Civil engineering deals with the design, construction, and maintenance of infrastructure including roads, bridges, dams and buildings.
Geotechnical engineering work to understand how infrastructure interacts with the ground – they deal with foundations, slopes, retaining structures, embankments and tunnels.
Specialist contractors for deep foundations use specific support fluids on their projects.
In order to successfully completing an excavation or a drilling at best cost, engineers need fluids that continually support the excavation, carry cuttings to the surface and permit separation, and increase skin friction.
The fluids need to cause no pollution to the ground and groundwater and must not harm site operatives.
Three types of drilling fluids are used in civil engineering applications:
SNF hydrosoluble polymers are used extensively as performance additives in these applications to boost the performance of bentonite, or for preparation of polymer slurries for bored piles, diaphragm walls, anchors ties, bentonite-cement plastic walls.
Flocculants and coagulants for all types of water treatment and sludge dewatering.
Flobent Bentonite extenders and modifiers bring low-grade betonies into or above API required specifications.
These thinners and dispersants function as a deflocculant, reducing the attraction of clays and drilled solids, which produces high viscosity and gel strengths.
These powder or liquid water retainers absorb large quantities of water or help to reduce fluid losses.
These long chain, high molecular weight polymers are used to encapsulate drilled solids to prevent dispersion and coat shale for inhibition. They can also be used to increase viscosity and reduce fluid loss, or even replace bentonite in certain application such as bored piling.
