Natural Vegetation

Gabion Wall

Precast Panel

recent advances in materials and manufacturing technology have made
possible for PGATECH to reinforce MSE fills with HDPE E’Grid Uniaxial Geogrids

soil nailing is a practical and proven technique that serves as a means of
passively reinforcing the soil to make it more stable by reinforcing the ground
with small diameter rebars known as "nails“ protected with a structural facing

if soil nailing is inadequate per design requirements, PGATECH also offers
ground anchoring as an alternative solution

applications: excavation protection, slope stabilization, and retaining walls

that has been widely used as a method of ground improvement due to its rapid
and easy-installation process, load carrying capability, and applicability to a
diverge range of soil conditions

the advantage and the technical superiority of JSP over the conventional jet
grouting is in its specialized nozzle design which utilizes the "double fluid
system“, making penetration and fracturing of the soil mass effective resulting to
a pile diameter that ranges from 0.80m to 1.2m, depending on the type of soil
