Understanding Bitumen Sand Under Tanks: A Comprehensive Guide

Bitumen sand, often referred to as bituminous sand, is a material that has gained significant attention in the construction industry, particularly when it comes to tank installations. This unique material, which combines the properties of bitumen and sand, offers several advantages that make it an ideal choice for tank bases. In this article, we will delve into the various aspects of bitumen sand under tanks, exploring its composition, benefits, installation process, and maintenance requirements.

Composition of Bitumen Sand

Bitumen sand is a composite material that consists of fine sand particles and bitumen, a sticky, black, and highly viscous liquid derived from crude oil. The bitumen acts as a binder, holding the sand particles together, while also providing excellent waterproofing properties. The ratio of bitumen to sand can vary depending on the specific application and desired characteristics of the material.

Benefits of Using Bitumen Sand Under Tanks

There are several advantages to using bitumen sand under tanks, making it a popular choice among engineers and contractors:

• Excellent Waterproofing: Bitumen’s waterproofing properties ensure that the tank remains dry and free from leaks, protecting the contents from moisture damage.

• High Load-Bearing Capacity: The combination of bitumen and sand provides a strong, durable base that can support the weight of the tank and its contents.

• Longevity: Bitumen sand is highly resistant to degradation, making it a long-lasting solution for tank bases.

  

• Environmental Friendly: Bitumen sand is a recyclable material, reducing the environmental impact of construction projects.

Installation Process of Bitumen Sand Under Tanks

The installation process for bitumen sand under tanks involves several key steps:

1. Site Preparation: The area where the tank will be installed must be cleared of any debris and leveled to ensure a smooth and even base.

2. Bitumen Sand Mixing: The bitumen and sand are mixed together in a specific ratio to create the desired consistency. This mixture is then spread evenly over the prepared site.

3. Compaction: The bitumen sand mixture is compacted using a roller or plate compactor to ensure a dense and stable base.

4. Allowing to Cure: After compaction, the bitumen sand needs to cure for a certain period to allow the bitumen to bind the sand particles together and harden.

5. Final Inspection: Once the bitumen sand has cured, the tank can be installed on top. A final inspection is conducted to ensure that the base is level and stable.

Maintenance Requirements of Bitumen Sand Under Tanks

Maintenance of bitumen sand under tanks is relatively straightforward and involves the following steps:

• Regular Inspections: Periodic inspections should be conducted to check for any signs of damage or wear on the bitumen sand base.

• Immediate Repairs: If any damage is detected, it should be repaired promptly to prevent further issues.

• Regular Cleaning: Keeping the bitumen sand base clean can help prevent the growth of algae and other organisms that may compromise its integrity.
