WBQ Ground Screw Foundations
High Strength ● Faster Installation ● Lower Project Cost
As a new type of foundation, WBQ spiral ground piles deliver a high-strength, engineered solution suitable for a wide range of applications—including solar projects, timber structures, fencing systems, light-steel buildings, and other modular constructions. By eliminating excavation, concrete pouring, and heavy logistics, WBQ ground screws significantly accelerate installation and reduce overall project costs.
With minimal disturbance to soil layers and surrounding vegetation, WBQ foundations provide a faster, cleaner, and more sustainable alternative to traditional methods—while ensuring proven load performance and long service life.
WBQ is a contributing member to the development of China’s national standard GB50135-2019 for ground screw foundations.
ECOLOGICAL & ENVIRONMENTAL PROTECTION
No excavation or concrete pouring required; minimal disturbance to soil and vegetation, with zero mud, slag, or dust pollution.
EFFICIENT CONSTRUCTION
Quick installation using the screw-in principle; upper structures can be mounted immediately without curing.
COST SAVINGS
Materials and construction cost about one-third of steel-concrete; eliminates waiting and curing time.
RECYCLING
Piles can be removed and reused without harming green spaces, supporting flexible relocation.
ALL WEATHER CONSTRUCTION
Installation possible in rain, snow, freezing, or dry conditions without affecting progress.
MULTI SITE APPLICATION
Suitable for swamps, slopes, rivers, narrow spaces, and complex pipelines where conventional methods are difficult.
