Features

Features of HDPE Dimple / Drainage Board

The shape of material makeup and HDPE Dimple / Drainage Board in India gives them many unique features:

Dimpled Structure: The most specific aspect is a set of high caves or spikes with one or both surfaces of the sheet. These give a continuous air difference on the Dimples installation, which acts as a very effective drainage channel. The height of these caves varies, but often affects between 6 mm to 20 mm or more drainage capacity.

High-Density Polyethylene (HDPE) Material: HDPE at the origin of the board is a strong and long -lasting thermoplastic polymer. The shape of material makeup and HDPE dimple drainage trays gives them many unique features:  HDPE provides:

Excellent Chemical Resistance: It has a excessive degree of resistance to enormous numbers of chemical compounds, acids, alkalis, salts, and organic degradation found in soil and groundwater, so it is able to make certain long-time period performance.

Durability and Longevity: HDPE is recognized for its lengthy service life, with resistance to environmental degradation, punctures, and root penetration.

Impermeability: While designed for drainage, the solid HDPE sheet itself acts as an impermeable barrier to water and vapor, imparting a further layer of waterproofing safety

Integrated Geotextile Layer (Optional but Standard): Most HDPE dimple boards have a non-woven geotextile fabric heat bonded to the crests of the dimples on one face. Such a geotextile functions as a filter that will allow water to enter into the drainage void but will keep fine soil particles from entering into and clogging the drainage channels.

Root Barrier: The thick HDPE material and the structure form a good barrier against roots of plants, stopping them from puncturing waterproofing membranes or growing into the structure.

Vapor Barrier: The solid HDPE core is also used as a vapor barrier to stop moisture migration into structures from the ground.

Lightweight and Flexible: Although strong, HDPE dimple boards are comparatively lightweight and provided in rolls for easy handling, transportation, and on-site installation. They can adapt to uneven surfaces.

Temperature Resistance: They continue to perform well in a wide spectrum of temperatures, usually between -30°C and +80°C.

Advantages

Benefits of HDPE Dimple / Drainage Board

The synergy of properties of HDPE dimple drainage boards has several benefits in different building situations:

Improved Drainage Efficiency: The persistent void generated by the dimples facilitates prompt and effective in-plane draining of water, relieving hydrostatic pressure on buildings and forestalling water pooling.

Waterproofing Membrane Protection: The dimpled board is a protective cover that prevents fragile waterproofing membranes from mechanical damage when backfilling, future soil settlement, and root intrusion. This prolongs the waterproofing system's lifespan.

Decreased Hydrostatic Pressure: In a way of draining water from the structure, dimple boards remove or minimize hydrostatic pressure, one of the primary reasons for dampness, leaks, and structural damage in basements, retaining walls, and underground structures.

Savings in Time and Cost:

Replaces Granular Drainage: They do away with the use of heavy and costly granular drainage material such as crushed stone or gravel, saving material costs, transportation, and excavation.

Increased Installation Speed: Being light and delivered in rolls, they are easy and fast to install, saving on HDPE Dimple / Drainage Board Price India and project duration altogether.

Decreased Wall Thickness: In certain instances, the effective drainage can provide for decreased structural wall thickness, also saving material expenses.

Increased Breathability: The air gap generated by the dimples enables the circulation of air behind the waterproofing membrane, enhancing drying of incidental water and minimizing condensation and mold growth within the structure.

Environmental Advantages: By minimizing quarrying and transportation of natural aggregates, they are a lower carbon option and more environmentally friendly construction solution.

Flexibility: Supplied in a range of dimple heights and with or without geotextile, they can be specified to meet specific drainage and protection needs.

Durability: The natural durability and chemical resistance of HDPE provide a long service life with low maintenance.

Applications

Uses of HDPE Dimple / Drainage Board

HDPE dimple drainage boards find wide use in a broad range of civil engineering and building applications:

Basement and Foundation Walls: The most universal application. Installed vertically against exterior basement walls and foundations, they shield the waterproofing membrane and offer continuous drainage, averting hydrostatic pressure development and dampness.

Retaining Walls: Employed to the rear of retaining walls to ease hydrostatic pressure, provide stability, and avoid the bowing or cracking of the wall from water buildup.

Underground Structures: Needed in tunnels, underground parking garages, subway terminals, and utility corridors for the management of groundwater and safeguarding the structural integrity.

Roof Gardens and Green Roofs: Essential for effective drainage of surplus water from the planting medium, avoiding waterlogging and shielding the structural roof slab against root intrusion and extended exposure to moisture. They assist in the production of a healthy growing medium as well as protecting the building.

Podium Decks and Plaza Decks: Analogous to roof gardens, they give way to drainage under paved or landscaped sections constructed over occupied spaces.

Civil Works and Landscaping:

Sports Fields: Employed under artificial turf or grass sports fields to provide quick drainage and playability.

Road and Railway Embankments: For subsurface drainage to control groundwater and increase stability.

Landfill Caps: Employed together with geomembranes to control gas ventilation and surface water drainage.

Planter Boxes: To effectively drain large planter boxes in cities.

Under-Slab Drainage: Employed under concrete slabs at grade to control rising damp or ground water, sheltering the slab and interior areas.

Tunnel Lining Protection: Offering drainage and protection to the main waterproofing membrane in tunnel engineering.

Specification

Specifications of HDPE Dimple / Drainage Board

Important specifications for HDPE dimple drainage boards are:

Fabric: High-Density Polyethylene (HDPE), sporadically integrating a polypropylene (PP) geotextile.

Dimple Height / Thickness: This is a very important parameter since it determines the air gap and therefore the drainage volume. Standard heights are 6mm, 8mm, 10mm, 13mm, 15mm, and 20mm. The typical board thickness will be slightly greater than the dimple height.

Roll Dimensions: Usually supplied in rolls having a width between 1 meter and 4 meters, and length from 10 meters up to 50 meters or longer.

Weight (GSM - Grams per Square Meter): Comparative to the fabric’s weight and strength.31 Standard values are usually from 400 gsm to 1200 gsm, and the higher the GSM, the higher the strength and durability.
