1. 📌Introduction to Barret wall drill
In the current construction context, the need for solutions for deep foundation construction is sure, modern, again guaranteed technical safety increasingly high. One of the advanced technologies that is widely used in developed countries, especially in the US and Japan, is Barret wall drilling technique combined with steel lowering according to American standardsIn Vietnam, Le Thy Construction Company is a pioneer in effectively implementing this technology in many large projects.

2.🔎 What is Barret wall drilling?
Barret Wall Drill (Barrette Wall or Barrette Pile) is a modern deep foundation construction method, using a specialized scraper to create rectangular vertical trenches in the ground. Then, High strength steel cage will be lowered into these grooves, before pouring concrete using Tremie pipes to complete the structure.
Compared with the traditional bored pile method, Barret wall has many outstanding advantages such as:
👉 High water resistance, effective support for underground works or near groundwater areas.
👉 Larger load due to wider cross section.
👉 Continuous and uniform wall – especially suitable for deep basements.
3.🏗️ Lowering steel according to American standards - Ensuring high quality and safety
An important element in the structure of the Barret wall is the steel core – the main load-bearing frame of the reinforced concrete structure. At Le Thy Company, the steel used meets international standards, especially ASTM A615 and ASTM A706 of the US – two standards commonly applied in large-scale infrastructure projects:
✅ ASTM A615: high strength steel, used in foundation and bridge construction.
✅ ASTM A706: steel has ductility and resistance to seismic conditions, suitable for structures that need to be vibration-proof or operate in earthquake zones.
– Standard steel bottom construction will help ensure:
– Perfect bonding ability between steel and concrete,
– Minimizes the risk of rust, cracking,
– Extend the life of the project to decades.
4.🔄 Barret wall drilling and scraping construction process
🔹Step 1: Prepare for construction
– Locate and prepare the site.
– Install scraper and retaining solution.
🔹Step 2: Drill the groove
– Drill according to design, ensuring stable wall.
– Check the size and depth of the drilled groove.
🔹Step 3: Lower the steel core according to US standards
– Use steel that meets ASTM A615/A706 standards.
– Make sure the steel cage is lowered into the correct position and securely fixed.
🔹Step 4: Pour concrete with Tremie pipe
– Continuously poured concrete, meeting ASTM C94/C94M standards.
– Ensure uniform structure, no stratification.
✅ Outstanding advantages of this technology
The combination of Barret wall drilling and steel lowering according to American standards brings many benefits:
🛠️ Extremely strong, meeting the strict requirements of high-rise buildings and deep basements.
🌊 Effective waterproofing, suitable for areas with underground water.
🔇 Low vibration, low noise, suitable for construction in densely populated urban areas.
⏱️ Fast construction, optimizing time and investment costs.
5. 📌 Practical application
– High-rise buildings: Increases nail strength.
– Metro line, underground tunnel: Ensure structural safety.
– Coastal construction: Good resistance in salt water environment.
