Rock wool composite board not only can keep warm, but also can effectively prevent the ground from moisture. Let's see how it plays the role of moisture regain.
Rock wool composite board is one of the good thermal insulation materials, mainly used for building exterior wall. But with its excellent waterproof and thermal insulation performance, most people will use it on the ground now to make the cement mortar and the floor as the interlayer, which plays the role of the moisture on the ground.
Construction method of rock wool composite board to prevent ground moisture
1. Construction of damp proof course. In a building, we have carried out the experiment of cushion damp proof, using 25cm rock wool composite plate cushion, coarse yellow sand or rubble filling surface joint, 6cm thick fine stone concrete, 1:2.5 cement mortar surface layer. After three years of observation, there is no phenomenon of tide return on the ground. After many engineering practice, it is proved that the cushion is effective. If possible, the insulation layer should be laid on the ground to achieve better effect.
2. Pay attention to the construction quality of filling layer. This is the first line of defense against moisture on the ground. The second damp proof layer is rock wool composite board. The filling of moisture-proof ground should be filled with clay (yellow) soil. If possible, 3:7 or 2:8 lime soil can be used. It is not suitable to tamp with construction waste or miscellaneous soil. The fill should be compacted in layers, and the thickness of each layer should be 20 mm. The filling of moisture-proof ground should not be constructed by loose filling and water immersion method, so as to avoid increasing the water content of foundation soil.
The use of rock wool composite board in the ground as a moisture-proof layer has many advantages, rock wool composite board is widely used in residential buildings, not only can play a role in thermal insulation. It used on the ground can also play a certain effect, if you often find that the ground will appear different degrees of moisture phenomenon, then a long time to use rock wool composite board to do the moisture-proof layer, because it is really effective to prevent the ground anti tide.
