The invention discloses a non-asphaltic base construction method for a pre-paving type high-molecular self-adhesive film waterproofing membrane for a basement floor. The method comprises the following steps of (1) repairing of a protection wall, (2) treatment of a foundation layer, (3) paving of the membrane, (4) bundling of reinforced bars and (5) concrete pouring. Compared with a traditional method, the construction procedures of the pre-paving type high-molecular waterproofing membrane are simple, requirements for treatment of the foundation layer are not high, primer treatment, a leveling layer and a protection layer are not required, the project efficiency is greatly improved, and the construction period is shortened; construction operation is convenient and flexible, the construction process is easy to master, pertinence is high, and the working efficiency is high; and the requirements for construction devices are low, proportioning can be conducted in advance, unnecessary waste during construction is reduced, and the economic benefits are remarkable. The pre-paving type high-molecular waterproofing membrane is low in weight is low and reliable in butt joint, has high tensile strength and good waterproof effect compared with a traditional waterproof membrane, can obviously improve the effect of a waterproof project, and reduces the expenses of later maintenance; and as no primer operation or fire operation exists during construction, potential safety hazards are eliminated, resources are saved, and the environment friendliness is improved.
