Description

Technical Field

[0001] This invention relates to the field of building waterproofing engineering, specifically a multi-layer waterproofing construction method for bathrooms. Background Technology

[0002] In daily life, the bathroom is one of the areas with the highest water usage, and it's easy for water to accumulate and leak if not handled carefully. Therefore, waterproofing in the bathroom cannot be ignored. Bathrooms use a relatively high amount of water, and if the floor is frequently wet, water can seep into the walls through cracks or into the floor grout lines, causing leaks. Furthermore, compared to other rooms in the house, bathrooms have more and more complex facilities, so if leaks occur, it may be necessary to remove floor tiles or walls and repair the corresponding water pipes, which requires a significant amount of work. In addition, bathroom leaks can affect downstairs neighbors, affecting neighborly relations and causing unnecessary financial losses for the homeowner. In conclusion, bathroom waterproofing requires a safe and long-lasting solution.

[0003] However, traditional bathroom waterproofing designs often consist of two layers of polymer coatings or films, which have certain design flaws. They are frequently damaged when in contact with sharp objects, losing their waterproofing function. Furthermore, they are prone to aging and difficult to repair, making it difficult to meet the demands of modern families for a high-quality life. Therefore, there is an urgent need to improve the construction process to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a multi-layer waterproofing construction method for bathrooms, which addresses the current state of the technology by using polyurea waterproofing, waterproof penetrating agent, and plastic layer for multiple waterproofing processes. The construction method is convenient and widely applicable, and can be promoted and used on a large scale. In addition, the construction method of this invention can save construction costs and maintain the waterproofing of the bathroom for a long time, avoiding subsequent problems.

[0005] The technical solution adopted by this invention to solve the above-mentioned technical problems is as follows: a multi-layer waterproofing construction method for bathrooms, characterized in that the bathroom is treated during the waterproofing process through preset operations, specifically including the following steps:

[0006] S1: When the height of the drop slab on the bathroom surface exceeds the set value, extruded polystyrene board is laid in the drop slab area, and lightweight aggregate concrete is used to fill the drop slab area. Then, extruded polystyrene board is laid on the lightweight aggregate concrete to form the filling material for the drop slab area.

[0007] S2: Use double-sided butyl tape to stick the PE plastic board on the filler in the lowered area and compact it. Use a spray gun to heat melt the junction of the bathroom wall corner and the floor to create a rounded corner to form a waterproof layer.

[0008] S3: The tiles are glued to the waterproof layer with an adhesive, and the hollow areas between the tiles and the waterproof layer are filled and sealed with a waterproof penetrating agent.

[0009] S4: When the grouting is complete, use transparent polyurea waterproof adhesive to seal the tile gaps.

[0010] Furthermore, after the waterproof layer is formed in step S2, a water tightness test is conducted to locate any leaks in the waterproof layer.

[0011] Furthermore, the leak is repaired by waterproofing treatment until the waterproof layer passes the water tightness test.

[0012] Furthermore, when the waterproof layer passes the water tightness test, an interface agent is applied to the waterproof layer.

[0013] Furthermore, when the interface agent dries, a leveling layer is made in the bathroom using cement mortar.

[0014] Furthermore, prior to step S1, a pre-designed waterproofing preparation process is performed on the bathroom, specifically including the following steps:

[0015] S01: Cleaning up trash on the bathroom floor using cleaning tools;

[0016] S02: Applying a bonding agent to the surface of the bathroom;

[0017] S03: The leveling layer of the bathroom is made by cement mortar. When the strength of the leveling layer reaches the set value, the leveling layer is applied by polymer waterproof coating.

[0018] S04: After the polymer waterproof coating dries, a water tightness test is conducted on the leveling layer to detect leaks until the leaks in the leveling layer pass the water tightness test.

[0019] Furthermore, the thickness of the polymer waterproof coating is 2 mm.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] (1) The multi-layer waterproofing construction method for bathroom described in this invention uses multiple waterproofing methods such as polyurea waterproofing, waterproof penetrating agent, and plastic layer to prevent water from seeping into other parts. Even if water seepage occurs, there is still a polymer coating waterproofing layer for protection.

