Concrete has been seen as the very embodiment of permanence. We use it to create our sewers, our tunnels, our foundations, and our industrial chemical tanks. But now, under its façade of corrosion resistance beats a relatively soft and chemically prone heart. In aggressive media, such as sulfuric acid, microbial induced corrosion and industrial sewage the attacks are so dramatic that it may not be safe to use bare concrete. To prevent this deterioration, engineers have utilised a state of the art mechanical anchorage system: The HDPE T-Rib liner sheet. This custom geomembrane is not simply draped or glued over a surface, it bonds directly with the substrate itself to form an inextricable part of the structure that will last as long as the building itself.

The Engineering behind HDPE T-Rib

The most difficult part of these prior art coatings, like epoxies or polyurethanes, is their delamination over the years. Concrete moves and lets in air, and water trapped behind that finish can make the concrete bubble, peel. Here the HDPE T-Rib liner sheets bring a revolution to the protection process. These sheets are produced with T-shaped ribs, which is integrated on one side. When wet mix is cast against the liner, these ribs are thus imbedded in the wet mix. When the concrete sets, the liner is compressed into the material. It is not displaced by hydrostatic pressure or loss of gas deliveries, so it’s the ultimate long-term protection for submerge d or high-mo isture environments.

Why HDPE is the Material of Choice for all Landscaping Nursery Containers

High-Density Polyethylene, the material that forms the basis of all HDPE T-Rib liners, is selected for its exceptional chemical resistance. It is not reactive with the majority of acids, bases or salts commonly encountered in municipal waste, industrial runoff and stormwater. In addition, HDPE is pliable and exhibits tensile strength. This will enable the liner to span any minor cracks in the concrete that could occur due over time. The advantage of an HDPE T-Rib liner is that due to its flexibility, it can handle the heat and cold expansion/contraction of a large structure without cracking like rigid materials. Its smooth surface is also the key to keeping its friction coefficient lower, which facilitates fluid flow within pipes and prevents debris or sludge build-up.

An Important Relationship With A Dependable HDPE T-Rib

The performance of a plant depends very much on the quality of the raw material, and precision in rib-extrusion. Dealing with a professional HDPE T-Rib liner manufacturer, you can get sheets that conform to international standard on thickness, rib height and chemical resistance. A good manufacturer will use virgin resins, not recycled, and can maintain UV resistance for about 10 to 15 years. When working on a project of city scale infrastructure, like huge desalination plant or upgrade each pipe in the sewage system, the coherence of his liner sheet protects every square meter of your job from these corrosive forces.

The Simple Installation of The HDPE T-Rib 

These liners are installed in a way which differs from aboveground waterproofing ideal contractors. For new construction the HDPE T-Rib liner is usually fixed to the interior of the formwork before concrete is placed. The ribs are T-shaped in the inward direction to the rebar cage. When the concrete is vibrated or tamped into place, it flows around the ribs and keyways to form a physical bond far stronger than any chemical bond. For pre-cast uses, such as pipes or manholes, the liner is formed in at the factory during manufacture. After the in-situ casting of the concrete, the void between the liner sheets are welded together using hot-air or extrusion welding to form one jointless impermeable interior.

Microbial Induced Corrosion -How to tackle the problem

MIC attacks of the most corrosive sources in a waste water system is one of Microbial Induced Corrosion (MIC). Thiobacillus, a bacterium of the sewage community as well, Help Thrive in sewage localities, their function being to change gas carrying hydrogen sulphide (from our urine) into Sulphuric acid. This acid disintegrates concrete with alarming alacrity, frequently resulting in structural collapse after just a few years. When applied as a lining over the crown of a sewer pipe or wet well walls, HDPE T-Rib provides total barrier to corrosion of concrete by acid. As HDPE is indigestible to bacteria and immune to acid, so the infrastructure's 10-20 year lifespan is now extended to well over 50 or even 100 years… a huge saving in lifecycle costs!

Applicability in Industrial and Civil Domains

Commonly used in wastewater applications, the HDPE T-Rib also has a wide range of other uses. For ore processing plants in the mining industry, we need sturdy and strong leach pads and areas on which chemicals are stored. In the case of food and beverage processing facilities, floors and trenches must be able to resist cycle after cycle of cleaning with caustic chemicals along with thermal shock from hot water. The T-rib construction also prevents the liner from sinking down like other, cheaper models, flush to platform teas of minimum competition height. It creates a sanitary and impervious surface that is quick to clean, while also preventing dirt and debris from permeating the sub floor beneath the concrete pad.

Quality is maintained by means of testing and certification

Every Mahira Polyglobal LLP is tested even before it leaves our plant to withstand the worst of what nature can throw at it. Manufacturers test them for puncture resistance, tear strength and carbon black dispersion (that helps with UV protection). Also an investigation is made into the weldability of the sheet to ensure field seams will be as strong as base material. When engineers call for an HDPE T-Rib liner to be used in their project, they want you to provide documented evidence that the material is able to withstand the specific chemical cocktail it will face. It is this stringent quality control of testing the liners and constancy in manufacture that keeps high-quality standard liners from failing due to an inferior (cheaper) quality.

Conclusion

Selecting a HDPE T-Rib liner sheet is a long term choice of sustainability and protection to our constructed environment. The upfront cost of a liner may be more expensive than pouring bare concrete or using a stripped down paint-on finish, but the rewards over the long term are clear. With no need for maintenance and repair, there will be no worried about leaking on the underground water and structural integrity of important utilities in all future times. In this day when the climate is of particular concern, not only how we build, but what we protect is important. An investment in a good quality HDPE T-Rib liner to safeguard the underpinnings of our world for the generations that follow.
