HDPE Drain Cell Dimple Geomembrane

During construction and during the structure’s normal use, HDPE Drain Cell Dimple Board plays an essential role in ensuring a reliable drainage system. The specialized dimpled membrane allows moisture to flow freely, eliminating the risk of hydrostatic pressure building up against the foundation.

It is also suitable for: landscape engineering (garden, garage top greening), planting roof drainage ventilation and basement waterproofing.

Product Description

HDPE Drain cell Dimple Membrane plays an important role during construction period and the normal use HDPE Dimple Geomembrane of the structure. Together with drain and porous water pipe or non woven geotextile, it can form an efficient drainage system. It also reduces hydrostatic pressure on the waterproof layer, thus ensuring initiative waterproof.

The unique design of this drainage membrane facilitates quick and efficient water flow, thereby protecting structures against damage caused by excessive moisture. This drainage membrane also allows excess water to escape easily, preventing the buildup of hydrostatic pressure against the foundation.

This product is made from high density polyethylene plastic, with the surface covered by a filtration geotextile. Its dimples are in cylinder and semi cone shape, and are arranged in a spatial structure with certain height, and can resist long-term high pressure without deformation.

This drainage membrane can be used for a wide range of applications, including landscaping, greening project, highway basement, railway basement and slope protection layer. Whether you need it for a building foundation or other civil engineering projects, All Metal India can supply premium-quality HDPE drain cell dimple membrane that will meet your requirements.

Applications

The HDPE Drain Cell Dimple Sheet 400 GSM (also known as Concave Convex Drainage Board) plays an important role in civil construction projects by creating a good drainage system. It can effectively export excess water to avoid problems like waterlogging, which can lead to damage of the construction or its surroundings. It can be used for both the construction period and the structure’s normal use, making it an indispensable component in any civil engineering project.

It is a waterproofing membrane that has a unique dimpled design, which creates an air gap between the foundation and the surface below it. This allows for the quick and efficient flow of water, preventing hydrostatic pressure from building up against the foundation. It is also resistant to a wide range of chemicals, making it suitable for various applications.

The waterproofing membrane can be used for numerous applications, including landscaping, municipal engineering, and construction engineering. It can be laid on the ground in a variety of ways, depending on the specific installation requirements and conditions. It is a flexible and durable material that can be cut to size with a utility knife, and it can be joined together using special fasteners. It can be used in conjunction with other products, such as geotextiles and liners, to create a complete water management system for any application.

Installation Method

A high-density polyethylene geomembrane is an ideal solution for projects that require a watertight protective layer. It is resistant to chemicals and has a high stress factor making it perfect for use in SUDS applications such as attenuation tanks, pond lining, anaerobic digestion applications, porous sub-base installations and containment. It can also be used in structural waterproofing applications such as lining cut-off trenches.

When installing a geomembrane, it is important that you follow the manufacturer’s installation guidelines. These will outline the best methods for installation, including preparing the subgrade and testing the permeability of the membrane. These guidelines will help you ensure that the liner is installed correctly and meets project specifications. It is also important to check that the liner passes quality control tests before it is delivered to site.

Before installation, the surface of the geomembrane should be treated to remove any sharp hard objects and to ensure that it is free from debris that could damage it. The membrane should then be anchored to the ground using an appropriate method, such as anchoring rods or soil nails.

Once the membrane is in place, it can be welded together using an appropriate welding technique. Fusion welding is usually the preferred method as it produces a stronger weld than extrusion welding. It is important to weld the membrane when the temperature is above 0°C and to make sure that there are no environmental restrictions.

Maintenance

The specialized dimple pattern of this foundation membrane allows for easy water drainage and prevents structural damage due to moisture. Its structure also promotes air circulation and 3D Drainage Geomat provides rear ventilation of the foundation walls. It is a high-density polyethylene material, resistant to a wide variety of chemicals and capable of withstand high stress factors. It can be installed underneath petroleum tanks, anaerobic digestion applications, porous sub-base installations and containment.

The durability of HDPE geomembranes can be influenced by several different factors, including temperature and soil conditions. A large scale centrifuge test of a landfill-lined waste facility subjected to both downdrag waste settlement and seismic loading has been conducted to help validate a numerical model for performance based design of geomembrane liner systems.

It was found that the permeability of HDPE geomembranes increased with increasing temperature. The permeability was proportional to the square root of the thickness of the geomembrane. The results of this study suggest that the permeability of HDPE geomembranes should be evaluated prior to their installation in order to determine their suitability for a particular project site.

The gradual failure of HDPE geomembranes in service was investigated by conducting four dynamic corrosion tests with various temperatures and durations. It was found that the tension and puncture strengths of HDPE geomembranes decreased with increasing corrosion duration, with the tensile strength in the longitudinal grain direction being significantly higher than that in the transverse direction.