[0022] (2) Using extruded polystyrene board as a protective layer for the polymer waterproof layer is more effective and also has a heat insulation function;

[0023] (3) The overall construction method is relatively simple and the cost is low, making it suitable for family bathrooms. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] To enhance the waterproofing of the bathroom, such as Figures 1 to 3 As shown, this embodiment provides a multi-layer waterproofing construction method for bathrooms, characterized by treating the bathroom during the waterproofing process through preset operations, specifically including the following steps:

[0029] S1: When the height of the drop slab on the bathroom surface exceeds the set value, extruded polystyrene board is laid in the drop slab area, and lightweight aggregate concrete is used to fill the drop slab area. Then, extruded polystyrene board is laid on the lightweight aggregate concrete to form the filling material for the drop slab area.

[0030] S2: Use double-sided butyl tape to stick the PE plastic board on the filler in the lowered area and compact it. Use a spray gun to heat melt the junction of the bathroom wall corner and the floor to create a rounded corner to form a waterproof layer.

[0031] S3: The tiles are glued to the waterproof layer with an adhesive, and the hollow areas between the tiles and the waterproof layer are filled and sealed with a waterproof penetrating agent.

[0032] S4: When the grouting is complete, use transparent polyurea waterproof adhesive to seal the tile gaps.

[0033] Before carrying out waterproofing work in the bathroom, a pre-treatment process for waterproofing should be performed according to a pre-defined procedure, which includes the following steps:

[0034] S01: Cleaning up trash on the bathroom floor using cleaning tools;

[0035] S02: Applying a bonding agent to the surface of the bathroom;

[0036] S03: The leveling layer of the bathroom is made by cement mortar. When the strength of the leveling layer reaches the set value, the leveling layer is applied by polymer waterproof coating.

[0037] S04: After the polymer waterproof coating dries, a water tightness test is conducted on the leveling layer to detect leaks. When the leaks in the leveling layer pass the water tightness test, the leveling layer forms a waterproof layer.

[0038] During cleaning, use cleaning tools to remove debris from the bathroom floor slab. Ensure all debris and contaminants are removed to guarantee the quality of subsequent construction. Thoroughly remove dirt and dust, ensuring a clean and unobstructed surface. Next, apply a bonding agent to the bathroom floor and walls. When applying the bonding agent, choose a suitable material, ensuring even application and clear edges to enhance adhesion between the base layer and the surface, improving the overall waterproofing effect. During construction, apply the coating using a brush or roller, ensuring the entire bathroom floor slab surface is covered. A 15mm thick cement mortar layer is then created using a 1:3 ratio. Mix the cement and mortar according to the ratio, ensuring even mixing, and apply this mixture to the floor slab to ensure a smooth surface. Once the leveling layer reaches the set strength, apply a 2mm thick polymer waterproof coating. During application, ensure the coating is applied evenly to guarantee waterproofing. Pay attention to the thickness and uniformity of the coating, as well as its tight adhesion to the bathroom walls. After the polymer waterproof coating layer is completely dry, conduct a water tightness test to check for leaks. Repair any areas that fail the test until all areas pass the water tightness test, ensuring overall waterproofing and forming a waterproof layer.

[0039] Furthermore, extruded polystyrene (XPS) boards are laid on the bathroom waterproofing layer to form a filler for the lowered slab area. A 30mm thick XPS board is laid on the surface of the waterproofing layer, serving as a waterproofing protective layer. If the lowered slab height in the bathroom exceeds the set value, an XPS board of a certain thickness is first laid on the lowered slab area, and then lightweight aggregate concrete is used to fill the lowered slab area to level the height difference, making the bathroom surface flat and increasing the stability and load-bearing capacity of the floor, enabling it to withstand the loads of daily use. Finally, an XPS board of a certain thickness is laid on top of the lightweight aggregate concrete to form an XPS layer. The sandwich structure consists of three layers: polystyrene board, lightweight aggregate concrete, and extruded polystyrene board. The thickness of each layer is adjusted according to the height of the lowered slab. While providing waterproofing, each layer also serves as a filler in the lowered slab area. During the installation of the extruded polystyrene board, it is necessary to lay it according to the design requirements and the height of the lowered slab to ensure the integrity and coverage of the board. If the bathroom has a significant lowered slab height, lightweight aggregate concrete needs to be filled on top of the extruded polystyrene board to ensure the stability of the overall structure and waterproofing effect. This improves the waterproofing performance of the bathroom surface, effectively addresses the issue of the lowered slab, and enhances the overall project quality.

