Supporting beams

Supporting beams

Portuguese houses often have supporting beams which are visible inside the rooms particularly in adegas and lojas (ground floor wine making rooms and animal shelters)

They can also be seen supporting a ceiling or roof ridge.

We are often asked to raise supporting beams because the original position was too low and the new owners who are refurbishing the house want to raise the height of the floor to provide a more habitable space with more light.

Raising these beams is not a job for the inexperienced or working alone because of the beams weight and the fact that they are built into the external walls. The danger here is that as a beam is moved perhaps slightly unevenly then the end of the beam may lever the central part of the wall upwards or outwards resulting in a potentially deadly accident. This is also a problem when putting new windows and doors into existing stone walls.
Safety is vital, your dream of living in Portugal would be severely dented with this scale of accident. Call in the professionals even if it’s just to carry out this type of work.

The next difficult thing is to re install and level up a piece of tree trunk that has sagged over time with the constant weight on it and is probably bent in another direction as well.

You may also have “rustic” concrete beams and pillars holding up floors, roofs, terraces and extensions.

Rustic in this case means of dubious quality and strength. This bog is not the place to go into the technicalities of concrete and concrete reinforcement. Suffice to say that we see more home-made nightmares that those constructed correctly. Remember that the person who erected that funny looking beam probably had no previous experience and was trying to save a few Escudos by doing it himself.

This is why we are tightly controlled when any reinforced concrete is used in a house build or refurbishment.
