Waterproofing work in the basement is an important component of the basement project, and different project requirements are suitable for different basement waterproofing construction programmes. The following is an introductory waterproofing programme in the basement。
I. Overview of the project
This programme applies to waterproofing works for new or established basement structures. It is designed to address leakage, damp problems caused by groundwater infiltration, structural cracks, cavity, etc., and to ensure long-term drying, structural safety and use of basements。

Principles for water protection design
A combination of “prevent, drain, intercept and block”: based on structural self-waterproofing, accompanied by enhanced soft waterproofing, supported by drainage measures。
It's a soft patch: the floor, the side wall, a softly integrated multi-track defense。
Focused treatment: specific waterproof sealing treatment of deformation, construction stitches, refilling bands, pens (boxes), pre-burials, stakes, etc。
Material matching: select waterproofing material that is highly performanceable, durable, environmentally friendly and compatible with grass-roots characteristics。
Main construction materials
Structure self-waterproofing: p6 or more class resistant to seep concrete, strictly controlled co-optation, irrigation and conservation。

Soft waterproof layer (commonly used):
Extrapolation (recommended): sbs/app modified tar resistant scrolls (polyesters, type ii), viscosified tar resistant scrolls for viscosy polymers, high-molecular mucous film resistant scrolls (prepainted viscos)。
(b) internal/backwater coating: cement-based infiltration of crystal-resistant water coatings, polymer cement protection of water slurry, quality polyurethane waterproof coatings (to be compatible with backwater pressure)。
Sealed materials: polyurethane building seals, water bar (gels) in contact with water expansion, rubber water stopper belts。
Supporting material: base-level processors, glues, unwieldy slabs, protection panels, etc。
Iv. Key construction processes
Preparation for construction:

• cleaning up of garbage, slurry, oil pollution, demodels。
Fixing beehives, holes, cracks (pressure injections or specially designed slurry repair)。
Shrunk up and flattened and the pit filled。
Ensuring solid, flat, clean, dry grass-roots (more stringent requirements for the construction of rolls and a current state of paint)。
On-site survey: conduct a detailed examination of the situation at the grass-roots level (pacing, intensity, cracks, beehives, light water, oil contamination, etc.), leakage points and water sources。
Grassroots treatment:
Materials and instruments: material re-checking is complete and equipment (jetlights, slings, mixers, scrapers, etc.) is in place。
Technical bottom: detailed technical and safe bottoming for construction personnel。
Waterproofing works (for example, external anti-extraposting of sbs rolls):

Blast the baseline, control the width of the connection (long edge 100 mm, short edge 150 mm)。
Thermal smelting works: the flames are evenly heated, the asphalts on the bottom of the scrolls are bright and black, and the flow exhaust is adhesive in time. Burning the scrolls is strictly forbidden。
The adjoining edges are glacial and spill out the molten asphalt to form flat tar bars。
It is smooth and smooth, with no wrinkles, distortions, empty drums。
Yin/ angular angle: make a radius of 50 mm arc or 45 degrees arc with an additional layer width of 500 mm。
Wall-to-wall/set: cleaning of the roots of the tube, embedding with specialized sealed materials, tight additional layers, 250 mm height。
Construction sutures/conformity: strictly designed water-control belts/bars, reinforced by additional perimeter layers。
Rendering: water-free steel plates on both sides or slow-inflating water-inflating strips with additional layer coverage。
Painting of grass-roots processors: evenly painted, bottomless, non-heaping, pending the drying of their watches。

Increased processing of sector nodes:
I've got a big roll to put on:
Protection layer construction:
Baseboard: the 50 mm thick c20 fine rock concrete protection layer is ploughed in a timely manner after acceptance of the waterproof layer。
Side wall: once accepted, a 120 mm brick wall or soft protection layer, such as laminated polyphenyl plates, extruded slabs, is constructed and then filled back。
Backfill:
A layer (300300mm) is filled with clay or ash and artificially insulated from damage to the protective and waterproof layers。
Clearing of hard stones, roots, etc. From the soil。

V. Quality control elements
Material control: entry material must be witnessed for sampling and inspection before it can be used。
Base mass: it is the foundation for water success and failure and must be strictly met。
Quarter node: it's a leak-prone area, which has to be handled in a well-regulated manner, with responsibility。
Connecting and closing: the width of the rolls, the glue quality and the sealing of the head are essential。
Protection of finished products: in the course of construction and in subsequent processes, protection against damage to the water layer。
Process inspection: self-inspection, cross-checking, cross-checking and supervision of key processes by the end of each process。
Closed water test (where applicable): for conditional parts such as waterproofing inside the floor or indoor swimming pools, the closed water test is performed in accordance with the specifications。

Vi. Sustainable construction
Strict compliance with safety protocols, heat-melting construction with fire protection, fire-fighting equipment and good ventilation。
Construction personnel wear qualified safety and security supplies (face masks, gloves, helmets, etc.)。
The material is packed and the site cleared to reduce environmental pollution (especially paint construction)。
Compliance with safety civilization regulations on the ground。
Specializing in waterproofing, trusting the veggies

In relative terms, more and more water-proofing projects are now being phased out as demand rises and cheap rolls are becoming less water-proof (repeated). Retardation of basements not only affects use, but also endangers the safety of structures.
