Answer:<\/p>\n\n\n\n
(i) The basic requirements for the material used for waterproof materials should be as follows:
(1) High adhesion.
(2) High extensibility.
(3) High tensile strength and tear strength.
(4) The non-intermittent tensile strength must be greater than 2mm.
(5) High tensile strength.
(6) Good weather resistance capability\u2014capable of withstanding heavy loads of earthwork or covering layers.
(7) It can prevent the tree roots from corroding the waterproofing material.
Considering all of the above, if I were to choose between its functionality and budget, the following would be my order of preference: (1) ultra-fast curing polyurethane from a well-known brand; (2) a tar-based PU from a well-known brand (for the tree holes and flowerbeds, I would add a layer of aluminum foil waterproof mat to prevent tree roots from penetrating); (3) pure hot-melt rubberized asphalt waterproofing adhesive imported from abroad; and (4) a hot-melt nonwoven fabric over top of it (because the majority of domestic rubberized asphalt manufacturers have insufficient purity and will often mix in cheap synthetic resins to replace the high-cost rubber).<\/p>\n\n\n\n
(ii) Pay attention to key construction details
(1) The key point in the process: waterproofing must be applied directly to the original structure of the floor surface; for some platforms, observation decks, waterfalls, fish ponds, staircases, double-story floors, high-low and irregular shapes, and sculptural and decorative elements, etc., secondary coating cannot be applied until after the waterproofing work is completed.
(2) The surrounding areas of the reinforcement holes and the through-hole patterns must be sealed with filling material to ensure proper bonding and reinforcement before the above-mentioned structural forms are installed. The selection of filling material must be carefully considered to ensure the proper adhesion of the waterproof material.
(3) Strict requirements for raw materials\u2014waste materials such as mud, lumps of mud, sludge, pits, mold residues, steel nails, etc. must be properly sorted.
(4) Before applying the flat waterproofing coating, all cracks in the floor surface must first be identified and treated using a sealing or insulating method.
(5) For all critical areas such as corner corners, construction seams, around drainage pipes, around water leakage points, around escape holes, and between pipes\u2026 etc., structural reinforcement must be considered and addressed first.<\/p>","protected":false},"excerpt":{"rendered":"
