Dimple Drainage Board
Unlike air gap membranes, dimpled drain sheets can be mechanically fastened and are not impacted by shifting, cracking and settling of the concrete foundation wall. They can also withstand standard backfilling without leaking.
Builders can install them in any weather, extending the working season beyond that of fluid-applied waterproofing products.
Easy to Install
Dimple membranes are a great below-grade drainage solution. They are lightweight, and install quickly – cutting labour costs and accelerating project timelines. They are also very versatile — and can be used on everything from small residential basements to enormous commercial projects extending 50 feet below grade.
Typically, builders install the dimpled membrane along with the waterproofing and insulation to prevent water from entering the walls from the backfill. The membrane is perforated to allow for drainage and a layer of geotextile is bonded to the dimples to keep soil from blocking the passage of water. The membrane is then mechanically fastened to the wall, using a series of washers placed at regular intervals around the perimeter.
This enables the water to travel down the drains and reduces the hydrostatic pressure within the footer, protecting against basement leaks and structural damage. The membranes are also available in 8-foot rolls for faster installation and fewer seams, and they can be installed vertically or horizontally. For best results, installers should follow the installation guidelines provided by their dimple membrane supplier. These guidelines will ensure a strong, long-lasting installation that can withstand years of use and abuse. Indokon’s dimple membrane systems are also environmentally friendly, reducing the need for extensive aggregate drainage layers and contributing to overall sustainability. They are also resistant to chemicals and roots, ensuring they can be used for a number of years before needing replacement.
Versatile
Dimple membranes can be installed in a variety of ways to meet different needs. For example, when waterproofing is needed on an elevated walkway or parking garage, a perforated dimple sheet can replace a gravel layer and direct water to floor drains inside the slab. This helps to prevent water from pooling and evaporating, which can damage the waterproofing system. In addition, this allows the installer to save on material costs by reducing the need for aggregate.
These products can also be used to create a basement waterproofing system. By forming an impermeable barrier and directing moisture to interior footing drains, they can protect the building from groundwater seepage and other issues. In addition, they can help to reduce the risk of mold and other toxic materials.
Another advantage of these products is that they can be used in any weather, unlike fluid-applied membranes. This means that they can be installed during rain, snow, or freezing temperatures, and even after the foundation has been poured. This can Plastic Dimple Drainage Board greatly speed up construction and allow projects to be completed sooner than would otherwise be possible.
Dimple membranes are also a popular choice for drainage solutions in horizontal applications. In these cases, the product is installed with the dimples facing up, and a geotextile is bonded to it to keep soil out of the dimpled surface. This allows the membrane to be used for sidewalks, plaza decks, and other projects where a traditional gravel drainage layer would be impractical.
Durable
Dimple drainage boards provide a durable, long-term solution to hydrostatic pressure against basement walls. They promote water flow and prevent soil contaminants from entering the foundation. They also protect against vapors and condensation that can cause damage to the basement wall, extending the waterproofing membrane’s lifespan.
Plastic drainage boards consist of a heavy duty polymeric sheet cuspated under heat and pressure to form the dimpled core. The core is bonded to a layer of root resistant, non-woven geotextile fabric. The product is available in both perforated and impermeable sheets.
Perforated drain sheets are designed to work in conjunction with waterproofing membranes to create a drainage system in both vertical and horizontal applications. They offer many of the same benefits as air gap membranes, including durability and ease of installation. They are commonly used in basements, but can be installed in green roofs, parking decks, and retaining walls.
Like air gap membranes, perforated dimpled sheets are installed with the dimples facing up and the geotextile down. The dimples provide a drainage path for moisture that can be directed down to footing drains or through the interior floor drains in basements. Perforated drainage sheets can also be used as a vapor barrier for crawl spaces, keeping moisture and vapors away from the foundation walls. In addition, they can be used to prevent soil and backfill materials from touching the walls in exterior applications.
Environmentally Friendly
The dimple portion of this membrane produces an air gap, allowing soil and moisture to pass through. This helps prevent water accumulation, which can damage foundations and cause basement leaks. It also allows for efficient drainage of water, reducing the risk of hydrostatic pressure.
This membrane is an environmentally friendly option for many construction projects. It does not release High quality drainage membrane volatile organic compounds (VOCs) during its production, which helps protect the surrounding environment. It is also easy to install, making it a popular choice for residential and commercial foundations and other underground applications. It can also be used in landscape projects, such as garage roof greening, rooftop gardens and football fields.
These membranes are also durable and versatile, which means they can be installed in a variety of weather conditions. They can be used in place of gravel layers, and they can provide an effective barrier against groundwater intrusion. In addition, they can be used in conjunction with other waterproofing products, such as polyurethane or liquid membranes.
Unlike fluid-applied membranes, which require warm temperatures and dry surfaces, these membranes can be applied in rain, snow or freezing temperatures. This allows contractors to work later into the winter and earlier in spring, and it also eliminates the need for expensive tarps. They are also cost-effective, as they reduce the need for gravel and other costly materials, while providing significant long-term savings.
