During the repair, there may be a need to change the width and height of the doorway. This task is not the simplest, but with a competent approach, quite solved.
There are permissible expansion norms that are directly related to the type of wall of the house. The most common, concrete or brick walls allow you to create openings up to 2150 mm in height and up to 2100 mm in width. It is important that the tenants of apartments located on the lower floors, when expanding the doorway, must and additionally provide for its strengthening.
A common error is unauthorized deformation of the doorway, in which the uniformity of the load distribution on the wall as a whole is violated. Before starting work, it is necessary to contact the Bureau of Technical Inventory (BTI) with the relevant documents and get a permit in which permissible expansion standards will be prescribed.
The process of changing the size of the doorway begins with preparatory work. Firstly, from the room you need to remove furniture and other interior items, large-sized can be covered with plastic wrap. Secondly, the old door is dismantled and the door box is removed. The final stage of preparation is the marking of a new circuit of the opening.
There are two ways to increase the doorway. Professional repairmen use special disk tools with diamond spraying for cutting concrete and brick. Such equipment avoids cracks and fragments, and the edges will turn out even.
If the opening is expanded on its own, then through the perforator through the marking line the through holes are drilled, and then excess concrete or bricks are knocked down by a chipped hammer or a sledgehammer.
After the doorway is expanded, its edges must be carefully studied. Cracks detected and breakdowns should be eliminated using a screed.
