Abstracts: The utility model relates to civil construction synthetic materials. The utility model is structurally provided with a geomembrane, an upper layer polyethylene foam plate, nonwoven fabric and a lower layer polyethylene foam plate. The upper surface of the upper layer polyethylene foam plate is composited together with the geomembrane arranged on the upper layer polyethylene foam plate. The lower surface of the upper layer polyethylene foam plate is connected together with the upper surface of the nonwoven fabric arranged below the upper layer polyethylene foam plate by needling. The undersurface of the nonwoven fabric is connected together with the upper surface of the lower layer polyethylene foam plate arranged below the nonwoven fabric. Compared with the prior art, because the utility model adopts two-layer polyethylene foam plate and one layer nonwoven fabric which is served as the insulating layer, the insulating effect is favorable. One layer of geomembrane can be served as the water-proofing materials, the waterproof effect is also favorable. Therefore, the utility model collects the waterproof function and the heat insulation function into integration, and the utility model is the civil construction synthetic material which is time-saving, labor-saving and economic.
