -

    Un peu cher mais super quality. Bords arrondis très propres. Used for refaire l'assise de siege de jardin. It is comporte très bien à la scie circulaire et à la defonceuse. Attention au visage, tendance à craquer. Faut y aller par étape ou faire un pre-trou.

    As described and pictured. Super fast delivery

    In short, we are delighted. Very clear recommendation. Very friendly advice and unproblematic purchase process.
    Our terrace was planned with the help of the terrace planner and we received a comprehensive offer very quickly. An extremely good calculation down to the last screw.
    Very nice decking boards (Cumaru)

  5. Tim Schoenfeld (via Google) -

    Here you not only get an offer, but also a precise, individually planned terrace according to all your wishes when you first contact us. Nothing was left unaddressed. The concept BETTERWOOD convinced me, as does my finished terrace. Many thanks again to the team and their performance.

    I used to avoid using tropical wood. Since I Betterwood discovered, I see things differently. I find the concept compelling. The delivered goods keep what was promised. My last project was a balcony terrace with Cumaru concealed decking boards. It's tedious, but worth it. The result is simply noble. The service is at Betterwood exemplary. You don't wait in a telephone queue, but speak immediately to someone who also has a clue about things and can give solid advice. And then everything is delivered on time. How to work.

  7. Andrea (via Amazon) -

    Ottimo legno duro. Difficile to wash

  8. Oliver Kohlmeier (via Google) -

    Uncomplicated and quick processing.
    The wood you bought is great. I would say 1A sorting and the local people are very nice.
    Again thank you very much

  9. Jörg Gayer (via Amazon) -

    Top quality for this price

  10. Fero Andersen (via Google) -

    I can only agree with the positive reviews. I laid Cumaru myself and I'm happy every day with the beautiful, pleasant-to-walk result. I have just added wooden steps to the terrace and balcony and once again received excellent advice. Warped wood or similar to this day (1 year later) none.

  11. Michael Wandlowsky (via Google) -

    About 1 year ago I had my terrace (40 m2) with Cumaru wood from the company Betterwood created.
    It was important to me that the wood is FSC certified, so I'm up Betterwood noticed on the internet.
    I got the first plans and the creation of a laying plan from Betterwood have it done. Since the result of the first laying plan did not quite meet my expectations, I found the optimal solution for me with Mr. Jaeger in several telephone calls.
    I have from Betterwood the decking boards, the substructure and the fastening material. I got the pedestals alone from another company there Betterwood was too expensive here.
    I am satisfied with the quality of the wood to date and would use it again Betterwood Kaufen.
    To date, only a few planks have warped slightly, which has no effect when walking on the terrace. Only the joint pattern is no longer what it used to be after laying in two places. Wood is a natural product that is subject to natural fluctuations.

    My conclusion: everything went well. Price, friendliness and cooperation was so good that I would buy here again. I still buy the oil for care here.

    Order Cumaru boards in sizes 5,18 m (31x), 4,88 m (7x) and 1,22 m (26x). Not a single one of the planks had any flaws, even under very critical inspection. The delivery took place in a telephone agreement with Mr. Jäger to an agreed time window of 4 hours. In summary, material quality, delivery reliability and also the expertise and friendliness of the employees, namely Mr Jäger, excellent!
