Which standard is implemented in the polymer waterproof construction specification

Legal analysis: the polymer self-adhesive film membrane advocates the construction method of "pre-paving and anti-adhesive", and can be laid on a smooth, firm, and wet base surface without obvious water accumulation, this construction method can not only speed up the construction progress, shorten the construction period, but also help to prevent the common problem of leakage caused by water channeling between the trembling waterproof layer and the base layer of the membrane.

Legal basis: Construction Law of the People's Republic of China Article 53 The State implements a quality system certification system for units engaged in construction activities. Units engaged in construction activities may, in accordance with the principle of voluntariness, apply to the first-class product quality supervision and management department or the certification body recognized by the department authorized by the first-class product quality supervision and management department for the certification of the quality system.

If it is certified, the certification body will issue a quality system certification certificate.

Legal analysis: There are two types of waterproof grades for construction projects: waterproof grades for underground projects and waterproof grades for roofing projects.

The waterproof grade of underground engineering is divided into four levels: level 1: no water seepage is allowed, and there is no wet stain on the surface of the structure; Level 2:

Water leakage is not allowed, and there can be a small amount of wet stains on the surface of the structure; There are a small number of leakage points, and there shall be no line flow and leakage of sediment; If there is a water leakage point, there shall be no line flow and sediment leakage.

Legal basis: Technical Code for Waterproofing of Underground Engineering》 Article 1 In addition to industrial and civil buildings, the new code has greatly improved the standard of waterproof fortification of other underground projects of erection and filial piety, and its wet area shall not be greater than 6 1000 to 2 1000 of the total waterproof area stipulated in the original codeWet stains on any 100 waterproof area should not exceed 4 and reduce to 3. At the same time, the specific requirements for the quantification of leakage water have been added to the tunnel project, and the average leakage should not be greater than, and the leakage on any 100 waterproof area should not be greater.

Make the standard more operable in the implementation of the standard.

The "Residential Design Code" (GB50096-2011) promulgated by the state stipulates that waterproof, moisture-proof and ventilation measures should be taken for basements and semi-basements, and drainage measures should be taken for lighting wells. The roof, floor, exterior walls and exterior windows of the dwelling should be able to prevent rainwater and melting water from entering the interior.

Technical Regulations for Residential Indoor Waterproofing Engineering: Technical Regulations for Residential Indoor Waterproofing Engineering

The moisture content of the insulation material (50 thick poly board) must meet the design requirements, and the quality of the material must meet the requirements of the article, check the factory certificate and retest report. The plate-shaped insulation material is close to the base layer, paved and stable, the seam is tight, and the spacing and width of the exhaust groove are correct when the exhaust groove is set. Allowable deviation of insulation thickness:

5% of the plate insulation material, and not more than 4mm. Find the slope layer The whole cast-in-situ slope layer, mix evenly, lay in layers, compaction is appropriate, the surface is smooth, and the slope is correct. Allowable deviation of slope thickness:

The overall cast-in-situ slope finding layer is +10%, -5%. The spacing and width of the lattice seams are correct. The drainage slope of the screed layer must meet the design requirements, and the cement mortar screed layer should be smooth and calendered, and there should be no crisp and loose and peeling phenomenon.

The position and spacing of the screed lattice joints should meet the design requirements, and the allowable deviation of the surface flatness of the screed layer is 5mm. Waterproof layer The waterproof layer of the membrane shall not have leakage and water accumulation, and the detailed waterproof structure must meet the design requirements. The lap joints of the waterproof layer of the membrane are firmly bonded and tightly sealed, and there must be no defects such as wrinkles, warping edges and bubbling.

The end of the waterproofing membrane should be bonded with the base and fixed firmly, the seam should be tightly sealed, and the direction of the membrane should be correct. The ends of gutters, gutters, cornices, flooding and façade membranes should be cut neatly, stuffed into the reserved grooves, and fixed with metal strip nails, with a maximum nail spacing of no more than 900mm, and sealed tightly with sealing materials. The permissible deviation of the lap joint of the coil is -10mm.

Protective layerThe protective layer of silver paint should be firmly pasted with the coil, and the thickness should be uniform, and the coating should not be missed. The color cement brick protection is firmly pasted, the color is uniform, the surface is clean, the area of the lattice joint is not more than 100m2, and the width of the lattice joint meets the requirements.

New and old building walls, kitchens, bathrooms, window sills and other moisture-proof and waterproof treatment.

Various pools and basements are treated in the way of anti-seepage.

Cement-based interface treatment agent to improve the bonding performance of mortar layer with cement concrete, aerated concrete and other materials.

Legal analysis: The specific air requirements of the membrane waterproof construction specification are:

1. Ensure that the flatness, slope, surface dust, sand and debris of the construction surface are cleaned up;

2. The details include the exhaust pipe, the lattice seepage joint, and the roof water pipe retention requirements;

3. The strengthening of the waterproof layer at the detail point, on the same elevation operation surface, should follow the principle of shouting the first difficult and then easy, when laying a large area of waterproof membrane, lay the low place first, then lay the high place, and finally lay the protruding parts such as the surface.

According to the relevant laws and regulations, construction activities shall ensure the quality and safety of construction projects, and comply with national construction safety standards.

Legal basis: Construction Law of the People's Republic of China

Article 3 Construction activities shall ensure the quality and safety of construction projects, and comply with national construction safety standards.
