Residents can now benefit from their homes knowing their houses are on a stable, reinforced slope
Vista Land is the leading homebuilder in the Philippines offering a wide range of housing products to address all income segments. Its subsidiary, Camella Homes provides affordable residential properties with a focus on community lifestyle and living. The recent development of a site in Tagbiliran City, Bohol has been challenged by weak retaining wall structures constructed from cemented boulders (riprap).
To address this issue, Camella Homes worked closely with our engineers to design and construct a suitable alternative wall system. The perimeter slope requiring protection was 60 meters long with an average height of three meters. Bohol, being an island, has limited access to boulder fill for gabion structures. Thus our engineers recommended Green Terramesh as an alternative soil reinforcement solution.
The fact that the fascia of Green Terramesh is compacted soil rather than rocks has resulted in significant savings for Camella. Perhaps more importantly, the client was highly appreciative of the fact that Green Terramesh will support long term growth of vegetation on its angled face.
At the toe of the slope, Reno Mattress was positioned on top of MacTex non-woven geotextile to address possible scouring. Three layers of Green Terramesh with a 72 degree face slope angle were then installed. To ensure sufficient compaction of the soil used in this construction, Field Density Tests (FDTs) were conducted at site.
The contractor for this project, MGS construction commenced work on the retaining wall in January 2019 and completed the structure within four weeks. We provided technical assistance and advice.
Residents can now benefit from homes on top of the new retaining wall in the secure knowledge their houses are on a stable, reinforced slope.
