Abstract: A water leakage-proof apparatus aims to be firmly held between a shaft and a fixed surface to maintain water leakage-proof effect of the fixed surface and the surrounding of the shaft to prevent external water from flowing along the shaft into chinks around the shaft to form water leakage. The water leakage-proof apparatus includes a casing which has an orifice and an opening at one side. The water leakage-proof apparatus is coupled on the shaft through the orifice so that the opening covers the fixed surface. The water leakage-proof apparatus holds waterproof powder inside to achieve water leakage-proof effect.

Abstract: A waterproof heat-insulation construction method aims to spread a layer of waterproof heat-insulation powder through a waterproof heat-insulation module on a work surface to form waterproof and heat insulation effect thereof. The method comprises the steps of: first, anchoring at least one waterproof heat-insulation module which can be arranged on the work surface; then holding the waterproof heat-insulation powder in the waterproof heat-insulation module in contact with the work surface to form a waterproof heat-insulation layer. The invention also provides a corresponding waterproof heat-insulation module which can be constructed in a modular fashion to achieve waterproof and heat insulation effect for buildings.
