Antique Burgundian slabs from France with an authentic look! De Opkamer is specialized in these exclusive floors that are also called Dalles de Bourgogne. These antique floors of old limestone are released from the demolition or renovation of old farms / churches / monasteries and are often 8 to 12 cm thick. We saw the top layer (first layer) at 3 cm thickness so that our tilers can place the floor perfectly.
