Hello everyone,
we had a concrete staircase (cast-in-place concrete) poured in our new single-family house. Unfortunately, the construction planner failed to measure the staircase after the formwork was removed. Yesterday, a stair builder was on site to take measurements and saw that the stair steps have a maximum height difference of about 2.5 cm. This definitely needs to be repaired. He recommended leveling these heights with OSB boards. Later, a wooden step is supposed to be glued on as the step covering.
Here are my questions to you: The staircase was poured in August last year. Does it still have residual moisture? Or does the concrete staircase need to be treated with an impregnation/sealing coat? I am afraid that the wooden steps might swell later, etc.
Furthermore, I am surprised that the stair builder wants to realize the height adjustment with OSB boards. Ultimately, that would be an additional layer that has to be glued. Wouldn’t it be more sensible to level the step height with concrete?
Thank you very much in advance
Best regards Julian
