Project Description

Road construction on an organic soil

The Ring Express road joins the existing 3-city Bypass (Gdańsk, Sopot and Gdynia) and the Highway A1 (Gdańsk – Katowice) in the North of Poland.

This area had extremely bad soils conditions for road construction. There was very organic soil (peat and sludge) with high water content index. The thickness of weak deposits varied from 6 to 25 m with average depth of 12 m.

Two ground improvement methods were proposed: Controlled Modulus Columns and pre-consolidation treatments using vertical drain with surcharge. This solution fulfilled the technical and economical requirement of the investor.

The Menard Group develops foundation solutions based on ground improvement and reinforcement technologies. Its treatments eliminate the need for the deep foundations traditionally used to support surface structures.
