Reducing noise for housing residents in Darkhouse Lane, Wolves
Tensar reinforced slope systems were used to create a landscaped noise attenuating bund with a narrow base width, enhancing the residential environment with minimum take of usable land.
Benefits
- Residential environment improved by noise reduction
- Steep slopes maintained maximum usable land.
The housing developer wanted to increase property values and improve the living environment by building a barrier to protect new houses from noise from an adjacent road and railway. They needed to minimise the construction footprint and build above a toe slope and tie-in to an existing noise barrier.
The proposed Tensar steep faced reinforced soil systems were constructed on existing ground without any prior treatment. To minimise the construction footprint of the back-to-back earth bund, a different Tensar system was used on each face; a 45-degree TensarTech ® NaturalGreen formed the outer face and a 70 degree TensarTech ® GreenSlope formed the inner face. This allowed the bund to reach the required height with minimal base width, which resulted in reducing land take and enabling tie-in to the existing noise bund at the end. Posts for the closely boarded timber noise barrier were fixed in isolated concrete post foundations, which were accommodated within a reinforced soil zone with careful cutting of geogrid layers for the closely boarded fence as a noise barrier.
