HDPE Autoadhesiva Membranas impermeabilizantes - Tipo soldable

welded HDPE

Descripción del producto

Welded High density Polyethylene self adhesive waterproofing membrana it "adopts the pre-laying construction technology" and can be welded waterproofing membrana, after the membrana bonds with the concrete it forms an integral seal with prevents laterals water migration, the waterproof effect is not affected by building settlement, reinforcement can be directly laid on top of the membrana and it doesnot require screed protection.
In this roling material, the extruded sheet of modiied polyethylene resin is made as the main waterproof material, while the water-soluble isolation material is adopted as the waterproof bonding layer, and then the protective layer of polyethylene membrana is covered to form the polymer waterproof rolling material.

Características del producto

* las juntas y solapamientos se soldan en caliente para garantizar que no haya fugas a través de las juntas de regazo

* la pre-colocación y la tecnología de Unión inversa del producto. La pre-colocación y la tecnología de Unión inversa se adopta para formar una integración con el hormigón estructural del pie trasero, de modo que el problema de la tradicional impermeable envuelta puede ser resuelto

*La lámina de alta resistencia soporta eficazmente grietas y perforaciones sin necesidad de una capa protectora adicional. Tras colocar la armadura, puede verterse el hormigón.

*High bonding strength. The product can form a permanent bond with concrete. I has a higher bonding strength and excellent efect of water retention, so that the leakage probability can be effectively reduced.

*Prevent any destruction of sedimentation. As known, the traditional waterproof layer will be torn by any foundation settlement or subsidence   of protective layer. However, the pre-laying & reversely bonding material can be bonded with the structure to prevent any destruction of           sedimentation.

*Material ligero y fácil de instalar. Con un espesor de 1,2 mm permite alcanzar una impermeabilización de grado A y puede colocarse rápidamente por dos operarios en superficies simples o complejas. 

*Waterproof for all weather use. The construction can be done in the muliple environments of rainy season, summer and winter etc. 

*Shorten the construction period. The requirement for formation level is not high, and the structure layer is less. The construction is quick and convenient. The construction period will be shortened to over 10 days than that of common roling material.

*El material presenta alta resistencia al pelado y al desgarro, buena resistencia a la hidrólisis y excelente flexibilidad a bajas temperaturas.

*The construction process does not need any solvent or fuel. It is green, safe and environmentally friendly.

The water-soluble isolation material is adopted as the waterproof bonding layer. After it is contacted with the wet concrete, the isolation material will be dissolved and disappeared. The self-adhesive layer of rolling material is directly bonded with the concrete. The bonding strength is high and the effect of anti -water breakthrough is good.

Scope of application

Aplicable a obras de impermeabilización de metros, túneles, depósitos, canales, vertederos, plantas de tratamiento de aguas y plantas químicas, así como a soleras y muros enterrados de edificios industriales y civiles mediante tecnología preaplicada de adherencia inversa.

Aplicación

Treatment of construction base surface

The construction base surface shall be treated. The base shall be flat, solid, free of sharp convex objects, and the surface of the base surface shall be free of pooled water.

La construcción del rollo impermeable

Concrete is poured backward on the sand side of the roll materials.The short side shall be overlapped in a staggered manner, and the staggered position shall not be less than 1/3 of the width, so as to prevent the short side from overlapping in the same position.The HDPE membranas are welded together by hot welded the width of lap sides 100mm, Before welded, keep the suface of HDPE film clear.The coiled material shall be lapped by means of hot wedge welding, and the lapping width shall be 100mm. Before welding, it shall be ensured that the lapping part is free of pollution. For single weld systems, the weld seam dimensions of the end and edge seams of the sheet should be at least 50mm. for double seam welding systems, it consists of two parallel weld seams 15mm wide, with a 20mm air duct gap between the two weld seams.Please weld with difference temperature and speed to choose the best one.(suggest:250°C, speed 1.5m; 300°C, speed 2.5m. 400°C, speed 3m etc)After welding, the overlapping area shall be covered with HDPE matched tapeThe waterproof roll shall be fixed on the concrete base in advance for the welding vertical to the base.The treatment of internal and external corners shall be carried out by means of prefabricated components of the supplier or cut the membrana and hot air welding on site.

inspección

Check the overall apparent quality, overlapping quality, local node treatment and other items of the waterproofing membrana. If any quality defect is found, it shall be repaired immediately

Precautions

Construction is not allowed in rainy and snowy days and strong winds above Grade 5.The temperature of the construction environment should not be lower than 5°CThe base course is required to be flatDuring the material laying period, the completed area should be well protected to prevent the material rom being contaminated, which may affect the bonding strength with the structural concrete in the later stage

Storage conditions

The height of horizontal storage for the rolling material shall not be over five layers, and the roling material shall be stacked in a single layer when it is vertically storagedAvoid the sun, avoid the rain and pay attention to the ventilation. The ambient temperature should not be higher than 45 °C, and the relative humidity should not be over 80%.When they are stored at the same time, the multiple types and specifications of products should be separately placed according to the different types and specifications, and should not be mixed to prevent any misuseUnder the normal storage conditions, the warranty period of product is 1 year since the date of production. After the expiration date, the recheck and confirm of product that the test is qualified must be done before any use of product.