[0040] Next, a 3mm thick PE plastic sheet is adhered to the filler material using double-sided butyl tape and compacted. The overlap width should be no less than 75mm. A heat-sealing process is then used to create rounded corners at the junctions of the bathroom walls and floor, forming a waterproof layer. When laying the PE plastic sheet, it is crucial to select an appropriate thickness and material, and use double-sided butyl tape for adhesion to ensure a firm and tight seal. During joint treatment, ensure an overlap width of no less than 75mm, and use a heat-sealing process at the corners where the bathroom floor meets the walls to create rounded corners, ensuring integrity and waterproofing effectiveness. After completion, conduct another water tightness test to ensure the waterproof effect of the PE plastic board. If any part fails the test, it needs to be repaired in time until the water tightness test is passed to ensure the overall waterproof effect and effectively prevent water from penetrating at the corners, thus improving the waterproof effect. At the junction of the upper part of the PE plastic board and the wall, a polymer waterproof coating layer is used for bonding. The polymer waterproof coating layer covers a height of at least 1500mm, thereby enhancing the waterproof effect of the wall and ensuring a good seal at the junction with the PE plastic board.

[0041] Furthermore, after the water tightness test is completed, an interface agent is applied again to enhance the adhesion between layers and ensure the stability of the overall structure. A leveling layer is then made using cement mortar of the same proportion to ensure a smooth surface, which is essential for the quality of the subsequent finishing layer. The two leveling layers are applied to ensure construction quality, improve the flatness, strength, and aesthetics of the floor and walls, and meet the requirements of laying and technical standards.

[0042] Furthermore, the tiles are then adhered to the waterproof layer using an adhesive, and any hollow areas between the tiles and the waterproof layer are filled and sealed using a waterproof penetrating agent. This repairs the hollow areas of the tiles while preventing water seepage, thus providing a certain degree of waterproofing. After five days of construction and once the waterproof penetrating agent has fully cured, the tile gaps are then sealed with a grout sealant to ensure the overall integrity of the bathroom's waterproofing effect.

[0043] Furthermore, after the grouting in the bathroom is completed and has been cured for a week, transparent polyurea waterproof adhesive is used to seal the gaps between the tiles, preventing water from seeping in through the gaps, thus completing the multi-layer waterproofing construction of the bathroom.

[0044] In summary, the multi-layer waterproofing construction method for bathrooms described in this invention involves laying extruded polystyrene (XPS) boards in the lowered area when the surface drop exceeds a set value. Lightweight aggregate concrete is then used to fill this area, followed by another layer of XPS boards laid on top of the lightweight aggregate concrete. This forms a sandwich layer of XPS boards, lightweight aggregate concrete, and XPS boards in the lowered area. PE plastic sheets are then adhered to the filler using double-sided butyl tape and compacted. Finally, a spray gun is used to heat-melt the corners where the bathroom walls meet the floor, creating rounded corners to form a waterproof layer. Finally, adhesive... The adhesive is used to bond the tiles to the waterproof layer, and a waterproof penetrating agent is used to fill and seal any hollow areas between the tiles and the waterproof layer. After the grouting is completed, transparent polyurea waterproof adhesive is used to seal the tile gaps. The entire construction uses multiple layers of waterproofing, including polyurea waterproofing, waterproof penetrating agent, and a plastic layer, to prevent water from seeping into other areas. Even if water seepage occurs, a polymer coating waterproof layer provides protection, and extruded polystyrene board is used as a protective layer for the polymer waterproof layer, resulting in better performance and insulation. The overall construction method is relatively simple and low-cost, making it suitable for home bathrooms and highly adaptable.
