Case Study: Effective Waterproofing with Dimple Board in Chikhali, Pune

Introduction:

Waterproofing plays a critical role in infrastructure development, ensuring the longevity and structural integrity of buildings, basements, tunnels, and other constructions. As a leading geosynthetics manufacturer and supplier, Ocean Non Wovens understands the importance of effective waterproofing solutions. In a recent project in Chikhali, Pune, we supplied and used 12,972 Sqm of Dimple Board, delivering a reliable and durable waterproofing solution that met the client’s requirements. This blog delves into the project details, the role of Dimple Board in waterproofing, and insights that are often overlooked when considering such solutions.

Understanding Waterproofing and Its Importance

Waterproofing involves making a structure water-resistant, preventing water from penetrating through walls, floors, and foundations. It is a critical component in construction, especially in areas prone to heavy rainfall or where structures are below ground level. Effective waterproofing protects buildings from moisture-related issues such as structural weakening, mold growth, and internal damage. According to a report by Grand View Research, the global waterproofing market is expected to reach USD 72.6 billion by 2025, highlighting the increasing demand for high-quality waterproofing solutions.

Dimple Board: A Comprehensive Waterproofing Solution

Dimple Boards, also known as drainage boards, are geosynthetic materials designed with a unique dimpled pattern that creates air gaps between the board and the waterproofing surface. This design allows water to drain efficiently, reducing hydrostatic pressure against the structure’s walls. Here’s how Dimple Board contributes to effective waterproofing:

1. Drainage and Moisture Control: The dimpled pattern in the Dimple Board facilitates efficient water drainage, preventing water accumulation around the structure. This feature is particularly important for basements and underground structures, where hydrostatic pressure can damage walls and foundations. By allowing water to drain away from the surface, Dimple Boards help maintain a dry and stable environment.
2. Protection of Waterproofing Membranes: Dimple Boards act as a protective layer over waterproofing membranes, shielding them from damage caused by sharp objects, backfill soil, and mechanical impacts during construction. This protection extends the lifespan of waterproofing systems, ensuring long-term effectiveness.
3. Enhanced Load-Bearing Capacity: The Dimple Board’s design not only aids in drainage but also provides structural support, distributing the load evenly over the waterproofing layer. This is especially beneficial in areas with heavy soil pressure, as it helps prevent the deformation or puncturing of the waterproofing membrane.
4. Eco-Friendly Solution: Dimple Boards are typically made from high-density polyethylene (HDPE), a recyclable and eco-friendly material. Their long lifespan and durability reduce the need for frequent replacements, contributing to a sustainable construction approach. The environmental benefits of using HDPE materials in construction are well-documented, making Dimple Boards an ideal choice for modern projects.

Project Overview: Waterproofing in Chikhali, Pune

The Chikhali project involved the installation of 12,972 Sqm of Dimple Board as part of a comprehensive waterproofing system for a large commercial structure. The site faced significant waterproofing challenges due to its below-ground construction and the high groundwater table in the area. Traditional waterproofing methods alone were insufficient to handle the pressure and moisture levels, necessitating a more robust solution.

Installation Process

The installation of Dimple Board at the Chikhali site followed a systematic approach:
Surface Preparation: The substrate was cleaned and primed to ensure proper adhesion of the waterproofing membrane. This step is crucial as it prevents any debris from affecting the membrane’s integrity.
Membrane Application: A high-quality waterproofing membrane was applied to the surface to create a water-resistant barrier. The membrane serves as the primary defense against moisture intrusion.
Dimple Board Placement: The Dimple Board was then installed over the membrane, with the dimples facing outward. This orientation allows water to flow freely through the channels created by the dimples, directing it towards designated drainage points.
Backfilling: After installing the Dimple Board, backfilling was done carefully to ensure that the board remained in place without any damage. The backfill material was compacted to avoid pressure buildup that could compromise the waterproofing layer.

Data Insights: Why Dimple Boards Outperform Traditional Methods

Dimple Boards provide several advantages over traditional waterproofing methods such as bituminous coatings or liquid membranes. Studies have shown that structures using Dimple Boards for drainage experience up to 30% less hydrostatic pressure compared to those using only conventional waterproofing methods. This reduction in pressure translates to lower maintenance costs and increased structural stability over time.

Moreover, the installation of Dimple Boards is faster and more efficient, reducing labor costs and construction time. A survey conducted by Construction Research Council found that projects utilizing modern drainage boards like Dimple Boards had an average of 15% faster completion time. This efficiency makes Dimple Boards an attractive option for large-scale projects like the one in Chikhali.

Overlooked Aspects of Dimple Boards in Waterproofing

While many companies emphasize the drainage capabilities of Dimple Boards, there are lesser-known benefits that contribute to their effectiveness:
Thermal Insulation: The air gap created by the dimpled design provides a degree of thermal insulation, helping to maintain stable temperatures within the structure. This can be particularly beneficial in reducing energy costs for underground structures.
Vapor Barrier Capability: When used with a vapor barrier layer, Dimple Boards can prevent moisture vapor from seeping through walls and floors, which is essential in maintaining indoor air quality and preventing mold growth.
Versatility in Application: Dimple Boards are highly versatile and can be used in a variety of settings, from green roofs to retaining walls and foundation slabs. This adaptability makes them suitable for diverse projects, beyond just basement waterproofing.

Project Outcome: Success in Chikhali, Pune

The implementation of Dimple Board in Chikhali resulted in a highly effective waterproofing solution that exceeded the client’s expectations. Post-installation inspections revealed no signs of moisture penetration or damage to the waterproofing membrane, ensuring a dry and safe environment for the structure. The client appreciated the durability and cost-effectiveness of the solution, as it minimized long-term maintenance requirements.

Our use of Dimple Board not only addressed the immediate waterproofing needs but also added value through its durability, protection of the membrane, and additional benefits like thermal insulation. The project stands as a testament to the effectiveness of modern geosynthetic materials in tackling complex waterproofing challenges.
