Retaining Walls


Retaining walls may be constructed various materials, traditionally stone and reinforced concrete, also gabions. However these can fail due to the amount of soil water pressure behind them, freezing and expansion soon finds the weaknesses. Even gabions can fail from corrosion.

Retaining walls also require complex calculations (typically over 30 pages of calcs) to ensure they are designed to withstand the substantial pressure of the soil and water they retain. These should be undertaken by a structural engineer, who can check each stage of construction and issue a Structural Adequacy Certificate on satisfactory completion. This ensures the retainer is fit for purpose and can help alleviate long term and even more costly problems later when selling and concerns regarding subsidence.

Retaining walls can be constructed or repaired with geotechnical construction techniques. Soldier piles with lagging, sheet piles, secant piles, tangent piles, and diaphragm walls use structural members to resist lateral pressures from retained soil and adjacent structures.

Some of the retaining wall tasks that Killeroran Civil & Construction is involved with include:
