Roof panel waterproof planning attention point.
Aug 10, 2018

The  waterproof layer of aerated concrete roof slab is not only the  waterproofing requirement of buildings, but also an important measure to  protect aerated concrete roof slabs. The coiling materials are still  commonly used at home and abroad. Due  to the narrow plate and the flat seam butt joint, the overall rigidity  is poor. Therefore, if the linoleum is directly laid on the roof panel,  the following points should be noted in the planning:
1.  The waterproof layer of aerated concrete roofing panel should have  better overall rigidity except that it should have better waterproof  function. The overall rigidity of the board must be well combined with  the main structure. Strengthen the union between the side seams. If  the gap is small and the general cement mortar is used for filling, the  metal sheet subjected to anti-rust treatment should be nailed between  the joints, or the mortar should be bonded.
2.  In the flat roof, generally no slope is found on the upper part of the  roof panel and the slope is determined by the structure. As  long as the pitch of the support is flat, it is ensured that the  surface of the plate is flat and it is easy to lay the linoleum.
3. Before the aerated concrete roof panel is made of linoleum, there is generally no gas barrier layer in the upper part. The  function of the gas barrier on the reinforced concrete roof is to  prevent the moisture in the room from penetrating into the insulation  through the reinforced concrete roof panel, which affects the heat  preservation effect. However, the aerated concrete roof panel itself is  the insulation material, so it is separated in the upper part. The gas layer has lost its meaning.
