Civil engineering involves planning, design, construction, maintenance, and infrastructure operations, and they are all part of our daily lives.
Geotechnical Engineering analyzes existing subsurface conditions and materials before designing deep foundations such as bored piles, barrettes, and diaphragm walls for tall buildings, bentonite-cement plastic walls, wastewater tunnels, metro lines, and train stations.
Contractors specialized in deep foundations are using specific support fluids to complete projects. Completing an excavation or drilling at optimal cost depends on the properties of drilling fluids and additives to achieve several purposes, such as:
- Carrying cuttings to the surface and easing solid-liquid separation
- Maintaining continuous borehole integrity during excavation
- Preventing fluid loss
- Ensuring compatibility with other construction materials, such as concrete and reinforced steel bars
- Preventing pollution of the ground or groundwater and enhancing the safety of site operators
- 100% polymer-based when drilled shaft lateral skin friction is part of the design and/or when drilling in water table
- Mixed drilling mud based on bentonite and water-soluble polymers
- Anti-Clay Swelling Agents
- Borehole Cleaners
- Dispersants and Mud Thinners
- Viscosifiers
- Lost Circulation Material
- Plugging Agents
